RE: Modelbau MB339 buildout
Ok...the work continues...
The rear bulkhead was fitted first and the remaining parts of the mount were located off of the rear bulkhead. Picture #1 shows the rear bulkhead in place.
I used my laser system to zero out the air frame and get the bulkhead in at 90 degrees. Picture #2 shows me getting the fuse lined up at zero degrees incidence.
Picture #3 shows the front bulkhead before it is installed. Making these bulkheads is a sand and fit kinda deal. What I do is I make a cardboard or poster board pattern by trimming and fitting and trimming and fitting.....after about an hour I have a pattern I can transfer to the plywood. Then I cut the plywood out staying slightly outside the lines of the pattern so I can sand it for a perfect fit. It takes time to get it right but once its done and glued in it will not move or fail. Because it takes time is exactly why it is not done from the factory on these cheaper models.
