Tool Rest tightening

Hi Me Again

I have a really old Record lathe. I can never get the tool rest to tighten properly. Actually it needs a tap with a hammer to do the trick, which really peeves off an associate of mine. He suggested cutting the tool rest holder with a hack saw to allieviate some of the holders strength, to allow it to collaspse easier on the tool holders shaft. Shims wrapped around the holders shaft don't do much either. Does anybody know a supplier for a new tool rest holder for the Record lathe.Or any Workable suggestions.

Kerf cast iron? Not a good idea at all. Too brittle.

Now, knurling the steel shaft of the rest might provide a bit of grip if undersized, or filing a small notch at the end of the screw that holds the post. But don't modify cast iron.

STOP IT! You're perpetuating a stereotype. %-) Figure out what is causing the problem, really, and fix that.

There is an adjustment bolt on the bottom of the banjo on my midi lathe that can be tightened or loosened to adjust the amount of pressure you need to use on the handle. Of course, sometimes I get a little lazy if it gets vibrated out of adjustment, so I've got an 18" (give or take) piece of glavanized electrical tubing left over from another project that I slip over the handle and use as a cheater bar untill I finish what I'm working on. It works great, and is a whole lot easier on the tool than hitting it with a hammer. Same logic applies for just about any bolt, IMO- a lot of guys at work like to hammer on the machines, and then wonder why they break. Smooth, steady pressure with a lever keeps your amount of force controlled, and doesn't ding up your tools.

Actually a proper machinist ( That is one who makes his living by that trade ) fixed it. First he showed me that by repositioning the tightening nut the tightening handle does not touch the rest. Then with a vise he squeezed the holder a little so now it tightens nicely without a hammer.

Glad to hear it. I've used a hammer for years as well, but I prefer not to tighten with it. %-) Should be starting to warm up and get real pretty up your way. Nice place, good seafood.

Shows you that a hammer is useful to solve all sorts of little problems.

Also try a nylon washer under the tightening handle will allow it to snug up tighter with less friction.

Typical June for this part of the world. Seafood! Well if you can afford it!. We went out on our wedding anniversity and bought chinese food. The chicken in the SOO GUY was paper thin and we informed them that we feed our dog better food than that.

Take Care Keith And thanks for the inspiration to find out what was really wrong with the tool rest.Sometimes we get stuck in a rut and need good advice.
