Ever since I realized I was going to have to weld this chassis I've been making a list of all the repairs and improvements I would do that required fab work. The latest on my list was only added earlier today and I've already done all the prework. I was watching the gopower video about their...

Alright, not that I doubt you all but youtube is always a fun confirming device for me. Edit. I don't think I'm going with the Leaf batteries only because they are so large and while a good deal, it's way more capacity than I think I will need.

I've read over the sticky thread and can't get past figuring out the sin of an angle (I keep getting a negative number, lol). So this is what I know and want. My kart with me in it ready to go will weigh ~400lbs (less if I don't use heavy SLA) Want to hit 25mph speed. Will need the torque...

I'm new to welding and was thinking of using these bolts to fix my cut frame. I'll cut the heads off and use the bolt as a dowel. I'll also cut small slits in each side of the frame tubing and weld the bolt directly to that frame. Attached are pictures of my frame as it currently sits.

I'm telling, we need a database with real life measurements. :) A shared google drive spreadsheet would work well for storage and a thread dedicated to people adding measurements would be where the data comes from. ---------- Post added at 08:41 AM ---------- Previous post was at 08:38 AM...

So while I'm still removing old paint and preparing to weld it back up I'd like to order some wheels and tires. I don't want the massive means I have right now. I'd like some that are mostly for street duty and and some grass. I don't want a straight slick since I still need to climb up a few...

Lol, very true. So I sat the parts together to see what I can make out and this kart was definitely cut on purpose. I was thinking that maybe it had bent or broke, but nope. The cut the frame and the welds that connected the seat back to the rear end. Positive side of that is it will be easier...

Yeah, pretty crazy. But I guess the rear end is always pushing so the odds of it coming apart were low. So I measure the pipe and its around ~.72" and is a loose friction fit. The ID of the frame appears to be very close to .75" so I'm going to go for some 3/4" OD steel pipe or rod.

Okay, took a break and looked at the extending rods. They are solid and I believe they are brass so that's a no go on welding with those. Time to find some steel pipe to use instead. Also, turns out the full length of the rods CAN fit into the frame. No clue what the history of the cart is but...

Can this system get 350lbs of kart and driver up to 25mph while still having enough torque for 20 degree slopes?

The pedal bolts appear to be correct. They are shoulder bolts that pass through the chassis then thread into the pedals followed by a nut.

Got it broken down. Now I need to clean it and figure out what all is bent or broken. Like I posted earlier, the spindles are bent and potentially have worn down shafts. The pedal are bent but can be straightened. Question about those, is the shoulder bolt near the bottom supposed to be threaded...

Well that was easier than expected. Less than one minute of knocking the back bar and it came apart. So I just got to the front wheels. They had a lot of grease on them and on the axles and now I know why. So the wheels don't appear to have bearings but they do have zerk fittings. Also, the...

Can't weld yet but have watched videos of it for years. Always wanted to. I'll practice on some scrap.

An 1800w motor can move around easily move around a kart that big at 20mph?

Cool to find someone else in GA. I'm in Gwinnett County. Just found a rolling chassis that I will be making electric.

I had the same thought with tubes. I do have a small torch, but I also have a strong heat gun. ---------- Post added at 10:45 AM ---------- Previous post was at 10:44 AM ---------- I was thinking the same as well. I have everything needed for pre and post welding. Just don't have 220v to...

Any other tips for welding supports? I have to pay a welder anyway so I'll have them hit up everything. Also, did you sand it bare in that picture? ---------- Post added at 11:42 PM ---------- Previous post was at 11:40 PM ---------- I hope so, that's my plan.

I want to strip it down and repaint it also. Guess that's what I'll be doing this weekend as well as getting those pipes out and finding someone to weld it and checking all the bearings and such. It squeaks louding when turning the steering wheel. I guess I'll find the cause during the tear down.
