Yeah, nice article. If you have questions on restoring screws & certain pieces, you can borrow technology from auto restorers. A good place to start is with the Eastwood Catalog.

If I was going into the business or restoring vacs, I'd want all the tools & methods to do so. Personally, I think it would be a tough business to sustain you. You'd need a slick website and be on eBay. Also, you'd need to have a good warranty and be obliged to deal with nutters. People by and large that collect vacs are looking for deals and/or they do the work themselves. There's room for those that want to pay for full restorations, but I don't think it's a huge market yet.

Well, if you call that a fault....I'm guilty as well. I'm much more interested in how things work and making them work perfectly....then actually using them all the time. I haved some very nice 35mm cameras and lenses...enough that you'd think I was quite the photographer from the past.  Truth is I marvel at how they all work and function more than taking pictures. 

Like most people here, I have more vacs than I can 'practically' use. I have to force myself to switch models/brands.  During this house move it was nice to have different vacs at the two locations, but was really the only time 'necessary' to have more than one vac.

The natural progression then would be to fix vacs for other people....lol! I have restored about a dozen Diamond J's and given them to family & friends to great effect.
