Hi MF, Norm and Max,

Even better news is that the weights are only a few dollars on eBay
The one I was looking at was cast iron with a steel sleeve and rubber coated
All of which you do not want
$3.00.
Our PT does have a slightly heavier pulley but nothing like 800g

It kicks a bit but not too bad
We are used to pulling pretty hard to start it
It can stay as it is for a while at least until I get to Eden next which won't be anytime soon
Well done Max & Norm in solving a very long standing problem
Jeff
