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..
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
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
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
so here we have the machine cut marks from Dev,
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
now we have holy cow shiny,,
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.
