Dan,
The weights are 125 LBS each. I made
mine similar to the plans. If you can't find 2 inch channel, use
1/4 X 2" flat steel bar. All it does is give the weight some back
bone and it's a steel component to hold the release
mechanism.
For my mold, I bent a piece of 1/4 plate
into a rain gutter sort of thing, then capped off the ends. You
could make it out of flat pieces. It has to be almost water tight
because the liquid lead will seep through almost any seam water
will. Potters clay can be used to coat your mold to help release
and to dress up any corners in the mold. It's great to make nice
interior radii.
It helps to have the mold warm when your
poring the lead. The lead will flow better form end to end
and it ensures your mold is dry if you use any potters clay in
it.
Remember, you will need something to hold
the steel parts in place when you pore the lead. The steel will
try to float in the molten lead.

weight drop for K-350
Hello, I am assembling the emergency drop weight
system for my K-350, I have a doubt, on the plans they tell me to use a
2” channel (witch I can’t
find locally) and then make some others arrangements, I was thinking
that maybe some of the owners of the k-350 in this forum
could help me by telling me the weight of their bars so I can make bars
of the same weight and dimensions, if someone can help me please let me
know. Thank
You.
