Default Please rescue me...

...from this morass.
I've searched this forum, Googled for an answer and wandered through Youtube, all to no avail.
I have an insatiable desire to inlay an oval of non standard dimensions using an inlay kit.
So, a template needs to be made.
For the life of me, I cannot figure out how to determine the offsets needed to construct said template in order to yield a 4.5" x 6.5" oval and corresponding cavity.
Somebody, somewhere must understand this arcane alchemy and can explain it in small, simple words for me....PLEASE.
I would be eternally grateful and will sing your praises to one and all.

Found these

If you're into Sketchop https://help.sketchup.com/pl/article/3000084

And here is a long-winded video showing step-by-step

I did a Google sketch - how to draw an oval - lots of hits.

Gene,

If you are using an inlay kit, you don't have to figure any offsets. All you need is a master the exact size and shape of the piece you are in laying. You use that without the bushing to make the template for the inlay socket. You pop the bushing on and route out the pocket. The bushing will take care of all the math.

Basically all it is doing is offsetting for the width of the router bit.

Gene if I am working from a template I do it like Doug (kp91) does it but if I am cutting an oval out I use an oval cutting jig I made.

Measure once cut twice and it's still to short.

Gene, Microsoft Word has an Art feature that automatically draws circles, ovals, squares and rectangles. Make a document with small margins and draw an oval the size you want, print it and transfer the image to the template material. Cut it out, sand out the edges and you have it.

The more I do, the less I accomplish.

I've always used a "mat" cutter to create patterns for ovals. They can be found at craft supply or picture frame shops. Cheap & simple without all of the math.

"Mat cutters" available at craft shops (for picture frames) is what I've always used for oval patterns. Easy & no math. The cutter & a piece of poster board is all you need.
