For holding, through grommets, reverb tank to steel chassis, so not the
usual small ones for DSP boards etc. You cannot reinsert, blind, as the
4 splay bits are permanently splayed out.
Find a metal plate with holes the size to push each rivet in, to close
back the 4 splays, then old soldering iron and hotmelt glue the 4
together.
Reinsert through grommets and chassis, then the closer rivet, with more
force than usual to break the hotmelt .




Hmmm, I've read that several times now and am none the wiser.

I have a picture of a reverb tank with rivets through grommets on a
steel chassis, but then it goes all wibbly wobbly.


I would be inclined to use 4 x 3mm or 4mm bolts and locknuts.



I'm assuming they are these

Disadvantage in method is ye get a glob of glue rattling around in the
bottom of the case :-p


Those are the bulk standard ones, these are 3/8 inch longer in the stem.
The chassis is open on the other side so easy to collect them , assuming
they pop off the end of the rivets, otherwise you have to remove the
main pcb to get to the blind side of where the tank is fixed.
