What does everyone else use to press the morse taper centers and chucks out of the lathe stock? I didn’t like using a screwdriver, so I took a couple of minutes and put this together. I’m not sure what you would call this tool (hence the stupid title) ... maybe a punch? Anyway, it’s just 5/16” rod epoxied into a fir handle. It has enough mass that a couple of taps usually loosens the fitting.

Peter mine came with my Delta VS lathe. It has a brass end on it for safety.
Good idea for the guys that don’t have one though.
I used another type a few years ago with a metal weight on the shaft that you slammed againt a stop to act like a dead blow hammer.

Looks similar to what came with my lathe, so it should be just fine!

Got one with the lathe, but with a silly plastic knob – yours looks much nicer.

However, I have never used mine yet. I have never used a morse taper in the head stock and in the tail stock, I just have to reverse the quill and it knocks out the the taper for me.

You guys have nice lathes. Mine isn’t really a part of my business, so I have a less-expensive one that didn’t come with such a tool … or a reversible quill! Brass would be nice, but I figured (hoped!) the round stock would be softer than the hardened MT. One of these days I’ll throw some finish on the handle.

I use something similar to yours but without the handle :)

I can just see the wheels turning in the R&D office of Veritas/Lee Valley on how to improve on this design!

I never knew there was really an official tool. I use a 1 foot drill bit extension thingy that someone gave me many years ago.

Yours looks very handsome.

It looks like it could also serve as a burnisher for a card scraper.

What kind of lathe do you own ? Even my JET mini lathe came with its own ” Un-stuck-ifier ”....LOL I like your idea with the wooden handle and maybe I’ll unscrew the plastic knob that came on mine and make my own knob out of Rosewood or something nice like that …Thanks for the inspiration and Happy Holidays to you and yours : )

Nice one!

Generally this tool is known as a “knock out bar”.

Peter, I always heard them called a Knock-Er-Out-Er. But I could be wrong. Nice job. I never seen a lathe that didn’t come with one though. I always like to replace those plastic ones that come with tools, like on a drill press. They don’t even have to match. One other thing is if your live center has threads on the end, you might consider getting a bolt to go in there lest you bugger up the threads. Do it now before it gets stuck too tight and you really have to Un-stuck-ifie it.

I bought my lathe second-hand (I won’t say used, because I think the guy assembled it and then let it sit untouched in the garage for a few years). There may have been an un-stuck-ifier with it, but if there was, it was lost in limbo.

@rance – that’s a really good point. I don’t think it is threaded, but I’ll take a look next time I knock it out.
