Achievements

• Jumping 18x (ski training)
• Planned work, and worked very effectively.
• Read through all the applications received (for new job available).
• Carefully calculated the maximum I would eBay bid on wheels + broken quad ($159).
• Rang the Mt Gravatt mower shop and asked about single rear mower wheels (none ... and hard to get, gave me Ph number of "Kelvin" (0418 475 267) to try ... apparently he has a large shed full of old gear.
• Succeeded in buying wheels and an old (clapped out ?) Quad. Going to pick it up (with cash) this afternoon at 5.00pm, from 11 McDonald Street Jimboomba (Mark Jones)

• Picked up the wheels.
• <<<>>> Never buy second hand from eBay, without an inspection.
• Bike is crap. But actually, it is better than the wheels.
• Learned -> 50cc Chinese bikes have tiny little axles. Too small to hold an adult.
• Learned -> Exactly how the rear axle on the tiny little bikes works (in truth, could probably only have learned by dismantling one).
• Worked on "new possibilities" (see below)
• Re-entered objectives (see below)
• Searched for bearings for front wheels (26mm OD 10mm ID 8mm width).
• Total $13 for chinese, delivered, via eBay.
• Found a very cheap possible wheel.
• Discovered GoKart bolt pattern (rear) is 58mm PCD.
• Cheap eBay (new) wheel is 85mm PCD ... therefore, steel flange will fit !

New Possibilities:

Question: Can I use the rear axle ? NO ! Doesn't work !

Question: Can I use the front steering ?

Maybe ... but only if I remake the knuckles so that they have stronger stubs ... so they bear weight better.

Question: Can I use the front wheels ?

Maybe ... but only if it is possible to put new bearings in them, so that they can run with the larger axles

See "Electric Cart Objectives"

Planning #1 - the fastest way to get a Cart

Imagining that money was no object

..... Things to buy

..... -> Cart / Buggy (eBay $750)

..... -> Steel ($25)

..... -> Rear 'flash' wheel ($55)

..... -> +++

..... Total = $ 1000+

.....Action steps

• Buy a working cart or Buggy
• Cut down the frame.
• Buy an ATV rear wheel, blank (without studs cut).
• Have stud holes cut to match Cart hub.
• Install Cart hub in shortened axle

Planning #2 - the cheapest way to get a Cart

Imagining that little or no money was available

..... Things to buy

..... -> Bearing for front wheels (eBay $13)

..... -> Bolts ($5)

..... -> Steel ($15)

..... -> Rear bike wheel ($5)

..... -> Rear bike gear ($25)

..... Total = $ 63

.....Action steps

• Get new bearings for front wheels (eBay $13)
• Weld in M17 bolts (or M16 bolts, or 16.5mm precision rod) to fit.
• Cut the frame down (from steering post back)
• Weld in two straight steal beams to the back.
• Put in a 16" bike wheel, with rim brake ... and adapt gear to correct pitch

Planning #3 - spending some money, not too much

Imagining that little or no money was available

..... Things to buy

..... -> Bearing for front wheels (eBay $13)

..... -> Bolts ($5)

..... -> Steel ($25)

..... -> Rear 'flash' wheel ($55)

..... -> Axle bearings ($20)

..... Total = $ 118

.....Better because

..... -> Great rear wheel

..... -> Disk brake (upgrade to hydraulic ?)

..... -> Excellent TOUGH gearing.

..... -> Same or better than the adapted "Buggy" ... with no waste !

.....Action steps

• As for #2 above ... except ...
• Buy a flash rear wheel ($55 eBay ??)
• Cut round plate steel (to be flange)
• Drill centre hole.
• Perfectly drill other holes (for wheel mounting).
• Perfectly weld (test on lathe, for straightness) to 19mm precision rod axle
• Also weld on disk-brake rotor holder
• Also weld on gear
• Weld disk brake rotor-holder onto axle
• Cheap disk brake to back wheel.
