Does anyone have any tricks to make this arrangement more stable?


Have had his problem in the past. The seat would get so lose that I was
afraid I would end up in the bowl ;-)

The problem appeared to stem from the fact that I could never get the nylon
nut tight enough to stop the seat from slowly working it's way lose.

The seat I had a M6 metal screw stud which affixed to the hinge, went trough
the holes either side then through a nylon/rubber washer and finally a nylon
nut. I popped to the local shed and got my self a M6 metal wing nut, a M6
large metal washer, and a M6 star washer.

Reassembled tightened up as far as I dared and the seat never moved again.

Hope this helps..
