I need to make a dowel just under 0.75” to fit into a 0.75” holdfast hole.

A 9-mm roundover bit produces a dowel 0.709 inches in diameter, which is perfect for my holdfast holes.

Does anyone make a 9-mm roundover bit with a 1/4-inch or 1/2-inch shank? (I’ve Googled, but had no success finding one.)

If you don’t have a lathe, you could buy a 3/4” dowel and chuck pieces of it in the DP and sand it down. But it will probably be a little undersized anyway so might work just as you buy it.

I’ve always just bought 3/4” dowels. They run small, and you need to use something to make them tight. I use the Paul Sellers method of inserting a bent lawn stake for marking sprinklers.

Do you know you can make a dowel on the table saw with a simple jig?

If I only needed a couple I’d probably try scraping down off the shelf 3/4” dowel.

An older way for making (short) dowels was to drive a slightly over size piece of wood through a hole drilled in a thick steel plate. Taper the end of blank down to fit the whole and then pound it through the hole.

I do not have a lathe.
The dowels I buy are too large for my holdfast holes.
I want to make 22 bench dogs, so sanding them individually is impractical.
A dowel plate will be hard to find or manufacture for making dowels just under 3/4”.
Thanks for the ideas.

Would a 11/32” round over the fit too sloppy? (would require a router table w/fence)

You could also start with a bigger round dowel and do the same thing without the pvc pipe.
Just be carefull.

What bit are you using to drill the holes? I just went out and measured with a micrometer. My off the shelf dowels are dead on 3/4” and all the holes drilled in my bench with an auger bit are 1/64th over.
