Default tip-up reinforcement kit

Got the skin on the canopy frame... yeah! Now it's time to do the reinformcent kit. How do you make the flanges on all 9 circles? Or are they needed at all? (In one pic I saw the gentlemen didn't make the flanges).

Did you put the reinforcements on when the canopy is off the aircraft - I was thinking that it might twist. Any guidance putting these pieces of metal on are appreciated.


Thanks much in advance!

Yes they need to be installed. You will find if you make the flanges on each hole that the reinforcement becomes unbelievably stiff. It almost makes it very difficult to even cleco them into place. They are fairly easy to install and you will find anything you can do to make the frame assembly stiffer is a good thing. Even after you complete the entire tip-up canopy you will wonder how this thing will survive if the wind ever catches it one time.

Yes, I know the reinforcements should (have) to be installed. Just wanna know if the bends on the holes needs to be accomplished. I tried doing it and didn't get the technique down.

You just cut a slit and go little by little around the circumference?

Yes, I used a block of Delrin about 3/8" wide and you will slit it about 5/16" deep and bend a little at a time and go round and round a few times carefully and you will create a smooth flange

Default pay attention to the size of the rivet holes

It is possible to get the flange going in the wrong direction if you miss that the center part has pre punched holes of two different sizes, which is the clue for how it fits to the frame and skin. Also, hardwood might work instead of delrin and may be easier to find. Even it the flange is an "outie", it will still be OK.

Default tip-up reinforcement kit

Is this an optional kit or is it part of the finish kit?

Thanks

It's not mandatory... but it is included in the finish kits now. It does stiffen it up A LOT!

Default Process for Tip-UP

I didn't see the answer to on or off the a/c, but I drilled the individual reenforcements to the frame while off the fuse. Then drill to the skin (aft edges) while on the fuselage. This should prevent any twist from getting into the assembly. Then again, there's enough weight on this that it's goign to flex anyway.

Just stop by any place that sells kitchen cutting boards, get the white plastic one. I had fun with a $2.00 board cutting it into various tools and spacers.
