There are several categories of authorizations in the machine shop.
* Cold Metals Tier 1 - the non-precision machines. This includes the Johnson horizontal bandsaw, the DoAll vertical bandsaw, and the Rockwell drill press. Contact Chris Ruhland (ruhlandc at gmail.com). ***NOTE: Prior to April 2017, the hot metals grinder and cutoff saw were included in this authorization. Currently, the hot metals grinder and cutoff saw are covered in a separate authorization, Hot Metals Tier 1***
* Manual Bridgeport milling machine. Cold Metals Tier 1 authorization is a prerequisite. Contact JP DeBauge (impatientinventor at gmail.com) or watch the mailing list for the next session.
