How to Turn a Honeycomb Resin Bowl


I recently had the pleasure of working with a South African resin artist named Ahron Gropper on a long-distance collaboration. After seeing a beautiful bowl he had created that incorporated a synthetic honeycomb element embedded into the bottom of the bowl, I contacted him to see if he would be willing to create a similar resin bowl blank and send it to me so that I could turn it on my lathe, and he graciously agreed. In this article, I’ll share some highlights from the process, as well as a few tips for turning your own wood and resin bowl.


Preparing the Blank



Cut Pieces of Honeycomb Bowl

1. Lay out and cut a river pattern in a round bowl blank.

Draw a gentle curved shape that cuts through the middle of the blank and follow the lines to cut out the shape using a bandsaw.



Glue Pieces of Honeycomb Bowl

2. Attach your pieces to a non-stick surface.

Set the blank onto a non-stick surface—Ahron used food grade HDPE (high density polyurethane)—and fix the outside pieces in place with hot glue, using the middle piece to space them appropriately. Once the outside pieces are fixed, remove the middle piece. Then, use hot glue to seal the edges of the outside pieces to the work surface to prevent resin from seeping underneath the wood pieces.



Cut Honeycomb Insert

3. Cut the honeycomb insert.

Using the curved middle piece of wood as a template, cut a section of honeycomb to fit snugly between the wooden pieces. Ahron used a bandsaw to cut the honeycomb.



Position Honeycomb Insert

4. Tuck the honeycomb in place and seal the ends.

Carefully insert the honeycomb into position between the wood pieces, and trim away any excess honeycomb material from each end.

Add Plastic and Seal

5. Level the blank and seal the ends.

Carefully ensure that the blank is level, adding shims underneath as needed. This will enable you to fill the void completely with resin. Seal the ends of the honeycomb section using a piece of plastic or PVC and some hot glue. This will serve as a form to keep the resin in place while it cures.



Mix Honeycomb Resin

6. Mix your casting resin and add dye.

Ahron used a resin product called Art Expressions South Africa to fill the honeycomb section and added a couple drops of dye to color it. Other brands of casting resin should work fine here as well.

Pour and Cure Honeycomb Resin

7. Carefully pour your resin and let it cure.

Carefully fill the central cavity with resin up to the top of the form. Make sure you allow the resin to fully cure before mounting on a lathe. This can take quite a bit of patience and cure time will depend on the type of resin you use.


Turning the Bowl


Once your resin has fully cured, turning a resin and wood bowl is much like turning a normal wooden bowl, with just a couple differences.




Turning Honeycomb Bowl

8. Negative rake.

I find that a carbide negative rake scraper works best for turning resin. I use the Easy Wood negative rake round carbide insert which pops right onto my existing Easy Wood handle. Compared to using traditional turning tools, I find that I get a cleaner cut and less of a tendency for the tool to catch.



Sanding Honeycomb Bowl

9. More scraping, less sanding.

Get the surface as smooth as possible with the lathe tool. You’ll want to avoid getting deep scratches in the resin, so it works best to get the surface as smooth as possible with your negative rake scraper before moving to the sanding stage, that way you can start with a higher grit. I started with a 180-grit abrasive and moved up to 600-grit.



Finishing Honeycomb Bowl

10. Finish.

After you’ve shaped the bowl to your liking, it can be finished with a coat of polyurethane to bring out the luster of the wood and resin. I finished this bowl with a few coats of Minwax wipe-on polyurethane across both the wood and the resin.
