Aluminum conduit? cut it too long, thread the ends with pipe threads, put a cap on one end, fill it with sand, cap other end, bend it to suit.. cut threaded ends off. thinner tube you will have to turn a plug and dowel it in place. |

Thanks Dawai, I was thinking about trying that trick with sand. I have never seen aluminum conduit but I haven't really looked before either. Aluminum extrusion is pretty expensive where I am but I guess if I don't try I won't know. Thanks for the suggestion Shawn |

I couldn't find aluminum conduit so I am trying a simpler design with plain old EMT. I have removed the galvanized on my belt sander and will have a go at welding it. Shawn |

Hi. well.. looks like you bent the emt allright. I built a buddy a "bush bow" from pvc, inserted plain old fiberglass "electric" fence posts into it. (solid 3/8" fiberglass rod) One rod is about 35lbs, three makes me quiver to draw the bow (somewhere around 100).. SO.. if you do decide to play some more with the pvc?? it can be stiffened up. You can also split a piece of 1/2" and slide it into a piece of 3/4" grey pvc. (use ky jelly) Search on youtube, bush bow, pvc bow. |

Little more progress made today. As soon as I get the neodymium magnets in the mail I'll start working on the electronics. Pitch and roll position will both be read with Hall effect sensors. I wish I could powder coat the shafts but my toaster oven ain't near big enough. |
