			I've been trying to use a good old rheostat to control the speed of my screener motor and it worked for awhile till it got a little warm and now lost any real adjustment. All out or nothing. 
		
		
		
		
		
		
		
		
	
	So , the reason for my post.... I found something others may be interested in. Very, very in exspensive . $7.37 Canadian, free shipping! A speed controller that can handle 5-16V. 200W and a 20 amp max. Tested tonight and it works perfect! Precise control through the entire speed range and maintains strength from free wheel to loaded. I am so impressed and happy, I ordered another to use for testing motors, light circuits etc, at whatever voltage I want! ![]() ![]() ![]() http://www.ebay.com/itm/191285101601...%3AMEBIDX%3AIT Mario  |

			Looks great, sold out and they do not ship to the US. Hope it does what you need.

			Thanks for posting Peter. I forgot to mention I found many suppliers of these units. I forgot about the one with the reverse option. That would be great for testing stuff
