I've proceeded to begin my two stage co2 cascade, I'm going to be using a 1/4hp tecumseh compressor for the low stage, and have already made an oil separator very similar to the one pc ice outlined in his three stage thread (I used 1 & 1/8" pipe x 12" with copper wool inside). I was originally planning to use captube + a packless valve to return the oil since I dont have a proper oil float, but since the valve costs $40 I was hoping to use captube only.
What length of captube do I need for oil return? I dont know the quantity of oil in the compressor but I can measure it if needed.
One more question; I've been using stay-brite 8 solder quite a bit lately as I've found that it doesnt char the pipes black with oxidization. It's pretty expensive for the quantity, would it be safe to use it on only the high stress joints and use 60/40 or 50/50 tin/lead solder on the other (non vibration stressed) joints? I braze most of my joints with 15% silfoss but there are occasions when the heat isint't appealing to the surrounding area and surfaces.
