Chuck Question

Hello

Was looking on google books and found this. https://books.google.no/books?id=nCcDAAAAMBAJ&hl=no on page 181. There is a drawing of a chuck this guy used for several thousands pipe, but would it be anything to use today?

Theoretically, but why use dated tooling when there is better. Try Trent Rudat, he makes fantastic two jaw chucks.

"Can I use it?" and "Is it any good?" are very different questions.

That looks to be a slight modification of a 4 jaw chuck. Easier to buy a wood-turning chuck like a Oneway and get some jaws for it and screw them on.

Thanks for answers! I am not that good in English, but what I meant was, would it be safe to use in your opinion?

With any chuck, the biggest thing is probably if you can get the block nice and square so it sits well. That makes it safe. If it's lumpy, it's hard to get ahold of.

I checked out your link, very entertaining. I marvel that you found this article.
I note that it is the November 1941 issue, and that the lathe was described as 'ancient' 75 years ago.
The basic mechanism used to turn the stummel is the same as pipe turners use today but the face plate used is different and appears to be somewhat less secure than the tower jaws on a 4 jaw chuck used these days.
Of course a chuck and tower jaws can set you back hundreds of dollars, while the modified face plate could cost considerably less if you have the materials and machining skills to build it.
If you go that route, I would recommend that you wear a face shield while using such a mechanism, because I can almost guarantee that you will have a stummel come loose and fly off during turning.
It will work and if obtaining a modern chuck and tower jaws is beyond your means at this time, then be careful with it.
Good luck

I made the article into a PDF to make it easier to use.

Instead of making a chuck, convert the same thing to a vise for the drill press. Then use the drill press as a mill to bore out the stummel and drill the airway. Mounted in a 2 way cross slide vise and you have a basic milling machine setup. That way you don't have to wonder when the blank will break loose and slap you upside the head.

As George will attest you need a really good drill press to do a good work on drilling pipes, most have too much slop in the spindle and too little travel.

True, but sometimes the sloppy drill press is because of operator ignorance.

A tune up of the drill press might help. http://www.rvplane.com/pdf/drill_press_tune-up.pdf

It would be a pretty sad drill press that had too much slop in the spindle to drill a hole in wood.

There's a big difference between drilling a hole and drilling an accurate hole. It's the mortise hole and face really that I am talking about, chamber and airway not so important.

This set up here viewtopic.php?f=9&t=11115 Is just another version of the chuck/vise that is in the quoted article.

A drill press is a vertical lathe without a tool rest, and a lathe is a horizontal drill press with a tool rest.
