Retracting Threading Tool Holder

I bought the kit from Hemingway, http://www.hemingwaykits.com/acatalog/Retracting_Tool_Holder.html

It comes with all the steel parts in just saw cut from stock, bolts and etc. Full drawings that are excellent. I have received drawings from big business that were junk compared to Hemingway's.
It has approximately .125" movement. Since I do not have any Brit thread taps, I subbed with standard #8, 10 and 1/4" hardware.
I likely will make it again and make it part of the tool holder and make the handle smaller (it is mine, not as supplied, I have many of these knobs:nuts.

A very nice project that requires lathe, mill and drill press. A couple of weekends was all it took.

Nice looking job :thumbsup:
That should be very handy when doing threading jobs. If you have more pics of your toolholder, please post them up. Very interesting looking item to say the least. Appears to be a great kit for the money.

Good Job

Re: Shop made tooling

Wow this is stunning!!
I love the way you did it I'm preapering to make one of this for my Standard Modern lathe just the quick question how did you scribe the degree lines?? what tool did you use sharp point SS? and how did you do it can you describe quickly the process I think this is way beyopnd my machining abilties at this moment but I wouldn't mind find more about the process

Here are some pics of the finished kit from Hemingway.
Very inexpensive and I liked building this. Quicker than some projects that are still not finished!:whiteflag:

As I stated, I will reduce the handle size. The kit comes with a 3/16" rod with suggestion of turning a ball for the end. I do not have a ball turning tool, but lots of these knobs. With the handle forwards, you are on the top of the cam and 180 degrees to the back, the bottom of the cam. There is a spring return, the tool comes back pretty quick as the spring is fairly stout.

Thanks for the extra pics. That job sure turned out well, and the kit price is very reasonably priced. I think the handle looks fine really. With the shape and size it is, it looks to be right to me. If it had a small machined ball, it could be harder to grip your hand on it. Maybe its just me? If you don't have a ball turner yet, maybe you have a boring head laying around. If you look through this thread, I think you'll find the set up I use. Ive even cut balls with it on the milling machine too.

Actually I do have an abandoned boring head. It came in a box of stuff. I have not made a new body etc for it as I just have not needed one yet. It is 3/4" bored. I saw that ball turning setup earlier that is why it is on the table and not in the drawer!

If you make up the base for that, you could use it for ball turning.
I had made a ball turner for the 12X37 lathe I once owned. But have been using the boring head ever since I went to the larger lathe.

I have a few sizes of the cheap Chinese boring heads, a 2 inch and a 3 inch. They are from Busy Bee, and the arbours for them are 15 or 20 bucks. I bought a #3 M/T one, and machined it straight to fit my QCTP boring bar holder, and made a handle for it.

Works very well, and can still switch back the arbour to the R-8 for use on the mill. The QC boring bar holder can also be used for its original intended purpose. To turn balls on the mill, I just put the boring head in a chuck mounted to the rotary table, and the work piece in a collet in the quill.

Just multi tasks for the same tools.
Try it out before making a separate tool just for turning balls.
Those Busy-Bee boring heads are so cheap these days, you may want to look at those for boring on your Mill, and ball turning on your lathe. You can also do radius work too, and the BH allows you to stay close up to the chuck, with out a lot of over hang.

A Fileing Rest

An often overlooked tool for the lathe.



Mount the rest on a vertical slide,then square it up to the work.



using the guide washers file the RH side first, lowering the slide slowly, stop short of the depth you want.



Reposition the saddle to align the LH guide washers, at this point I like to add a saddle stop so I can retract
the guide to measure the depth of cut and then return to the same position.










Job done .)

Brian. I seem to have made a hash of the photo order, but in am shure you will get the idea.

Its amazing the talent that is here! This is a huge place for gaining knowledge! Glad I joined this site.
Everyone pat yourself on your back you deserve it!

How well does the Roto-Zip work for the mini grinder? Have you tied to hold a precision size like about 0.001? I have a huge Dumore and its about 40# with out the quill assembly on it! That would be Great having a small one like that. I tried a Makita die grinder but it was crap the mounting for its arbor was plastic just a small amount of load and I could grind cams for anything.

They pale in comparison to yours and I've had some of these in other threads but here goes in order: hold down clamps made from thick walled pipe, 2 tool bit height gauges, threading stop and a handy run out indicator all to fit lampost tool holders, a group of brass hammers, a tool bit angle gauge for a Williams holder and last a tool post grinder.
