I do realize that a wall thickness of 0.5mm for Titanium isn’t uncommon. Like you said though, the fact that it worked so well in 7075 is still crazy to me.
Do any companies do shrink fits? I don’t know if I’ve ever seen or heard of it except for Onedrop.
0.5mm walls are uncommon in the yoyo world, where most go 0.8mm or thicker which defeats the purpose of using Ti in the first place, where the efficiency is similar to 1.2mm 7068 aluminium when you try to minmax moi. Having thin walls make it prone to errors during machining and vibe, and given how picky people are with vibe these days, manufacturers are less inclined to do thin walls where b grades happen more commonly, especially when the average player won’t be able to notice the difference in play you get from the minute advantage you get from using thin walls.
There are other companies doing thermal shrink fit, but it’s uncommon. Hydrangea and Yoyomonster have done 0.5mm wall Ti yoyos and thermal fit designs, but since they’re more prone to vibe, people tend to downplay their performance once they get vibey yoyos out of the box. Their yoyos undeniably have the most efficient design for their weight though.
I think one of the big issues there is the fact that the majority of manufacturers cut the cup and profile in one go. It’s WILDLY more efficient than how I have to cut them, but also considerably less stable when stuff gets thin
Really? Other than the added calculation and the mildly increased risk of worker injury it’s so much easier to do… I’d think it would be super common, but we’ll have to see how my attempts go I guess. I could be talking out my butt on that.
SO MANY WIRES.
This is only the barebones setup, too. We’re gonna have to run MORE wire when we get the second panel installed. Oh and we are gonna need to add a third panel as a subpanel dedicated to the machines themselves at some point because we will otherwise have too many individual conductors in the wireway to be up to code. When that happens I’ll be needing to rip out all the wiring I did into the pallet racks to reverse the lengths 
Going has been slow because I’ve just been wiped at the end of most days, but things are coming along.
at least you have a race to pull through instead of conduit! eff long conduit runs
I mean there’s a bit of conduit. Tight corners and a ton of conductors make that a little annoying…
My current puzzle is crimping all the 3-phase legs, grounds, and neutrals together and then trying to figure out how the hell I’m compacting them into this tiny box so that the switch still fits in there. Last box like this, at least.
Almost as annoying as pulling the power through the lab sink cabinets…
We ended up working with fishing line and going through the structural cavities in between the sheet metal pieces. That was annoying.
can you not use split bolts and just put a box extender on?
Too many conductors for a split bolt per code, and my boss wants the boxes to remain low profile 
Crimps are the way to go. Lots of wires though. Packing them into the box is a nightmare.
ah i c, and and yea packing j boxes is almost an art in itself
Looks like we are now running wires to a separate box specific to the switch. Gotta mill out a few more face plates, but it’ll simplify SO many things.
so i was drilling a 3/4” hole once in a box lid for a cubicle connection and long story short, factors lead to me losing control and the lid grabbed and spun out and chopped my knuckle and cut right through my glove slicing it straight to the bone 
at least one “factor" was totally my fault, but i can tell you i never made that mistake again. commercial electrical supplies almost seem like they’re TRYING to hurt you sometimes 
LORD.
I’ve cut myself pretty good and deep on titanium chips while trying to pull them free of the spindle in the past, but I’ve lucked out on drills grabbing and stuff so far.
new boxes should make cramming wires into stuff a lot easier. In any case
Ok. Finished with the wiring for now. We can’t run every machine at once or we’re gonna start blowing fuses in the building (there’s actual fuses outside) but I can get the mill and lathe running simultaneously. The solution will be to eventually have PG&E upgrade the transformer out at the street and have them run extra copper to the building panel so we can have 300A in our unit instead of 100A. We’ve also got plans to add 2 more panels. Stopgap might be to ask the building if we can take over the 100A in the house panel that runs things like the exterior lights. Dunno exactly what it’ll be, but for now I’m good to go.
I also got the laser marker up and running with the new power, though it seems I have a cooling issue to chase down. I think I might have fixed it already but I’ll need to test it again. So far I’ve I only tested it out on my phone case:
I also thought people might wanna watch paint dry, so here’s me setting up tools in the lathe so I can machine some Queens.
Making titanium yo-yos seems insanely expensive
Luckily I don’t have to deal with that overhead because my day job did the groundwork for me.
In terms of process time, I do have to say these are rather expensive. If I had a different machine, or a machine I bought specifically to turn yoyos, it would be a very different matter there.
That is a beautiful site to see 
Just wish it wasn’t so late 
Drool…
Are there final stats on this yet?
