Made a tire bead breaker today.
I dont have a tire machine and dont like driving 2 hour round trip plus paying money to do a tire swap.
I bought a nice gravity balance with cones etc.
I have tire irons and rim protectors, but breaking the bead was a challenge.
I got an old piece of oil field pipe spool fromthe junk pile and spent 30 dollars at Tractor Supply.
Some metal strips for support on the wood, bolts and nuts & some straight pipe.
I had an old bike lift stop I cut and hammered out for the tire wedge. Pulled out the chop saw and welder.
It's super primitive, but it works great.
I will add, it was harder than I thought to get everything right s far as geometry.
