Europa-List: Mod 73 results

[nigel charles <nwcmc@tiscali.co.uk>]

Having done Mod 73 I have the following comments to offer:

1.      As peel ply can suck resin from the cloth I find it is important
to make sure it is well wetted out when laying it in position. Otherwise
a partially dry lay is discovered after peeling off after cure.
2.      As a result of the above I found that resin had puddle slightly
in the bottom of the lay up. This has added a small amount to the final
thickness which has ensured that I need longer pip pins.
3.      By chance I have a length of aluminium tube which is a perfect
sliding fit to avoid having to do the lay up on the aircraft. Even a
patch of the thinnest packing tape almost gets scraped from the tube as
it is inserted. With a little grease it did finally make it through to
the lay up area. This tube was long enough to do both tailplanes
together and is available for loan.
