I just completed these two items after a few months of fooling around with magnets on the weapons. I had done the regular walkers previously, and thought that my magnet system would work on these as well. Boy was I wrong!
Everything had to be scrapped and a new way developed. This time, I even cut up tiny pieces of metal sheeting so that I would not have to worry about polarity. Given that there are 20 weapons, that could be an issue!
Anyway, these are some quick shots off the production line.
