Question Best way to make 3.5 inch mini frisbee shaped discs.

I am wondering how to produce small wood discs that have a rounded profile edge and also have a recessed underside. what would be the most efficient way to produce multiples?

If I were doing it ... between centers, I'd turn a long blank into a cylinder the correct diameter for the disks. At one end, I'd make a tenon that can be gripped tight in my chuck.

Mount the cylinder in the chuck by the tenon. Bring the tailstock up for support and to ensure it's square in the chuck before clamping down fully.

Remove the tailstock. Turn the profile of the underside of the frisbee (the recess) into the end of the cylinder, then start a cove to form the beginning of the top. Part that piece off and set it aside.

Turn another recess into the end of the cylinder. Part off another disk. Continue the entire length of the cylinder -- until finally turn a tenon (that will function as a jam-chuck) on the stub that remains in the jaws. Push the recess of a disk onto the jam-chuck, now you can finish the top.

Pop that disk off, jam the next disk on, finish it ... lather, rinse, repeat.

You didn't say so I am going to make the assumption these are from 1X4. I would mount between centers, round, and turn a small tenon and shape the outside. Reverse in a chuck and shape the underside with the slight hollow. Then use a friction chuck and reverse again to remove most of the tenon, sanding off the small remainder.

I'd do it all with a router with a bowl cutter, using an MDF pattern.

Vacuum chuck. Turn the inside, reverse on a vacuum chuck and turn the outside. You can't be aggressive doing this because 3 1/2" isn't that much space for vacuum which is 14lbs per square inch maxium. However I bring up the tailstock for the roughing part and then pull it away for the finish cuts.

Personally I would like more info. Never like getting a 1st time poster asking questions with little detail but it always happens. I'm assuming you have a lathe but how much experience do you have? What chucks and tools? What size disk and what type of wood?

I/We usually like to get a intro from the new guys first so we can welcome them to the forum.

Gene he posted in the woodturning section so I'm assuming he has a Lathe. How much knowldge and experience is a question since he is a new guy.

Good advice sawdust. Personally I have trouble making duplicates of anything. I'm a original man myself everyone different.

Don't they have duplicators for the lathe.


As for everyone else, A lot of good ideas but what if this guy is new at it and is more confused now then before.

Ahhh..so. Richard. I use the "New Posts" button and didn't catch which forum.
Still, If I wanted identical duplicates, I'd still use a router and template.

Yes very confused... the router idea is more attractive since I don't have a lathe. What is a bowl cutter? I have collected many tools in the last 40 years ( i'm 64) don't have bandsaw or lathe. I do have shaper and routers, mostly work in cabinetry and remodels of homes. No lathe experience. Bruce

I also assumed you had a lathe. The best way to make rounded discs is with a router. make one jig to cut the outside, and one jig to round out the inside. the use a V block on a router table to round over the edges.
