Thx Underdog. I'll check that out.Motorhead, not sure I understand. I make custom hammers with cross drilled holes for nylon tipped set screws. I have to drill and tap those, as well as drill and tap the lug screw hole. Not sure what 'step' you're suggesting I skip.
Steve, instead of making your life difficult by using axle shafts, why not get some 1144 steel and make then from that.... It machines nicely, and if you want to harden it, you can do that too.... BTW, I've never bothered hardening any hammer I have made, and haven't had a problem yet.... Bob
I make hammers for the Marauder. The most recent one is being made out of some sort of 1.25" axle shaft. I turned it down to diameter on the lathe with no issues, and drilled thru for the striker hole and spring counter bore with no problem. When I went to cross drill it for 8-32 and 10-32 tapped holes, the cobalt drill wouldn't touch it. What type of drill bit do i need to drill this HARD steel?
