Default Small Tire Machine

Anyone here made their own small tire changing machine? I know I can buy one from HF or other places, but I'd like to make my own. If someone has can you post some pics or drawings?

That one looks like just a bead breaker. I am looking to build a air operated type. one way for bead breaking and the other way as a hold down for removing the tire. I need a hydraulic/air cylinder about 4" diameter that has a rod going through both ends so I can operate it each direction. I have no clue as to what that type cylinder is called. I may have to make one from scratch.

Find a old manual one and copy it .Years ago a bil that is now dead made one welded up the threads on the vertical and talked a machinist where he worked to cut the top part . Bead breaker went on shaft and levered to break bead .just a 5 ' bar to dismount and remount . Heck it all came out of company scrap pile .Knowing him probably paid to make it .

Thanks for the offer Mike, but I have decided to make one like this one. Just have to find a double ram air cylinder. The rest of the parts are easily made.

Milo, I was going to suggest taking 2 single ended cylinders and fastening them butt to butt, and then I priced a 5" bore x 10" stroke at Burden Surplus and they want $500 each.
My second thought is to make your own cylinder with tie rods and turn the end caps on the lathe. Pistons are just a plate with a couple O rings.

I have built a one way air cylinder before. This should work for a two way. six inch exhaust pipe may work for the cylinder. That is what the cylinder on my tire machine is made of.

That is exactly what I will probably do.

Still have it and it is working well. Problem with it is it will not do small ATV type tires.

I plan to use a thin wall tube of some sort Just have to find one with no seam. I can build a piston fairly easily and the end caps will be pretty simple too. The two way valve will likely be the PITA. One side has to exhaust will the other end presurizes. Have to give some thought on the valving idea.

This one will be able to do any size tire, which will be a plus.
