Home made,

[AdrianH]

These are two snaps of my home made kart.

Still having some issues finding anywhere to ride. Up to now tried 4 farms and got a no from them.

Took it out of the garage today to help clear some space, and decided to take some snaps with the new camera.

If it runs OK, I may get a modern engine for it as the GX200 is 19 kg lighter then the old G65 presently fitted for same BHP.

Note car exhaust to keep noise down!

Cheers

Adrian

note 2nd go at posting so hope it works!

LOOKS AWESOME. You should have some fun once you find someplace to ride.

Great work. And nice pics on your site, too.

Question: these two pics show that the axle is angled in reference to the spindles.. you said that's 8 degrees. Can you take a few shots of the finished frame to spindle connections, and also mention your methods for finding that angle, and also the method for jigging up the the final frame to spindle connections? That's a difficult thing I think people could benefit from.

Can't wait to see some "in action" pics, too!

also, we ride in a large stadium parking lot. They don't seem to mind. I can't imagine that they wouldn't allow it on the beach -- if you can drive a car on it , then what's the difference? maybe they're imagining that you're bringing a dune buggy.

Hi

I suppose it is reasonable easy to get the angles if you have a mill and an adjustable vice to set the number of degrees you want. If not then the task may be difficult.

The plate the axle bolt goes through was set over at an 8 degree angle and drilled through with an end mill near size, then finished off with a drill to size.
The 16 mm bolt then welded into place.

The axle spindle is 1 inch round tube with Delrin lining as a bearing surface.

With the vice still at the same angle I clamped in some 1 inch square tube (part of the frame). Using a 25 mm end mill in the Harrison milling machine, I the cut in to the end of the square tube leaving a profile to accept the round tube. This was welded up when on the rest of the frame.

I guess pictures will help a lot and I will try to do this for the group soon.

Cheers

I have been unable to set up in the workshop what I tried to say in the previous post, spent much of the time with brush and shovel cleaning up and ran out of time.

I have taken a picture looking at the front axle and hope this gives a better understanding.

The unfortunate thing is it shows up my poor welding and the rust forming on the steel.

Cheers

ah, don't fret the welding, you gotta learn somehow! can you describe how you jigged everything up to ensure it was nice and straight and true when you welded the spindles to the frame? thanks!

Managed to set something up tonight and take some pictures so here goes.

no1 shows a plate in the vice which has been set up at 15 degrees so it is more prominent and easy to see.

no2 is just a top view showing how any hole bored through the plate would be at the vice angle.

no3 is with vice at same angle but now holding 1 inch square tube, level with a 1 inch milling cutter.

no4 is the top view showing the positioning

no5 is at end of cut!

What this does is cut the square tube to take the round tube at the 15 degrees angle as set. The burrs are then removed with file, or sanding belt.

no6 shows it with a small piece of 1 inch round tube just sat in the cut groove.

This makes jigging almost non existent, as the angles are all there, a few tack welds hold it all in place whilst the inch square tube is placed on the frame, squared with a measure, held in place with clamps and again tack welded.

Once every this is checked again the the lot is welded up.

When doing both ends of the "steering beam" which was about 27 inches in my case the tube is turned around and rotated so that the cut in is towards the top.

Hope this description helps and is clear.

Cheers

Oh so you used a boring mill not a vertical mill. I see

 

[RobertD]

Ahh, I see, the angle is cut into the frame member... Very nice! I was hoping you had some good pics of jigging -- i think a lot of people have trouble with that part.

Looks awesome and good luck again on finding riding space!

i use all the things i make on a industreal estate espesaly on a sunday ther are 2 halfmile roads near my house with a huge rounabout at the bottom for artics to turnaround on we never get eny bother from enyone. good luck.

I have got a link to a .mov file from when I took it to work today.

Be warned it is presently 9.1 meg for 45 secs worth, will try to shrink when I find the correct programme to use.

The link is: -

http://www.tamarisktechnicals.co.uk/images/kart/kart.avi This is 5.7 meg file lower quality also may be slow download as from home web server!

may have to remove later due to space!
