Good day :
I am looking to make a plastic or brass mandrel for 1/2" tubing. To that end, I need to get my feed to be in the range of 1.25 Threads per inch. Current machine can do 1/8" per Rev. so I need a 6x improvement on this.
Option 1.) making / or buying some spur gears to get the gearing up to the 0.75 inch / rev., But there is a bit of cost and time to do this, as well as additional load on the gears. Currently my leading option but it is not a good one.
Option 2.) use a motor connected to the apron feed wheel and a encoder connected to the spindle. Even more $$ and time, and not to short of a full cnc.
Option 3.) convert to full CNC big $$$'s and ? is it the right thing to do. (My lathe is a 9x20 type. lite home stuff +/-)
Option 4.) ???? Any great Ideas would be very welcome! ( Note: I am not looking to have the lathe motor bend the tube! = not near enough torque.)
