Lantern tool posts information

A lantern tool post is a tool. At times it is the best tool for the job. I only use mine on rare occasions. But when I need it I am glad that I have it. I also occasionally use my 4 way. When I need it I am glad that I have it. Rather than spending a godawful amount of money on a commercial QCTP and their tool holders I made a norman style QCTP. It is probably the original QCTP. The patent for the norman tool post was issued in the 1890's I believe. I can't see any benefit that the modern commercial QCTPs have over the normal except that you can buy it and don't have to make it. That's just MHO. Robsig has said he likes learning about and using older technology. If that is the case then he should think about making a norman.

Thanks! I just looked at the Norman design, and it is interesting of course, but as a newbie it is probably beyond my skill level.
Like 'Robsig', I have also said (was it a different thread?) that I enjoy learning about and using older technology. I've only made a couple of things so far with my Craftsman (Atlas 816), but I'm still fine with the lantern, even though it's slow to set up. Especially since I successfully made the rocker washer and rocker 'boat' that were missing, without investing any more $$ at all. And spending a lot of time grinding various 3/16" cutters (right-face, left-face, general purpose, etc.) is also enjoyable at this point. The process helps me learn and appreciate the good/bad.

At the museum where I volunteer, we have 2 much larger lathes (they weigh multiple tons) that I hope to get operational, just as a learning experience. The last time they were used was in the 1970's or 1980's. They both have lantern posts.
I'll report back when I've made some progress.
The first big lathe I'll be working on is described as follows:
Engine lathe, Sidney Tool Co.
19" swing, 146" bed, 96" centers. Overall about 13 feet long.
Flat belt (from overhead line shaft) drives 3-speed spindle cone.
3 speed compound gear box, 8 speed gear change box.

I was an absolutely clueless newby when I made my norman. It was a great learning experience. The only critical dimension is the ID of the hole for the post in the tool holders. It should fit to the post within a couple of thousands so less force is required to clamp the toolholder to the post. When I made the post I made it extra long and used the part I cut off to test the fit on the hole in the tool holder.

If I could make it, you can make it too.
