Missing from this is the less-scary-than-the-table-saw method, which is using the band saw.

Guess I need to go back and dig up my jig built to the end of using the bandsaw to make dowels.  Think in terms of just holes big enough to push square stock past a moving blade. A clamp here, a clamp there. . . .

Another thing of note is, how long do the dowels need to be?  If trying to make a three footer, that pounding through steel thing isn't going to happen.

Then there is that longer dowels made using table and band saws may not be super smooth. How fast they wood is pushed through and the blade you use will alter the end product.  The end product may have to be sanded.

A long dowel not perfect all along its length may not be an issue, if minor variations in dimensions are unimportant, other than keeping them somewhat close for aesthetic purposes.

When not looking for long dowels, we, generally, are looking for dowels to join pieces, which may include leaving the caps/tops of the dowels visible. Such as using a walnut dowel on a maple stool top and leaving the dowel top visible.

[Leaving now - I think I've confuse myself too, and might start sounding like Ducky. . . .   ;)
