Happy building!

Looks like I'm in!! thanks guys;
To start assembly I made a fab table out of plywood painted white for layout lines and hold parts in place. The rear carrier plate was than centered and screwed down to stay. I'm using 1 1/4" pillow block bearings for good thrust and radial loads. Next I'm working on the front steering.

Wish I had a little red and blue man to help.

Not me. You know how hard it is to get webs out of a carb body?

Working on the front steering, It's a good time to get your measurements tire width and axle spacing ( wheel base ) will be 54" inch. Building my own spindles a little heavier I built a jig to hold parts and angles in place during welding.

Tie rods are easy and fun to make, 3/8 round stock, left and right die nuts, use tap-magic for all your drilling and cutting. practice makes perfect, for the best hand cut threads use a die nut holder with guides.

Frame work;
With the wheel base and measurements complete, I started the frame work, when cutting, coping, bending pipe I mark TDC both ends mark 4 quadrants so I can cut the same.

Cool i hope to do this stuff one day and just build karts all the time

When your building like this, you get a lot of wild Idea's in you head about the next build?? With this winter weather holding out, things are going fast on this build.

good luck builder's ******************** Armand

Good luck!!!

Almost looks like a possible "Chucky" franchise replacement, if your house is on an ancient indian graveyard

Frame work;
Things are moving right along here as you can see, the frame being the main thing, makes the build fast. Wire welding next.

Wire welding frame & attachments;
This is the fun part knowing Mechanically this is my build and things are going together. The welder I bought at a garage sale last year, The cart my wife bought me for my birthday and I just put it all together this year, very proud to have it!!

This contest requires lot's of photo's So I try, let's see frame, floor pan clips, peddle mounts, steering, The Super Heroes that you are seeing is provided by the Grand Son with fittest.

Hello DIY kart builders;
Working on gas and brake peddles, steering support, I bought the peddles and made them lighter, with a cut out for the throttle clevis 1/4 20 thread. Made two 90 degree bends on my JD one inch dom tubing 0.095 wall thickness. I'm getting some great Idea's for my next kart.

Hello DIY kart people;
Finishing up most of the top stuff, steering, gas & brake peddles, mechanical throttle body, hydraulic brakes. Getting ready to pull the frame out of the jig and Weld the flip side. I know what your thinking?? where are the slick's and motor?? coming soon.

 

[slicksonly]

Hello DIY People;
Hydraulic brake rotor install, the kart is design for two motors so I did a motor set up to locate the brake rotor. I wanted to put a seven inch rotor on the right side, but no room, good place for a right side drive motor but that is not available. So I ended up with a 6 inch rotor under the right side motor. built the bracket holding the caliper using a card board cut out, on to 3/16 steal plate, mark, fab, fit, clamp, hold, and weld. piece of cake.

Ooohooohoo...
I like the twin engines! Dual stage 4s would be absolutely insane! 40+ HP! But then again, that would cost about 1.5k.

 

[slicksonly]

Thanks people for your mechanical observation;
OK with the two motors measured and recorded. I decided to go with one motor with torque convertor drive, I wanted to see what all the fuss was about with the TC. Specifcations 212 pred., tav 30 3/4 12t China brand torque convertor to a 60t drive, 35# chain, to a 12 x 9.00 - 6" rear slick. Speed will be just fast enough for sight seeing.

torque convertor notes:
mounting plate or carrier, make sur it fits flat with clearance for back oil plug fill, cut out for 0.020 th. feller gauge clearance.

the two flat faced pulleys on the inside are fixed they don't move in or out, they only turn. Check for angle & off set alignment, correct any thin g out over 0.063 th.

Safety guard needs to be cut out for chain drive, use dry lube on chain to keep oil and dirt off converter.

Chains seem to like oil and not dry lube so much.

Hi @slicksonly,

Did you have to make the 9/16 spacer for the engine shaft to get the TAV drive clutch to line up ?
