>I have had an ongoing problem with the speed controller on my Delta 46-755X 16” lathe. When setting the speed above 2400 RPM, stopping the lathe via the “STOP” button and restarting the lathe with the “RUN” button the lathe will spin up to around 2400RPM and immediately slow down to around 300 RPM. Delta replaced the controller twice with varying results. The last controller does the same thing but only with the “Acceleration/Deceleration” switch set to “FAST”. It functions properly when the switch is set to “SLOW”. Delta’s final response to me was “Don’t set the switch to Fast and live with it”. This is not what I expected from Delta as they have had a great reputation for support, I would surmise that this is what we can expect in the future as Delta is now governed by Black & Decker. This is my last Delta purchase.
