Billet Birthin' Update Jan 26th

first off, holy cow, cool vid Vapian.. thanks for sharing that with everybody, and what a beautiful kitty monster!!! I GOT A THUMBS UP SUCKERS!!! YAH!!! (thanks buddy)

ok, well last update the main bodies got all carved up, but we still had the slide covers to play a little more with.. now i know i spilled the beans early with the engraving, but heres how we got there… this is how the stock looked after the first round in Dev...

So we needed to machine the inside of um now,,, but the old jig that made the pre releases was 100%, completely shot… totally junked.. and really never worked well to begin with. It was supposed to hold the lids with vacuum, and it only "kinda" worked,,, so on some of the Pre Releases you may or may not have 4 holes on the inside of the slide cover.. (k everybody look now) I know Vapian has the 4 holes because i just saw um… the 4 holes were me giving up on vacuum holding and just mounting them into position with some brass screws.. well that worked but it's just not what i wanted,

I really liked the vacuum holding idea, i just needed to make a better jig… and get a stronger vacuum pump as i'm about 4,700 feet above sea level, it's a little harder to create a high vacuum up here. So the new jig started out as this happy little slab of mic-6 cast and ground aluminum.

and then i wrote some instructions for Dev to cut it in into this…

so after she cut that out. i installed this black squishy gasket material stuff in there, this creates a way better seal than my last jig did..

soooo now the slide covers can be set into the new jig (i haven't come up with a name for this jig yet, any suggestions?) and the little pins on the jig align into the little holes in the slide covers...

then turn on the vacuum pump… and they get super sucked down with about 54 lbs of pressure each..

some love taps, for the fun of it…. may not be necessary but i like to hit things..
DSC09772_zps0a8606fa.jpg


now Dev can start to surface the backs down to depth..

on a side note, i'm really happy with this sony dsc-v3 camera a bought back in 2005, I took both the picture above and below with that end mill spinning at 30,000 rpms and not even a blur… crazy..

k, they are super flat now…

DSC09784_zps6967b5e7.jpg


turn off the pump, they just pop right on out.

At this point i had to stop and write some (a metric ton of) code… as it was time to figure the engraving.. I tried a few different designs and had to make a decision about if we were going to fill the engraving or not,, if we did fill the engraving Dev would only have to make one pass over each letter to cut it, but if we left the engraving unfilled she would have to do 2 passes over each letter to cut it cleaner…. I made a cr@p load of tests and had to make a call what i liked best.. this is what i picked

DSC09851_zpsc846ee97.jpg


a deeper, double pass, unfilled engraving.

So now i have some slide covers cranked out, I'v been handing um over to my sanding and polishing monkey… He installs a temporary spring ball into the box and mates a slide cover to a body,, then sands, then polishes, then sands again, then polishes…again
DSC09838_zps2a4496c0.jpg


so here we have the machine cut marks from Dev,
DSC09839_zps2ae67f01.jpg


now this one has had all the machining lines removed, after 320 grit, then 600 grit, then one buffing round then hit with 1200 grit
DSC09840_zps1d13ac42.jpg


now we have holy cow shiny,,
DSC09833_zps38d0e7b0.jpg


So we have a lot of polishing to do (the buffer is way super messy to play with so hopefully i don't have to pick up any slack), I have over 50% of the pre order bodies and slide covers all machined and that will keep my polisher busy for the next week, the rest of the aluminum (like 450 lbs of it) will show up this week and Dev and I will pop out the rest. Now that all the coding is done and known to work as it should, all this goes much faster.. so that's awesome. So now I move on to all the plastic part stuffs, WAY quieter to cut than the aluminum… so that will be nice.

Any chance those made in the USA doors will be sold separately for us early BB owners?
Nope, yours is like a collectors item, rare finished prototype!, would go for BIllioNs on ebay. But, here is the real reason, I could send you a lid and it would work "kinda", but it would not line up great.... the reason your lids all line up absolutely perfect is because they are sanded and polished together.. there is no way to sand and polish one without the other, they are each mated just for each other to tolerances finer than .0002 of an inch. That is the one part of the billet box that is simply just not interchangeable...

thanks for the update doug! i'm surprised a vacuum fixture works with metal! I did the machine shop thing for a bit and we only used vacuums for plastics, but i donno bout what psi's we were using them under.

about that tank... it remind anyone else vaguely of a companion cube?


Indeed! ... My best friend in the whole world IS a companion cube.
