Air hammers for Pin torque

[Barrie Heaton]

Hi Diane,

I use a piano tiller for uprights, too much like hard work blocking it 
up to the height of a grand.

Neighbours have not complained about the banging in the past, boy they 
complain about the drone of the compressor,  when I put  the compressor 
in the garden shed, at the bottom of the garden  which is not as sound 
proof as my workshop, it back under my workbench for now.

Regards

Barrie,
