REFLECTOR: Threaded hole strength

[Jack Sheehan]

Darrell,
I don't know what really big hatch (RBH) you are building there are a 
few versions. Here is the one I have. This was my prefered opening 
but as i was building I started to get concerned about the opening in 
flight and I like you did not want any external screws etc. I dont 
have any good photo's but what I did was make the hatch open from the 
rear . like a british auto bonnet . That way it would be held down in 
flight. The cover pivots on an axle which is glasssed under each side 
of the opening the axle can slide enough so the cover can be either 
just opened like a hood or totally removed. Hard to explain but if 
you are using the same RBH you may be interested.
Oh by the way this is really neat but way too much work to remove a 
few screws. Having done all of this I think the removable dog house 
with piano hinges inside is probably the best set up I have seen. The 
reality is I don't need to get in behind the instrument panel or on 
top of the canard very often.
