Jim,
I must apologize!
When I looked at your tool on Jim K's website I saw the rounded end of the bolt and thought you had turned the end to that shape.
This time I enlarged the photo and I can see that it has a ball bearing on the end.
Jim also makes a GREAT brake bleeder:

This tool turns a PITA job into a piece of cake! For $75.00 one person can bleed the brakes in a GMC in 15 - 20 minutes.
More importantly you can flush the brake fluid every couple of years for the price of a couple of quarts of brake fluid preventing
corrosion problems and expensive repairs.
Regards,

Rob, one thing that differs on the TB tools that I make is, that they come
with a ball bearing on the end, and the end threads turned off ( not easy,
those are hardened bolts) . Also, the cross bar is tool steel, and the arch
is 4130 steel. Tough stuff. All my tools can be identified by a upper case
H stamped into the end of the cross bar for i.d. purposes. Just what I do.
