This is a clip of me running a hammer I designed and built as an experiment in "what can I do with what I have around and can get from the farm supply store"
As you can see I have omitted any means of adjustment for the eccentric stroke and the hammer carriage position.
As a result this is as fast as I can make the hammer go before the carriage over travels off the track.
It is not near fast enough to take advantage of the inertia cycle of the reciprocating parts to increase the hitting power as the design is supposed to do.
This hammer is supposed to work by the same principle as the "bow spring" style made by the Novelty Iron Works in the next video
This video clearly shows the importance of the adjustments that are missing from my design.
At the time I was building my hammer I didn't have a piece of round stock big enough to make the eccentric with an adjustment T slot in it and, I was trying to get it done by an unrealistic schedule.
You can see it is only finished enough to make the video.
What you can't see in the shot is me stepping on a foot bar that turns the gear motor drive on and off directly.
The gear motor has an output RPM of 160 and is a 3/4 HP 110VAC input motor.
I need to get the blows per minuet up to around 300 witch I can do by changing pulleys.
