I've been a member here for a couple years and have enjoyed seeing all the great ideas shared. I received a lathe for Christmas this last year and have been enjoying getting back into woodworking. I've had my BT3000 since 1996 or so and has been a great machine over that time period. With the lathe though, I wanted to try making some segmented bowls. Without ever getting the double miter add on, I've always thought I could just make a miter slot for jigs. Then it dawned on me... Why not just use the sliding table and attach the jig to the table using the same pin holes the table fence uses. I didn't have any dowels that size so I turned a couple using a chunk of scrap walnut from a log. Attached them built the rest of the jig and made some tests. The ultimate test was the bowl which I'm pretty happy with. Just wanted to share this as I hadn't seen this same configuration used. (Doesn't mean it wasn't done before, I just hadn't seen it.)

WOW, that looks great. Great idea and simple, (but precise). Thanks for sharing this.
I too want/need a segmenting sled. I hadn't thought of using the miter sled.
One caveat is that the miter sled must be "tuned" or there will be error in it. I have two miter sleds, and one is in constant need of being adjusted but the other has been dead on since I bought it in 2000. That issue is what divides most people. If one has a great sliding table, then this is a great machine; if it is one that needs constant adjustment then this is just a cheap saw. I have one SMT that could use a jig like yours.
Thanks for posting the picts.Hank Lee
Experience is what you get when you don't get what you wanted! -
The segmenting jig is set up to make the angle cut on one side/end, and then do a corresponding angle cut on the other side/end.
Here are some links to segment making - go down though the links and you can see a progression of how "segment cuts" make up a bowl:
If a cut is as much as 1/8th of a degree off, then there can be space in some places where segments meet. If one segment is 1/32 longer than another segment, then problems can arise. Segments have to be dead on. And making repetitive cuts the same length and angle are a necessity. Difficult at first but gets easier with practice and experience. More easy for some than for others.Last edited by leehljp; 09-12-2018, 12:05 PM.Hank Lee
