That's what I've shaved the last 3 down to.
Haven't had one problem yet.
Figure that the 1/8" lexan will give additional strength.
I didn't make the 1/4" thing up myself however.
I looked at many original control pannels & the majority of real arcade control panels that are made of wood do rout/shave the area where the joysticks sit down to anywhere from 3/8" to 1/4" & they are plenty strong.
The plastic base of the stick will break before the wood does.
Of course if you are using very cheap soft pine wood, this may not be such a good idea.
