Thanks guys
@ tanguintel
You´re right. My oxygen was empty and I had to shorten the capillary tube so I took the unit to the company where Unrockstar works and asked his boss if I can use the brazing tool.
beautifully done patrick
a pleasure to look at
1. The first rule of Bench Club is, you do not talk about Bench Club
2. The second rule of Bench Club is, you do not talk about Bench Club
3. If someone says stop, goes limp, taps out, the the benching is over
4. No bummers in the batcave, apart from unkie dave
5. One Bench at a time
6. No air, no water
7. Benching will go on as long as they have to
8. If this is your first night at Bench Club, you have to Bench
thats an awesome looking unit man
keep building it
Looks Real Nice Can't Wait To See Some Numbers
Really decent unit
Very nice, Well done
I would have replied sooner but the compression explosion device in my motion traction system needed to be replenished with distillation fractionation of fossilisation extraction....

Why You've mounted condensor and fans in such, bit non standart way ?
Unit looks very good

this mounting method reduces the high pressure. i´ve tested that on a small condenser in a water chiller, so i did it the same way on this unit.
i think that pushing / blowing the air through the condenser fins pushes the hot air better out of the condenser than the sucking mounting.
You are right, you create positive presure on the condenser by pushing air thru, and negative by sucking. Offcourse the first is the best.
Isn't the desuperheater a litle too tight?
The insulation is lovely
it´s not a desuperheater it´s more a vibration damper.
I think the condenser is big enough.
I know that we misuse the desuperheater word around here, I was pointing out that the coils are so tight togheter
wow nice work bro
Great
