I have mentioned this before but now that photo's are easy to post will mention again.
Putting nutplates in piper channel either requires extra holes and trouble for 3/32 rivets
or drilling 3/16 for #6 rivnuts. I don't like either option and do it as follows. Drill all the #6
holes drop in #6 non-floating nutplates held in place by #6 3/8" Long SS screws. Then
I fill ther channel with the dental impression tray resin. Look at the three photo's
Advantages are 1. very fast 2. does not weaken channel actually makes a little stronger
3. fills and seals channel to keep out water and dirt. I did my Colt this way and have had
no problems. I am doing the Cub same way which it is the cub in photo's. After the resin
dries in about 30 minutes you can sand flush with channel and unscrew the #6 screws
and the nutplates are forever held in place. If you ever need to replace one a dremel can dig out old and then resin in a new one. The resin bonds very well to inself.
