Oops! Broken tool rest

Get it brazed back together

>Somewhere within a few miles of you, there is sure to be a competent welder who will braze the pieces back together for a very modest charge.

>...or, now's as good a time as any to buy a MAPP gas kit and some silver braze from your local welding supply and learn to do it yourself.

The guys at the welding shop'll probably coach you.

But Fusion brand silver braze ground in flux from brownells.com melts at 1100 degrees and will do cast iron. Just bury the brazed cast iron piece in ashes or a bucket of lime to cool slowly.

>I had one break on a previously owned lathe. As Ellis said a welding shop will repair it. Whereabouts in south Jersey?

Mike - I'm in Florence. (that's Exit 6 for those that track Jersey via Turnpike exits.)

Been there, done that!

>I had exactly the same thing happen on my old Sears 1236 lathe. I had mine brazed at a welding shop. that worked quite well, but...it broke again shortly there after. I was told that the old cast iron was very brittle and wouldn't stand up to the brazing. I was given a recommendation to have a machine shop make a new replacement from steel. I found that it would be quite expensive to do and deemed that the lathe was not worth the expense. I bought a new lathe instead.

This is my experience with the toolrest on my old Sears lathe. Hopefully, your's will pan out better.

>Tom give me some dimensions of the base, like the length of the slot, and width where the bolt goes through that fastens it to the lathe bed. What size bolt is used and what is the tool post diameter. I have some spare parts here that once belonged to my grandfather, the lathe was a Walker Turner sure looks similar, if I think it will fit, its yours for the postage. I live in Saint John, N.B. Canada, 100 km north of the Maine & New Brunswick border on the seacoast.

To prevent brittleness...

>The repair needs slow heating...preheating in an oven before applying the torch....and slow, 24-hour cooling in a packed bucket of lime.

If your welding shop ain't doing that...and many aren't...then you are better off learning how to silver braze and do it yourself, as it's neither difficult nor requires a big gear outlay.

MAPP gas....use two torches if the workpiece is too thick for one....Fusion silver braze ground in flux....and a bucket of garden lime.

>My old Blount lathe had no banjo when I got it. I got a plate of 3/8" steel, marked out the slot for the bolt, drilled a hole at each end of the p[roposed slot and cut it out with a hacksaw. Then I had a length of suitably sized pipe welded on to hold the tool rest post. I drilled and tapped a place for the adjusting screw and used the resulting pieve of equipment for forty years. No need to scrap the lathe.

>Bruce:

Here are the dimensions of the base that broke. The slot is 6 1/2 inches long including the 1 inch hole for the mount. The slot is 1/2 inch wide. The tool post hole is 13/16" but may have started life at 3/4". The overall length of the part is 9 inches by 2 1/4" wide.

Let me know if you need any other dimensions. Feel free to email me directly. If you have a part that fits just let me know where and how to send the money, I appreciate the help getting this going again.

I've been eyeing new lathes in the Grizzly catalog but prefer to learn more about turning before purchasing a new one.

>Tom get it welded, Flame welded that is, its not the same as brazing and it is stronger, we used to do the flame welding and old cast is usualy better than the stuf they make now, it gets brittle when it is heated and cooled, thats why the parts of a stove would get brittle, anyway the welder should heat the whole piece and it should be kept hot while welding, and than kept so that it cools down slowly, cast does not give like steel and will break easier than steel, we would stick it in the ash and sand next to the forgeing fire, you can use hot sand or ash, never used lime but that might work also.

One other thing though is why did it break, bold head worn or what, you should fix that or else it will break again.

Have fun and take care

>If you have a buddy with a welder a couple of pieces of square stock, some schudle 40 pipe and a nut would make you one out of steel that won't break.

The 1" x 12TPI spindles on some of the Grizly's are hard to find accessories for.
