Don't know how to embed. Could someone do that please?
4 hours of the Professor curing your madness. Totally worked for me. Completely. 100%. Next deck I buy won't involve a maddening search for wheelbase and tail dimensions. Then second guessing my wheel size. Cast or forged baseplates
Extra treat?

Genuinely curious. Ive not had a chance to listen but what made it help you out with the dimensional madness we seem to have. I want a cure!
What?
You missed the part where he tells to how to pick out your ideal setup?
Gonna have to rewatch the whole thing
Nah, tbh it's all spread throughout the interview with him talking about physics and tuning to ppl's body type and skill level. What he says about Lee's wheelbase deserves some rambling but I think it'd involve talking about hip width and Q angles. Think it's Q angles..
And your *true* inseam, not the size pants you buy. What that's really trying to gauge is leg length from the ground to the pivot of your hip joint
If you're into math, physics, engineering this stuff shouldn't be groundbreaking but does serve as a great refresher and might even point out some stuff that you didn't think about. And hence the madness grows...
Was great for me cuz I got to see someone rabbitholing worse than me. I've measuring my wheels with calipers for decades and I'm just mildly curious
I've thought about using an angle finder like that to check assembled nose/tail angles but didn't wanna give into the madness
Also nice to know that the flexiness of modern boards is by design and not just cuz they got too thin. I don't recall Featherlights being weirdly flexy but I could def feel it with a Fiberlight
I wish he had talking more about concave and board strength. Everyone ignores that fact that some modern decks have spoon noses/tails and vexcave!
I love, love, love the Professor. Couldn't thank him enough cuz I absolutely loved PS Stix boards in the 90's. I'd skate them now but don't have any in the stack yet. And just listening to the history of what he's done amazes me. I can't believe how much he's done to improve skateboards. And it's frightening to think, "what if he'd never done all that for us?"
Thanks Professor!!!
That said I think there's a bit of a generational bias to what the Prof says. I was a grom in the late 80's, I can remember his Schmitt ad where he's riding a Yardstick and I think he's wearing a lab coat too. Guessing he was mid-twenties at the time? Early-twenties? He probably wasn't working on boned out melons or how may boards he could ollie, mobbed out fliptricks, etc. He would probably destroy me on transitions tomorrow but who couldn't?
So, ramp vs street.. old guard vs new school..
IMO, you don't need a *real* nose for a good ollie. Look at mid-80's Mullen footage before you argue that point..
What *I think* happening is you use the mass of the front truck as an "anchor point" and with your front foot in front of or over this mass you can leverage the back end up. Or you're just stopping the board's upward motion at the front while allowing it to continue at the back
Idk, maybe I'm not picturing the free body diagrams correctly. Totally open for discussion here..
And the thing with wheel shape.. I *think* he's talking about (polar moments of) inertia but the way he describes it makes it seem like he's referring to rebound (spring back) in the wheels affecting your flip. Kinda like how a tre is all in your back foot and the bushings help the flip. Or pressure flip..
Cuz the board being tippy when it's on the ground wouldn't affect a kickflip. Other than its lower moment of inertia cuz the wheels are lighter/skinner or set farther inwards. Been a minute since I had to talk geek, hope I doing ok
