Speed Control..

Good . Southland Electric puts out quality products . Let us know how you like using it . You shouldn't lose any torque with that set up . I've noticed (as mentioned previously) that my variable speed Delta bench grinder when operated at the at the low end rpm's does not have as much torque as it does at the high rpm's . I can stop the wheels while grinding 1/8" ATS-34 . So, I have to run it at higher settings when lopping off metal . DM

Just bought a speed controller from ebay:

http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=200539291167&ssPageName=ADME:X:RTQ:GB:1123

They make smaller ones, that should be overkill. Suits 110 and 240V

It's to suit my 6" bench grinder for paper wheels. Will update when it gets here and if it works.

I got the speed control delivered and played with it tonight.

Works great!

I made up an extension cord with the box and the knob for the adjustment in line, now I can try it with anything.

It works perfect with my $54 6" bench grinder (from Repco), my big bench grinder, belt sander and angle grinder, everything I've tried it with.

It does reduce the torque when turning at very slow speeds of course but that's fine, if I need more torque I dial up a higher speed.

I will mainly use it with the paper wheels on my 6" grinder, slowing them right down for very careful final passes. Used the wheels on a medium/slow speed for about 10 minutes and the speed controler barely got warm, no need for a heatsink on it with this little grinder.

For 30 pounds delivered from the UK it's a bargain, highly recommended :)
 
So what’s worse case scenario if you use this on a brushless buffer? Seems to work from the post above.
 
What part of "it will burn up a brushless motor" don't you understand?
Variable speed is easy with DC motors and a voltage control.
