After I struck out with the steering, I moved on to front shocks. Its just tacked in, but looks pretty good.

I started messing with the motor mount, but after moving that heavy gorilla back and forth it wore me out. Ha.

That is some really sweet work on the front suspension! What size tire are you planning to run with?

The plan for now is to keep those golf kart tires on the front. Once its complete, I will upgrade the back to a larger size.

Well I finally managed a few hours in the garage.... this project seems to have slowed down, but the weather is starting to warm up and my interest has not faded.

I purchased another steering set up, I should get it from the mail man tomorrow. I went with a 14 aluminum rack and pinion fom Amazon for $100. I just hope it works. I still have to buy and assemble the tie rods, but figured Id hold off till I have an exact measurement.

I also bought (2) 5/8 pillow block bearings for the steering shaft and universal set up. I got those yesterday, and Im happy with them for $8 a piece.

I did get to mock up the jack shaft and calculate where the engine is going to sit. Its not permanent yet, but here are the pictures.

This picture was my first attempt, but I discovered that I want the sprocket on the drivers side so I switched it all around. It does not look like this now.

I'm curious to see how the steering comes out.
I have a granddaddy (purchased second hand). Live Axle, Wide Rear Tires. I messed around for a while trying get better "Ackermann" geometry. Slow speed turning still sucks unless I am spinning the tires. LOL. At least I don't think I have Anti-Ackermann, which I think I had before (if that is even possible). My outside wheel used to just act like a plow. LOL

Id love to see some pictures of your kart. Do you ride mostly on dirt/grass or pavement? I currrently only have the key on one hub. If I plan on riding on dirt/grass Ill add the key to both hubs.

I hope to have some more progress on the steering come Monday and Tuesday.

You can see the offset on the YerfDog steering rack. Both are sitting at the neutral point in the photo. The new one I have has a longer travel also.

Well I got to play again yesterday on the Kart. Lets just say it was an educational day. I managed to secure the seat, pictures below. I worked on installing the steering. I was hoping the two units would be similar enough that I could use the tie rods from the YerfDog unit. They were not. The Amazon buggy unit has a heim joint thats threaded on, the Yurfdog unit has a ball joint that appears to be pressed on. Ill have to just measure and order custom tie rods online.

The biggest screw up yesterday was not figuring in the direction of travel of the steering unit before I secured it. Its BACKWARDS! I turn the wheel left, the kart will turn right. I hope to correct it today or when I return back to the house early next week.

So, I managed a few hours in the garage. I have an idea how to attack the steering. These pictures resemble what Im shooting for, but I drilled the holes on the wrong side of the shaft. Id like the bearing on the other side. I intend on fixing that today.

I am not happy with the amount of foot space, Ive decided to cut the weld on the front main frame right at the sides and add about 12. That will be a project for another day.

That inverted steering could have happened to any of us.

What stops the steering shaft from pushing forward? Why I ask is it could be an opportunity to add some crash absorption into the mix. Maybe just a collar set screw on the shaft. Enough set screw tension to not move when pushing and shoving on it, but should your body hit it during a wreck, it would push that screw/collar up the shaft and left the steer wheel push away from you.

For the steering shaft, I love that you have used bearings. I am about to convert my older yerf dog in a similar manner. It's a 5/8" shaft, so I am going to use cheapo wheel bearings and then a $5 pipe from the hardware store to attach it to the frame. Slide the pipe down to about 1/2" long, weld that to the frame, and then slide the bearing inside of it. I already have a cross bar support up hear the steering wheel.

Another option for me and others is to use a nylon insert into a set screw collar like so:
http://scenic-shop.com/wp/2009/11/weld-bearings/
When the nylon gets wore out, just replace it... so buy a 2' long piece of it and cut into sections as needed.

One thing to consider is that if you have a passenger they will not have anything to hold on to. Where as you'll have that sturdy steering wheel to grab hold of. Maybe a roller coaster bar that folds in! haha.

here is a beafy collar with set screw:

I cut it apart tonight to lengthen the frame around 8. It feels much more comfortable sitting in it at this length. Ill weld it back together tomorrow.

I finished one side, I may get the other side finished later today. I inserted 1 square inside the 1.5 main frame and plug welded it. Its not going anywhere.

I received these tie rods in the mail today from Amazon. I need to shorten one side another 1/2 or so, but Im happy with how they look.

I think I ended up making my own tie rods using 3/8" grade 8 threaded rod fit inside some 1/2" steel tubing. The ones that came on the buggy when i bought mine got pretty bent up.

Male Rod End / Heim Joint / Ball Joint
Grade 8 3/8" -16 TPI 1.5" Long Bolt / Nut
Clevis Joint (Had to be widened from .450" to .500 inch to fit the ball joint? I used an angle grinder)
Grade 8 3/8" Threaded Rod 12" long Housed in 1/2" Plain Steed Round Tube
Female Rod End / Heim Joint / Ball Joint
Grade 8 3/8" -16TPI 1.5" Long Bolt / Nut

I imagine you built yours for a fraction of what this kit cost. The part that I was unsure about was the Clevis joint having to be widened from .450 to .500. Every website I looked at sold the same one. Apparently there is no clevis available with a 3/8 bolt hole and an inner width of .500.
