need bigger nuts
I have an old woodworking lathe with a 3/8" fine thread tailstock spindle
instead of a taper. I bought a Morse tapered live center, knocked the taper out of the bearing and turned down a 3/8" fine thread nut to fit inside the bearing. There were 2 problems with this: 1) in order to fit, I could only turn down the sharp edges of the nut - I'd prefer it was round for a better fit. 2) the bearing is as deep as the nut, which means the live center has to come off the nut so I can unscrew the nut from the tailstock with pliers. I'd rather have a longer nut and only turn down half, leaving the other half accessable to a wrench. Do they make 3/8 fine thread long nuts (I think they're also called couplers?) and/or do they make 3/8 fine thread nuts with wider diameters? If so, where would be the best place to find them? I've tried an industial supply store as well as the local Home Depot/Canadian Tire/Kent/Home Hardware. If I can't find them, it was suggested I get a piece of hex stock, drill and tap it, then turn it down. Where would I find small amounts of hex stock? Thanks, Shawn -- Shawn Wilson http://www.glassgiant.com |

I'd try Fastenall for the special nuts. They have a larger selection of
anybody. Look at fastenall.com for location nearest you. McMaster Carr would have the hex stock. Karl |

Thanks, Shawn Much better to get a chunk of hex stock the size you want, turn it to fit the center, and drill and tap to fit the spindle |

No luck at fastenall.com - it appears to be a search engine booster page and not a real site. I searched McMaster Carr site and MSCDirect for the nuts - no luck. So it looks like I'm probably down to hex stock tapping whether I like it or not ) I searched for "hex stock" on the mscdirect.com site and came up with nothing. Is there another name for it? I apologize if that's a stupid question. I'm a bit out of my element here. Thanks again, Shawn |
