Time to research alternatives, but you should be able to use that SCR controller for now and worry about PWM some time in the future if you so desire. I was looking at KBMM-125 controller. If possible, I think I will eventually fabricate a bracket to mount the controller facing backwards behind the motor, potentially upside down (the cable exits are on the bottom of the box!). The control board has a seven connections you will need to make, three terminal connections that a 10,000 OHM rotary potentiometer is connected to. I'm not familiar with either the treadmill controller or the the e-bike but speed/load regulation is a concern - if you set the lathe for a speed and then apply a cutting load, how does it handle that? In their place I used jumper wires to a 5k linear pot. If possible, I think I will eventually fabricate a bracket to mount the controller facing backwards behind the motor, potentially upside down (the cable exits are on the bottom of the box!). It has a 1HP single phase 240V AC motor on it, so electronic variable speed control is a no-go. 4000 seemed a bit much, so I scaled that back a bit too. Read This to Find Out Whether You Can Run a Portable Generator in a Shed. Not a bad thing necessarily for full size lathes turning large pieces from a safety standpoint but a real pain in the butt if your tuning pens at 3000 rpm and need to stop and inspect the wood frequently. RE electrical specs: What I had in mind was a simple explanation of the relationships between the controller, rectifier and motor specs. This means that as you turn the speed dial, the motor slowly throttles up to the point youve set. - with a simple disconnect for when I don't need it? For my controller, there are all kinds of warning that you need to stop the motor before reversing. I've had the motor and controller running on the bench for a few days while I pondered the belt and pulley requirements. Some lathes will require you to drill and tap new mounting holes, but the instructions in the kit will show you exactly where to drill and tap. Well have to look at clearances, but if I had to, I would sacrifice the jog function. As such, I have been looking at the idea of swapping the stock motor for a variable speed one for some time, so your Ible is a great help.Then it's off to the drill press.THANKS. You will need to fabricate a bracket for your application and mount the sensor and magnet. Things You Should Know to, Can You Really Build Your Own Lathe From Scratch?
