I’d like to slow down, as much as possible this black and decker drill motor. I have it wired on a dpdt switch for fwd and reverse. I’m using it for a homemade router lift and I only need it in short burst to make small height adjustments. Was trying to make it with stuff lying around the shop. Or ... any suggestions for a similar set up? Need it to be 110v and a way to connect the drive shaft to a piece of 3/4 all thread.
