Hey Lee, hope it is not to much to ask but would you care to share the rest of that project? Will love to see it! also! may I ask how do you hold to a really nice and steady RPM? I use the reduction hoping to have a really neath and steady RPM. but I find this to be very hard! even when I manage to have a good RPM lock on. As the cutter take material off the stock.. it reduces the RPM! making a nightmare to have a pristine Thread.. Ho and by the way! I have a very nice CNC4PC RPM gauge that is very effective and works flawlessly..
