Engine Box

 

Collect these parts:

 

ÿ

  6 plywood sides of Engine Box

 

ÿ

  2 sizes of Wooden Triangular Stock 

The 6 pieces of the Engine Box are all notched differently to assure correct assembly.  Trial fit all the pieces. 
Sand if necessary.  When satisfied, glue all pieces using 30 minute Epoxy Glue.  Hold pieces together for a tight 
fit using clamps.

 

Note: 30 minute Epoxy Glue is often better than 5 minute Epoxy Glue because it has more working time and is not as brittle.

 

Remove clamps when glue is set and sand a slight bevel on sides and corners to help with clearance when sliding into place.
