Subject: questions about Hightechsystems1's homemade PCB router

From: Ted Huntington <thunting@...>
Date: 2003-12-05

The homemade PCB router Hightechsystems1 made is impressive. I have 3
questions:

1) Are those motors DC gear motors or stepper motors? They look like DC
Gear motors.

2) Did you have to make any gears for this device?

3) As far as I can see, each axis uses a long worm gear in between two
cylinder beams that keep the drill, etc...moving in a linear direction
(as opposed to rotating with the motor shaft). But I see what looks
like a very low thread on the worm gear cylinder in the center...that
makes me think that there is a different variety of worm gear
techniques/structures. Can somebody describe the gear structure for the
long worm cylinder-movable part?

I was glad to see https://sdp-si.com/ now has an online catalog with
prices for gears, that is awesome.

thanks
Ted
