Oval Tray Jig

I made an oval tray a while back and lots of people liked it, myself included. I am now planning to make several more and needed to come up with a better way to deal with the installation of a floating bottom in an oval frame.

This simple jig, based on one of those HF trim routers I like so much, works perfectly and only took a couple of hours to design / build. You can still adjust the depth of cut and the height above base is somewhat adjustable. For my purposes I wanted 3/4” deep tray walls so it is set for that. My tray bases will be 1/4” material, veneered on both sides so it will take one cut as-is and one cut with a 1/16” shim. It has a web on the bottom to clamp in any vice.

The curved piece on the face of the router is attached with double sided tape but I may buy another trim router to dedicate to this (~$18 this week) and epoxy it on if I really like the jig.

Nothing special or new here I suspect, maybe just a cheap solution to a tricky problem.

Thanks for looking



When I first made this jig I was envisioning sharp corners inside the tray. Each side would be done separately so I didn’t have to get into the corners. However I design as I go and came up with a way to use radius corners which led to this modification.

The router base assembly is too wide for this application so it is removed and the guide becomes merely a “pin”. Without the thick curved piece on the base, this one doesn’t need to be extended as far as it is but rather than rebuild the jig, I used it as-is and it was fine. If I did it again I would make the clamp closer and the extended part of the bit shorter. Beyond that the photos speak for themselves.

You’ll have to wait to see the bottoms that are going in these trays. What you do see is a 1/8” template that will be used to cut the bottom panels.

Thanks for looking again

Hmm. Thinking inside the box. Good idea, even if they keep telling us to do the opposite !

Paul, great design on the jig. However, I think you have erred in the link to your projects page. When I clicked on “oval tray” I got your storage unit project instead. Your great tray is just below it. You may want to edit the post to correct this. It is difficult to follow how the jig works without the finished product in mind. I do like the jig. Thanks for sharing it with us.

You never cease to amaze us with your unending creativity in problem-solving. Thanks for another great idea!


P.S. I’ve had the HF trim router for several years now (mine’s orange) but can’t say that I like it. The clear plastic base is so flimsy on mine that I have a hard time getting it tight enough to hold the depth of cut. Is yours newer and maybe improved?
