I’m planning on buying a Sherline lathe but am confused as to which I should buy. I’m in U.S. but it seems most measurements are made metric and that might be more applicable. I do work on mostly American clocks.
My suggestion is buy metric and a digital calliper and micrometer so you can easily convert to imperial, my reasoning is that most clocks apart from American and very early clocks are Thury, metric or BA ( even BA is based upon the metric measurement ) but that is my personal opinion, I have an English Pultra P type and both metric & imperial collets and I use both regularly.
