[sdiy] How to mount of module

[shine32]

Hi Lists,

I am using the 904A VCF by M.C.E., and three kinds of hand made VCF.
My own VCF is three types ,4 stage cascade using NJM 13600, state  
variable type connected in 2 stages using SSM2164 and transistor type  
ladder type of mini moog type.
I made the demo.

Now, I have some question.
It is a way of attaching each module to a new wooden case, either  
directly attached or mounted on a metal bar for mounting.
When installing directly, I have experienced the trouble that the screw  
hole spreads out with wood screws, and it becomes ineffective.
Is there any other good realistic way?

Regards,
