Dowels in carbon/balsa end grain firewall?

[Ihncheol Park]

I remember seeing that someone mentioning the use of 1/8" round ply inside
the firewall (backside) mostly using Hyde type mounts.

The new plane's firewall is 1/4 endgrain / carbon  - is it necessary to
install dowels in the firewall where the motor mount bolts go to prevent
crushing? 

 

Thanks  -
