Default ASK-21 and Grob 103 cockpit ballast weights

This is not a direct answer but still possibly useful to you.

The ASK-21 weights are lead slabs about 12mm thick each representing
2.76 Lbs of pilot weight. *This increment is too small and would be
more convenient if larger *- say, 10 - 15 Lbs. *The bolt which holds
the weights in place is very long with fine threads requiring many
turns to tighten it. *Flying with CAP cadets and seniors means weights
are frequently changed which has turned out to be a hassle.

I'm considering casting new, larger 15 Lb pilot-equivalent weights
with a captive bolt of the proper length and a large knob for easy
tightening. *These could be swapped out with minimal fuss between
flights. *A pair of these new weights would be about right for
teenagers. *Grob weights can be made the same way.

If you don't have the tools, you can rent a plumbers lead pot and make
simple molds from plaster of Paris.

Bill, thanks for the input. I'm familiar with the ASK weights and
what a PITA they can be - having done numerous commercial rides with
them. If I can't find any, I'll probably get back to you!

The problem is that right now we are using shot bags - scary!.
Fortunately no acro yet, but I'm trying to get that started and we
will definitely need secure weights then.

Cheers
