Still need to tune it up a bit, tweak here and there, get the treadle stuff worked out, slower motor but Here it is 4 days later.

Whoa! I CANNOT wait to see this thing run! Not much room in my shop....this could be the perfect compact hammer.

Really slick Sam! You combined various "conventional" hammer design concepts in a very "unconventional" manner. I will be watching as you fully develope this.
 
very nice Sam!

What does the ram wiegh? what did you use for the ram guide bearing surface?

I take it you are using a 3600 rpm motor? is that why you need a slower one? Mine runs on a 3600 rpm motor, and it ran way too fast, so I made a smaller drive wheel for the motor, just took a piece of 2x2" hardwood, drilled it out for a press fit on the motor shaft and turned it down in place on the motor, its only about 1.5" diameter and really slowed the hammer down.
 
Hammer and anvil type steel ? HT'd ?
You could put your motor scooter wheels to good use if you want to make a smaller Power hammer .
 
Looks good, Sam, but I figured you'd offset the ram from the guide to give yourself more clearance around the anvil, like the Bull hmmer does.
 
I totally love that you are using a spare tire and rim for the drive. Clearly, using these solves many problems. I'll bet the hammer weight is over 50#. a foot of 3" diameter round plus the weight of the drive assembly.

Charles is right. We need a youtube of this stud of a machine in action.
 
That is a slick looking little hammer. A nice compact design...good work. I'll be curious to know how the bearings in the pillow block hold up, you're brave putting a ball bearing so close to the part that goes "bang"
 
Some great thinking in this. I like the compact design and the weight down low. I take it you are going to make receivers for dies on the post and hammer ad can adjust the stroke with the heavy duty turn buckle.
 
I wouldn't think hot scale would be an issue with the tire since the tire is spinning and the scale wouldn't stick to any one spot long enough to melt the rubber. However, hot scale being flung by the tire could go quite a distance and possibly be a fire hazard on the other side of the yard. Is this an issue?
 
This is a work in progress. After Sam gets the toggle arm dialed in, he will make a treadle that moves the motor to make/break contact with the wheel. He is still getting things worked out. Then he will add things like die plates, etc.
