My lathe is an old South Bend and can only cut metric threading using added transposing gears. Unfortunately, that means the thread dial indicator will not work and I have to leave the half nuts engaged and wind the bit back after each threading pass by reversing the motor. It's a pretty slow process for me. Any local machine shop that has a metric lathe should be able to turn out an adapter for you. The stock I started with was a thick wall tube of 6061 aluminum with 2" OD and 1" ID. A 2" solid rod would work, too. It is a cruel fact that the little scopes were available in the USA - where metric "home shop" lathes are rare and the scopes were NOT available for low cost in other countries where metric lathes must be common. - Bill</blockquote>
