I decided to do a tabulation of wheel bearing sizes for my own reference, probably not exhaustive, but at least a good start. This thread seems the best place to share it.

Good chart Chris. Like a lot of guys here I'm sure, I've had all those number
but they're scattered all over the place. Thanks for lining them up in an
orderly manor.
Only problem is......all those dang M&M's! Think I'll redraw my copy with some
numbers in med-western USA speak, you know......inches.
You would think after 75 years of working around machines and spending a few
decades as a Sr. Research Technician and incoming parts inspector at a
National Accelerator Laboratory with Physicists from a hundred countries......
that I'd be able to "think" in metric.
And...thanks one more time Chris.
G'day

You don't need to convert them Denny, they're in ascending I/D size order for each O/D, and metric bearings are only any good for metric shafts. I was taught both systems, though like you I find it easier to visualise things in Imperial measurements.

I have fielded a few questions about my wheel design recently and so I thought I would create a new animation of the wheel design that can be found here:

And I added an update to my journal that summarizes the journey:

Great choice. I grew up in Indy; nothing like the sound of the Novi or the stirring looks of any Frank Kurtis creation. Remember seeing Chet Miller and Duke Nalon drive them when I was very small; later Russo, and finally my all time favorite Hurtubise in '60. I am considering a cyclekart project inspired by the Mauri Rose driven Blue Crown Special.

This entire thread was fun to start from the beginning and go through all the posts. It was as inspiring for me as it was when I started.

Just noticed an error in my bearing tabulation, I included MR1905372RS under 35mm bearings, of course it's a 37mm one. I've failed to find a 3/4 bearing in 35mm O/D. Corrected tabulation attached below.

The K3 is the perfect shape for a cart, and the drawing you provided tells a huge story.

I've been meaning to post this rough sketch for a while, just a thought that may help those struggling to fit an exhaust inside the body. No dimensions sorry, don't have an engine to measure them from. The round tube should be a sliding fit in the square, welded in place, and fillets welded inside the square tube to fair it in to the round. It's not ideal from a flow point of view, but shouldn’t be too bad.

Just to update the wheel / bearing info, I've been looking at Honda Innovia 125 wheels. I initially discounted them as they use 32mm o/d bearings, but on further investigation I've found these bearings are available in 17, 20, and 25mm bore, which changes things. The fronts use 32mm both sides, but the rears use 32mm one side and 37mm the other, 20 and 25mm bores are available for both. So here's another update on my bearing table.
