Okay, I never drill my Fruils, and I never use the wire that is included in the box.
This is all I need to start..cutters and tailor pins from Wal Mart
The tracks are not sided..insert the pin...
The pin pokes through the soft metal on the other side....then clip the pinhead....
You get two blocks assembled...and you're off! I can assemble 84 track links in about twenty minutes....ready for paint...
These pins are perfect interference fits, but if you feel the need for CA, go for it!
Hope this will work for you..
Steve
