Wildcat's right, except pedaling backward was low gear, forward was high. You can see how the top chain line goes to the smaller of the two rear gears. It's essentially two freewheel assemblies mounted to a single hub shell.
I've been using these for years. I buy 'em from the Dollar store, though they are a little smaller than the traditional 13x9 inch. I like DGM's muffin pan idea, too!
Stumbled an this neat little DIY tool for rust removal in the nooks and crannies. I've encountered end-brush setups before, but they were never this small and versatile. Now, there's finally a use for all those keyless cable locks I find cut off at the co-op!
With measurements, those items wouldn't be hard to replicate, but I've been searching for years to find a way to capture more complicated images on curved surfaces. A Japanese company was working on a flexible scanner about 20 years ago, but the project apparently stalled. Bummer.
Yeah, I always support the fork at the crown, rather than on the blades, to ensure there's no risk of damage. Usually, it's just straddling a length of 2x4, but inverted works too.
Can someone please slap me and tell me that this isn't a vintage Troxel springer polo on a local bike for $25 bucks? Pics aren't the greatest, but the saddle appears to be white vinyl w/ silver piping and a small round reflector affixed at the rear. To my eye, it's the proper 'surfboard' shape...
I have a squeeze bottle filled with alcohol that I can squirt under the grip, then gently twist it until the bond is broken. It eventually works its way along the full length, the grip slides off easily, and the alcohol evaporates.
This is gonna be an interesting build! My local co-op keeps one of these rim straighteners around, but I'm first to admit it isn't the easiest tool to use.
That mag makes me miss my Screamer 2 even more.
Wildcat scoops me again! I like it--just needs a seatpost & saddle. If the wheels are wobbly, service the hub bearings first, then re-assess. You may not need to touch the spokes, other than to polish them.
