The following description was provided: ================================================================= Hello. Here are three pictures of a tramming arm I built for my Bridgeport mill. I used two pieces of CRS and one round rod of O-1 oil hardening precision ground stock, 7/16" in diameter. I cut the taper on my bandsaw, cleaned up on a horizontal mill, drilled the lightening holes (which are really just for show!) and TIG welded the parts together. They work well with my dial indicator which has a lug back. Matt Isserstedt 07 Dec 2002 matt.isserstedt@gm.com tramming_arm_1.jpg tramming_arm_2.jpg tramming_arm_3.jpg
