Gb1 half moon spacer you say? what is this guy talking about! ... here are some example snapshots of it from the film.
And last but not least... Egon doing the lift shuffle
Quite a while ago I noticed Chris Bosh's build had a different approach to the centre mounting spacer...instead of a squishy half round ball, his looked more prominent and rectangle.
I contacted him about it and he kindly filled me in on some info he had regarding the halfmoon spacer as well as measurements to make one. Chris's spacer basicly consists of a 3/4 thick block of wood or resin shaped into a half moon.
The advantage of this method is its far easier to create yourself and is quite structurally sound. with 1 inch spacers and washers on the bottom mounting screws, the 3rd halfmoon spacer allows the back to sit quite straight to the Alice frame.
Is there anything to back this method up? Not really anything I can show, but I have seen some images of the murrary Minnesota pack from behind. Where the 3rd gb2 spacer connects to the motherboard is a unpainted block of raw aluminium the sameish size to chris's measurements. It looks like they installed this spacer then sprayed the motherboard black, and when it was removed it left that tell tail unpainted rectangle behind.
Here are a few shots of it on my pack
I am in no was dissing the squishy ball method as it works just fine, nor am I Saying that this is definitively accurate and set in stone.
However I personally believe chris's method to be a wee bit more accurate having seen the rear murray pack pic.
regardless it gives us yet again more things to discuss...Yey!
Special thanks to Chris for allowing me to share his measurements with the community
