Hi Brian,
Darn! That really stinks. However, I have had much worse experience with APSCO hammers. In fact, I keep a picture that clearly shows how they incorrectly bored the angle of the hole on a set for a beautiful Knabe Ampico. I was livid and after trying six hammers and taking the pictures, I sent the pictures and the hammers back. That's when I started using Schaff. BTW, I never paid the bill for the hammers at APSCO and about a year later I got a letter from Ed asking what the problem was. Seems Chad (Scad?) never bothered to tell him about the problem. He apologized but I haven't had a set made by APSCO in over seven years.
If I were really dissatisfied and I could afford to wait, I'd send them right back and tell them to try it again. I've done that once. They apologized profusely and the 'new' set was virtually perfect. One thing that I also do is write a letter explaining all the parameters I want them to use. I measure the bore angles and depth and supply them with those measurements. I also send lots of sample hammers, usually ten or so and I leave a few of them 'connected' to the shank.
Regarding fuzz and hardness, I always shape and voice a new set of hammers. The cutting process leaves the crown concave due to pressure differences from the inside to the outside edges of the hammer. Voicing new hammers is imperative.
I'm going to copy this to the Digest. I think we may find another hammer maker that does a better job every time.
Musically, John
