I need a PRECISION straight-edge, so I made three

Have you seen the price of precision metrology equipment lately? Neither have I, I've been too busy rubbing these sticks together in an attempt to find flatness.

If you were a Patron, you could've told me how silly this project was from the start.

I am an engineer, and on this one the project went about as well as I expected. The difference is I’d have kept honing until there was nothing left and you stopped at close enough. 😂

If I had a nickel for every time I found a channel with a charming aussie bloke making surrealist jokes about food and nicking stuff in public for projects, claiming not to be an engineer while doing engineer things in their garage or shed.. I'd have two nickels, which isn't a lot but it is strange that it happened twice. Subscribed.

you're not a filmmaker either, but those high off angle shots are becoming something of a visual signature for your videos

Always nice to see a non-engineer do stuff much better than an actual engineer. (me)

As a woodworker, I periodically reflect on how easily one can produce a straight edge with extraordinary precision using nothing more than a plane and feeler gauge. Simply clamp two boards together and plane their edges as straight as your plane can manange. Then unclamp the boards and put those two edges together, and check the gap between them with the feeler gauge. The gap between them is double the deviation from straight of each board. So with a .001” feeler gauge, one can easily produce a straight edge that is less than .0005” out of straight over its entire length, which is damn good for basic hand tools.

Lol. Dude went straight to steel after spaghetti didn't work after the first try. True engineers, like myself have been using the spahgett standard for months. Like our ancient ancestors intended.

the fact you actually used the 3 plate method and went through all the way is admirable

The bit with the panning back from the glove pushing the workpiece reveal was brilliant! Thoroughly enjoying the comical additions to these great vids.

The comedy in this is definitely spot on reminds me of younger "that old Tony"

Well you got a laugh and a sub out of me. Bravo for sticking with the project.

Dipping hot roll steel in acid does a good job to remove mill scale. Can be as weak as vinegar. Don't let it sit for too long or it starts to rust. I would probably rinse with distilled water after and quickly air/heat dry it after.

Ah, the good old 3 surface method... I expected nothing less... Also, nice seeing Alex mentioned... I hold a small state of him right next to the small statues of Stefan and Robin on my pedestal of machining excellence, supreme pedantry and dedication to precision...

I'm watching all youtube machining allstars for over 10 years. I'd like to say that your videos are great and keep them coming.
I made a precision gearbox - with NO GEARS.
