Hi. I bought a SB 9 with change gears that does not have the gear covers. For safety's sake, I would like to get or make one. But, this one does not look like anything for sale on Ebay, and it is not clear if anything from lathes.co.uk or the catalogs match it. The lathe has a flat belt underdrive, and there are no screw holes for the gear cover. I see one which has a ball knob on the bottom. Is that just a handle, and the cover just rests on the headstock? Or is this a different model? There are two small depressions in line with each other in the rear, and they may be where the pivot screws hinge. If anybody has a pointer for a picture on the Internet, that would be really helpful. By the way, there are no interlocks that depend on there being a cover and that cover being shut in order to run the lathe. It runs just fine without it. Two pictures are attached. At least someone else may be able to see them in a web search.
