That'd be my choice. Assuming that's a 3/16" clevis pin through the flange, you need 9/32" from the edge of the hole to the end of the flange. I'm betting you've got a LOT more than that, here. The only hassle is that you'd have to repaint the end of the flange where the material has been ground off. For those who aren't aware of it, the standard "Edge Margin" for placing holes along the edge of a sheet of metal is that the center of the hole must be located at least two times the diameter of the hole from the edge of the metal...or 1 1/2 times the diameter from teh closest edge of the hole to the edge of the metal. > > Then, it occurs to me to drill a couple of small holes, just big enough for > the safety-wire, on either side of the clevis in order to anchor the > safety-wire. I wouldn't drill the turnbuckle. However...you could pull the cotter pin out of the end of the clevis pin and run the safety wire through IT...in other words, use the safety wire to both secure the pin and keep the turnbuckle from rotating. Or even just wrap the end of the safey wire around the shaft of the compression tube itself. Just as long as it'll stop the turnbuckle from spinning.... Ron Wanttaja
