Default Follow up on damage sustained to tire bead breaking tool

Now have some pictures that illustrates the damaged induced by too much torque on stubborn CMP tires.

The "clsw" on the tool that actually assist in sitting/wedging the foot of the tool between the tire and the rim is the main part that has failed. The claw looks like the curved section from a 5/16 thick steel pipe....about 1.3 the circumference and has a small section of tubeing welded and pinned in pplace to pivot.

Earlier pictures of the tool only shows the plain curved section later model, such as ours, has had a small lenght of 1/4x1/4 steel added to the side of the claw for stiffness.....but not stiff enough as ourts bent just where the reinforcement ends.

Since the main body of th tool has not shown any trauma we plan to have a NEW claw cutout of 1 1/4 thick T1 steel plate with a thicker profile/

JUst as an aside we have used the tool with the existing twist and bent to derim a modern 900x16 tire off a modern rims and it still works fine........ but will need rebuild to work on tough cmp rims. We have kept the bad rim so we can continue the process with the beefed up tool at a later date.

Here are pictures....
