FS: ECCENTRIC ASSEMBLY TOOLs

My Mosquito, back in the 80s, came with an assembly lever like the Libelle.
I have a friend with a Mini Nimbus (same wing) and it has no such
capability. When he got the glider, part of the kit was a tire iron with
the sharp end dipped in the tool handle rubber stuff to soften it a bit.
The theory was to put that through the main pin bushings to pull the wings
together. I wonder why Shempp-Hirth copied the wings and not the assembly
method.

Chip, My first 2 gliders both had levers for assembly (Jantar and

Libelle) and I can't understand why more manufacturers don't use this

method. The tools I make are made from Delrin to be nice to the spar

bushings. The tool also protects the bushings from the wear of using

the wing pins to bring the bushings into alinement. One would work

quite well on your -24.



I have used a steel eccentric tool (I like the Delrin idea better),

which did a nice job of pulling the wings together; however, my

experience on both an ASW 20 C (1500 hours, about 400 riggings) and an

ASH 26 E (3400 hours, about 700 riggings), is the wing pins don't wear

out the bushings. No discernible wear, in fact.

Don't underestimate the importance of a good, preferably synthetic grease
when assembling any glider. A couple of years ago my tie-down neighbor
showed up with his brand-new ASG-29. We just about killed ourselves a couple
of times trying to get the heavy inner wings on until I gave him my Super
Lube synthetic grease (what a name!). He did have the undersized main pin
from Schleicher to align the wings but that still didn't help much.
Super Lube to the rescue, don't go to the glider club without it!

They have "Templins" at the Schempp Hirth Factory, so no problem!
