good morning to all(at least it's morning for some of us!)...the swivel bearing is an excellent idea, but due to it's overall size, it seems it would take a bit of machining and major modification to the whole gear carriage to make that happen...double checked the taper situation this morning and there will not be a problem with doing tapers on my extended machine if i just loosen the split collars a bit...not sure if there would be an issue on a 1200 or 1500...and then there is the bronze bushing in the middle gear...there is a decent amount of play with that gear, which i am not going to mess with(for now, anyway!...LOL!)...excellent pick up by tim, as i did have to cut a little bit off the end of the idler gear carriage to allow the smallest gear to be used...joe
