What do you think about this idea for epoxy feature ring

I was trying to come up with with a way to fabricate an epoxy filled open segment feature ring which minimized wasted epoxy.
I have not tried this yet, but was looking for feedback on problems it might create or if it would even work.
I have a CNC router.
The plan is to create and glue a segmented ring.
Then use the CNC router to create pockets within each segment with the bottom of the pocket being very thin.
Fill with epoxy, then after curing, run it throuch the sander (would a planer work?) to remove the bottom material and flatten both top and bottom.
From there, glue up the remaining rings and turn as normal.

All comments are welcome, especially the ones that might keep me from huriting myself

This would be the ring with pockets.

Interesting idea. I have seen bowls with epoxy resin incorporated in the design.

Here is some thoughts for your featured ring since you have a CNC machine:
- Option 1: use a solid piece of wood or glued up laminate to the thickness of the featured ring and have the CNC mill out from the solid piece of wood to produce the image you posted. The pockets the cnc would cut out would provide the segment look.
- Option 2: build a closed segment ring and mill out the gaps leaving a thin bottom.

As far as removing the solid bottom of the ring I would use a sander. Some have not had that good of luck running epoxy boards/rings through a planer. The risk of chip out is there.

once flattened the featured epoxy ring could be mounted on the bowl and then use the lathe to remove the inside and outside diameter solid wood.
 
Thanks for the input. I will go with a glued up ring so there is no end grain.
I just ordered a presure pot.
On a side note, wht is a good coloring agent for epoxy?
 
There are many powder and liquid dyes for epoxy resin. Members of my woodclub tend to purchase off of Amazon. Can't say one brand is better than another.

imo, for the small pour in the routed pockets I do not believe you would need to use a pressure chamber. As the resin dries if bubbles emerge you can use a heat gun or torch to heat up the resin just enough to have to bubbles disappear.

Good luck with your project.
 
I have never tried using apoxy in a seg bowl as the segs. i have not read any of the others say they have either, my question is will the glue hold the apoxy seg un the presure of turning

That is a very good question. That is the reason I was going to esentially make a wood mold ring with voids to hold the epoxy.
We use epoxy all the time as an adhesive (ie. epoxy adheres to wood). But I too question the strength of the bond between cured epoxy and glue. but I have seen videos of segmented glue-up that were then filled with epoxy before turning. But hey...there is only on way to find out....

Wood glue will not give a good bond with epoxy. You must use epoxy to secure epoxy to wood.
I have seen full epoxy segments used before. How they actually make the segments, I didn't really pay attention to.

There is a product sold by Craftsupplies in their Woodturners catalog that I have used often. Its called InLace (inlay) Its an acrylic epoxy and comes in a lot of colors. What I did was to create my Indvidual segments with voids in them, such as drilled or open segments, then poured the liquid InLace into them and allowed it to cure. You can then mount and turn your rings on the lathe. However, word of caution, in the picture posted above, when you turn off the inside and outside wood, exposing the epoxy note that the epoxy or InLace does not adhere well to the wood and the epoxy chunks can come flying out while turning. This I know from experience. I solved my situation by applying thin CA glue along the edges of the cured InLace (epoxy plugs) which seems to then bond well and prevent the movement of each plug. Good luck, I hope this works for you.

I wanted a ring with no lines so i went with this bought silicone pans Worked great

That looks like a great idea for a ring. Did you use 2 of those and filled the space between the two, or did you just use one and then used something to fill up the middle of the pan?
 
Please tell us where to buy these rings and a description.

If using Inlace, believe it when they say use in a well ventilated area. I would say only outside is enough ventilation.
 
just a thought but I have made segments and inserted them into wood rings before. what I did was make a mold for the epoxy about the size that matches your wood pieces that you will be cutting on your segment sled. Used deep pour epoxy and you will not need a pressure pot. after the epoxy sets cut out the segments on your segmenting sled just as you would do with the wood. this has worked well for me.
