Good work You make!!! Actually the tool-post like You make is planted on any (without except) in Russia (one-time Soviet) manufactured universal lathe.
Boring bars and grooving tools? you need an adjustable plate with a indexing ball in it and a mating divot on the tool post. set the compound for your job and then set the toolpost for cut off. That would be something worth patenting.
see where i work i use a capstan lathe with a turret which also has a turret tool post, but the post is seezed up. anywhere i could get a new one so my boss can sdort it out???
A nub left is common, when you don't have the tool on center. You try and explain it away as being "common", remove with a second chucking?? Why would you "waste" a quick change toolpost on the rear of the cross slide? If you were going to have a dedicated rear parting blade holder, it would be in a rigid block.
The piece that is parted off will always have a very small nub left on it from the parting opperation because the small bit of material holding the piece part to the main piece of stock is not strong enough to allow the parting tool to cleanly cut all the way to center. Of course the stock that is held in the chuck will be able to be cleanly finished. The quick change tool holder in the video is not wasted as it saves time by not having to change tool holders and is always setup.
Nice Video. So essentially this is just a nicer 4-way turret tool post? Aside from the indexing to 30 deg increments what is the main difference from my regular 4-way? All I use these days is my QCTP. How does your tool post have an advantage to the QCTP? Thanks
I can't answer the first question as you have not said what type of regular 4-way tool post you have.
The Turret Tool Post in my video can have up to 4 tools mounted simultaneously and each needs only to be rotated into cutting position and the turret locked down. The Turret Tool Post excells at production work. The Turret Tool Post can be indexed in increments of either 15 or 30 degrees and is absolutely repeatable.
This lathe is a Logan 11". Yes I did build a new double tool post cross slide of my own design and I am very happy with it and would not go back to the original.
The Turret Tool Post is sized correctly for your machine when you build it. You need to determine what size tool bit you will use and then all cutting tips are on lathe centerline. If you resharpen the top of a tool bit you need to return the tool bit back up to lathe centerline by shimming or adjusting jack screws that you install when building the tool post.
I agree, but it is a small inconvenience to trade for speedy tool changes and absolute repeatabilty, especially on production work, even short production work. Some builders have placed set screws under the tool for adjustability and to eliminate packing.

I do not have ready made turret tool posts for sale. I just sell the plans to build your own turret tool post and they are available at.
