Segmented Turning

>I'm just getting started with segmented turning and I was wondering if I should use an Incra 2000 Miter gauge to cut the segments on the table saw or should I use my miter saw?? Also, I want to start off doing a simple solid bowl, how are you folks doing your clamp ups.

>Joe,
I recommend using the TS instead of the Miter Saw. A Miter saw can get dicey, safety wise when working with smaller pieces (just my opinion).
Set your Incra to 15 degrees, cut 12 test segments, and then put them together and see how close you are, the adjust as necessary. This is why most turners that are big into segmenting have a dedicated miter sled that they have fine tuned.
Most segmented turners do not do much clamping. When you glue the segments together, apply glue to one of the segments, take the next segment and rub two of them together to get the excess glue out (you should feel a little wood to wood contact, and then set them on a non-stick surface to set up/dry (I have formica laminate on my workbenches, but you could use a piece of plastic as well.) Once you have pairs glued up, then glue two pairs together, dry, and add a third pair. Once you have 2 half rings, glue them together - you might have to cut or sand them to make sure that they are 180 each.
You can check out the process on Kevin Neeley's website.

>Thanks for the tip Mark, and the web sight. I guess I have a lot of studing to do this week end and some practice too. I have Woodturners Studio but its not doing the math for me I think I'm doing something wrong.

>hey Joe, come to the symposium in Orlando. (if you can) I think there are three guys doing segmented demos. You would get a huge boost there!

>Joe, I'd recommend you use the table saw for cutting segments or, if you want to use up small scraps, a disc sander and a jig.
As for clamp-ups, I gave up doing that years ago based on advice from an old-timer. Put just enough glue on the face of one segment and rub the two segments together until each face is saturated with glue. When it starts to tack up, lay the two segments down on a flat surface (I use a glass plate) and press together by hand for a few seconds. Working in pairs of segments until you have two semicircles. Flatten the side of each semicircle on a disc sander or piece of sandpapaer on a flat surface and join the two semicircles the same way. The same technique works for staves as well as rings.

>I'd like to thank everyone for there input. I've started gathering the channel iron and ordered the screw jack for the segment press, and I tried cutting the 12 segments at 15 degrees on my table saw with my Incra miter gauge and they were all on the money, so I guess I'm off and running.

>Joe - a bowl press may be overkill. I have never used one, some people do, and I think that most don't. If you are not doing segmented full time, your drill press will work for a bowl press.
