Merl Steam Club Hammer Test

 
 
   
Dodge County Antique Power Club Novelty Mfg. blacksmith power hammer operating on hit or miss engine powered lineshaft.

Here you can see the hammer being shown by a friend of mine at the blacksmith shop on the show grounds of the antique tractor club I belong to. This one was made by the Novelty Iron Works around the late 1800's to the early 1900's and was intended to be semi portable for the mining and logging industries. You can see how much faster it runs from the line shaft that runs everything in the shop and is powerd by a 10 hp Russell hit n miss engine. You can also see the pronounced "whipping" effect of the hammer produced by the higher RPMs. Without the ability to adjust and fine tune the eccentric and the hammer position this hammer would hit no harder than mine does ( I think my seven year old son can swing a hammer harder . . .). When I decided to build my own hammer I was going to make an exact copy of this one but, I didn't like and still don't like, the idea of re-bending my own springs. You can see how drastically these are curved and I do worry a little that they will break while in use one day. In my design I use a combination of compression and extension springs to achieve the same effect on the linkage as the bow spring does but my springs are confined to a guide pin and have a safety cable running through in case the end coil should come off. I'm confident that my hammer will work as intended after some revision and fine tuning.
