It's the entire cross-slide pushing back. It gets pushed forward, due to lash in the screw, when the tool is reset.

I just tested it, the email is working. Try copy and paste instead of typing it. Let me know what type/size toolpost you have.

Yes. I saw his and thought "I can make that, only Stupidly Simple".

...wait... old fellahs? Slow reflex. You'd think after living for over 50 years, your reflexes would get better in old age. Hence the saying, practice makes perfect.

Just reducing the stress and anxiety, skill still required.

@@phineasj.whoopee3301 Anxiety? sheesh. I loved single pointing, did a few quad leads in school just cause.

As currently designed, there is no place to put an opposing spring. A concentric spring is possible if added at the back end between the holder and reset knob. This would require about 3 inches extension behind the holder.

Gets pretty dicey with a threaded spindle nose.

No plans to apply for a patent. If it is even patentable, the cost of obtaining a patent, while high, is nothing compared to the cost of defending one. I'm happy just to make and sell them.

@@phineasj.whoopee3301 No patent - good man. I completely agree that the cost and hassle is not worth it and defending is a money pit. I send you my high respect and best regards from Victoria 🇨🇦

It’s in the public domain now. No chance of a patent.

@@lesmansom7817 That was the plan, I didn't intend to patent it and now no one else can.

I've done it before, but it can get dicey with a threaded spindle nose.

@@phineasj.whoopee3301 very true. Any tips to prevent it from unthreading? Maybe using some pipe tape to give it a tighter fit?

I used one a lot when I worked in the trade. Sometimes you still have to single-point.

I am simply making and selling them. If someone wants to copy the idea they are welcome to do so.

Each tool is individually fitted to provide the absolute minimum clearance, both in vertical and horizontal. Rigidity is not a problem.

That sounds like an entirely new device which would need a different mechanism

Never seen a lathe with a feed screw, only feed shaft and lead screw, the former shaft being smooth with either 1 or 2 keyways. Smaller lathes that don’t have a feed shaft and having only a leadscrew for both functions, being the exception. I’m curious though what you mean by cutting the oddball pitches via the feed shaft. Is it that you set the feed/rev to the pitch req’d and did it that way? If you’re ever disengaging and reversing the spindle I suppose it would work but there’s not the positive indexing that comes with the lead screw. Anyway…

@@matter9 it's ok, small difference in terminology aside, you have understood correctly. I was a Toolmaker not an english professor, but it seems I can still get my message across. Cheers.

No. 🙂

Few hobbyists will ever get to do enough threading to become comfortable, and sometimes a thread relief is not allowed.

​@@phineasj.whoopee3301as a hobbyist an undercut would be way easier than building something as complicated as you have and I can't think of a reason not to undercut

I can't be all things to all people.

The force of resetting the tools pushes the entire carriage forward due to lash in the cross-feed screw. If you watch carefully, the movement you see is actually the entire carriage pushing back. I've since developed a technique for resetting that doesn't push the carriage forward.

@@phineasj.whoopee3301 yeah I saw that movement. There may be an adjustment in the nut on the cross slide. Or replace the nut if its badly worn. But still a cool idea. Im a 39 year machinist and like seeing innovative ideas. I could have used a tool like this for many thousands of parts.

@@martinswiney2192 Some of my employees could have used it .

With long stroke and rapid withdrawal.

There is no room for the spring within the OTS tool holder and to put it under the cover plate would require a much heavier plate and significantly more machining. Basically, cost constraints weigh against a number of possible improvements. I've only once had a chip find its way into the spring, but it went straight down the center and caused no problems.
