Guess I'm ready for the Big Time! It's hard to believe that I'm really starting this project and I'm a bit terrified. I try to remind myself that this is technically my second build, since I made this pack when I was twelve...
Image Image
...but it doesn't help ;) I've read through a number of build threads, but I always end up getting lost in the details. So, I tried to just get an overall flow of the build process while keeping an eye out for any "gotchas". Luckily, I have some experience with breaking down large and complex problems into bite-sized "chunks", so that should help.

My goal here is to build a "Hero-esque" Pack, keeping the molded-in N-Filter, using the GBFans Shop shell and motherboard. Pack parts will be all aluminum and mostly from CPU64, with the Booster Tube from Ejgunth87. Since it worked extremely well for my uniform and belt gizmo, I'll be (trying) to follow in the steps of the always amazing bishopdonmiguel. He sets the bar really high and shows amazing talent, so hopefully I will at least get close.

The first "chunk" I'm going to tackle is mounting the shell to the motherboard, and all that it entails. I've already cleaned up the motherboard by filing the sharp edges and scrubbing with dish soap, water and 0-grade steel wool. Here are the before and after shots...

Next... attaching Ejgunth87's L brackets to the motherboard in a way that is compatible with Wiz's loom clamp...

Very excited to be watching this build. Based on your great Gizmo build, I know you'll be doing some seriously good things here... but outdoing your first build is gonna take some serious effort.

Thanks for the kind words, inspiration and support, Bishop. I have a feeling I'm going to need them :)

At the moment, I'm trying to figure out the best way to mount one of the lower L brackets along with Wiz's excellent Thrower Tube Clamp. I love the clean design and function of his clamp, so I'm determined to make it work with the GB2 semi-hero style shell/motherboard mount.

Here is a pic of the more-or-less ideal position for the clamp...
Image

And here is the L bracket in its more-or-less ideal position, along with an outline of clamps location...
Image
As bishopdonmiguel has shown, the above positioning can work with a slight modification of the clamp, but I would like to avoid the "overlapping rivet/bolt issue".

So that leaves me with the following position...
Image
Pros...
Clamp is in ideal position
Bolt hole can still be drilled in the shell in a "centered" position

Cons...
Bolt hole through the L bracket will be quite off-center (but not enough to matter, I believe)
Rivets on the bottom on motherboard will be a half-inch off from their ideal position

I can live with those cons, as long as I'm not missing something here :whatever: So, please feel free to raise any red flags or suggest other options :)

In my opinion, don't compromise on best bracket position. Consider taking a quarter to half inch off the bracket or address the overlap by dadoing the clamp . Those brackets hold your shell and you don't want weird angles, etc.

I'll go with best bracket position. It makes sense, now that you mention it - those positions were chosen for a reason :) To resolve any overlaps, I'm leaning toward dadoing the clamp and keeping the rivet heads close together. Thanks for helping steer me in the right direction, Bishop!

One thing you should try to take account of, which I failed to do, is the extra spacing required for the bolt/rivet heads. I made the holes too close and due to the large flange rivets, the bolt overlapped and I had to Dremel out a space to accommodate. You might set the rivets for the brackets back just a touch to avoid this.

Most certainly. I was trying to get at that with my "keeping the rivet heads close together" comment, so thank you for confirming!

Dr. Benton congrats on the start of the build. Unfortunately I have put a hold on my build for the slime blower for now. I'm in the process of still moving plus still crazy busy at work.

Thanks, Andy. I totally swear I won't hit you in the face with this pack :cool:

I ordered the loom clamp as well and decided to not use it for my gb1 hero. Trying to go as screen accurate as possible. I may use it for my gb2 pack or my other other custom pack I'm planning out.

Personally, I think the loom clamp is freakin awesome... but I do admit a bias. When screen accuracy and what I like come into conflict, the latter always wins :)

Very much appreciate the feedback, Chris! I'm definitely going to have the brackets properly placed, then try to modify the clamp to work around it.

I understand what you mean, Jay. Screen accuracy is a priority, but trying to take advantage of some subtle improvements where I can.

I've been taking tiny little baby steps, and I'm ready to share a small update...

I've positioned the L brackets, marked them and taped them down. Although you can't tell in the picture, I used a center punch on the brackets to mark where I will drill holes for the rivets. The shell fits snugly against the brackets, so I should be in good shape...

Image

I still need to get some materials to practice drilling aluminum and pulling rivets. Just got to make the trip to Home Depot :)

So, after a lot of measuring and thinking, I'm looking forward to actually attaching things together in the near future.

There's nothing better than the devil on your shoulder telling you to go faster but the angel on your other shoulder telling you to take your time. OH, THE CONFLICT! Looking terrific thus far brotha!

I had never pulled rivets prior to building a pack. Something that worked well for me was to pull the rivet until it cinched up firmly then release. Double check alignment then take up the slack on the pin and pull until it snaps. I was concerned a single pull might result in loose rivets. The double pull always created a tight hold.

Also, depending on your rivet gun, the grip trigger might have a safety on it. After each pull, you might have to pull the grips apart before sliding the gun up on the pin for the next pull. It usually makes a pop noise to get it out of the safety mode. I have a Stanley and also a DeWalt, both have this feature.

Thanks, Bish! I've found that your "double pull" technique has worked great on my practice rivets. They aren't hard to pull correctly, but you are correct, there is definitely value in practicing with these.

Ain't that the truth. Thanks, Grimmy!

^THIS^ - I was like, "How the hell do I slide this gun up the pin?" And now I know ;)

BTW, how is Ann Arbor these days? When I worked in Saline in the mid-90's, I would attend 2600 meetings in that little shopping center (with a Pinball Pete's in the basement) across from Middle Earth on S. University. A great town!

Aw man, Pinball Pete's was flooded earlier this year too. Anyway, A2 is doing great! It's constantly growing and expanding. We only moved out here last December so we're venturing in every which way to discover new opportunities. Saline, to my understanding, hasn't changed much in the past 20 years or so.
How did you like the meetings? I would like to go but would get all kinds of lost as I am not savvy in the department lol.

BTW, keep up the excellent work on the pack :cool:

It was a fun time and good way to meet interesting people. The highlight was when this guy showed up to one of the meetings...
