Re: grizzly gunsmith lathe tail stock won't lock tight.

Well diagnosing at a distance is tough ! Have you tried bluing up the clamp piece and trying the fit to the bottom of the bed? Only 2 things now come to mind is the bed clamping surface is not parallel to the upper surface or that surface is not very smooth. like I said blue it up and see how good t...

Re: grizzly gunsmith lathe tail stock won't lock tight.

Well I have a Chinese 12X36 and have been around a lot of that type lathe. Before he closed his shop my machine dealer friend sold 6 or so of the "Shop Fox" brand [Grizzlies other label] and I assembled everyone for him. Did NOT see any issue with locking the TS ,they too had the 1/2 Sq. drive shoul...

Re: Sears & Roebuck model 109.20630 metal lathe

These are easily restored to make nice bookshelf displays. I think of them as antique model lathes ;) Yep ,just a little bigger version of a "MANSON". I think I paid $40 for the one ,109, I had ,had to do some tinkering to make it work? and then sold it for $100 . I think a Harbor Freight 7X12 work...

Re: Sears & Roebuck model 109.20630 metal lathe

Just bought one of these and it seems in good shape. One issue I'm having though is I can't get the tool carriage to MANUALLY move towards headstock. It WILL move when engaging the thread gears (forward AND reverse); but when I put gears into Neutral and try to turn handwheel on end of lead screw I...

Re: Estimating chuck speeds

Welll according to the pictures you posted of your lathe in the other thread you HAVE a speed chart!! With standard pulley setup those lathes went from 28 to 2000 spindle RPMs. 2 ranges of motor to countershaft and 4 on the spindle plus backgear.

Re: 1141 HR - any advice on this stuff??

BadDog has it. I bought a set of those hardness checking files 5-6 years ago and I use then regularly. not tearably cheap as I recall a bit over a C note for the set. People are always showing up here with can you , mill -turn etc. They tell me a lot more than just trying to nick with as file corner.

Re: Champion Tool Works 12" Lathe - Carriage Auto Feed

Well with a antique machine like that anything is possible. Atlas/Craftsman lathes , some had power crossfeeds but, all used the half nuts for slide feed. Your lathe may work the same.

Re: Champion Tool Works 12" Lathe - Carriage Auto Feed

You sure that lever does not have 3 positions ? Neutral in center,slide one way cross the other that is the way those are usually set up. some lathes however did not have power cross feed.

Re: Valve Guide Material?

My 500cc RE Woodsman was an enduro style bike ie with lights etc. I fixed it up as a restore/rider not to fancy. I did take it out off road several times and it worked well handling wise. This was in the late 70s and just before the Jap long travel suspension bikes started showing up. BIL had one of...

Re: Jet 1236P Tailstock

Well I think I would try a non welding approach . Looks like you have a machined flat surface on each end ,bolt on a piece of 3/8-1/2 thick strap of the appropriate width .Clamp everything down to a flat surface ,mill table whatever and start drilling . I have one or 2 more ideas for a non weld repa...
