If it does bottom, you can start shortening the bolt a couple threads at a time (a bench grinder works nicely) until the bolt holds the granny in place properly.
I've been through this- saved a old crank and got a few more years use out of it.
This is excellent advice, if only i can find the right bolt... This crank, as you may know, is of the type with the spacing washer between the granny and the spider. The bolts are fairly long as it is. i think i can figure out if there are any threads near the bottom by simply revoving the crank and the granny, and using one of the existing bolts to see if it can grab any threads. I believe i'll do that now.
