Pullstart 59,649 #1 Posted October 24, 2021 @ebinmaine will appreciate this one I’m sure! We stopped by a clean out today in a town about 40 minutes from home. A guy’s father recently had a crippling stroke and his mother needs to sell things from the barn to pay for the nursing home. It was kind of like an American Pickers episode… we were climbing through knick knacks and whatnots just looking. I asked if he had any garden tractor or small engine stuff and I was led to a barn full of mostly concrete tools. Found this K91 powered air compressor. It has a clutch on the engine PTO shaft and there’s an air switch that pushes the governor back to idle when it’s full. No idea if it works, but it seems like it was worth it. 6 6 Share this post Link to post Share on other sites

Maxwell-8 4,270 #5 Posted October 24, 2021 In the days before batterypowered tools, this must have been golden Even now we often wished, we had compressed air in places with no electricity near by. That clutch design, would be cool way to make a aircompressor on a Wheel Horse, something that is on my "bucket list" 3 Share this post Link to post Share on other sites

Bill D 1,599 #9 Posted October 24, 2021 Nice. Who makes the compressor pump? Try to get a look in the tank for rust. Old air tanks can be very dangerous. 1 Share this post Link to post Share on other sites
Bill D 1,599 #10 Posted October 26, 2021 (edited) That looks like a compressor pump @Pullstart. Who makes it? It has valves that can be serviced without removing the head. Edited October 26, 2021 by Bill D Share this post Link to post Share on other sites

I’ll get it unloaded and inspect further. How should I inspect the tanks? They don’t appear to have rust on the outside, but I know they accumulate condensation inside.

Pump it up with as high a pressure as your shop air compressor will produce and see what happens. 1 1 Share this post Link to post Share on other sites

Pump it up with as high a pressure as your shop air compressor will produce and see what happens. Water heater tanks are rated at 150 psi working pressure, but they must certify at 300 psi and hold. I know air is much more volatile than water when it blows and doesn’t take near as much pressure to make a dangerous situation. I have a good hundred and fifty feet or so of hose… great idea! 1 Share this post Link to post Share on other sites
R Scheer 499 #14 Posted October 27, 2021 Mostly fill the tank with water, then pressurize it to as high as you can get it. If it does go bang, at least it won't be near as dangerous. 1 Share this post Link to post Share on other sites
