5 Stage Cascade Made in Germany !

[sdumper]

That looks like it should be diesel powered not electric :)

You better be careful and hide this beast from the Global Warming folks because that has got to leave a large carbon footprint :)

Very impressed with this build and cant wait to see how cold it pulls down when complete.

[SAE]

Wow, red it is... not orange indeed! :up:

[Rembulan]

OMG

To me its more like chemical factory than a CPU cooler

[Sam__]

That looks like it should be diesel powered not electric :)

+1 wheres the diesel tank??!! :D

insane build.

[clear cmos]

wanna see this unit running :rolleyes:

[SexyMF]

wanna see this unit running

I second that!

Anybody know if there is an update on any other forum?

[gosmeyer]

Still----I got nothing-NO one NO where can do this at this level of CPU cooling period that I know of, who ever has an IT -- M G I or ??

Is this going to White Sands? LOL ?

[Patrickclouds]

On the latest pics with the red semihermetic compressor you see that electronic and cables have been removed.

He is waiting for 5 frequency inverter.
Today we are going to get a big switch case.
So if everything is here he remakes the whole electronic that you can disconnect the switch case from the unit.

[clear cmos]

any updates from this monster? want to see some more pictures again :P

Are you working on this build too?
Is it a team of you guys building this for a company or whats the purpose.

[Patrickclouds]

we often build units together but this monster is his own unit :D
i support him sometimes when he´s building on this unit ;)


today the switch case has been dismounted and cleaned, so the next days it will get a beutiful color.
pics of the 1,20x1,20m switch case are on his cam.

[Foamy]

Lol this thing will cool every pc in germany and still keep idleing at -178°c :D

oh man, to be around for this monster's first day in the benchroom would be quite nice. Suckers gotta be loud with that many stages and that kinda power. I love it, though i think i liked the saftey yellow color more :)

Why is there a need for a frequency inverter?

Amazing wiring and case construction :O

[teyber]

Why is there a need for a frequency inverter?

Amazing wiring and case construction :O

Because the compressor is(are) a 3 phase compressor(s) that will be run on 1 phase perhaps

[plasmatique]

Which job you made:up:

Which is the budget of such realization

[[XC] gomeler]

Because the compressor is(are) a 3 phase compressor(s) that will be run on 1 phase perhaps

His inverters take in 3 phase and output 3 phase. I'd say he might use it for capacity control, just slow down or speed up the system to adjust for capacity.

[Riska]

Why is it the same pic you have posted multiple times?

[Ozzfest05]

This keeps blowing my mind.

[Rava6e]

I have no idea what kind of contraption you are building but if the government gets word I think they'll be picking it up.

instead of buying a TRUE he just builds this, i think he wants people to believe its just a CPU cooler. hehe sorry i just had to

never posted in one of these threads before but i just had to say this is some sick work, great metal work and all that, keep it up it looks great :-)

also out of curiosity, what is this "ln2 cooled SS" mentioned on page 6 or 7?

[Patrickclouds]

hi,

this is the ln2 coold singlestage :D

http://www.extremecooling.de/forum/singlestage/886-200a-c-club-ist-jetzt-offen.html

A singlestage which is filled with nitrogen. It condenses the nitrogen in LN2 from a dewar. The lowside is running in a vacuum so he get this nice numbers.

[Rava6e]

thanks
thats some pretty crazy stuff hehe, keep it up :-)

jeez so your using a vfd for each stage? i wonder if a computer will control the vfd's so you can adjust how much each compressor has to work or something

this project is nuts

What I love about XS is being able to watch incredible stuff done and the constant avidity to raise the bar. What makes me like this thread so much is that the part I dont like about XS ( the flaming ) is not seen here. My explanation is that there is such a level of expertise involved in here that we can only watch and some can ask ( I can only admire). Take into account that OP's English is not excellent (maybe it is but he does not care about it) and no one seems to care ( I dont, either :D:D:D). Why? Simply because we see passion, dedication and professionalism being depicted and kindness by providing updates and posting pics.

:up::up::up::up::up::up: to you man ( -EC-UnRockStar und Patrickclouds who seems to help a bunch and remains in a low profile) :up::up: . Take the time needed to do all the necessary math and calculus involved in there, and over everything else: ENJOY IT as much as we do.

Is it a dream? should I reset my computer!!? :help:

What are you trying to do here? Send Europe to the next ice age?:D

[-EC-UnRockStar]

no not Europe, sweden only :P :D

[ong]

From the Pic. we can see each compressor have 1 pressure transducer, l connect back to PLC and PLC send signal to SEW inverter for control each compressor speed.

what is the min and max of the comp speed (hz).?

[-EC-UnRockStar]

1st stage 30-60hz(70hz???)
2nd-4th 40-70hz(75hz?)
5th 30-70(80hz??)

[Duh]

True :)

But then again that always amazes me too:yepp: I am always so shocked at how wealthy so many people are.

Or maybe its just how poor I am lol

semi off topic:
I know you are saying this as a joke, but I am thankful ( I dont have much and I live in the arse of the world, most likely you cant even point it in the map, not for you being dumb, but my place being irrelevant) for what I have. Also notice that the US is a very gentle country ( you can protest about your conditions, although I cant tell how you are ,as much as you want, but in a general aspect, it provides many opportunities and it is the land of 2nd chances to many people).

In my case I had to work as a donkey for over a year for having a very budget laptop and I love being able to accomplish this and to be able to read the forums, help as much as possible for WCG and MJ12. Thankfully many guys in this forum have helped me a bunch in almost every aspect.

All I have to say is that I tend to watch more than I post as I admire what I see and I love what you guys do ( except when you fight like: AMD vs Intel and who can do better benchmarking)

What I am trying to say is: Unrockstar is building this monster with:

-Knowledge ( and years of studying)
-Being a handy and determined person
-Passion for what he does, otherwise he would have quit or would have spent all this truckload of Euros in something easier and with quicker results and with those who provide him more pleasure.
-$
-from a humble point of view
- a generous side, otherwise, he would have kept it secret until he succeeded.

My :up::up::up: to you Unrockstar. Do whatever you do with your project, you already have my and many others admiration. :clap::clap:

I kind of exceeded myself.. SHould be back to study :P. Keep punching (as olde George Foreman says and I love to say).

Auf wiedersehen or bye bye in English :)

Oh man can't await the first results. Is it possible to reach -200°C with this monster?

lol i smell a true blitzkrieg :D

[HitandRun]

HE HE! Them mad Germans! :clap:

[eXa]

ive seen alot of insane stuf.... but for this i have no words...

[cooling storm]

try to use heleum in the 5 stager.

[-EC-UnRockStar]

no i Will Use Argon in the Last Stage

[cooling storm]

why

[Riska]

Because it can handle the cold very well Argon is nearly the same as lN2

[-EC-UnRockStar]

i dont use Helium because i cant condesed the Helium in the last stage. same with N2

[cooling storm]

of cource :doh::am::brick::dammit:

[cooling storm]

someone shod make a 10 stager

[iNF3rN0]

you blew my mind.

[sdumper]

I know this is a PITA of a project and it can be annoying when your frustrated trying to solve a tuning issue but this is such a very cool project I have to ask hows it coming along are you getting the kinks sorted out? I am so completely blown away by the electrical that I cant even express it in words. It is just amazing....

[Patrickclouds]

we are working on the pt100 probes. it´s not easy to get them running with the sps.
tomorrow we give it another try.

[SoF]

you guys are just crazy :up:

[Duh]

you guys are just crazy :up:

I would love to be crazy if being crazy involves this knowledge and passion. Way to go. The world is watching and holding their breath. We ( at least I) dont care how much time you take to make this puppy achieve your aims.


:up::up::up::up::up:

[plasmatique]

You would have some news :)

[-EC-UnRockStar]

Sorry but at the moment i´ve no time to work on the 5stager.
i´ll hope that i find time to finish the eletric part on the cascade

stay tuned

[Duh]

we are :) take all the time you need :) :thumbsup:

[miahallen]

WOW...this project is just SO INSANE! Looks like you're getting closer to being done too!

When I first saw this project a few months ago, I thought hummm....too cold for i7 and not cold enough for PII...but you guys have a crystal ball and saw i9 coming didn't you :up:

[M.Beier]

Impressive build unrockstar!!!

3 things
1) The 15HP compressor, how much does such a beast cost?? A singlestage with such monster should easily hold 5 evaps at -70C @ 1100W load (i9+2x HD5970) :p:
2) Will that thing be ready for AOCM, and if so; will you get it transported to the event? :-)
3) LN2 fun always, especially after beers (cmon, we didnt hurt nobody or them tables ;) )

[FireDragon]

...i am just lost for words, it is just crazy that 1 person has built this (with some help from another), he must have been living breathing and eating cascade information for the last year lol, it is just INSANE great work and 2 thumbs up for the build quality it looks second 2 none!!

Dragon

PS. he must dream about the wiring diagrams on this thing, that is just crazy on the electronics end of things, U know your stuff Unrockstar, also how old r you if u don't mind? 23-27?

[[XC] gomeler]

Very nice, 5th stage is argon?

[-EC-UnRockStar]

yes its argon its hotgas :D

[[XC] gomeler]

Very much so :D If you wouldn't mind, what are your gases, pressures, and temps on each stage? I am investigating using R50/methane and I believe you are using it on your 4th stage? Really curious what condensing temps and pressures you are achieving.

[Tetrafluorometh]

I ment test on the video live link what ever it is thats not working

[Patrickclouds]

we´ve written down some numbers ;) maybe unrockstar will post them the next minutes ;)

[Tetrafluorometh]

I wana see video man! Numbers are nothing but seeing frost, fog, grown men excited and scared and the 5 stages boiling away and groaning i deman a video!

[Buckeye]

So it hit -160c on the Evap ?

[august123]

for sure, -167,8°C on evap of the last stage, when everything is working well it will be something like -180°C, and hold some nice loads :)

[[XC] gomeler]

Thanks for the numbers. The R50 stage with R14 condensing it should be much lower though, right? I was expecting around -120C condensing temp. Looking forward to seeing the results after you tune it.

[Patrickclouds]

in the second stage we had 1bar suction pressure. on idle and on load it was nearly the same. i don´t really know why. but we are going to replace the compressor with a larger one. so second stage compressor is going to replace the one in the third stage. we hope to get lower temps in the 2nd and 3rd stage.

Good luck it sounds like your making great progress.

What is your idle temp on the second and 3rd when the 4th and 5th arent running?

[Patrickclouds]

second stage idle was -83°C without third stage running.

but thats the only number i can give you ;)

[HeXploiT]

Fanatic!

I'll believe this is for a computer when I see the computer.

[Patrickclouds]

Do you not know the 3rd stage temp ;)

i only remember -115 on evaporator outlet. but that was with all stages running.
but in the r14 stage the orifice is too large. there is a 5 orifice in it. this will be chnaged with a 4.

stage 2 becomes a larger compressor and the compressor of the 2nd stage is going to replace the compressor in the 3rd stage. we hope too achieve some lower temps ;)

have a nice evening here it is 6:20pm only few hours left till midnight ;)

Thanks...im asking because im working on tuning a 3 stager right now and trying to find an ideal balance but my r14 3rd stage is a PITA to tune...

If 2nd gets too cold my pressure drops to much on the 3rd and if my 2nd is warmer like -80c then I cant seem to hit -130c so im trying to find a balance...

[eligray]

Well I've heard liquid oxygen can be quite dangerous, but...

If the evap can hit -183c without load, then if you just freeze a HSF to the evap, you will have LO2 drip from the HSF (and easily into a dewar for storage)

I have a bit of personal experience condensing LO2 out of the air... Just put some LN2 in a metal bowl and then hold the bowl up and look at it's bottom. Obviously there will be some frost, but the area around the LN2 looks wet, and also drips liquid oxygen.

If you have any fun things to do with liquid oxygen, it should be pretty easy to collect at -185c or below evap temps. Just be careful :)

EDIT:

Nun, ich habe gehört, flüssigem Sauerstoff kann sehr gefährlich sein, aber ...

Wenn die Verdampfungstemp treffen kann-183c ohne Last, dann, wenn Sie nur ein Einfrieren der HSF Verdampfungstemp, werden Sie LO2 tropft aus der HSF haben (und einfach in ein Dewar für die Lagerung)

Ich habe ein wenig persönliche Erfahrung kondensierend LO2 aus der Luft ... Einfach einige LN2 in einem Metallbehälter und halten Sie dann die Schale auf und sehe at it's unten. Natürlich wird es einige Frost, aber die Gegend um den LN2 sieht nass, und auch Tropfen flüssigen Sauerstoff.

Wenn Sie keinen Spaß Dinge, die mit flüssigem Sauerstoff zu tun haben, sollte es recht einfach zu sammeln, 185c oder unter Verdampfungstemp temps. Genau darauf achten :)

[[XC] gomeler]

Easier to just buy liquid oxygen, will be cheaper per liter than using that cascade to condense it from the air. Depending on which way you look at it, LOX and LN2 are waste products of each others production.

[eligray]

True, I guess it would be more suitable for single-test-tube type use, with burning cigarettes and such.

But more importantly, It'd just be downright cool to be able to condense LOX from air

[Tetrafluorometh]

LOX is BOOOOM very very very easy

[[XC] Lead Head]

LOX is BOOOOM very very very easy

That is only partially truck. LOX in itself is not flammable, and as long as you keep it in a non flammable container, there is really nothing to worry about. Except that it will oxidize many metal containers very quickly. Now if you drop a burning piece of wood into LOX, you are going to have issues.

i wait for R14 atm

i´ve lost some R14 round about 500-600g

[Tetrafluorometh]

Thats a costly mistake

[sdumper]

Thats a costly mistake

Very costly...at least in the US it is.

[SAE]

I think Germany is way more expensive, especially since we have 19% VAT. :(

[Tetrafluorometh]

UK it's not, not now we are back at 17.5%

[ceemic]

Sorry for OT:
What amount of $ You are talking?
Tnx.

Anyway, enormous project :)

[-EC-UnRockStar]

the R14 who lost costs round about 60-70€

i´ve ordert 500g now

[sdumper]

60-70 is not too bad but it adds up....

[-EC-UnRockStar]

the cascade costs a lot of time and money.

ive bought some parts for the PLC --> 350€ :D

he uses eev elektronic expansion valve
from danfoss they are called AKV

[cooling storm]

haha lol make porn

[sdumper]

he uses eev elektronic expansion valve
from danfoss they are called AKV

fully adjustable electronically to alter flow?

[Patrickclouds]

they work like solenoid valves but have an orifice included.
so they can only open ore close the massflow.

on the other hand there are controlled EEV by an engine that adjusts how wide the expansion valve should open or close, so you have a coninously massflow

Lol nice project ^^ This is what i call a cascae xD; and i thought my new SS was kindof big :p

[Duh]

the Cascade need 15kW with 400V ~22Amps

Dumb question: can you power it up with the utility grid ( considering you have the proper gear )? or do you need some type of generator?

[august123]

usual german homes have 3 phases at 63 Amps, smaller homes at leas 35 Amps, so it should be no problem. But don`t use the kitchen at the same time :D

Did you change to 4 compressors or do you have one on top?

Also how much did you pay for each of those compressors or did you get those from work?

[-EC-UnRockStar]

the compressor from 5th stage is on top.

i bought 3 from 4 those Bitzer compressor.

Costs :

1st : None
2nd :150 + 50€ Fuel
3rd : 230€ + 25€ Fuel
4th : 150€ +25€ fuel
5th from ebay : 15€ +13€ shipping

[jesperme]

That is scary!:eek::D

[sdumper]

Wow those prices are dirt cheap for those compressors!!!

[berkut]

I love the brute force approach :D

[RoadconeTuning]

i know nothing about this stuff but i can appreciate massive :banana::banana::banana::banana:

[Patrickclouds]

today we finished the 2nd and the 4th stage.
4th stage is filled with nitrogen and should be leak free. we´ll be watching it the next days.
on the 2nd stage we have leaking cylinder head gaskets which should be replaced when new ones arrive.
next is to finish the liquid line to the tev of the first stage for the oil cooler and install the condenser of the first stage.

i hope for another test run next weekend but this depends on how long it takes till the gaskets arrive.

[fatguy1992]

Woah this is one awesome project :up:

Sorry if already stated somewhere, but what gases are being used in each stage?

[Patrickclouds]

1st stage r404a
2nd stage r170 (ethane) or r1150 (ethylene)
3rd stage r14
4th stage r50 (methane)
5th stage r740 (argon)

[-EC-UnRockStar]

5 stage Nitrogen? :D
i will hope the 4th stage runs good with the bitzer

[nigelke]

o may that's insane :D

I love it :D

[Patrickclouds]

today we had a new test run with the new compressors.

in the 3rd stage we need more refrigerant or had to replace the orifice with a larger one, because superheat becomes tooooooooo big.

here are some pics from today with some descriptions:

the 2nd stage becomes too cold on the compressor. the suction connector had -80°C. bitzer recommended not to go below -65°C because it can cause damage on the cast iron.

[Patrickclouds]

i don´t like the digimon and prefere the 4 way m4-3 deluxe or super snap on.
i wouldn´t buy a 2 way manifold.
btw, the digimon was absolutely new :D we had to unpack the battery first.

for superheat or subcooling i use this pdf with many refrigerations:
http://www.extremecooling.de/forum/attachment.php?attachmentid=6669&d=1252345967

or use coolpack if you have computer access while building the units.

[nigelke]

massive dude :D

i hate the Digimon :D

but i love the new Testo

I agree, the Testo 560 digital refrigeration manifold is a very nice unit. I had a chance to play around with one on my SS (Dad borrowed it from work).

[FatAlbert]

will we ever see this working on cpu ? ;)

[august123]

4 weeks to go :D maybe in Minfeld, Germany the monster will meet a cpu...

[sdumper]

I forgot to ask earlier but how are you cooling those compressors?

[tool_462]

I forgot to ask earlier but how are you cooling those compressors?

Probably with a 3 stage cascade on each one, and those are cooled by single stages that are water cooled. I'm just guessing though, based on the xtreme factor of the 5 stager :p:

[-EC-UnRockStar]

the compressors will be cooled by the Suction Gas .

Crankcase temperature are round about 40°C

No additional fans? Did you position the condenser fans to blow across the compressors some?

[Patrickclouds]

yes.
but last run i didnt look after the compressors temperatures.
i think they are in a normal range. except the rotary in the last stage :D

[Fhqwhgads6680]

Dear god...

Alot has changed since I've been around this neck of the woods...

Congrats on an absolutely amazing build!!! I am at a loss for words....

[-EC-UnRockStar]

Yes .

but this isn´t necessary

[teyber]

edit: oops misunderstood my bad

[sdumper]

sheesh sorry if i misunderstood but hes just giving you a compliment. if you don't want compliments why post anything on a forum

I think he was responding to me :)
I asked him if he was using the fan output from the condensers to air cool the compressors. The suction cooling is apparently enough for these compressors since floodback doesnt appear to be a concern.

[Patrickclouds]

that was the answer to sdumpers posting ;)

you can decide on those bitzer compressors if you want the suction gas to flow over the winding or not. he decided that it shouldn´t go over the winding.
so the superheat should be a bit smaller, but i think you cannot put the engine heat completely out of the cycle.
so normaly in such a case you should use cylinder head fans but i think we don´t need them.

[[XC] gomeler]

Ahh, that is very interesting. So the windings are cooled solely by the compressor oil? Very interesting. Maybe someday I'll have a chance to play with some gigantic compressors :up:

What are you guys currently working on? Tuning the stages or still sizing compressors?

[kayl]

fork they are some nice compressors and temps ;)

[Patrickclouds]

next step is to make another testrun. write all temps and pressures down and find out what problems we have in the different stages.

[imersa]

Love the work here!
I am about to invest on my second single stage.
Not quite as impressive as this!
Keep up the madness!

[OverShocked]

I cant wait to see the actually working... when you first turn on the 5th stage before tuning, make sure you have a long cap tube so we can see you make some ln2. That would be so cool. :D

[sdumper]

Man I feel your pain :(
Working with multiple compressors/Temperaturs/Gases can be a real pain. You guys are doing a great job!!

What size compressors are used for each stage?

[Patrickclouds]

liquid oxygen would also be very nice ;)

but first we have to chnage the orifice of the first stage and remove the solenoid valve on the fourth stage for hd bypass into the plate. that opens a bit if it becomes to cold so that the suction pressure ruses to 2-3bar :D

first stage 32m³/h
second stage 22m³/h
third stage 22m³/h
fourth stage 12m³/h
fifth stage 5,7m³/h
but all are tunable by in/de-creasing the frequency

According to post#1:


Compressors are :

1 Maneurop NTZ 136 22m³/h
2 Maneurop MTZ56 16m³/h
3 Maneurop MTZ44 13m³/h
4 Maneurop MTZ40 11m³/h
5 Lunite Rotary 4m³/h

ROFL :rofl:
you aren´t planning to switch to bigger ones? :D

Any issues with the temps on the first stage?

[-EC-UnRockStar]

-39°C under load

[sdumper]

-39°C under load

all 5 stages running? Also what gas are you using in your second stage. Just curious...

[Patrickclouds]

but first stage orifice is too small. with all stages running the temp rises to -5°C on plate hx outlet.

second stage is a mixture with ethane and some ethene because ethane was empty and we need more refrigerant ;)

[Duh]

what temps are you expecting with a VERY strained hexacore? Also: would you be able to have it dual headed ? I can't imagine this (http://img12.imageshack.us/i/sp1m4500.jpg)under some xtreme cooling. it's a dual socket beauty (http://www.xtremesystems.org/forums/showthread.php?t=246135)

congratz guys keep it up

[-EC-UnRockStar]

i´ve orderd a new orifice for the 1st Stage today =).

[sdumper]

What temps are you expecting out of the ethane on the second?

[-EC-UnRockStar]

i dont understand your Question :D

t0 -85°C
t0h -77°C
tc ~-30°C
tv1 =-70°C
tv2 ~80°C
p0 1 barg
pc 17barg

Sorry under load on the outlet of the 1st HX feeding to the second HX what loaded temps are you seeing with the r170/r1150 blend.

[-EC-UnRockStar]

Do you mean the liquid temperature from stage 2 called tcu??(-28°C)

sry my englisch are very bad :D

Yes thanks

[-EC-UnRockStar]

I have remove the EEV Bypass Valve in the 4th Stage and switched the orifice from 2 to 3.

[miahallen]

Any updates guys? Really enjoying the show here :toast:

[-EC-UnRockStar]

i had no time the last 2 weeks to building on the 5 Stage.

i think , i start a new run at this weekend

[okydoke]

Been watching this thread for what seems like years now, loving your work!

I know your just kidding around but folks need to realise what a PITA it is getting the gas pressures and compressors working just right.

This is not like building a 2 stage cascade it is much more complex and if you check out the electric work you will quickly get lost...

Anyway hes made some great progress and my hats off to him and the guys working with him :up:

i know right, whats even funnier is this thread is been here longer than stangracin3 haha

[fl0w3n]

Das ist so beeindruckend, dass ich nicht einmal weiß, wo man mit einer Beschreibung, es zu starten. Ich verbrachte zwei Tage lang Lesen dieses Threads, mit wenig Schlaf dazwischen natürlich und las fast jeden Beitrag der zwanzig Seiten. Ich wünschte, ich hätte das Engagement und Fachwissen haben Sie, auch wenn es in jeder Kategorie der Arbeit war, als ich einundzwanzig Jahre alt bin, wie gut, aber ich glaube, ich habe nicht annähernd so viel, wie Sie gerade in diesem Build getan haben vollbracht! Herzlichen Glückwunsch und danke Ihnen für mich inspiriert.

Vielleicht können Sie mir einige Hinweise zur Verbesserung meiner einstufigen Phase Einheit :D

Ich kann nicht warten, bis die Ergebnisse der mit diesem über eine tatsächliche CPU zu sehen.

Auch schrecklich leid, wenn dies geschrieben wird, meine Muttersprache ist Englisch und ich einen Übersetzer zu diesem Typ :p

[stangracin3]

i know right, whats even funnier is this thread is been here longer than stangracin3 haha

well i had another account but i forgot the Password, and the stupid email server was down for about 2 years, so i was SoL,

stangracin2 was my other account, so yes ive been here for longer.

[miahallen]

OK...I see you took this beast to the AF event....we want to know the results!!! :D Please! :up:

[august123]

cascade was on aocm in minfeld, big action to get it from the truck to benching hall, but with pure muscle power it was possilbe! I think we will get some pictures of that in the next few days.
One wheel of the cascade was killed during that, we had to replace it with a car jack :D
Unfortunaly, the run wasn`t very successful, the 5th compressor had another winding fail after some minutes running, but we have seen something like -140°C on thermometer. There are some videos of that too, just wait some days :)

And i hope unrockstar himself will give you details soon!

[Snowman89]

Any update? Where did the results go?

[sdumper]

[wdrzal]

Any update? Where did the results go?

Some people have to work for a living.....cut him a break:yepp:.....And when there is a problem the buck always stops at the top. I have great employees but some times I need to show up to troubleshoot............It's really a 24/7 job because anything you ever designed/installed can break at any time. Always something to be thinking about.

I'm sure updates will be posted as progress is made. :up:

Im still in awe of the electrical and pipe work it makes my head spin...

[M.Beier]

All I can say is; This is the sickest piece of machinery I have ever seen, very impressive work by unrockstar, and think it rocks (yes; even after it powered off my benchrig during WIn7 install, hah)
