Many years ago Jerry Allen of "The Wizards Forge" came up with a power hammer plan that turned out to be very popular. With the exception of a few items like motor and bearings it is mostly made from scrap and salvaged materials and results in a efficient, smooth running hammer that would otherwise set you back a good dollar on the retail market.
I have many sets of plans for different power hammers that I have found on the web, but no plan set for "Rusty", Mr. Allen has protected them well. With me I like to build from pictures, incorporate some of my own ideas into the mix, and alter the measurements to the materials available to me. Norm Tucker below seems to have a similar attitude toward his project creations.
Off all the plans and ideas I have come across, a larger version of "Rusty" appeals to me the most.
This version built by Norm Tucker has high appeal for me. There is very little I would change about it. The idler initiated start/stop feature probably gives good control, but would wear the belt and pulleys out prematurely and because the motor is still running when tension is released there is the chance the belt may grab and give you an unexpected stroke (haven't built one yet, so this is just speculation). I will have to see what I can come up with.
I don't pretend everyone is like me (god no,lol) so if your interested and you need the plans to build it, here is were you can get them.

26385. Ph.# 304 745 3886. A short version of the plans go for $15. More detailed plans go for $40. That gets you plans for three versions of "Rusty".
So many years ago I made up a word file from a web site containing a write up on the materials, sources and some construction methods for Rusty. Also in the file are many examples from other builders of their versions of Rusty such as Norm Tucker's above.
