Wink Round TurnTables

Check out the swivel bases. Painters use these all the time; easy to use, screw use scrap wood, say 12" x 12" on both sides, bolt one side down to table or saw horses and spin the "table", not the router.

This is much safer also. AND you can use it for painting later on………

Can send a pic for clearer image.

Oh and spin the top sheet, yeah I guess that would work. The thin, 12" turntable work nice ~ no play at all, it has ball bearings.

Running in router circles works, but the cord gets tangled up – it’s all good/easy with a little practice.

Default btw....How to measure?

How to measure?

Example: say you want a 6 hole, measure 3 from the outside of the bit to the center of the pivot (which could be a simple nail or screw).

It is important to measure dead center of the hole, even if that seems insignificant. Holes too big or too small are not much fun when building speakers.

had to come up with a circle router, and fast
and I decided it had to be adjustable
turned out to be exstremely simple

I bet anyone can find the materials within 5 minutes
and besides, when changing router bits, adjustment changes

Not adjustable??? on the contrary infinitely adjustable. The pin can go anywhere on the board. It's an old picture, now I like to use the drill bit as the pin, as it's the perfect size. measure, drill hole in swivel plate, align hole with center dot,drill center, leave drill bit set into wood to be routed. I tend to use a starter hole for the router bit as I don't like plunge routers.

Sorry, no router for you.

well, I dont have a workshop, and rarely repeats the same routing
but if I were, I would definateky use a fixed jig like your
much better for repeating the same routing job
its a more 'professional' way

but my routing is always different from yesterday

That's a good set up, my Makita came with something like that (with the bars) so all I needed to do was drill a hole in a alum support (square block at the end).

Its a little easier and safer if you "swing" the baffle board, vs. swinging the router. You can get fancy and buy/find a flat ball bearing (round table) or simply put two work-boards together with a nail in the center.

Perfect circles are easy to cut, easier than square; Imo.

Don't cut too deep in one pass......Wear eye protection! Router Bits can snap, and/or worse They spin around 25,000Rpm, depending on the router.
