Heyho!
(Click the link on the bottom for high-res pictures)
I'm building an oscillating edge belt sander right now and I have some major problems getting the belt to track.
Its a 3 roller design, with two fixed, stationary rollers and one roller which is responsible for everything else.
The two stationary rollers are made on the metal lathe, so I know they are perfectly flat, round, parallel and so on.
The Last Roller has a crown of about 2mm on it.
From the first video you can see that without the tracking roller the belt acutally tracks decently well. By applying a bit of tension on one end I can get it to wander quite nicely.
But despite the fact that flatbelts track towards the highest point, aka the highest tension, the belt wanders to the exact opposite. It wanders away from the point with the highest tension. I really don't get it. Its pretty frustrating to me at the moment,
Any Ideas about what is wrong with my setup?...
The belt is 200x2000mm (~8"x79") The big roller is 250mm diameter (10") and the small ones both 8cm (4")
