Default What are "magic donut rings"?

Just purchased an elipse router jig. What are "magic donut rings" and how are they used with this jig which may have loose fitting sliding dovetails?

Welcome to the forum Laurence, it would be to your advantage to complete your profile. Having said that, the only donut rings that I've heard of relate to hairdressing and baking. Where woodwork is concerned we have Doughnut chucks for wood lathes like this one that I made some time ago.

Welcome to the forum, Laurence.

A little bit more information on your "elipse router jig" would be helpful.

Cannot picture an elipse jig and sliding dovetails in the same sentence. Unless you are referring to the small pieces that slide in the cross grooves in an ellipse jig?

hi Arrlay
"magic donut rings"
they are needed to get a true elipse cut with the elipse jig,the oval jig as a built in error that you can't be over come without a donut ring..

the norm when you cut a oval with a router the sides of the are not true,the ends of the oval will be wider than the side wall "parts "

That's what Dunkin' Donuts uses for making glazed donuts.
