My hammer


Recommended Posts

That's a good start, but a few suggestions.  The hammer doesn't look like it's dripping oil and the squeak at the end of your video sounds like metal on metal.  Mechanical hammers should have every moving part oiled every time they are used.  That means all pins, slides, bearings, etc. If your hammer isn't oozing oil from every joint then chances are you are doing it damage.  

 

Also, a hammer that size should be running at 250 to 400 blows per min.  The vid looks slow to me.  Practice stomping the treadle with some junk steel between the dies (hot steel of course) to really get a feel for squishing stock.  If you already have it floored and are only getting low speed performance look into changing your pulley ratios.
