hey guys im building my own Fett can and i have a question. im going to cast all my parts after im done so that i have a nice strong but light helmet.i plan on doing this for the rangefinder stalk as well. but i plan on putting some thin metal tubing in the rangefinder (to run wires for the electronics and to make it strong) i was planning on using aluminum tubing or even thin wall brass but im wondering if all that and the plexiglass on the end will be too much weight for the servo on the inside. obviously another alternative is to use plastic tubing but that sacrifices a little strength. above all my main objective is to have something that i can put IN the mold before casting to maintain the hollow portion for the wires and make sure the thing wont snap when going up and down due to the weight. metal however would alow me to braise it to an axel making the connection to the servo a bit easier and more reliable. or a set screw into a recess in the axel.
anyway thoughts on this idea??? also if anyone knows any Online stores preferably in the US to purchase such tubing about .125"x.125" without having to order a truck load. but still enough for a small production run.
