Quite often i feel the urge to make something abit uncalled for as a mild engineering challenge mainly as i like to see scrap rubbish become something marginally fun, if a fwd kart could ever be considered that.
Anyhow what kicked this off was idley messing about with a steering column and noting its potential as a driveshaft albiet with limited lock capability never the less ideas where mulled and chucked around and a start has been made with various scrapyard bits and pieces
a mock up was made with a transverse leaf spring (mower blade) lower wishbones (bike frame wheel mount) kingpins (bike bottom bracket) dampers (washing machine drum dampers) and a sack barrow frame/wheels
first job was to make the bottom bracket become a kingpin drive hub assembly, crank arm was turned on the lathe to become a boss and a plate welded to it to allow wheel mounting
bottom rose joint is merely a m10 as it only takes loading radially whereas the top joint is an m14 to allow for axial loading from the spring
cheap wheels needed decentering to remove the hub boss to fit the drive flange
complete hub assy except for the steering arms as they need fitted after the wheelbase is finalised
whishbone pivots are just metal tubes with pipe pushed in to form a sort of bush arrangement
the sack barrow frame has needed a good chop about and still needs braced so it doesnt flex ,first thing i noted was it will need a second leaf srping as it bottoms out with 85kg popped on it
one thing i didnt want was 1 wheel drive so trying to make a ratcheting lsd
first up is a axle driven by a sprocket
center axle needs a bearing housing,,cheapest way to bore out a bit of square box on the 4 jaw
ratching mechanism is a bike rear cassette driven via a removal tool adapted to the center axle
the adapting parts are just a sprocket cut down and a washer which will be welded to a steering column uj
[/URL]
mocked up on the center member other rathering mechanism is the same but for it mounting to a cut down bike hub which in turn is welded to the center axle
the idea is that drive comes in via the center sprocket which then drives the center of each cassette and in turn both driveshafts so that when cornering it will drive the inside wheel and the outside faster moving wheel overdrives the cassette which will aid in self centering under power,,and massive torque steering LOLZZ
next will be mounting a sturmey archer to drive the diff and somehow squeezing in a 70's 98cc 2 stroke into the space
