Surely tool of the month.

Been there, done that. That's exactly the arrangement (sans auto tire) that I used in high school to pump blood on the perfusion machine I built for a science project.

But Marv; without Facebook? I shudder to think creativity was possible without social media. And sharing knowledge, what's this World coming too?Quote:

It may look strange but try inflation by a car tire with one of those bycycle pumps and that looks just the nuts. It literally takes forever
As an aside I just left Cabin Fever and some of the mechanisms modeled there, many patented, just blows ones mind. I’ve gone every year for at least five years now and always see something new. Today it was a way to automate an old fashion well pump. In this case a 1917 patent pump, that is just a slightly more refined Rube Goodberg machine.
It can be pretty amazing to see some of these inventions.
Wizard69 if you think a car tire takes forever try having a flat in the middle of a field on the rear tire of a frame tractor a mile from the barn. You don't dare drive it on a flat back to the barn so when your 12 years old the only thing you can think of is to walk home get the hand pump use your pocket knife to cut a tapered wooden plug to plug the hole with then spend half an hour pumping the tire up enough to finish the days work.
the guy's innovative compressor is really neat.
I don't think he's trying to inflate the tire. He's simply using the tire as a reservoir tank to even out the pressure fluctuations from the pump so he has a nice constant airflow at the paint gun. The tire serves the same purpose as the capacitor on the output of the rectifier in a direct current power supply.Quote:

I cut off a branch on the way home to carve a plug out of By the time I found the pump and made it back to the tractor all of the air was out but I had probably only lost 10 to 15 gallons of water so the only amount of air needed was to make it round again and pressure it up to enough to go back to work probably the equivalent of the amount of air in 3 car tiresQuote:

An early form of a LPHV system?.
Yes lead dust is a lot heavier it does have a few pitfalls though. # 1 it is way more expensive than water #2 farm equipment doesn't get used every day. there are times when a tractor may sit for months and not get used the dust would have a tendency to settle and pack down also unless the tire was pressurized with nitrogen or another dry gas the moisture in the air would cause a layer of oxidation allowing the dust to clump probably never be a problem for construction equipment that was used a lot but if you had to drive the tractor several miles before getting to the fields it might be a really unbalanced bumpy ride for a while.Quote:

Most of our tires were tube type so the fluid was pressure fed into the tire when the tube was new and had no air in it almost ZERO air. the tire that I punctured was on the newer John Deere and it was tubeless so it had water and air, and until the puncture not a whole lot of air either but there was no way I was going to be able to lug a 20 or 30 gallon drum of water and a hand pump to pump it back up to 35 or 40 PSI with water it in the field
When I was stationed in Germany in the mid 70's there was this one German local who didn't have an air compressor but would touch up the paint jobs on cars in his garage he would haul a couple of truck tires at a time to the local service station until he had enough of them to use as an air supply for his job if he ran out before he finished he would use the oxygen tank. seemed to me that it would have been cheaper to just buy an air compressor
