Hello Drew,
I just caught this thread, and remembered what we used to do with spot welds
on old race car tubs and such. When we could, tied the piece to the mill
table and used a slightly over the diameter of the spot flat mill to erase
the spot to the interface. When it was difficult to move the car to the mill
table, used a magnetic clamping attachment that held the 3/8 drill motor in
kind of a drill press arrangement and put the mill tool in that - got a
little chatter sometime, but better that drilling out and having to fill the
hole. On curves and non-magnetic parts, it was more of a challenge.
How's tricks otherwise? First Sat. in May is approaching again.
Regards,
Michael Lowe
