I reakon that might work Mike. Maybe.....start with the oversize circle. Stick an old blade on with double sided tape. Then with a large flush cutting bit with a bearing, adjust hieght so bearings on template blade and cut around it. Then maybe switch to a small flush cutting bit, small enough to get into an out of each of those gullets to finish off. (shrug) What you reakon ?

Jig for cutting teeth......... Have you tried a dentist

Make up a template thats 1/4 of a blade, remembering the ends must match up...
How big do they need them AL?

Al

Use some of the new fangled math thay are learning in school these day to lay out a full scale drawing on your MDF. Use a drill to drill a hole where the gullets should be. them all you have to do is make two cuts in to the drilled hole at 2 different angles to make it look like a tooth. Do a test of small peice first

Why not just cut a triangular shape tooth like a handsaw has.
This shape was common on circular blades before tungsten tips got cheap.
You'd cut them much faster by hand (or with a jigsaw or bandsaw) than you could with a router and you wouldn't even need a jig.

Thanks for the advice fellas,We will give some of them a bit of a go,Regards..............AL PS,Harry........She would like them full size,or as close as we can get them.......AL

I've got an old Dremel 30mm or so dia circular saw blade; only 60 teeth - you can have that...

Cheers!

How big do they want the whole blade I ment?
Just trace around one of your blades and hand cut them with a coping saw... if ya get stuck come around and use me bandsaw... cut 10 at once!

Thanks again for the info fellas.We'll keep your band saw in mind Harry,Regards.........AL
