I think what's most impressive to me, is that beyond the immaculate craftsmanship and aesthetics of the objects in general, you also managed to design an entire maze, in 3d, on a *cylinder* and then just kinda glazed over it entirely like NBD.

There are tutorials for it. You just generate a maze on a website, import it into your chosen design software like Fusion 360 then wrap it around a cylinder.

my machinist teacher only taught us Single point threading and it was maddening. But hey now i know it!

[@Lukey-ts2xv]

it's an achievement? We learnt how to do it at Tafe this year, not quite a year and a half into my apprenticeship and i thought it was really easy. Only difficult part was trying to measure it using the 3 wire method, that shit can fuck right off lol You can tell by the thread angle when you're getting close anyways so i will just take light cuts from there and keep testing with a nut until it FEELS alright.

[@turtlemaster872]

Tip: instead of making 8% tin bronze, 10% aluminum bronze is notably stronger. Also, using water to cool them down quicker like that actually makes them softer. The screws still look beautiful, and I'm sure there isn't really a problem with softer metal, since it's not undergoing much stress at all.

[@juliagrauel2951]

Water cooling softens the metal? Annealing it? Oh right! So you can hammer it some more.

[@juliagrauel2951]

But aluminum has an extremely high melting point, does it not? We cast some at school and had to add an extra blower and coke to the forge to increase the burning temp like Carnegie did to purify his steel!

[@turtlemaster872]

​@@juliagrauel2951 I know aluminum has a lower temp than copper, since I can melt aluminum in my home foundry, but copper takes a lot longer. From a quick google search, copper is 1,085°C and aluminum is 660.3°C.

[@niptart1275]

Ive been a machinist for 23 years. This was beautiful machining my guy. I wish my first time threading single point went that well, pretty sure I scrapped my first go at it because I had my lathe set up wrong lol If I have any advice at all to pass down from watching this beautiful masterpiece you made, it would be to use a reamer instead of a boring bar any time you got the chance. Its a much better finish, and far more accurate than boring bars. Plus lets face it, those really nice mechanical boring bars that are actually accurate are very very very expensive lol(even the Chinese ones), like 2+ grand easily. Only down side to reamers is that they only come in certain sizes like 1/4", 3/8", 9/16", 1", basically standard common sizes, unless you custom order them(expensive). If you can use a reamer though, the surface finish, and size accuracy of the hole is gorgeous. A decent reamer has about a +/- .001" accuracy, so they get you super close, and they aren't very costly either. If you've never used a reamer all you do is make your hole about .010" - .015" under size then go in with the reamer, its that simple. A decent reamer set wont run you but a few hundred, maybe even cheaper if you buy them used. They are fairly easy to maintain, and last a looooong time, as long as you aren't expecting them to shave off .040" or some crap and you put them through hell lol Its mind blowing how far machining has came since I started. Lol hell when I started out about all we had was a file and a lathe and a mill lmao God bless!

[@hxcadillac]

This is such a cool project! Question from an aspiring amateur machinist: at 04:31, the bolt is protected from the chuck jaws by wrapping it in a metal sheath. That sheath overlaps itself a short distance, so that there are two layers of that metal between one of the chuck jaws and the bolt, while the other jaws appear to only have one layer between them and the bolt. Does this additional layer of material affect the precision of the lathe in any way, e.g., situating the bolt off-centre on the lathe by the thickness of the metal sheath? Or is this something that can be corrected for by individually adjusting the chuck teeth? Thanks to anyone that's willing to provide some guidance!

[@Twitchy239]

From what it appears, you could adjust the other jaws to account for it. However, we are probably talking of a 1/1000 shim (0.001 IN) so it would be a negligible difference for the accuracy you need on a project like this. I could be wrong though.

[@hxcadillac]

[@hometownmedic7355]

My guess is, if he fairly valued his time, energy use, consumables, and so on and charged a price that resulted in a profit large enough to justify what must have been dozens of hours; he’d sell the same number as he is now. Very, very few people are willing to pay for bespoke quality, and he doesn’t have a manufacturing facility(of scale) so he’d be making each one by hand. Or, he could outsource the production to china and get the unit cost down to a few dollars per(if ordered by the thousands) and he’d probably be unable to keep them in stock for awhile.

[@yksnidog]

Nice one. Just a no handcrafting man here who's interested in puzzles. I like the logo like impregnation on the screw nut of the old one. This would also add to the new ones. And the round bottom of these two could hold some Jumanji like text which lures you into the maze. Could be something like this: "Holding this in front of you makes a more stronger you. But giving it some twists and once or twice or more a turn could help to start your brain burn, old energy within your body's corners to find an escape from this transformer..." ;-) But what's not so nice for a puzzle solver is that this is a one time pony. Maybe it is not too hard to make a maze holder containing 3 or more of these maze roles which than could be interchanged with one another or more ones you could make in the future. Like a long screw with 3 or 4 or 5 nuts on it. These just have to have something holding them in place when attached to each other. They could also be different materials/colors/themes/... . Same goes for the screw nut to solve the puzzle. You can imagine it a bit like the hero going into the maze. So beside the maze line logo of the old one one side could hold a hero picture like a tiny Mega Man or the Transformers logo or the Zelda Triforce. So multiple nuts mean multiple heroes to choose 1 from before you start. And another idea I have is to add a hat with a screw for this so the screw nut can only go back to the start at the bottom until you twist the hat until it is removed to change the hero/screw nut. You can use all this inspiration for free but maybe I will do something like this in the future myself. ^^ Or more precisely: Let it be done. 🤣
