Hello Gang-
Im curoius as to what you think about when you have to cut a 42” diameter circle, not from a 4/4 plank but rather a 12/4 Plank. So Ive got this huge blank ready for glue, and than after the glue sets, I got to cut a cirrcle out! Router with trammell?....Chainsaw??? or what about build a platform extension for my bandsaw. Find the center of the furture table top and use a 1/2 emmbedded into the platform.I could then pivot and cut this arch corretc?? what do YOU think?????

BANDSAW. With extension table. I have cut large radius s with extension tables as long as 10-12 ft. Makes life easy. I m not clear on your plight but sounds like you are milling a 42 inch circle from glued up stock. Correct? Just finish nail, glue,screw or whatever to a half sheet of ply. ,locate the ctr. on your extension and have at it. You ll need a drilled hole (1/8 or so) in the ctr. so you can drop a pin in once you have hand fed to your starting mark. Good luck with it. JB

I haven’t had to do this before, but my first thought was to cut it on the bandsaw using an extension. Good luck.

USE YOUR ROUTER WIT A TRAMEL ARM TO CARVE A TRENCH LIKE A 1/4” DEEP ON TOP AND BOTTOM THEN JIG SAW ON THE WASTE SIDE OF THE TRENCH THEN USE A TOP BEARING FLUSH TRIM BIT WIT THE TRENCH AS YOUR GUIDE TO FLUSH IT UP WORST CASE YOUR LEFT WIT A SLIGHT RIDGE IN THE MIDDLE OF EDGE THAT U CAN HAND SAND DOWN

I think cabs has got the best idea.

If you use the band saw, it would only be to cut it rough and then finish up with a template and flush trim. But, 12/4 with a 42” diameter is a beast and would be very difficult to do on the bandsaw.

Well Cabs4less has my vote. I was just trying to beat him to the punch. lol Slow Dell computer.
This is a job made for the router and jig saw. You did not say, but what wood are you using?
I have a lazy susan setup to put under my wood on a job like this. Then the wood turns and you stay solid and have perfect control of the router. Rand

I agree on cabs idea, The wood Im using here is 35 year old black walnut air dried from Tenn. Its very dense.
