i have owned an RF45 for 3 odd years now and my ears can't take them ruddy gears any more. so for the sake of my hearing i think it's time for a belt mod. but what sort? i have seen many types of belts being used..... apart from one.... the common V belt. there is probably a reason for this, but i cant figure it out what that may be. it might have something to do with efficiency. but saying that, Bridge Ports and such other milling machines have been using V belts for years and they seem to do all right. at the mo i can think of three belt options. 1 V belt 2 toothed belt (5mm pitch) 3 poly V belt. i would like to go with the poly belt, but at the mo i can't find a place on the net (UK) that sells them in X length. toothed belt would be the next one and the V belt would be the easiest as the pulleys are not that hard to make. any ideas/ thoughts?
