RE: [rsa] what to look for in a drill press
- Post tool may have wood lathes. There is/was one around South Van Ness and
Division. Sears too, but I think the closest is down here in San Bruno.
Maybe Orchard Hardware since they carry a lot of the Sears Craftsman tools
I discovered this place on the web a few months ago but haven't dragged
myself across the bay to check it out:
Looks like a great place to burn out a credit card.
A lot of wood turning activity is focused on making pens and bowls. If you
Google for "wood turning pen" and similar combinations you will find lots of
information. Some of that may help with your wheels.
If I'm understanding your question about the grooves, the formal method is a
milling machine with a rotary table. A lower cost option might be a Dremel
tool in one of their drill press mounts. A turntable would be nice, but you
could probably make a simple jig. Once you have cut the first groove cut
you can start to add pins to your jig to maintain uniform spacing.
Cutting metal is very cool, but making wood chips is pretty nice too and
smells better. Its definitely lower cost and safer. Home Depot and Lowes
sell some hardwood in small pieces. Add a little stain and some brass
hardware and you could compete for a beauty prize too.

Depot doesn't seem to have any. You know, every time I start thinking
about doing things in metal I end up just doing them in wood. My
robot's wheels are wood circles and I just realized that I'm going to
have to make a drive train (since I don't have any powerful motors),
so I need to make some hubs/sprockets (or whatever you call the things
that the chain or rubber band go around to connect the motor to the
wheel). To do that I need a wood lathe.
How do people make horizontal grooves on hubs/sprockets (or whatever
they're called)? I now I can use a lathe to dig a trench into the
outside of the circle, but how do I make evenly spaced horizontal
grooves? I'm tempted to just cover the inside of the hub with some
sand paper. That should increase the friction between the hub and the
I was going to use the drill press to make some large wheels, but I
decided to just live with 6" wheels (the largest size of the hole
cutters I have found).
