These bowls or serving trays are routed with the CMT Bowl & Tray System Bit Set. For the round serving tray, I used two pieces of 8/4 walnut on the outside, two 4/4 strips of curly maple, and then a 8/4 hard maple inside. After the blank was glued and surfaced. I drew the pattern onto the top of the blank and used a forstner bit in my drill press to remove most of the waste. After most of the waste was removed I double sided taped the template to the to and routed the tray shape. To make the rounded external edge, I made a small circle that would snuggle fit in the dip portion of the tray and used a router and trammel to define the outside edge with a half inch straight bit. I then bandsawed close to the edge and cleaned up the bowl circumference with a bunch of passes with different patten bits in my router table. I sanded the interior and exterior of the tray with lots of hand sanding and then used a round-over bit in my router table to ease all edges. I didn’t have any tearout that was not easily removed.
What I would do different is to define the circumference of the bowl with the router and trammel before removing the waste so that I had a better center point that didn’t wobble. Then finish removing the waste and routing the interior of the tray before finishing the exterior of the tray.
The trays on the right are hard maple on the bottoms and purple heart on the top. I took my hand at making my own templates so that I could affix the template to the top of the bowl and routing the inside and outside of the bowl without moving the template. I followed essentially the same procedure as before.
On these bowls I had lots of tear out in both the purple heart and the hard maple, from both the round-over and the straight pattern bits. You can see a hint of the tearout in the picture. I was so pissed I couldn’t see straight by the time I was done, and most of the tear out wasn’t able to be removed without scrapping the project. What did I do wrong? Any suggestions would be appreciated.
