FA: Dumore Tool Post Grinder Inserts, K.O. Lee Index Disc and other metalworking items on Ebay
I previously listed these Tool Post Grinder Spindle Inserts as a set on
Ebay and they did not sell although I had many watchers. I am re-listing them individually. I am alerting this group because, as you are probably aware, these inserts are very hard-to-find for sale independent of the grinder. Please go to the following Ebay links to see the Dumore inserts: Ebay Item No.: 7606809797 Link: http://cgi.ebay.com/ws/eBayISAPI.dll...MESE%3AIT&rd=1 Ebay Item No.: 7606810929 Link: http://cgi.ebay.com/ws/eBayISAPI.dll...MESE%3AIT&rd=1 Ebay Item No.: 7606812039 Link: http://cgi.ebay.com/ws/eBayISAPI.dll...MESE%3AIT&rd=1 Ebay Item No.: 7606813161 Link: http://cgi.ebay.com/ws/eBayISAPI.dll...MESE%3AIT&rd=1 Ebay Item No.: 7606814190 Link: http://cgi.ebay.com/ws/eBayISAPI.dll...MESE%3AIT&rd=1 Ebay Item No.: 7606815347 Link: http://cgi.ebay.com/ws/eBayISAPI.dll...MESE%3AIT&rd=1 Ebay Item No.: 7606816411 Link: http://cgi.ebay.com/ws/eBayISAPI.dll...MESE%3AIT&rd=1 Ebay Item No.: 7606817416 Link: http://cgi.ebay.com/ws/eBayISAPI.dll...MESE%3AIT&rd=1 Ebay Item No.: 7606818193 Link: http://cgi.ebay.com/ws/eBayISAPI.dll...MESE%3AIT&rd=1 I also have the following items up for auction that may be of interest to this group: K.O.

I did oil it to the gills, to no effect. When I turn it by hand, it feels like gravel in the bearings, and as it ran it got hotter, and it tightened noticeably. I stopped it before it locked up. I bet the bearings are toast, so I have little to lose. Joe |

I inherited a Series 11 from my maternal grandfather, long before I had any idea what a toolpost grinder was. I pulled it out of dusty neglect and ran it, but the spindle bearings don't feel right, and heat up if the unit is run. The motor is in perfect condition. Interesting -- one of the bearings in my *motor* feels lumpy, but the spindle bearings are in great shape. Do you have the manual? Don't I wish! I presume that you don't, either. If I could get it, I would scan it and make it available for download, as I have done with my manual for the Dumore drill sharpening setup, which handles from 1/4" down to #70 drill bits. I'd like to take the spindle apart and see if I can fix it. If spare parts are available. Not from Dumore, at least. Same for the manuals. I don't know whether it is obvious on yours, (it was rather hidden on mine), but there are a pair of holes in the faces of the bearing caps for a two-pin spanner to use to unscrew the caps. Do you have the wrench for holding the pulleys still while you undo the nuts securing them? I'm going to have to make one. I just made a wheel guard for mine for the larger wheels (if I can ever get the nut off the smaller pulley on the spindle to swap them for slower speeds for the larger wheels). I also need to make the adaptors for mounted stones for inside grinding. I *think* that the thread on the business end of the spindle is 1/4-32, and have just ordered some taps and a die for making things to fit -- and for cleaning up the threads on my spindle. There appear to be three lube points for the spindle -- one with the flip-top lid near the center, and two with felt plugs under hollow screws near the ends -- probably for small needle roller bearing cages. The bearings in the motor are sealed, and I think that I'll need to replace one -- the one at the pulley end.

Interesting -- one of the bearings in my *motor* feels lumpy, but the spindle bearings are in great shape. I bet replacing a motor bearing is easier than a spindle bearing. Yep! As long as I can find the proper replacement. These are wider than I would have expected for the diameter. I'll have to dig out the number from one and see what I can find to match. Do you have the manual? Don't I wish! I presume that you don't, either. If I could get it, I would scan it and make it available for download, as I have done with my manual for the Dumore drill sharpening setup, which handles from 1/4" down to #70 drill bits. No manual here. Anybody? Please? :-) I'd like to take the spindle apart and see if I can fix it. If spare parts are available. Not from Dumore, at least. Same for the manuals. I'm hoping that they used standard bearings. Perhaps -- but no bets there. Especially in the spindle. I don't know whether it is obvious on yours, (it was rather hidden on mine), but there are a pair of holes in the faces of the bearing caps for a two-pin spanner to use to unscrew the caps. The spanner holes are quite obvious on mine. I'll have to make a spanner to fit. They were plugged with goop from the polishing wheel which was packed on it, so not very visible until I cleaned them out. Are the screw threads normal (right-handed) or reverse (left-handed)? I don't know. I never have felt the need to pull those caps off, since my spindle runs smoothly at present. Do you have the wrench for holding the pulleys still while you undo the nuts securing them? I'm going to have to make one. I just made a wheel guard for mine for the larger wheels (if I can ever get the nut off the smaller pulley on the spindle to swap them for slower speeds for the larger wheels). I don't think so; I'll have to look again. The belts are flat and the pulleys are smooth and crowned, and a steel-jawed wrench would chew the pulleys up I would think. Unless there are holes in the pulley disks to admit the pins of a spanner. I expect the wrench to be something like the one for zeroing a micrometer -- a quarter circle or so, with a spur to go into the slot in the hub which engages the flat on the spindle. I bet people just grabbed the bigger pulleys by hand, or used a strap wrench on the crown. The larger pulley came off nicely with just that -- a hand grip. The smaller one (on the spindle) is too tight. I think that I'll have to make a collet style clamp for the OD to hold it unless I can make a working hook wrench as above. Are the pulley nuts right-hand, or left-hand? The one on the motor is for sure right-handed. The spindle *look* right-handed from what I can see of the threads, but until I get it off, I can't be sure. If you can get the nut off your spindle end pulley, you could tell *me* which hand it is. (Which side has your smaller pulley -- the spindle or the motor?) I also need to make the adaptors for mounted stones for inside grinding. I *think* that the thread on the business end of the spindle is 1/4-32, and have just ordered some taps and a die for making things to fit -- and for cleaning up the threads on my spindle. There appear to be three lube points for the spindle -- one with the flip-top lid near the center, and two with felt plugs under hollow screws near the ends -- probably for small needle roller bearing cages. I found three as well, and filled them all with oil. Good -- a light spindle oil, I hope. The bearings in the motor are sealed, and I think that I'll need to replace one -- the one at the pulley end. On mine, the bearings are not equally toasted, but I'll replace both if I can. The one on the free end of the motor is in very good condition, absolutely free motion. But, I'll probably at lest buy two bearings so I have the option of replacing it at need. Good Luck, DoN. I wish luck were not required, but Thanks. And the same to you.
