How to properly measure a yoyo

I have been noticing a LOT of yoyos are not matching their specs, specifically in regards to weights, so I suspect other issues are at play as well. I’m planning to buy an inexpensive set of calipers to measure yoyos.

For getting width, that’s not a big deal. I would ASSUME that is “width of yoyo WITH bearing in place”. Then I could measure each half(or one half and multiple by two), then subtract that from total width to get the gap.

I don’t want to spend a lot on a caliper. I figure a basic one at Office Depot or Home Depot or Lowes would get the job done. Getting an “inside caliper” is proving to be more expensive than I want to spend. I have a low cost 300 gram scale that goes to hundreths, and for my purposes, that’s sufficient.

Plus, I’ve been getting modified yoyos and I want to measure their new dimensions for proper cataloging into my database.

I have some calipers that measure inside and outside. They were actually not costly at all. I think it was 25 dollars at LOWES. Metal body and a plastic head with a LCD screen. Not costly at all.

Oh, that’s not bad at all. I’ll go hit them up next week. $25 is more than I was initially looking to spend, but yeah, that’s not bad. Does the inside calipers work good enough to measure the gap?

Oops, there goes the budget I was gonna use to buy some bearings from you! No worries, you’ll have more bearings for sale or there will still be some around.

I got this modified Hitman, and I want to get the adjusted specs.

An easy way to measure the gap is to use an automotive feeler gauge.
Just stack’em up.

That never even occurred to me. I think I need to think more outside the box! That kind of thing was way outside the box I was in.

Thanks!
