I don't mean to be critical, but you have to much heat in your welds on the last pic. To much heat will make the metal weak and prone to breaking. You are doing a fine job.

Harbor Freight Predator 6.5 HP.
By all means, critique my work, that's what I have pics up here for. I have all of about 30 minutes of welding with wire feed. You reminded me that I took more pictures of my brakes that I wanted to post up.

I like the way that you installed that brake of yours. Very clever. Have you got any idea why it is now working as it should?
Because the pedals being attached to the mesh like they are allows play in the system. In addition, the way I connected the cable to the rod in the front has some play, and the rear lever requires too much travel. So when you combine all three factors, I can't put enough pressure on my calipers once the cart is in motion, and I am in it adding 200 pounds to its load. I have a few idea's to fix it, just haven't drug it out to work on it.

Thanks. My next design will use the same HP but not sure whether they have the same capability because mine is not branded engine. Mine is Chinese made gasoline engine.
As far as I know (I could be wrong), but the Harbour Freight engines are also Chinese knock offs.

Daisan76,
Looking at your kart, may I know a few things about it:
1. Diameter of your rear shaft?
2. Diameter of your rear wheel?
3. Diameter of your front wheel?
4. The speed of this build
Sorry if I did not follow-up closely the discussion and may repeat the questions asked by other members.
You know that I like big wheels and working on the same type of build. The best thing with the big wheel from what I like they are all the cushion and shock absorber.
1) 1 inch. From Northern Tool
2) 15 inch tires on 6 inch rims all corners
4) I spent about 20 hours on it so far.

Thanks Daisan76 for your reply.
I believe we have the same size of rim and tire (if not almost there). I like the look of your steering which I have welded 2 units and plan to use it in my second design.
Have you tested the maximum speed? My first design can reach 30-40 km/hr by using a motorbike engine Honda Hurricane 110 cc.
Second design which I am working now using the gasoline engine 6.5HP with centrifugal clutch. That's why I want to know what maximum speed you could reach with your build to estimate mine as well later. This is first time to use such system.

Oh speed. hehe, I have it geared down pretty far. It goes about 10-12 I would guess. I run mostly in my backyard, so that is as fast as I want it, with no suspension, even small bumps send me flying.
The steering sucks to be honest, although that is probably mostly due to the axles being bent in weird directions. I plan to redo it this spring after I get a couple more tools.

Thanks DaiSan76 and would like to see the new look after the redo works.
FYI, I am working on my 2nd design. However, my 1st design's problem still slows me down as the failure in 1st design will affect my 2nd design. Actually 2nd design is replication of 1st design.
Back to our discussion on the boat making, I took my boat yesterday and now keep at home. No boat racing event at this time and many of the members are taking break so I better keep this stuff first for a while.
One thing that is still poor in this boat design is the base (where we sit the engine) still not really strong. The engine is just sat on the boat base and screwed on the wood and this can create alot of vibration when spinning at high speed. If you one day opt to use your gasoline engine as inboat engine, please ensure this is taken care besides aligning the shaft from the engine to the propeller. We had some cases before where the shaft bent (even broke) as well due to the sharp turning / cornering.
