Under the heading “You never know unless you ask”….

Would anyone consider turning some knobs for me?  (not free)

I am making two amplifiers and I need knobs for volume and selection.  Two 28mm dia. and four 36mm dia.  A slight crown would be nice.  I had a larger knob made for my tube amp a couple years back but the shop that made it is too busy with large orders.

I’m flexible on size and material as I don’t know if it’s possible to make them in the diameters I drew.  I’ll also need a hole for the potentiometer shaft and one for the set screw.

Turn them on your router table.

Not sure how to do that.
Thought about a trying a router bushing and template.
But it won't come close to the finish/feel when it's off a lathe.
 
If you have a hole saw and some threaded rod - and are willing to have a dark plug in the center you can make something like this for a router table.  I actually have this jig and have done a hundred or so pens on my router table.  Let your imagination go wild - you rock at that.

And sooo....  I began to ponder other solutions....
I came up with two large wood thumbwheels connected to timing pulleys to control the volume.  Kinda 1940's retro.

Drill 1/4" hole partially into a square block of wood.
Drill and tap hole for a grub screw.
Trim block to knob size on bandsaw.
Fit a short 1/4" shaft to knob, fit shaft in drill, hold against sander -> finished knob (with a bit of practice).
 
I have a lathe and would love to give it a try.  No charge, unless I have to buy the wood.  My only source for small stuff is a sort-of-local Woodcraft.  PM me with the specs if you're interested.

The router methods some have suggested may have the grain running the wrong way for the best look.

Cheers,
Crox

Here's his email from a minute ago.  Unbelievable [cool]

"Luke,

I grabbed a walnut offcut, cut out a 35 X 25 disk, stuck it to a 3/8 plywood disk, screwed the two to another plywood disk and mounted it to my faceplate. I turned the cylinder to 30 mm, using the tailstock for support:

Then I backed off the tailstock, moved the tool rest athwartships, and gouged and scraped the face to 20 mm, with a bit of a dome. Piece of cake.

[attachimg=4]

Sanded it 120-220-320, right on the lathe. Too easy.

Turners' goop shines it up.

Pop it off the plywood backer, and Bob's your uncle (below).

I made a second one, just to see if I could do it, and it came out pretty close. They're really quick to make after the first setup. "

Wow...

You gotta love when you run into someone that takes it upon themself to do something for another just to be nice.

Rare these days, great to see!
 
Day late or would have been able to help you out.  Surprised there's not more turners on here, maybe if festool made a lathe? [tongue] haha, turning is a lot of fun, people should def give it a try if you haven't.
 
[member=17405]Crox G[/member], the knobs look very nice. Thanks for helping Luke out.

Tom
 
You do beautiful things. And I see that you are doing well. Congratulations.
