Weights for building
I have a good tip for weighing down your balsa when building. I do alot of reloading for my firearms,and I cast lead into a mold that makes lead ingots that are 3" long by 3/4"high and 1 and 1/4" wide. They weigh about 6-8 oz. each.Perfect because the weight is concentrated in a small area. for the size they are. The mold is made by"Lyman".T-pins are good,but I find that they work great for weighing down light plywood. Just thought I would pass this along. I don't know if anyone here is into reloading,but if so,give this a try.
