I have a 50 % success rate with 4 done now. The more glass, the longer
the pin. Both XS aircraft built prototypically worked with the old
pins. The Classic and a custom built moded tail plane (had a PVC
threaded cover) needed longer pins. I cheat, as I have extra Classic
and XS pitch tubes to allow me to glass the whole thing up on the bench.
Carr Lane supplies 2 inch long pins that work great. About $16 each.

Subject: Europa-List: Europa Mandatory Mod 73 - re -use of original
Pip-Pins through the TP4 and TP6's
<jrgowing@bigpond.net.au<mailto:jrgowing@bigpond.net.au>>
Fellow builders
My study of Mod 73 tells me that we are to put a 10mm piece of masking
tape
on the underneath face of the TP6's to cover the hole and then two
layers of
bid (1" squares) perhaps added to some dregs of dry flox used to fill
the
corners of the hole in the skin, and then another two layers of bid
---From the
8" squares of bid that keep the TP 6 in place.
When I put a pip-pin throught the dry TP6 there appeared to be about
1.5mm
of clearance to the protruding balls.
As I am ready to lay glass, My question is please ---------
Has anyone done the Mod 73 Job and been able to still use their
original pip
pins?
In other words - is it worth striving to keep cover over the TP6 as
thin as
possible?
Or is it just impossible to retain use of the original pip pins?
Sincerely
JR (Bob) Gowing UK Kit No 327 in Oz as I try to complete tailplanes
before
filling them.
