Thanks guys. I tried the website, but it looks like all information is now for sale and not free. I get it, he has a site to run and that aint free. If I purchase a PW, I'd happily contribute to his site. Most of these units have a manual, or a copy of one.
Tominboise, the Hydraulic system is a Leeson and I believe it was manufactured for this purpose, so I doubt it's a homebrew. It just looked a bit of a mess, of course, his entire basement is a bit of a mess! Fair point about being leery of inheriting a mess. I'd have to see the press run reliably.
DJB, the inability to "go back" is the main reason he doesn't care for the PW units he has. It can be hard to teach an old dog and he's set in his ways. He will marvel at new tech, etc., but in the end, he's a simple man. Truth is, by attending so many auctions, etc., he has more than enough live rounds to last two lifetimes. I just can't believe the amount he has accumulated. He's that rare bird that not only acquires, collects, hoards, but he also shoots and hunts, regularly. Most obsess with one or the other.
