I'll make a final decision when I actually see it all in the flesh, but I'm thinking that I won't fit the inverter/controller unit in the traditional place on the stand below the gearbox. I think it would be prone to getting oil and swarf all over it, and I'd probably end up putting chuck keys on it. Behind my lather is a set of dexion shelving with wooden shelves - I use the upper shelves for lathe tools, chucks, centres, collets etc. My current plan is to mount the control unit flat, screwed to the underside of a shelf. That puts all the controls at eye level, just to the left of the chuck. That feels like a better idea (I can always move it of it isn't).AS
A point of reflection - the motor I removed is the size and weight of a small house and is good for half a horsepower at 1,425rpm. The motor I'm replacing it with is a similar size and weight, and is good for a whole horsepower at 1,425rpm. In one of my RC aeroplanes I have a motor which is 50mm diameter, 55mm long and weighs under 350grams which I regularly use at 1.7horsepower at 9,200rpm. So why do I not simply get another one of those with a 6:1 reduction drive for a fraction of the size and (with speed control) half the price? It would probably need a flywheel to cope with the initial tool-contact loads, but what am I missing?AS
