Default RE: changing footstrap positions

Hi Ian, Steve, and WSGuy,
The Permatex-Locktite Thread Repair Compound is NOT a "thread locker" (although LockTite is famous for their many different grades of "thread lockers").
It's a completely different product that results in high pull out strength
basically new threads after it sets up completely.
Another "option" for Tectonics (and other high end fins with the fin screw threads tapped directly into the G-10 or the casting plastic the fin head is formed from is to use a Keen-Sert SS thread insert.
Just tap the hole to the next oversize (.25-20 UNC gets tapped to .312- 18 UNC) and install the threaded stainless steel insert.
Then drive the locking keys in and you have a very high strength fastening method.
Biggest problem with Tectonics, is that Dennis puts the holes with the threads in them precisely where Larry Tuttle's drawings specify they should be, but if you don't "slot" the fin screw holes in your board, you often end up with a little misalignment. This causes alot of problems and prematurely wears the threads in the G-10 and fin head plastic.
Wish all the board mfg.'s would use Larry's drawings and tolerances (especially for hole locations). Then everything would fit pretty much interchangeably.
Hope this helps,
