Reading thru my centaur catolog I saw a set of plans with above title. Anyone build or use a hammer made from these plans? Any comparisons to the clay spencer design?

I purchased a copy from Pieh Tool and thought it completely worthless. Pieh told me to send it back and I did, they then refused to refund my money. So I would't buy it or anything else from them…ever.

Seems like I had that book like 10 years ago.  it was interesting, but from what I remember, don't have the book anymore, they copied the little giant pretty much in every aspect, including the maple clutch blocks.  The toggle arms and ram was OK, but I really like the tire clutch on the Spencer hammer.

Thanks for the feedback guys. Sounds like i better steer clear of it

I thought they were good plans and well drawn. He did use a number of unidentified salvaged parts like the cone pulley for the clutch and coil spring. I started building one many years ago but found a LG and then a Bradley and the whole project got shelved and parts scattered.
