    Where would you run the studs? Not much snow down here, but if you went riding in some of the higher altitude regions nearby (north AZ gets a lot of snow in places, but not guarantee that the trails will be open) they could be useful.

    Anybody any good with Sketchup? I need to model a small part for my bike, then print on a 3d printer.

    It's about the size and shape of a small sewing thread spool. I have all the dimensions and a freehand sketch of a blueprint.

    I've played with it a little, and a friend just got a large 3d printer that I'm hoping to get some time in with.

    I can probably do it in SolidWorks if you can send me the drawing.

    Thanks for the offer. My drawing is very crude, I would need to clean it up a bit so someone other than me could actually read it. LOL, 40 years since I took drafting.

    Prototype parts, extremely rough. I had unwrapped a a coil when recycling copper and this was a suitable starting point.
    The peg is a golf "T' cut down. This actually does work to fix the broken button in the speedo, which selects or toggles the different readouts of the lcd dash.

    This is a common problem on the Husky TR650. My other bike the button is broke, and I still have the button, on this speedo, previous owner must have tried to fix it and the part was missing. Gluing would only be a temporary fix.

    The plan is to fix my Terra, and post the DXF for others to download an print for their repair.

    Here are my gnawed off parts.

    This is the speedo where the fix is to be applied. Notice that the micro switch is not centered in the part that appears to be round.

    And this next pic is how it all fits together. Some of the TR650 folks are gluing and adding wire support. This fix is a drop in and fix, no drilling, gluing etc. The spool keeps the peg on the microswitch and aligns the button that gets pushed.

    OK. I think I can work with that. I'll try to work on this a bit over the next couple of days when I get a chance at work.

    Here is a more detailed view of the top. There is a mistake on this picture of the drawing. The 13/64 radius is supposed to be in 32nds. I didn't break out the trig to figure the points in the arc etc, let them fall where they may, so to speak.

    I see this part in 3 pieces, a top flat plate a center column and a bottom plate. The bottom is keyhole shape, the top is more like a cam lobe shape. The plates really can be any thickness, the column is not centered in the arcs of the plates, as by the double center points. The peg, or pusher, needs to be attached to the spool, for 3d printing, and the broken loose and debuggered for installation.

    It really is a project I should use to learn sketchup. I have a student version of solid works that has expired. They want $20 and all my paperwork again for another year of license. If the drawing is in solid works and I don't have it, I cannot make the small changes. But the part is small and a file will fix most issues.

    The one issue I haven't worked out with this is where the radius meets the straight line, if it even does. The flat portion would bump against the speedo housing, the top curve fits into the speedo skeleton. The round or transition area where the line meets the arc in the photo drawing is what isn't really dimensioned, but by the pics needs to kindof look like that. The half inch is somewhat fussy based on a 90º from the line to the widest on the ark in the top.

    Yesterday I was working on a bug screen for my Scrambler. Got the basic shape ironed out. Need to make up some mounts and clean the screen. This is made from an old Mac Studio Display case.

    I love it when my hoarding pays off and finally use that widget I was saving.

    That last drawing presents some confusion. I think unless there is a more detailed and clear drawing I am going to have to pass on modeling this. If everything was easily understandable this would be pretty quick to make. I'd also suggest presenting your information in decimals instead of fractions. Maybe you can try making a 2D drawing in Draftsight. It's a free program.

    Yeah, I get it. I would need to clean it up.

    Interesting.
    They say that any lock can be cut in under a minute.
    I can hold my breath for a minute.

    Right...I actually think it would be more effective with no markings.

    But depending on what they are using, holding your breath may not work. Pepper spray, for ex, is based on contact.

    Clever idea tho.

    Agreed. Or disappearing ink. Or not disappearing ink!

    Fox piss, or skunk scent would be a nasty surprise if they weren't expecting it.
    I use a disc brake lock on the Beastie. I don't see anyone cutting it, and trying pick-up a 400+# bike and loading it into a truck would be a neat trick. When I'm out I always park/sit where I can see it.

    The main problem with a booby trapped lock is no boobies and possible criminal charges.

    People have gone to jail for booby trapping their homes when a perp gets hurt committing the crime.

    Sounds like two main problems.

    If someone wants what you have bad enough, their going get it. There's some pretty smart thugs out there....that said, there's some stupid ones too. Here's a recent example. Dude steals a 950 SuperEnduro middle of night at a Tennessee campground while the owner is sleeping in his tent. Thief breaks steering stem lock and hot wires it. Rides it a couple months and then posts it on Craigslist in Tennessee. SE's are going for about $7k to $10k on average. This ad stated, "950 SE for sale, no decals, no title, no registration, no keys, $2,500". True story. Owner got word of the ad, Sheriff set up a sting, owner got bike back. Idiot got arrested. True story.
