What better time than during the dark days of winter to take a look at refurbishing all of one of one's hardest-working pieces of hardware? More or less standard parts nomenclature: Pipe Bolt: 1/2-13 x 3" Cup Point Square Head Set Screw, ~$1.22/each. Pan Screw: 5/16-18 x 5/8" Cup Point Square Head Set Screw, ~$0.14/each. Yoke Bolt: 1/2"-13 x 1" A307A Low Carbon Plain Finish Hex Bolt, ~$0.39/each. Washer: 1/2" Flat Washer Lock Washer: 1/2" Split Lock Washer An alternative to the two items above: Belleville Washer: 1/2" Belleville, .512 X 1 X .039, 1050/1070 Plain Finish, ~$0.76/each. I highly recommend the Belleville washer instead of the flat and lock washers. I first learned of this due to the Mega-Clamp, which does not have a Pan Screw. For those wondering what prompted this...I refused to believe the stagecraft mailing list when it was said that 1/2" I.D. Schedule 40 steel (sidearm) pipe would not fit in an ETC C-Clamp and thus Altmans-only must be used. I had to see for myself, and yes Virginia, it's true. [edit: ship said it here on 11/01/07, but the wheat must have gotten lost in the chaff.] I love sidearms, and am very disgruntled at ETC right now, especially since they've kept this a secret from me for sixteen years. I suggest everyone purchasing new fixtures to try to get his/her dealer to substitute a Mega-Clamp at no extra charge.
