Is it a bad idea to leave a hole that was drilled for a rivet. I did the layout but  managed to pre drill a hole where I am unable to put the rivet because the 7H2-6 bracket will be sitting partially on it. 



If it isn't is it possible to move the 7H2-6 Bracket at all to accommodate?

Hello Mark, and welcome to the list.

  

 This will be the first of many foibles you will encounter in your 701, and  you DO have options.

  

 I cannot comment on moving the 7H2-6 bracket since I am a 601 builder and  have no idea how critical the placement of that part is, BUT...

  

 IF you can move the bracket so your hole has nothing under it, throw a  rivet in the hole and no one will ever know it's a mistake.  If you CANNOT  move the bracket, a little Bondo and paint will cover it up and again, no one  but you will ever know.

  

 Good Luck, and keep building.

I have seen several references to "filler and no one will know" in situations like this on this list recently. In the real world of certified, manufactured aircraft, any open hole is filled with a rivet if at all possible. The reason? the fatigue strength of the part and assembly is enhanced when the hole is filled - with an expanded rivet shank.

Countersink the hole and put a rivet in with a flat head. Re-install the

bracket over the top. Life is good.

Mark,

    

   Do not move the location of the 7H2-6 bracket. It's position is critical to mount the stabilizer. As a side note, I am not sure what revision you are working on, the newer plans use .063 instead of .040 for the 7H2-6 brackets. If you have the .040 this would be a good time to upgrade them.

you can only do that if the hole to be filled is in a piece of stock that will allow at least 1/3rd of the thickness to remain un-countersunk. An open hoel with clean edges is usually less of a risk than that same hole that has been countersunk to a feather edge.

   

  All of this is covered in the AC565-8, AC65-15, and AC43.13-1 and 2.

   

  Be carefull here guys, fatigue is the silent stalker.

That does not apply to dimpling with a squeezer. If  the metal is too thin to countersink, dimple it instead.

This is a good tiume to purchase some .063 material and make your own  brackets. It is relatively simple if you have a small brake.  The new  brackets are $14.95 each plus shipping.  A 2' x 4' sheet of T6 cost about  the same and then you have some left over.  I learne d this from this great  forum! Thanks!

I agree; change them now to .063.  I made my own, and I didn't even need to use a break.  I sandwiched the piece between two short 2x4's, and bent it over with a rubber mallet.  The radius on the 2x4 was perfect, and I only needed to bend it slightly more after taking it out.  Very fast learning curve also; I only made one bad one.
