Is my old Delta Grinder Shaft Fixable?
I own an older Delta Grinder that I bought at a garage sale some time ago
for $5.00. I can't find a model number, but there is a serial number plate on the back that reads "16-204". It uses 7" x 5/8" bore wheels. Currently I can only use one wheel because the shaft on the left side is buggered up. But for $5 it is still worth it. The threads appear to be 5/8" acme type - left hand. There are hardly any thread left for the nut to grab a hold of. My question is, is there some way to build it back up and re thread it safely and at reasonable cost? I looked at the McMaster web site and can't find a listing for a acme thread die. MSC lists acme taps but not dies. Thanks again to all those who so willingly give of their knowledge on this NG. I appreciate it very much. Lane |

Why does it need to be big ? Make it 9/16 or 1/2 acme or any thread for
that matter just be sure it clamps the wheel before bottoming the thread. |

One of the major metalworking mags (HSM, MW ..) very recently had an article
on building up worn/munged shafts. I think that guy would suggest that you strip down the shaft, weld up the worn threads, turn it round again, and then screwcut the desired threads on a lathe. - GWE "Lane" lane (no spam) at copperaccents dot com wrote in message ...

Call Delta (1-800-GO-DELTA IIRC) and see if they have the part you're looking for. Sounds like it will cost lots if they have it, but you might get lucky. Regards, Robin |

I appreciate it very much. Lane Turn and bore a sleeve, and thread the other end. Secure it with a couple setscrews. You will have a longer shaft on that side of course so your guards will not fit. A perfect place to put that wire wheel that you dont want guards for anyways.

"DanG" wrote in message news:PPiEd.15287$4h.11493@okepread03... Lane, I know of no way to build the shaft back up economically. Is the entire shaft eaten up? Or can you use a wider or narrower stone/washer combination that would use good threads? It may be ideal for a wire wheel. Huh, now that is an idea. Some wire wheels have a very narrow bore. I'll check it out. Thanks for the idea. |
