We did a T-bird using a larger plastic tubb filled with ice and about 30 feet of 1/2 inch copper tubbing. You still have to have a water seperator at the end of it. But the rube goldburg dryer worked for a one time shot. The tubing is emersed in the ice-water mix (about 70-90 lbs.). The seperator worked great in removing the water with a constant blowdown removing the water.
If you are looking for a permant fix go looking for a regular air dryer. Used ones can be had off of ebay. Good luck TF
