You might have seen one on ebay recently, well now it's sat on my trailer awaiting instalation.

I've not been able to find any info on them apart from one site by a guy in NZ who has 2cwt model.

People will be able to give a better response from a picture do you mean this hammer:

its quite possible it may go by another brand  as well, looks like a fast sheffield type forging hammer.

Just guesstimating from the picture... I would say around 300 bpm would be possible... (Please don't tar and feather the ph deprived for hazarding a guess... lol )

Seems my earlier attempt didn't post properly. I used to live next to the Hattersley and Davidson works which also included  Robert Sorby  and Kangeroo tools. Primarily H & D were engineers, Brassfounders and pump manufacturers. Sorby's and Kangaroo brands being woodworking, edge tools, gardening tools and they also made some of the best ice skates, supplying them to the Olympic ice skaters, including the Russians who at that time were still behind the iron curtain.  

 

The powerhammers that were in use were mainly Patterson, and I wonder why the one you have is identifiable as an H&D, it was common practice for machine tools to be manufactured and sold under different names, which were usually done by attaching a brass plaque with machine id numbers on and other relevant information which can mislead from original manufacturer, they could also have been made under licence. They operated at about 600+BPM

 

Would like to see a video of this when you get it running. There used to be some of the Paterson hammers at the edge tool makers just outside Exeter around Ide, name escapes me at the moment, but they also took on the old Finch Foundry tooling.

400-600 BPM is pretty fast - would make it tough to do quarter flips on stock.

way too fast. It's theoretical because when I used it it wasn't beating at anything like that.

Morris of Dunsford are the people, thanks for that.

 

The 600+BPM machines were primarily used for rapidly drawing blades down and no quarter flips being used. It's over 60 years now since I saw the works so some details a little hazy, I was only a tacker at the time so was somewhat in awe of these beasties.
