Well, I didn't see the paperwork, but here's a pic of the health and safety inspector who signed it off for me:
Risk assessment is simple. Keep body bits away from big hammer or loose them!
Well, I prefer the dynamism of bigger scale forge work. Last candle holder I made was in 4" x 4" square mild steel bar, about 2' long. That was on a 1 cwt hammer and it struggled to generate enough wallop.
I acquired a smaller (0.5 cwt) Massey mechanical hammer a few months back for smaller work (see pic). So the big one (3 cwt) is intended for stuff that the 0.5 cwt can't handle, although the blow energy is a lot more than 6x I think.

Here's the tiddler:
Incidentally BAE had a new patrol boat out on sea trials a few weeks back; when they came to test-fire the foredeck popgun a round detonated in the breech, blowing the gun apart...![]()
Not really Big And Expensive's fault; that's a american gun, albeit on a british-made gunmount.
of course it is... they should be making their own rather than buying everyone elses crap
