Shanghai Scrambler

Spent the day proving that a long enough lever or big enough hammer will bend any piece of metal into just about any shape. As the pictures show, I'm fabricating an indexed drop down kickstand to balance the weight of the rear-mounted engine. The two legs are kickstands from fold up bikes someone gave me eons ago and the base is a steel rod bent in the shape of a triangle. 3/8" bolts hold the legs in place via pivot points behind the axle on the dropout plates. Detent balls under pressure from fairly strong springs will index between the up and down positions. The third picture shows notches for the detent ball. Will be just short of a miracle if this Rube Goldberg setup works.

Squared everything up on a chopping board before tack welding the base to the legs. A threaded rod held the mounting plates at a true 90 degrees.

Making sure everything is level so it's straight on the bike.

Here's how it holds the rear tire off the ground.

Viewed from the front. Note the vintage brake levers robbed from my Raleigh donor bike. I like the way they feel better than modern levers (they are harder to install with their funky tightening screw and they're not threaded for cable adjusters.)

Found a U-shaped piece of tubing in the parts bin that fit perfectly on the seat spring bolts to serve as a grab bar for pulling the bike up onto the stand.

Last step was to remove the aluminum side kick stand that will now go on the Raleigh/Bike Bug build which will use up more spare parts.
