I have none of that stuff. I have even contemplated making a new saddle, but there isn't enough bed width to make it worthwhile. But now that I have cut up part of that hat, I might consider bed wipers. > > The original Homier 7x was that version and it was pretty much ready to > go out of the box. Probably even Homier's is the junk model today. Not even listed on their site, I just checked. I see the Bolton 11x28 is on sale now, $2588+ship. They don't some with any "accessories" though, so first extra is a bigger 4 jaw, and a decent tool post. $500. Or more. Nearly 500 lbs, should be stiffer. Site propaganda is amazingly devoid of real facts, mostly sales speak. 1.3 horse VS motor, 27" between centers, 1.5" spindle bore.
