Based on the past discussions, I have decided to use CA hinges rather than the plastic hinges with epoxy install on a couple of H9 ARFs.
My question is: What is the best way to get past the large pre-cut slots that have already been cut in the factory? My thoughts are that the CA hinges placed in the same [large] slots will be very loose fitting and will not bond correctly.

I would cut new slots, except that it will be impossible to fit a new slot close the the ends of the control services. [As their are already the large slots located in these important locations.]

Let me know what you think.
