Hi guys,

I have had my CNC turning shop build a couple of sets (300 + pieces) of what 
I call "bobbins" for attaching all the fairings and dorsal fin. I found that 
the prototype TF with the previously recommended book binding nuts was in need

of replacement of several of these due to stripping of the threads or simply 
being used up. The bad news is that there isn't enough material left to re-tap

or insert these things, so I've had to dig the out and put new ones in. The 
new version are 304 stainless with a 6-32 thread, and an o.d. of .625". There 
are two heights needed because the core material is thicker in some of the areas

on both the wing and the fuselage (the horizontal stab. is all the same 
thickness). These little guys are a piece of cake to install. Just hole saw through

one skin, clean out a bit of the core, push them in until flush, squeeze in 
some adhesive with a syringe through a .062" hole in the skin nearby and you're

done. I'll get a couple of pictures today and post them. Anyway, this isn't a 
sales pitch but if anyone wants some let me know, The CNC program is written 
and all I need to do is make a call and the guys will turn them out.

The prototype TF is getting a new engine (LS6) and will be flying soon. We 
should make arrangements if anyone wants to come out and fly it.

TF, about 80% there. Painting the wing next week. Red.

Ed,
     As usual, you are "Right ON" with this one.   I used the alum "Book 
Binder Nuts"
on the dorsal fin, and found that the threads stripped out after three or 
four installations.  I wound up digging them all out and replacing them with ss

T-Nuts available at your friendly hardware store intended for use in furniture

building.  I have used them for all of the faring installations, including the

wingroot farings and parts of the cowling.  So far, none have stripped out.  
Your system sounds much slicker and easier.  I wish I had access to those 
"little guys" a few years ago.
     To those of you who haven't installed farings yet, DON'T use the book 
binder nuts. 
Ed's inserts may save you Hours and hours of aggravation...LRE
