A little late to the party, but....... I've drilled out the tool bar holder (what Bader calls the "Heel") to accept a 3/16" pin that aligns the tool bar after each change of attachments. Before drilling the round end of the tool bar, first remove and drill the holder/heel; re-install the holder/heel; then insert the tool bar, get it squared up and running smoothly; then remove the contact wheel, or platen , but leave the too bar in place; remove the two bolts holding the tool bar holder/heel in place and bring it to a drill press (with the tool bar still in place) and drill out the tool bar. Repeat for each tool bar.

One other change made a big difference in tracking. Bader sells an upsized spring (if you have one of the earlier, whimpier versions).

I agree with others, in spite of the less than optimal tracking system and tool bar set up, it's a very solid, well built machine. Bader uses machined axles, as opposed to off the shelf bolts, and very high quality bearings.

Does anyone know the approximate gross weight of a Clay Spencer Tire Hammer with a 6" anvil?
thanks

In the Spring 1984 issue of The Anvils Ring is an article by Russ Swider called "Hand Held Air Hammers - part II" covers tooling and cutting, slitting and punching.

No matter though, Sipola's work is impressive!
