I like this a lot. I'm not a fan of logos. Unless they are a sponsor, I wouldn't put them on.
This Radio Flyer logo is cool - it's a big boy's toy.

Looks sweet how about dressing up the wheels with some baby moon chrome caps

I found this last night. I have actually been looking for a pit kit for a while.
I am going to do the same thing.. I race bikes so a little different arrangements... Have you drawn out any plans?

Those are the best builds. You got a cost total in your head?

Any race car related costs, I don't like writing down...

my dad asked my why I keep a log of tire pressure etc etc but nothing about how much lapping the 911 costs..

my reply was : first rule of fight club is you don't talk about fight club
same goes for lapping. First rule of lapping is don't talk about money.

No doubt. The amount I spend on racing can never be recovered, but there's hardly any of it I regret. Can't take it with you!

words of wisdom right there. That's why he thinks it's ok
sorry to hijack the thread, figured between updates we could bump it up to the top

I looked at them the day I sold the race car. The ROI is not pretty.

You checked the wrong file, I'm sure the ROI in the fun file is pretty great!

Very nice build and great show of skills. I read up a little on pit carts but I am confused on how you get them to the track etc. Do you load them up on a trailer? If that is the case, why not integrate the two into a pit trailer of sorts?

Portability. Closer to the car.

Your cart is truly a sight to behold. It's so well thought out and organized. Two questions-
You may have discussed this already, but is the winch 120vdc or 12vdc? Also I'm no electrician, but why use a watertight outlet, but no watertight flex hose conduit and connectors?

This thing is tuning out killer
Spent today working on the brakes. Sorry for the lack of pictures, but I was working non-stop trying to get things done.
I started by cutting out two "rotors". They're made of 3/16 steel plate. I cut the outer diameter with a bandsaw, and the inner diameter with a hole saw. Cutting two rotors took about two hours. On the plus side, I did it with material on hand.
After that, I clamped the rotor to a 1/4" plate, and the clamped the hub on that. I then mig welded the rotor to the hub, taking care to keep the hub cool, and peening after each small weld. I obviously wouldn't do this for a "real" braking system, but this is a fairly low stress system so I'm comfortable with the welds.
After welding the rotor to the hub, I put pads in the calipers and placed the caliper on the rotor. I used some compressed air to push the pads tight to the rotor and made a caliper bracket out of card stock.
After that, I transferred the template to steel, cut it out, and welded it to the spindle. I then painted the bracket red with rustoleum, which matches the powdercoat almost perfectly.
I'll try and take some pictures tomorrow of the system all put together. I mocked it up with a wheel and bolted it all together to verify it fits well. I had to gently sand the top corner of each caliper to fit and there's very little clearance. I'll take some measurements tomorrow for brake lines so I can order the materials this week.
Should be on track to have the toolbox back in the box and everything on the ground by the end of tomorrow.

Thanks for the reply above.
I just assumed the rotors came with calipers. Fabbing rotors is not something I would have thought to do. Pretty cool Pretty cool you're making your own rotors [emoji106]! They're no doubt much beefier than my original mountain bike component suggestion!

Looks like the protected outlets would be a good idea where they are located so nothing accidently gets pushed into them causing a short.

Duncan, I want to see your cover done. I went to Wally
World and got some cheap red and black material. I made two panels out of the red and a strip of black. I sewed the black as a mddle to the two red panels for my welding cart. I need to get a picture and post it tonight.

More terribly lighted camera phone pictures. Sorry for the fuzziness. I'm terrible about taking pictures as I build so I tend to only shoot at the end of the day (in poor light)
Mounting up the hubs
Caliper mounted. You can see the clearance for the wheel. If I had made the rotor about .25" smaller, this wouldn't have been needed.
I put a lot of tape on the front of the frame to stop it being scratched and then slid in the toolbox. Big sigh of relief when it fit perfectly.
Storage behind the toolbox.
Row of tool cases. I might make some fold down aluminum doors for the front. Not sure yet. You can also see the winch controller and its hanger.

Terrible picture of the finished cart. I promise I'll take a better one during the week.

In the above picture you can see the pry bar/screwdriver rack, and also the shop towel holder I added.

Ok, I just went out and took some better pictures.
Rear storage area of the cart.
Winch controller.
Tool cases all in a row. And my jump box.
Brake master cylinder. I had to make some modifications to fix the larger diameter handle.
Another shot of the brake handle
Towel rack and can holder. I moved it from the trailer door.
Bought some Wright socket rails to organize my sockets. Expensive, but they are nice.
Closed.
And open.
Anti fire bottle.
Rear bumper and winch.
Rear cabinet. I ordered some more shelves, but they're on back order.
Front suspension and brakes.
Front hub and caliper.
Positive lug for the winch.
Negative link
New work bench top.
Cleanup making progress.
