Does anyone have a home-made jig for cutting small diameter circles? (Smaller than the diameter of the base itself).

I have a couple trammels built from ShopNotes plans, but none of them have provisions for very small circles.

Thanks.

take a look at the sketch and figure out your sizes and enjoy. The view is from the bottom, the hole is for the "pin", the two matching slots are for the mount screws (flat heads). This of course may not work on your router..... and yes it is for a plunge router.

Most excellent! This was just the piece of info I needed, I have a few pieces of HDPE left over from making my router table -- one of those will work perfect for this jig.

Thanks again.

I have enclosed my circle cutting jig that can be adjusted from the top with the two screws that is used to hold the side fence attachment.( This is the side fence attachment for Makita 3612 or the Hitachi 12v) This certainly is easier to adjust. I use it all the time to rout circles from 30-40mm in diameter depending on the cutter used. It is also adjustable to increase the size of the circle simply by repositioning the "Pin"
I have also produced another jig that does NOT require the side fence attachment as illustrated.

Tom,
I have an M12V so that looks like a pretty handy solution also.

Thanks much.
