"Teybers Rotary SS"

[teyber]

hello all! finally getting to a stage in this process, where i am starting to work. I still have so many things to buy and make, but i will start. This thread is pre-mature, but if you have followed any of my other work threads you will know i post lots of pictures. I am still waiting on condensers from nol and a mill for evaps, and some other odd-and end things.


What you see here is:
robinair 15600 vacuum pump(+oil)
30lb recovery tank
recovery unit(+filter)
uei dt-200 thermometer
15% brazing rods
2 core removers
1 core removal
spring benders
bending tool
2 pipe cutters
schrader valves
ball valve
cap tube cutter
anti-blowback valves
and several other things.

What you see here is 60 cubic feet of nitrogen with a nice regulator. In future i will invest in a flowmeter regulator in addition, but this is more then fine for purging now. this should be great for pressure/leak testing

50 feet of .25" refrigeration tubing, 10 feet of .031" cap tube, and 12 feet of .04" cap tube. (yes, very un-restrictive )


here is a mapp torch, oxy/mapp torch, oxy/mapp/propane bottles, flux, brazign rods, helmet and gloves. i actually have a oxygen acetylene kit on the way which will be very fun!


and last but not least, 2 compressors i have here, and desup... The desuperheater is made of about 60" of .25" tubing. Its crooked *cough* on purpose to increase surface area? ill straiten it out. I was having a hard time not getting the bending to crip while bending it around some 2.25" aluminum solid stock i had, so i had to do it by eye. the two compressors are a 5k btu rechi compressor, and a 5.5k btu LG hero compressor. The rechi is much smaller and is brand new, i will be using it(most likely) on this build. The LG is a stronger compressor, but it lost a lot of un-measured oil when i had my little r-22 accident and it think it would be a very discouraging first build to use it. Once i get the condensers i will be starting this build.

P.S. total price in tools so far is 1750$ and still need to get my 608 license, refrigerant, and other small things. Variac is on way, load tester is almost done. Will post pics of that when done.

P.P.S. Might swap compressor out to a matsu$hita 1/2hp rotary, or might incorporate one of those into another build.

Regards

You already forgot 1 important thing in your second picture, mounting your nitrogen tank to the wall with a big chain.

Nice set of tools

thanks!
Yes, i am going to lowes tonight and will be picking up a small segment of chain. I completely cleaned out my garage over the summer, (like 100% makeover...) and many things got thrown out that seem like junk, but now im regretting it... chain being one of the many things

peace

Nitrogen reg looks like it has a flare output, so why the clear tube? Just hook your charging hose up!

Yes it is. I am mostly just purging and whatnot now. I have the tubing on their becuase 1) i have extra watercooling tubing, 2) its easy to attach to a couplng and attach other tubing to this small diameter for purging... What i last did with this was fill the desup full of nitrogen to keep insides from oxidizing. How long do these bottles last? a huge amount of nitrogen was coming out, or so it sounds. Nothing out of the ordinary or wrong, but i just can't imagine it last very long... then again, it is 3/4k psi

Peace

it will last for months if you just purge a couple of units/week. it's the pressuretesting that really consume volumes of nitrogen.

[killermiller]

Pressure testing will make it go very fast, especially if you have a leak. Nice looking vac you have there.

[Sneil]

Nice to see this up Teyb! You'll make a great phase builder, glad i was able to help out although i still have a long overdue pm i have to get back to over at eoc.

Sweet... problem for purging is i can't even measure the psi coming out... As the low side has no pressure, its just being pushed through a open pipe... I will invest in a flowmeter regulator sometime soon, but i a little overwhelmed with what i have here

Thanks! Luckily its only 15$ for me to fill this 60cuft baby up and 30$ for argon

Thank you! your the one who inspired me. No worries on the PM, i tend to delay PM's sometimes... (unless im asking a question )

Stupid question guys, What keeps the compressor's oil from igniting while brazing on high/low side connections? And sense running nitrogen through the compressor wouldn't fill the intire compressor inert (the pole/offset shaft part of the rotary), wouldn't you get nasty oxidation it lots of parts of the compressor?

Peace. im still thinking of building a case for this... I don't think i will. Im not sure what i will do with this unit. its a total crapshoot, being my first build and using homemade evap, but im hoping for -20c/-15c while loaded with either r402a or r507a... We will see though.

You have collected really great tools, teyber. I wish you a lot of success!

You better not get compressor shell that hot to ignite oil. If it ever did, you have acidic oil in loop not to mention the fume is toxic. Wonder if it is possible to ignite oil inside compressor by heating it up so much.... (I mean... it's pretty damned big mass....)

thank you very much! i will probably need all the luck i can get

Yeah, i was really wondering the same thing... or even if not hot enough to ignite, im sure its possible to overheat the thing and ruin it. I think i will invest in some 45% brazing rods sometime, well i need to for suction but i was thinking for compressor ports so i can just apply heat pull out and apply the 45%...

[boshuter]

Good luck on the build..... you sure are getting started right

As far as getting the compressor oil too hot from brazing on suction and discharge lines....... forget it You would have to try very hard to get the compressor hot enough to hurt anything from brazing on those tubes, when the heat reaches the compressor shell it just radiates out from there, it would be extremely hard to put that much heat into the compressor just from brazing on tubing.

thanks I heard also, was it you who said it? but in rockdude's thread to wrap the compressor in a damp towel... I will try that.

i have a couple more pics for you guys.


First, i fixed the nitrogen tank

second, here is where i was on evap untill my lathe died

There is my in-process load tester. I think im going to re-lap it and change insulation. need to add a grounding screw and solder in my thermal cutoff/thermal fuse. Also note that huge hunk of copper its crying for a mill... (evaps)

there is the front of my JB 4 valve manifold. This thing is friggin awsome


the rear. You screw in the un-used ends of the hoses here

Regards! and happy holidays!

p.s. sorry for blurry nitrogen pic...

[Stewie007]

You got all those charging hoses, now why don't you use one for your nitrogen? Less chance of it blowing off ^_^

[rocket733]

Looking at the pictures of your evap in progress it looks like you're trying to take too much material off it each pass. I don't know if you've picked up a book on basic machining yet (I've read this and it was useful but not complete), but it could help your finish. The same principal applies to the milling machine when you get yours. Anyways looking good, looks like you're all set

Definatly, I thought tubing was easier for purging... as the desup isn't threaded 1/4" sae. Definatly will be using my manifold for leak testing...

Really? im new to machining so i want all the advice i can get. I was taking of .02" or so per pass, was going at 520-580rpm's. The finish is terrible because i was in the middle of taking metal off when i see a large pop, besides the fuse, and it doesn't come back on But i definatly know how to get a better finish. Thanks for the book link

that's some NICE equipment you have there, how much did that cost you? I'm a year younger than you and I can't afford half that!

[teyber]

about 1,800$ not including refrigerant, 608 license, flowmeter regulator, 45% brazing rods, and other stuff

you young dratsab(read backwards) i am older then you therefore i am dominant jk. im about 2 weeks into my 16th birthday. Stay fresh

[LukeXE]

Wow, nice stuff ya got there

[teyber]

well, my variable transformer just came! sawheeet!


It has a distinctive smell that doesn't smell healthy... and has "made in china" all over it. i bet its loaded with led had to block something out of the second picture, you weren't supposed to see it lol. Its a 5 amp -130v variable transformer. 5a will give me lots of headway for say a waterchiller load tester. But i really want to tune this baby to perfection, so im not skimping on load testing.

Regards! merry x-mas eve.

I have an imperial 4 valve and feel like I wasted my money on a my 2 valve.

No you haven't. I use my 2 valve for dedicated nitrogen service
