I've begun making my evap and man is it ever easy to braze the silfos flows like water :D! Ill post some pics tonight but i can't finish it untill monday since i don't have the base yet.
O and BTW im going with 120"(10 feet) of cap tubing.
Heres some pics of the evap i've started to build. This is the outer shell that u see here. I got a good strong braze on the suction line as u can see the silfos on the outside and inside. Instead of using a T for the cap tube to come out of the suction line i just drilled a small hole in the side and just pushed the cap tubing through there (I just think it looks nicer than using a T).
R23 very good 2nd stage refridgerent.
If you don't have a cap tube cutter just take a small 3 corner file and file a groove completly around the tube, then "snap" it there . You should have a smooth end with the full internial diameter visable.
This is especially critical at the entrance so turbulance is not created and you have a good liquid seal
That one looks like you cut it with a ax.
I use a boxcutter blade and make a groove in it than i bend it sharply to brake it off.Quote:

I did a fast comparision of a 0.031" and a Q-tip and the 0.031 is still smaller. I think you'll need a LOT of this cap tube to be able to achive right temps.
Edit, ermm well he showed it to me on webcam it looks like a 0.031 and lower. It's smaller than how it looks on the pic :slapass:
cap tube measuring tool or you can use a caliper with dial indicator or micrometer.
U got a bigger pic of that thing i can't make it out?Quote:

UPDATE!!
I finished building my evap today. The worst possibile thing happened while i was putting it together the cap tube had a block in the section that was in the evap. In an attempt to free the block i put pressure in the cap tube up to 400psi with no luck :(. Next i tried reheating the evap so its red and while doing that i have about 40psi in the cap tube hoping whatever was blocking it to melt and be forced out the end....that didn't work so the last thing i tried was to keep it red hot and try to pull the cap tube out of the evap. When i tried this the cap tube broke off right at the base of the evap so with little else i could do i drilled another hole through all the end caps right next to the orignal captube and brazed it in place this time there was no block :D and than i finally brazed the outer cover in place. I still have to sand the bottom and grind the bottom plate down to size.
One last pic.
I don't think the base is thick enough...also I hope you're going to clean the inside of the evap since you didn't used an inert gas?
Pipes and all that are not that bad without inert gas, but evap is not thinkable...
And I doubt your base is thick enough has crash diner said...
Well its not like theres anything i can do about it.Quote:

I hope you use a pressure releif valve!!!
Whats that have to do with cheaning the evap? or the base being too thin?Quote:

Thats what filter driers are for. Im sure u know of such a device? :D :slap:Quote:

Well excuse me for not doing everything UR way! Have u ever thought that i might not have a propane stove.Quote:
