Don Mannino's pinning technique using broaches is also described in his illustrated article in the 10-88 PT Journal, pg. 16. This article and dozens of others are contained in the PTG Journal reprint book, "Dampers, Trapwork & Action Centers"; $15.00 from PTG Home Office. At the time Don wrote this there was no supplier for the broaches, but Schaff now carries them, stock #220, for around $14.00. They're an excellent tool. Bill Spurlock
