Oh man, if you're going to be offering colors, I'd really, really, really, really, REALLY like orange. Or green.
ok
'nother uPdate...
K, so here's the "what comes next" update... i'll fill ya in on what's been going on so far with the anodizing... first off, this is not as simple as get a box and hand it to an anodizer... so if anyone was considering stripping a BB and giving that a go, the results would pretty much suck. The reason this is tricky is because of how tight the tolerances are for that lid to slide all happy nice into the main BB body. We are talking +/- 0.0002 here
(aka: small)... The anodizing eats aluminum and then grows a layer of super hard magic growth stuff... Soooo, when you give something to an anodizer your part could lose or grow +/- 0.0005 per surface... as that slide enters a grove in the body there are 4 contacting surfaces, with a total probable error of +/- 0.004... that won't fly. So we test... and test, then test more... then one more time to be sure... luckily the anodizers are super mega willing to work with me here... but out of the few dozen we have tested with, i would only call 7 of um sell'able
(aka: really damn good). One of the problems here is that they (the anodizers) have lots of different ways to hold different shaped parts, but none of them are truly ideal for our parts, and that results in some rough handling on there end and dings and such that i won't let fly, i'll scrap the part... what makes it quite a bit worse is the amount of attention we give to mating each lid to each body... once they are paired they become one part, sanded and prepped together... so lets say the anodizers are racking our stuff and they drop a slide lid and ding it... then pick it up and rack it anyway,, now it won't work and we throw away the lid
AND body, over an hour of machine time down the drain... there is just no saving either after they are anodized... that was the case in quite a few of our test. They, and any other anodizers are very much a production setting, they need processes... the bottom line here is that we don't want them touching our shít! We want their acid, electricity, and science,,, we don't want their hand work. So we are taking that away from them and racking our parts ourselves... so what i have been working on for the past two weeks is to engineer them racks that
WE will fill with our parts so all they have to do is dunk them puppies in their happy acid vats of doom!
Sooo step one, design a racking system...
one to hold the bodies...
and one for the slidey lid things...
K, so this was kinda lame and i wasn't really camera happy makin' these, it was more a matter of cutt'n um up really fast and gett'n this over with... so i machined up all these ring / doughnut looking things, and these little post doobers that stick into the doughnuts..
I had two options for fixing the post to the doughnut, as there are only two materials that can go into an anodizing vat, aluminum and titanium. So i could use titanium bolts to mechanically fasten the two together, or i could have um' welded into place. I
HAVE to use titanium screws to mount our BB parts to the rack after it's done, and that was... well, here's a picture of my hand, holding 380$'s worth of titanium screws... apparently these things only grow on the now endangered titanium screw bushes along the ridge line of the liechtenstein alps... protected by goats... and dragons....
Yah,,, welding seemed to be the better choice.. so I'm having one of my neighbors round our new shop weld um up for me as i don't seem to own a 350amp heliarc welder
(it's on my birthday wish list)
looking pretty good, one of those titanium screws will now go through the electrical room of the BB and into the post on the dognut..
just another pic of it all done...
so that's that done,,, now we need to hold the sliding lid thing.. again, not trigger happy with the camera but i got the sucker made and that's what counts...
I just finished that up friday so i'll have it welded up this week... here is how that titanium screw is going to hold that slide cover in place.
another thing i have decided on is that i'm not going to give them to the anodizers engraved, this is the orange one i have been using for the past ...ehhh, 2 months round 'bout...it was engraved before anodizing, it looks good but...
i like this better,
so after they get back from anodizing i'll stick um back in... probably Ruby for this.. and she will engrave um...
K, so all that said and done, we still have some work and finger crossing before these become a production thing.. but i do have the end result in hand and have been using it for a good while now. The verdict is that anodizing is great for the Billet Box, it's tough.. aside from a very small ding where i drop an er32 collet nut wrench on my box, after 8 weeks the thing is still pristine... sure i haven't been throwing it across the shop to demonstrate it's durability... but still, my boxes don't have an easy existence, she has been picked up and set down on metal surfaces countless times, dropped on concrete
(which to be fair is epoxy coated so it's not as sharp as bare concrete, but still...), been put in my pocket with my keys, and the finish is still perfect... and it's orange, so yah know, awesomeness.. at any rate i'll be posting progression as we roll along...
think that's all the updating i got in me for the present...
