This week's one, in progress (still need to harden, temper and hone). It's a set of "telescoping" plug cutters for veneer repair. The smallest cuts a plug for a standard drill size, and the one above it cuts the plug for its hole, and so on:
This is nothing fancy, but here is a 1" boring/I.D. threading bar I made, threading insert on one end, then turn it around and you have an inserted boring bar...
A while back I seen a neat retractable threading tool holder that fit on a quick change tool post. Was probably a home built part as I havent seen one in a catalog. Did any one see it or have a link to it.

Hi Joe,
Here is the one that started everyone else making them recently. Evidently it is a tool that was made a long ago, so it's not a new idea. http://madmodder.net/index.php?topic=2323.0
There is also another one made by someone else on that site.

Was it a bit like this?
There's about 1/8" travel and it retracts very smartly with a flick of the lever.

Ludicrously, it's on a Hardinge with retracting topslide, but for square threads or buttress it's surprisingly handy.
There is a trade school in Wisconsin where the students build a vertical mill as a project. I owned one of the earlier ones for a while, and milled everything from wood to steel with it. I wish you guys could see one of them, they are pretty cool.

tool post made for my Mazak Nexus Lathe, I needed 2" extra lenght for a long drill, its a shame buying a new machine without realizing is too short for many aplications , I was lucky it was 2" only and solved the problem doing the tool post.
After a recent installation of a surface grinder at my dad's shop, I had bought him a couple of different wheels and some wheel adapters/arbors (whatever you prefer to call them.) It surprised me when he told me had had never changed grinding wheels that way before. The shops he worked in had always just removed the LH nut and taken the wheel off the adapter, leaving the adapter on the spindle nose.
I had a 1/2 hour to kill so I grabbed a piece of 1-5/8ths diameter 303 stainless and made this on his lathe. The rusty 1/2-13 hex head bolt was something he had kicking around, but it was the perfect length so it ain't changing.
I know, it's NOTHING compared to the beautifully-crafted weeks or months-long projects you other guys do, but I was proud of myself and my dad was thrilled to see how easy it is to change wheels now.
