Teardrops n Tiny Travel Trailers

I've noticed several folks have used a router to trim out aluminum but in most of those cases they said they used speed control. What do you use for that?

Can a make one from a 110V light dimmer switch?

...a speed controller is used to slow the router down so that it cuts the aluminum instead of burning thru it. If you use a router full speed it tends to get gaulled up from the aluminum melting and sticking to the bit...a problem solved with a speed controller. I am fairly certain that a dimmer switch would cause damage to the motor, possibly a ceiling fan speed control would work however a speed controller can be had thru Harbor Freight for around $15

Thanks, Madjack. I knew what it was for -- just didn't know where to get one. Looks I'm headed for HF tomorrow!

...no problem rgh, I think I paid $15.99 on sale at HF. Some controllers have voltage settings, the HF one I bought just has a color band on it and I "tune" it by ear

Here is a photo of a router speed controller. These come in handy, not only when cutting aluminum, but to assure the maximum safe speed in not exceeded when using larger diameter bits in traditional woodworking applications.

Just an idea for those of you routing aluminum. an upcut or down cut bit helps to minimize galling on it also, It pulls the chips out of the way and allows a clean cutting face on the material. We used them in the sign industry, 1/4" shank and routed 1/4" material all the time with them, They are available in double ended models also. Not from home depot however, gotta go to an official tool supplier. I've used them a lot, they have 4 flutes to them....I haven't bought one in years, I just used all the leftovers from the sign shop.. They aren't available I don't think with a pilot bearing however. you will need to build a jig...Doug Hodder
