    $309 actually, plus shipping. So I'm a bad guesser of shipping charges and a lousy mathematician...

    Nope, won't do it. Not when I can build one.

    Ladies and Germs, the Stretchatec Skid Plate...

    [​IMG]Since I don't have access to metal-stamping machines and presses, I had to weld it all together from flat sheet. Each facet is a piece of 1/8-inch sheet aluminum, individually fitted and welded front and back. The skidplate itself was welded with .030 3034 aluminum wire in a MIG machine with 100% argon shielding gas.

    The thickness of the welds gave me enough material at the edges and corners to grind and sand until each corner was nicely rounded. Then I sanded it with 80-grit paper on a dual-action air sander.

    The frame is 3/4-inch steel square tubing. Welding was done with the MIG welder using .023 solid steel wire and 75/25 Argon/CO2. The rear mount sandwiches the centerstand mounts between the skidplate frame mounts and the bike frame. Come winter I'll take it apart and have it powder-coated.

    Detail showing the modified Touratec crash bars. I lengthened the crossbar mounting tabs so that I could use two bolts per side, instead of just one. This keeps the crossbar from rotating up and down. Then I welded a skidplate mounting tab onto the Touratec crossbar.

    It has paid for itself already. I hadn't done any trails at all on this bike, knowing from my Alaska ride (on a rental) how much damage loose rocks can cause. The skidplate on the Alaska rental saved the exhaust and cases numerous times, so I knew I would need a skidplate on the Tigger before I did any serious off-roading.

    I met WIDGIN and TigerRider for some trail riding this past weekend, and I lost count of the number of times I heard big rocks ricocheting off my new skid plate. There are a couple good gouges visible in the above photos.

    Nice job! I didn't know that you can use steel wire to weld aluminum? I have a MIG with Argon/Co2 too but I neve welded aluminum...

    Point taken. I edited the post to indicate the different MIG setups for each metal.

    Thanks. :D

    Very nice indeed.

    I am still a little star-struck by those Jesse bags, but that skidplate is fantastic!

    $400 USD to Stretch67@spankyourmonkey.com

    Models for commercial sale will look curiously like Touratec's. :D



    The above comment was a joke. Don't send me money, because I'll just send you a $310 Touratec and pocket the change.
