As I'm in the process of bringing home my J&S540 grinder (no, I haven't got it home yet -nearly there!) I had to upgrade my lifting tackle. My existing block & tackle was only rated at 1/2t while the grinder weighs 3/4t. I was half tempted to give it a try, but thought I'd do the right thing and get some bigger lifting gear. I bought a
1t block & tackle from ebay -looks like the kind of thing machine mart sell from the picture (cheap & cheerful, but it won't get used much). I was rather surprised to find that the chain on the 1t unit was smaller than my old 1/2t unit -and the quality of welding on the chain links was very poor.Has chain got much stronger, or is there something badly wrong here. Perhaps the FOS has been dropped signifficantly -the leaflet with the new block & tackle suggested it had been tested to 1.5t. For the record the chain links on the old unit was 6.4 dia while the new unit was 5.4 dia -but of course this is little help as I don't know the grade of steel used.

Kevin
