Cheap part for variable speed HF 8x12?

[Tekno_Cowboy]

Saw this router speed control at HF, was wondering if it might work to slow down my HF 8x12 for threading operations.

Anyone know if this might work?

[FONT=arial, sans-serif]Works with any universal AC/DC brush type motor, 15 amps and under [/FONT]

Look at the outside of the motor ... if there are two removable caps that hold in a pair of carbon brushes, your good to go.

On edit, the HF site shows it has a single phase AC induction motor, which will not work with a router speed control.

Hmmm...That could be a bit tricky, I wonder if Will or Will might know...

I don't remember, since I actually never used the stock motor - I never turned it "ON". My AC motor was replaced with a 180V DC motor and KB 220V AC to DC speed controller. I don't even remember if I even have the old motor - I might have given it to DonShock when he bought my lathe back in December.

I have used one of those speed controllers on my router. It absolutely will slow the router down, but it also kills the power. I tried it a few times and stopped using it.

I don't think the stock motor does have brushes.

I have that very same router speed controller from HF. I bought it years ago & forgot what I used it for. I do remember it worked for what I needed but I never used it again.

I never thought of trying it on the lathe & I don't think I will.

Thanks, I think I'll go with my original plan of either adding an extra pulley, or making a hand crank for threading (mostly for internal threading). My reflexes just aren't good enough at the stock minimum speed.

There's a guy on the LM yahoo group that put a hand crank on the leadscrew (tail stock end) on the LM8x14. You can see pictures of it in the photos section. http://groups.yahoo.com/group/lathemaster/photos/album/1958881935/pic/list

Try emailing the guy, maybe he can probably help you or even offer the service?

Um, I think that's what it's for? :shrug:

I'll have to take a look at it if I can get access.
Thanks
