I do use Locktite as well as the washer, though the last time I assembled one of these I couldn't find the Locktite so I ended up using some CA glue. Seemed to work fine. I am curious as to what people do when the original hole is too large. You have to plug it, of course, and I suppose I would just cut a bunch of plugs out of pinblock material and stack them into the hole. But after drilling the new hole for the socket screw, it would seem to make sense to tap the hole prior to trying to screw in the new socket screw. The proximity to the rim presents a challenge for both in terms of speed. The last time I installed these, without having to plug, I ended up taking a hacksaw to an allen wrench of appropriate dimension and chucking it into a brace which speeded up the process a bit (better than turning 12 or so screws in with a small allen wrench. Other suggestions on how to deal with this would be appreciated.

I would be very interested to see > what you came up with. > > Vladan Looking for a better way to suspend plates, that could be adjusted from on top without pulling the plate again, I conjured up a system. I used all thread, cut a slot in the top, and a lock washer under the plate, with an acorn nut on top. It worked great. I mentioned my shiny new invention to Del, and he recommended socket head set screws like he was using, instead of slotting all thread. So much for shiny new inventions... So now I'm using a 3/16" NC (16tpi) socket head set screw 4" long. A nylon insert lock washer goes on it to support the plate underneath, and it is driven into the rim at the old plate bolt locations (or the relocated ones, as the case may be). The plate is lowered onto the bolts, sitting on the lock nuts. Height is adjusted via the hex sockets in the top ends of the screws, and an acorn nut screws on to hold everything when you're done. Plate height can be adjusted later even under full string tension if necessary. The only problem I've had is an occasional lock nut that doesn't want to stay put as firmly as I'd like. A washer between lock nut and plate as David Love suggested to me might take care of that annoyance. Ron N
