I have been bugging you guys about building motor mount models so I thought
it only fair if I set an example.

This is 1/4 scale for the KIS Cruiser. The model rubber motor mounts are made 
from hardware store rubber washers with a 1/4 OD and a 3/16 ID. The bolts are #6.
The "firewall" is made from 3/8 plywood and the "rotary" is a solid block of wood.
The "motor plate" is 1/8 inch model airplane plywood and the "tubes" are 3/16 
square balsa. It is best to drill holes in the plywood to make sure there is
a good glue bond with the 3/16 sq. balsa "tubes". I think it is best to use
epoxy glue. Sewing pins help hold things in place while the glue dries if you 
do not have model airplane building experience. I also built a simple 2X4 and plywood
jig to hold the "motor mount cups" in the proper relationship to the "firewall"
so I could cut the "tubes" to fit.

The "radiator" shown is 1/4 scale  20" by 22" by 1.5 inches thick as I did 
not have any 1/2 inch ply.

The front motor mount is not installed yet.

More pictures to come.
