What should the gap be - between the hammers and the side of the spreader?
Thanks

Just whatever it takes to stop the racket and a little bit more to allow for the chain stretching.

don't people usually shorten the chains by putting a bolt in them?

That's the usual way.

Really wants to be the next link to the rotor, or the bolt can do damage to the rotor tube.

So the hammer should be as close as possible to the barrel - but without actually touching it? I wasn't sure if there was a manufacturers recommendation of an inch or something like that - to allow for stretch.

Better with at least an inch gap. The chains will stretch soon enough.

On a new machine, the chains can be 2" from the barrel. This will allow you to do several hundred loads before the "hammer" touches the sides.

However a rotorspread gets more efficient the closer they get to the side , because you can empty more of your load.

On my last Fraser Muckmaster, I cut 2 links off the rotor end of the chain,refitted with a new bolt and turned the flail head around so the square corners would dig in better.

When these started to touch I replaced with new chains and flails.Should have done this sooner because the performance was much better with a heavier head.
