Oval Walnut Frame

[Tim Hunter]

Getting ready to shape another Oval mirror frame on my elliptical turning machine. Think of it as a very over-sized ornamental process.

A few short videos of the process are available here: https://www.youtube.com/channel/UCq5t3yd4D5TkDop44odfj7w

Pretty cool process. Nice to see how it's done!

I see how the base moves in an elliptical path.

I think I once asked how the router is positioned for successive contouring cuts. I seem to recall you saying it was manually positioned, but I might be wrong about that.

In one of your videos I see a top view showing a threaded rod rotating. Is that a feed mechanism for the router? Can you show us the whole machine, or would you prefer not to?

Here’s an overall image of the set-up. All adjustments are manual.

Thanks for the picture Tim.

Judging from your machine and things I see in the background of the picture it appears you're a scrounger of various things to apply to building your equipment. Good to see, scrounging and adapting machinery to woodturning innovation is something we see too little of on this forum.

BTW, what is that bit shown in the router, it looks pretty aggressive. Nice to see it climb cutting. That's something that everyone should be using with their threading jigs, but my guess is 95% of threading jig users don't know what a climb cut is.

Yes, I build, restore, and modify equipment to suit my needs. My lathes are great examples. I’m not a name-dropping shiny tool owner. The only machine in my extensive shop that I ever bought new is a chop saw. The bit shown is a Whiteside spoil-board cutter that I use for facing. I do primarily climb-cut on my oval machine, and conventional for some finishing passes (the table can rotate both ways with variable speed - thus the SCR drive).
