Unfortunately, in describing my Taper-Attachment-Follies, I'm reavealing the extent to which I qualify as a Journeyman Ding-Bat.
After a tight cross-feed nut and gib fussing, the taper attachment governs much of the cross-slide's behavior. (Of course, that's an over simplification, but not by much.)
Problems I've encountered (read: created for myself).
1. Never try to save time by removing the taper attachment as a complete unit. While straightening the cross feed screw isn't that hard, it wastes more time that you'll save. And the ulcers when it's a new one. Oy!
2. If your attachment is the version with the two ball bearings (one at each end of the cross feed screw sleeve (Part No. *AS858R1 in Form 922D Sec. 2), you can't just "sock 'em and lock 'em", and commence ta' makin' reactor parts. You will find yourself endlessly futzing with gibs and developing forearms like Popeye, wondering if now is the time to learn how to scrape "V" ways or endlessly cleaning swarf that isn't there. The bearings have to be adjusted and locked, but trial and error (this is where some one comes to the rescue with a ridiculously simple procedure that should have been intuitive to the dullest apprentice) is the only path to redemption. I had a new cross feed nut and screw, so there's one variable eliminated; the slap in the key/slot relationship between the Front Taper Attachment Screw(Part No. *AS482R2) and the aforementioned real cross feed screw itself can be parsed out if you eyesight is 20/5. Best be takin' backlash notation prior to disassembly. Already apart? Nevermind, just keep foolin' with the adjustment until you're happy with it. It's surprising how good you get at that after only a couple of weeks.And, as for the guy who designed the notion of using two thin nuts, well, we'll be hunting him up for a talk together. I finally got a couple of pump wrenches, drilled holes at the end of the handles, and hung them on a peg inside the cabinet.
Heavy Ken is right on it when he says that the taper pin is the place to start, then proceeding to the gibs (all of them).
HEY, WAKE UP!
Actually, I'm nodding off myself.
While someone will, no doubt, observe, and quite correctly so, that this didactic is about assembly, not disassembly (that you have asked about), I think that if I had given more thought to what was going on while the thing was in operation, there would not be two .45 caliber bullet holes in an otherwise lovely gray cabinet.
I'll keep an eye on the e-mail notification thingy.
Wally.
