I posted this on Vansairforce yesterday buthavnt found out what I need to  know so I will repost here. Apologies if you have to suffer my problems  twice!

  

 I am working on the structure that supports the roll bar. It is supported  by a piece of 1"*12 angle about 1/3 of which, according to the plans sits  completely hiden by the F-416 canopy rail and about 2/3 of which causes you to  cut the canopy rail and flatten it out... you remember.



My first attempt  resulted in about a 1/4" sticking out at the front as shown in the first picture  at http://gikonfuse.blogspot.com/



In the second  picture I have shimed the F-417 against the F406 bulkhead and now as you can see  the front end of the angle is about flush with the canopy rail.



Should it  work out to the plans or has everyone had this problem.



Thanks in advance  for the help.

It looks about right to me,,The angle is supposed to sit at an angle,, take the roll bar and "dry fit" to the canopy rails.  

Just set it on top of the rails and the angles should match.

 Hi Steve,

 

 Derrick is correct....You need to build to fit.  Be very carefull and check edge distances closely for the mounting bolts.  As I recall, there's not alot of room for error.
