Mill a circle - Paulc - 10-17-2019

If one doesn't have a rotary table, how would you mill the  circumference of a circular piece with a small stem (think banjo shape)?

Lots of facets... https://www.youtube.com/watch?v=hTj6LC6agrg

A mill with a digital readout that has an arc function will work too.

Looks good. Have to give it a try.
Thanks for the tip.

It could also be accomplished using a fixture with some stop pins assuming one could have a pin hole in the center of the circle. Just make sure you conventional mill, not climb mill.

You are looking at this all wrong. You NEED a rotary table. Use this opportunity to buy yourself a new (or used) rotary table.

You're really making it hard to not get a rotary table.

But rleete is correct.  How do you think I ended up with a 24 X 48 X 12ft shop packed full of tools? Big Grin Big Grin Big Grin Big Grin 

And yes I have a rotary table and an indexer.

Keep in mind that a rotary table has more uses than just cutting circles and arcs. They are also useful for indexing/dividing as well.

Just added a HT furnace to my "need" list. Big Grin

You guys are quite persuasive Big Grin .
Finally broke down and ordered a rotary table.

Now just have to figure out how to use it!  Blush
