Great Work bazx !!!! I Applaud you on your safety measures :clap:

Every cascade Must have there components installed to operate safely.

Don't forget as each of you design and build your own rigs.you are actually build prototypes or experimental models,so install a pressure limit control,pressure gauge and most important,if things start to go really wrong a PRESSURE RELIEF VALVE.


Work Safe: Walt

Ps: To Mods with bazx's permission This picture should be added to the stickies under cascades as minimum safety requirements. Be sure that the components names are also there.

good luck bazx
very nice insulation of hx
A very very good idea. I'll use it next time :rolleyes:
Are you going to use capillary tube on the 2nd stage? What length?

yes there will be cap on the 2nd stage 0.031"@2.6m

i am pleased with the hx box i spent some time thinking about it

i see brazed plate HX more and more, im starting to like them :D, maybe ill give them a try in a future project!

Very nice cascade and parts!

Just make sure you don't puit the oil sep upside down like i see on the pics :)

Have fun building!:D

I'm Glad to hear my rants are getting thru to some. (the smart ones)

Building a safe unit not only eases your mind but will give you a sense of PRIDE "you did it right" :toast:

Work Safe: Walt

got a bit more done today

all the mounting brackets made up so all the parts are fixed now

and most of the 1st stage

Very Nice HX insulation , and clean setup Oo looking forward 4 complete system . :)

I am really looking forward to seeing the finished artical - The case and everything looks superb baz mate, a real work of art.

Wheels for the base would set it off a treat (probs 5 required lol)

Mav

this is gonna be a nice cascade bazx.
i like the enclosure on the plate hX.:toast:

Thanks guys

Did a bit more today, it is getting real tight in here
I have tried to keep most of the hot, warm and UN insulated pipe work down
In the middle to bottom of the unit as I hope to have the most air flow there when finished

Just got the shut down switch to go in, the suction returns pipe work
And controller

next week end i hope

This baby is so clean and well done, you get a "oO0o..."! :D

nice work and it's really clean, gz dude for building that insane cascade

Will be interesting to see its performance :) .

i think it will perform about the same as cascade 2 but for me with this unit
it is about getting it all in a box

here is the mount i will use

Thought you'd sold up mate? - Tho spose you could use it on your lappy, that'd be a great project.

Don't get em started Pete FFS (it's an ideal opportunity for me to get my own back here and yet I find myself taking the higher ground) :stick: :fact: :stop:

@ Highlander - nearly wet meself reading that for all the right reasons:D


@ Baz - sorry for off-topic-ness, back on topic - gotta be one of the most beautiful cascades, ever - I can see you are using a Vapo mount - what Evap is it?

This is not a vapo mount, its from that company called Cooler express. The same guys who made that 3 head unit that was on here a while back.

BTW nice cascade Baz

I have a new rig now!

Mav belive you havent yours yet ether!!! I wont be getting anyhting of mione for at leats 6 weeks now and now i really can not be bothered...my trust has fallen big time!

I've got a few new contacts which do stuff in a week to two weeks and there work is far better sadly!

So were on a par Mav for the time being! But in all honestly does it really matter?

If i want a cascaade i can have one, SS, chileld water, water or std air! Ently up too me

Getting close now

Just gassed up the first stage with R507 and have the second stage leak testing
With some nitrogen

Next job up is the evap and line set and gas second stage with R23

Nice work here my friend, keep on goin`, want to see nice loaded temps !

thanks luke

soon i hope:)

fixed the hx temps probe to the hx today made up the evap line set

just have to braze it up and load test

That will be great cascade bazx, we all want to see some good temps ;)

Thanks, LittleDevil

Bazx m8,i truly like your style and dedication,awesome build.I just know you will make this more than most could ever hope for in a cascade.It will be powerful,attractive,compact,reliable and most importantly,safe.If i ever get to finish mine,i will look to you for inspiration.

I'm also taking notes for my next cascade this one is just tooo clean :toast:

@ thicky and fatty thanks guys


well got my first temps now hx is holding very well and i am very pleased with it
sits around -43

got the evap to -97 unloaded so still some work to be done there

i am sure it is just cap length it should have been 2.6m of 0.031 but i must have left it longer

fix that tomorrow now:D

Insulate suction, you will gain some extra *C ;)

Is that r23 or r1150? Did you try loaded temps, if not try it for load first than you change captube. When you will issulate all tubes you will see -100°c for sure.On your old cascade you used costum HX, where do you have better temps, here onPlate HX or on Custom HX?

regards

hehe you are right luke

@ld r23 for this one but will try r1150 next week

the plate hx is around the same as costom hx but 1/3 the size and it pulls down much faster

Man what a beauty - great work - excellent layout and attenton to detail Baz mate - early indicators are its a performer too.

Load temps is what its all about though surely (he says not really understanding it all).

I get all in a tiz about all the gases that are available to use - looking forward to the results Baz mate.

Txv probe should be positioned at 10:30 or 1:30 on tube.

Txv will respond better if probe and tube are insulated.

VERY CLEAN build :D

did most of the insulation

http://www.benchtec.co.uk/1/cascade3...6/DSC00347.jpg

http://www.benchtec.co.uk/1/cascade3...6/DSC00345.jpg

took 5cm off the cap

http://www.benchtec.co.uk/1/cascade3...6/DSC00337.jpg

http://www.benchtec.co.uk/1/cascade3...6/DSC00342.jpg

Ohh great looking, did you try it on load, for what tubing/size is that sleeving?

thanks

i think thats as good as i will get with r23

just hooked it up for some load testing and manged to pull the cpu out the socket

i am going to get a load tester now:D

http://www.benchtec.co.uk/1/cascade3...6/DSC00331.jpg

Amazing dude. Look forward to full final pics of it all enclosed in the case! If ya thinking what i am still then yes to your answer!!

Looks awesome Baz :D!

This Is Ownage :d

forgot to post the evap work

nice, like the way ya did the evap:toast:
how thick is the base of that evap.
Is it hard to brase without getting any solder in the ring part?

MMmMmmmMmm... i like the brazing job :)

with the mount i am using i have to get the cap as close to the suction return as pos

as for the brazing it depends how long the brazing rod is

ie for fine work i use a shorter length as it will shake less well some times:D

i will check with ld for the base thickness

@jin thanks

That brazed evap is excellent. What did you use to clean it?

I see on the picture of your purging setup, you have the N2 bottle connected to the capillary tube which is fed into the bottom of the evap. But what is the other part of capillary tube there for?

Holding the evap in place I wonder?

Could be, but I would think that captube wouldn't be strong enough for doing that. I may be wrong though.

It doesnt look like captube to me though. Maybe to just push some more purging gas into the evap?

Yea possibly :) .

I want that Oxy-Acetylene brazing setup hehe :D . I used one last week to braze my first unit up, and they just put out some insane heat!
Only problem is cost really, I was told the portapaks are really expensive.

the other wire is just to balance the evap and hold the cap tube out of the way
while brazing

Oxy-Acetylene is by far the best for this job but as others have shown not essential

i use 3x different nozzles for brazing these are BOC sizes

number 1 for fine work and most of the pipes

number 3 was used to braze up the tes2 1/2 to the hx

number 10 for the evap 3 could also have done this but not as quick

if you were using Oxy-Acetylene for the first time i would say use the number 3 for the evap

Looks crazy nice :)
