Creating the bigi71 motherboard

Soooo as some of you already know I’ve been casting up Proton Pack shells by the miracle man bigi71. I also want to be able to offer motherboards for all you fine people so today I undertook this little project.

First I laid out and taped together 6 pieces of 8.5 x 11 paper, then I made some markings so that I could line then up again after disassembling them.

Then I began tracing the shell out. I left about 1/8" of clearance all the way around, as you can see here.

Here’s the first pass after tracing.

I lined up an MMM mobo as best as I could to make the bottom two mounting holes.

Then I used an ALICE frame to line up for the third hole.

I traced the center bar of the ALICE frame and using some reference that I had I marked the third hole.

As you can see here I squared off all of the ribs on the side and made the right hand section connecting the gun mount to the sych-gen

Water jetting or laser cutting requires a 1x1" marking for size reference

Next I scanned in each page and lined them up again in Photoshop.

After that it was time to go to town on vectoring this puppy.

After a few hours I had this…

Next I printed out a copy and reassembled it again. Time to see how it came out :cool:

I compared it once more to the MMM mobo, take note of the mounting holes.

I also lined up the Alice frame one last time.

It’s a bit hard to see but the top mounting hole came out perfect!

Aaaand, here’s how it lines up…

Great success, yes!

Time to send this baby off to the aluminum cutters!

Nice Job You Did! This man needs a Crunch Bar!

EYYYY

Friggin sweet

How good would this sit on an Alkaline shell??? If it’s better then the one i obviously already have, i want one!!!

I don’t think it would fit an Alkaline shell very well at all. John’s shell was made to Stefan’s plans which is also how Irricanian’s motherboards are made, MMM is your best bet for that.

I only intend for these to be used on Bigi71 shell, it’s a custom fit.

To heck with Crunch bars. This requires a meal.

With Chicken.

Enthusiasm.

Dancing.

…and an excuse to use this gif.

Great jorb!

Oh you! :wink:

Beautiful work Vince! People are in for a real treat here!

Ooh, and when will they be up for grabs?

They already are :wink:

Ah yah, just saw that. Sorry.

Well if its still up for grabs next month. Here is hoping! Ima order one.

Maybe if the MOBO is done by then I can order in bulk! WOO

Looks great!

I hope you recoup the cost of all that black printer ink…

frigggin sweeeeet

Dozens of black printer ink cartridges gave their lives to bring you this.

Awesome though, nice to see another shell get a to-fit MB made for it, definitely eases getting everything together. Also helped me with my third hole dilemma - now to go drill one on my MMM MB.

Great work Vince! Cant wait to grab one :slight_smile:

Nice work Vince very professional.

Incredible work, man. That thing’ll be a beauty. :slight_smile:

How much and when will they be available? :cool:
