Hi All

I have a Boxford model B (rear motor) which has two belts - a
conventional one to the countershaft and a link belt from the
countershaft to the headstock. Both are tensioned by an overcentre type
lever. The belt wasn't new when I got the lathe and hasn't been
changed.

If I leave the belts tensioned the link belt stretches and has to be
tightened before I can use the lathe. So far I've removed 4 links.

Is this normal? Is the belt knackered?

I'd welcome any advice.

Russell

Hi, can't advise on the long term but this used to happen when I had a
link belt on my S7 for a while. I just took the pragmatic route and
released the tension when I left the lathe. The link belt on my
Boxford (underdrive) hasn't given the problem in two years or so,
perhaps they settle after a while.

The link belts do stretch and settle in for a while after installation.
Eventually they stop stretching and settling into the pulleys and the pins
reach their final orientations, but it can take a few hours or operation. If
the belt is loose enough to take a link out of, then take the link out.
Eventually it'll settle down.
