Thanks for sharing that John, could come in handy in a later plan..... :thumbup:

Jadecy:
On the initial topic - I had all kinds of walking hole problems until I got a DRO. Dial indicator with magnetic base was my old method and man did the error multiply as I went along! My bidder problem is the need to get new screws and nut for my mill. It is a 196? mill and the screws show it. Lots-o-spin in the wheels before anything moves!  :ddb:

Without the DRO with that much backlash it is almost impossible.

My bigger problem is brain lapses or whatever ya call em. Study the page, mark out the part, look at the drawing again, drill the holes. Everything looks great....wait a cotton pickin minute! DOH! DOH! DOOOH! I was looking at the wrong hole on the drawing when I picked my drill bit and now the perfectly positioned holes are way too big. Fortunately on that one I was able to make inserts to fix it. I could have welded it up but with that particular casting I didn't want to take additional unnecessary chances. A half hour at the lathe and all is good. I have plenty of others that ended up in the bin.

 :D

This is just on turning and milling jobs, no fabrication.

Hello John, can I ask you how you keep the weld heat from affecting the rotor windings...or perhaps it does not harm them?
All the best for now,
