RE: Quick Question About CA Hinges
GUYS:
All are excellent ideas except for the CA'ing one side then the other. They must be done at one time. Here is one other thing I do as I lost a plane to CA hinges. As I watched my beloved LT40 go 90 degrees nose down into the ground I could see the elevator flapping in the breeze. Needless to say my biggest piece was the engine. Anyways since then I see where some poeple would insert a small piece of wood thru the hinge from top to bottom. They would do this after the covering was on. I took this one further. Once im ready to install my hinges I make sure everything is where I want it cut the slots for the hinges and install them. I make sure it moves freely and no gaps are present. Then I remove them instead of glueing them. I get my covering and I cut it to fit over the training edge of the wing and iron it on, I do this on the same for the leading of the control surface. I then get the hinges install them and align it so it fits the way I want it, and then CA it as normal. ( all I have done is install covering in the gap on the leading edge and trailing edge). next I drill a small hole about a 1/16" thru the wood that is holding the hinge and thru the hinge from top to bottom of the wing. I then install a small balsa stick into the hole thru the hinge, and sand flush. The sanding takes a little time. When all the hinges have been installed with the stick and glued and sanded I get the iron back out and iron the covering down. I usually iron it up to the edge when the ribs end at the trailing edge so when I go to finish coveing the wing you wont see a seam. The covering I usually take right to the trailing edge this make a nice neat covering job. Also you cant pull the hinges out. I now have extreme trust in my hinge job. The other reason I do this is that I usually can see the hinge as it is in the wood so Im not totall convienced that the glue did its job. This is just an added piece of insurance on my hinges.
If you guys want I could do photo essay on how I do them.
