[TheForge] Repairing power hammer dies

[Chuck Robinson]

My old style 25 lb. Little Giant had a wrap-a-round hammer head guide.
When I purchased the hammer, the guide was broken into 3 pieces ,because the 
ram linkage had pounded the bottom sides of the guide. This was caused by 
worn down die blocks.
Was a real pain rebuilding.
Also made new dies.
