i broke mine a couple of years ago and fixed it by drilling and tapping two holes to suit 6-32 x 11/4" bolts as shown in the attached photo... one of the holes had to be enlarged to suit 6mm x20 because the thread is in a very flimsy area and had stripped
BTW the battery cover doesnt have to be removed from the camera as is shown in the photo! the photo was taken after i disassembled the camera for another repair
it works well with a couple of provisos...
1- the bolt heads may get in the way of mounting the camera on some tripods without modification
2-not as quick to change the batteries
3- dont screw the bolts down too tight - or the threads will strip
before this method i made a metal plate, the same shape as the base of the camera and used the camera tripod socket to attach it... thus keeping the battery door closed [ the advantage of this was that i could drill and tap a thread to attach the lot to a tripod - and the tripod mounting hole could be ia the centreline of the lens - making panoramas easier]
