So I’ve been hard at work building my pack. Got a shell from etsy, clean up went great fiberglass on the inside drilled and tapped, mounted things and glued/bolted some stuff down. Next step is mounting it to the [motherboard](https://www.gbfans.com/wiki/equipment/proton-pack/motherboard). But for the life of me I can’t get the sync generator to sit flush. I’ve checked the level over and over, sanded and dremel-ed away as much as a can. It’s entirely possible my shell warped when glassing is there a method for warping it back or should I stick with sanding it slowly back to level. When mounting will the motherboard bend to accommodate? Thanks in advance. I’m using Knowone Designs awesome shell by the way. ---

Pictures would help. Don’t think you’ll have a lot of success warping it back. If there is a gap, you can fill and sculpt with black Milliput. ---

I didn’t think warping it back was a viable option. Actually after taking pictures it’s the closest it’s been to sitting right. The left side with the cosmetic plating is the furthest and at it’s thin already. I may have shaved too much off. ---

I also found some answers searching around on here, just looking for another perspective. ---

I see what you mean. Some have used the “driveway method” to even out the shell. Basically, you set the shell on the concrete surface and scrape. The driveway acts like a giant sandpaper pad. But this can also chip the thin areas of the shell. Not familiar with this shell but I think Milliput (or Apoxie Sculpt or…) would be a good fix to fill in the gap. Might take a few sessions to get it just right. Apply from the back, thick enough to ensure a good bond. Extend the epoxy far enough fill the gap. On a surface with wax paper, turn the shell over and press down until the epoxy is flush with the surface. Let cure. Sand edges down with Dremel until you have a smooth outer surface. ---

Excellent suggestion! I can actually facilitate that fairly easily. I’m not too worried about chipping this thing is pretty thick even before I added fiberglass, but great idea. I will definitely try it. ---

I used a mouse sander with 80 grit pads and carefully sanded down the back of the shell that was hitting the [motherboard](https://www.gbfans.com/wiki/equipment/proton-pack/motherboard) first, bit by bit until my shell was sitting as flush against the motherboard as I could get it. It came out very well, especially considering I started with a 1/2" gap at the top right corner behind the HGA… ---

I’ve used thin craft foam or black window insulation strips to make a gasket around the shell. that helps even out any areas and allows for the possible flexing of the [motherboard](https://www.gbfans.com/wiki/equipment/proton-pack/motherboard) or shell. Just another idea.
