Greetings once more,
Firstly, thanks to those who responded to my post below regarding tool post diameters. I have now bought/installed the Woodfast MC900 and have even managed to turn out 3 tool handles with a reasonable degree of success.
I can detect some vibration when working at the ends of the 300mm rest, but probably no more than reasonable and generally only when roughing the blank.
While working on the handles I have been checking the lathe to confirm that everything is OK. I noted that the bearings are running quite cool (just a little warm to the hand) but the drive pulley was in fact quite a bit hotter (not too hot to touch, but noticably hotter). The heat is clearly coming from the friction of the drive belt as it rubs against the pulley sides. I am quite sure that the belt is not slipping given the amount of tension and also the light cut that I am using. The belt is a standard type V belt and appears to be in quite good order.
So, the question is: How much tension should be placed on the drive belt and what is the best way to measure it ?
Thanks in advance,
Rebus
