When I first got start, I jumped the gun and bought a small air compressor that I found on sale. Alas, at the time I had not done enough research and to my dismay the pump is a constant pressure pump and doesn't allow for PSI adjustment. I think the manual states 40-45 psi. Now looking through the archives at the PSI ranges that George and others have posted through the years, I am looking to "upgrade" to another compressor. I am looking at a couple from Harbor Freight (1/5 and a1/6 HP) with a max PSI of 58 but a constant pressure listing of 0-40 PSI and a 0.5 CFM at 20 PSI. I have found some at different stores that have a far greater PSI range, but I don't know if I need to spend the extra money for that range for what I will be doing. My question is, does this PSI range on the compressors listed above severely limit future areas of taxidermy finish work (big game/fresh-water fish)? Looking through the archives, I know a few have posted using around 30 psi and 10-15 for fine detail and a few list in the 50s, but I don't have a lot of experience to know what I would need for a max higher psi range. I don't mind buying elsewhere/better product, but I also don't want to spend frivolously as I am only doing this as a personal hobby while I am still in the military. Any sage advice/suggestions would be greatly appreciated.
