Hi all
Can you help a thick bugger out, I hardly use my lathe and want to repair some threads on the end of a motorcycle crankshaft, I did a little screw cutting several years ago and have a handful of 16er inserts but none in 1.25 , only 1.5 1.75 ,2.0 ,3.5,ac55 ( I bought a job lot of holders and inserts ).
Is it ok to use a 16er 1.5 to cut the thread if I make sure not to cut beyond what the 1.25 thread would be or do I need a specific 16er 1.25 , my plan is to line the insert up on the good part of the thread and run along the first 4 threads so I can put a M12 x 1.25 die on and know it won't re cut the good thread .
