What I found inside is about what I expected. pretty fair machine accuracy except for the threaded stuff. The worm gear wasn't, it was straight cut, hopfully at the correct angle to match the worm, which also wasn't profiled. The worm gear wasn't even pressed fully into place on the spindle, so I fixed that. Looked like the threads at various places on the spindle had intercepted several blows from at least a 4 lb hammer, but the threads were cut sloppy enough to tolerate that once they were cleaned of debris, with much of the debris haveing a reddish color and quite hard, hard enough to cause the jamming. I cleaned the worm and gear, but only removed the quite surplus grease on the outer of the roller bearing, and regreased the worm and shaft as I re-assembled it, now the backlash is about 1/8 inch at the end of the crank lever, was nearly an inch and a half before. And it turns fairly smoothly. And amazingly, even acc. the manual from grizzly, there was no ball bearing in th center dimple of the far end of the worm shaft for the adjusting plug to bear on. So all told this will be a high wear item. Very narrow contact between the worm and gear, and probably high wear, at least till it gets worn in between the worm end play and its adjuster plug.
But the ultimate insult, is that the chuck supplied, and the back plate I had to loosen by removing the worm, then placeing a screw driver against one of the countersinks in the front plate and beating it clockwise with a dead blow, had never been in the same building before shipping to me in separate boxes. So the first job once I get the motor installed, will be to use it as a lathe spindle and machine the backplate to fit the chuck. Registration ledge and bolt holes. The whole mary-ann. The chuck looks decent, but I've not put a caliper on it yet to see if its round. Scared of what I might find. This is too big, the post on my G0704 lacks 6" of being tall enough to use it comfortably, so I am debating with myself if a BS-0 might not be more usable in the long run. And probably have to wash, rinse and repeat all this again to make it usefull. Lets just say I am not exactly a happy camper over this turn of events. Thanks for reading my tale of woe. Normally, one buys a tool expecting it to be useable OOTB. This $600+ BS-1 is a very poor parts kit to make one that might be accurate enough. Has anyone else's experience been any better? > Cheers, Gene Heskett Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
