The glassworking lathe described here is designed around TAIG metalworking lathe kit components. Topics relevant to the art and craft of making Custom Game Calls not specific to a particular call making area such as finishing, tooling, lathes, and other items.
But there are distinct advantages to using a four-jaw chuck (which is generally assumed, contrariwise, to have independently-adjustable jaws), and though a three-jaw chuck is nice to have for convenience and for use with hexagonal stock, most machinists find the four-jaw chuck to be more versatile and useful in the long term. This table is adapted from a list by Bruce Simpson, as quoted on Frank Hoose’s excellent lathe-work site.
If you are going to spend the cash on a decent self centering chuck it might as well have six jaws because it wont be much more than a 3 or 4 jaw and they don’t mar thin tube and soft materials as badly. As well, generally only companies who actually know what they are doing make six jaw chucks so you won’t get trash. Few woodturners have a problem with mounting a bowl blank on the lathe to turn a bowl or a platter. This self centering, 3 jaw micro chuck is ideal for holding small projects from the inside or outside.
The Longworth chuck was developed in the late 1980’s by Leslie Douglas Longworth of the Hunter Valley Woodturners in Australia.

I spent over 2 hours on my metal lathe turning them from bolts however they are a perfect fit. Better yet, if you turn a tenon on the faceplate you could simply chuck it instead of threading it on to the lathe’s spindle.
However, one thing to keep in mind is that these types of chucks are primarily used to finish the bottom of a project and not for any heavy turning.
For precision work on a metal lathe you generally see only 4 jaw independent and 6 jaw chucks. An idea for another inexpensive approach to the headstocks and chucks - lathe collet spin index fixtures.
Building nonelectrical woodshop tools, including a basic brace, auger bits and expensive garden and woodworking implements, use homemade hand tools. I started with two plywood disks sized to the maximum over bed turning capacity of my lathe.
Because of the size and weight of the chuck, and also because I am just using it to finish off a bottom of a piece I usually use it with a speed of between 500 and 600 rpms, though I have had it as high as 750 rpms.
Very good article by the way, a little hidden gem in the midst of a google search for ‘homemade chuck’!

A fellow turning club member is wanting to get together with me to build a couple Longworth chucks so maybe we’ll find some suitably flat material. There are 4 jaw scroll (what the trade calls a self centering) chucks.  Most wood lathes come with them. Once the faceplate is attached to the disks put it on your lathe and turn the disks perfectly round, removing as little wood as possible to maximize the size of the chuck. Then I tighten the wing-nuts and follow this up with more tightening using a wrench when the chuck is mounted on the lathe. If you want to use MDF for the flatness, try gluing a piece of thin BB ply to it to keep it from disintegrating at higher lathe speeds. The faceplate will be permanent so you need to get one specifically for the Longworth chuck.
