I want to try segmented turning and I have some obstacles #1 In the videos after the ring has been glued and dried the ring is put through a thickness planer. I don't have a planer or any other tool like that is there another way.
#2in the video on making the sled with adjustable fences the bolt arc for the adjustment for the fence is routed is there away to do this with out routing, I don't have a router thanks.

You shouldn't be using a planer … glued up rings have a tendency to EXPLODE when run through planers. A drum or disk sander is a better option and you can make your own disk sander to attach to your lathe. Attach a plywood disk to a face plate, then attach a pressure sensitive sanding disc (from your local big box store). Keep the speed down (under 600rpm) and turn on your dust collector. Here's a link to a Fine Woodworking article: https://www.finewoodworking.com/2011/07/19/turn-your-lathe-into-a-disk-sander

i have a sanding disc for my lathe, but no dust collector. should the rings be fastened to a board or can you sand them as is

Depends on the thickness of the ring. If you rings are 1/2" or more thick, just hold onto the ring … flatten one side on the sanding disk, glue onto the stack on your lathe, then sand the other side with a sanding board when the glue dries.

If all your segments are the exact same thickness, some wax paper on either side and use a caul top and bottom to clamp them into alignment, I only use blue painters tape to hold the blocks together for glue up. Try not to use excessive glue and ring should only need a quick scrape or light sanding.

I have a planer and router, but I sand rings just as The Dane explained. All you need is a piece of plywood with a block glued in the middle. This can go right in your chuck or set it up to be screwed to a face plate, depending how you are equipped. I use my shop vac to handle sanding dust.

A 8" or 12" disc sander will do the job, but you get sawdust all over. It takes time but you could sand the layers flat with sand paper attached to a flat surface, on the workbench. I've seen videos to the method which mike02719 discribes. I'm currently using a 4×36 bench sander. run it on the belt sander to get it somewhat flat, then switch to a 12" disc sander to minimize the wading dust. Does alright that way. But I plan to use a dedicated 10" drum sander in the near future.

For the routed slot. You could mark it out with a pencil and chisel out the slot. Or Mark out the slot with a pencil then drill out a bunch of holes, then finish with saw, chisel or file. May take a little time this way to get a Wedgie Sled, but will work.

Here's a couple ideas for a segmented cutting jig. 1st one make a sled for tablesaw, measure your angle and glue down the wood for dedicated cutting angle for 16 or 20 peices a layer, and use a disc sander to flatten the halves the glue up the two halves for the layer.

2nd one is to use T-tracks instead of arch slot holes. This style for a wegie sled.
