old style sticks that use rubber baseplates, not springs

i'm talking about the ones that use the big rubber doughnut baseplates.

i would like to know how to harden the rubber doughnut to get a tighter or stiffer feel on my stick? or a possible really stiff replacemeent.
Kevin Mullins:
We used to use black silicone rubber on motor mounts to stiffen them up.
Can be found most any hardware or auto supply store.
I've been meaning to try this out on a pair of Battlezone sticks I have that are shot anyways. (I know there are replacements available though)
So it might be worth trying a thin layer at a time in the "flex" area until desired stiffness is reached. Even thought it might be thinnable so that it could be applied with a small brush.
This is all theory of course, so test at your own risk.

thanks for the input.

i dont quite understand what you mean when you say on motor mounts. how would you stiffen it with this?

Kevin Mullins:
Hehe... yeah, I thought I might throw some people off with the motor mount reference. I'm a mechanic by nature and I was talking about how we used to stiffen up the rubber type engine mounts once they started splitting and such.
We use to get the bigger caulking gun size tubes to fill the motor mounts, but for something like the grommets you would probably only need a small tube to test with.

This is more like what we used on the motor mounts:

I know the stuff in the caulking tubes hardens up more like a solid rubber compound.
I'm thinking a thin layer of similar black silicone rubber applied to the old joystick grommets might stiffen them up as well. And another thin layer could be added as needed to make them more stiff. I was going to try it, but just haven't had a chance to pull my joysticks out of the cabinet yet. 
Applying a layer in the thinner "flexible" area of the grommet on each side and let it cure real good before re-assembling them.

It's only a theory of mine, like I said I haven't tried it out yet.
