Good advice, Al - I am all for the belt-and-braces (I think that you call the suspenders!) approach. You are not caught with your pants falling down! Electronic equipment can fail at the worst possible time, but mechanical things just soldier right along. Might be hard to make the electronic equipment work for threading also now that I think about it. Belt and Braces (suspenders) falls into the Charles Brumbelow category. Charles bought a Cli-Shay a few weeks ago and the tie down straps he had attached to it weighed more than the locomotive!! [:>) Jesse the Red Neck Tennessean MODEL ENGINEERING DISCUSSION LIST.
