[TheForge] Kinyon style hammer help

[Todd Rich]

Several years ago, I built a power hammer based off of the Kinyon plans. 
I did the modification with the regulator to balance strike and return 
pressures.

Anyway, it seems to have a bit of a problem.  After running for about 15 
minutes, the speed of the ram slows way down.  This doesn't seem to have 
anything to do with the switch sticking (I installed a line oiler right 
before the sensor switch), or the height of the work.  It seems to be 
mostly time of use related.  I need some help in figuring out what is 
wrong and fixing it. I'm willing to post pictures or run tests as 
needed.

Here is a link to a video I made shortly after I built it.
