Fuel Cell Location Framing

So given I have a bit of down time to contend with I thought I would update on progress.

I have finally have come around to framing up where the fuel cell mounts.

This is partly to make the mounting more secure under lateral loads and to offer better fitment for the cell container and also to stiffen up the flimsy SWG20 panels.

The advice I had received from some one who works building race cars was that the alloy container could be drilled and bolted to the chassis.

This contradicts the fitment guidance specified on the ATL documentation which states you should not do this as the bolts inside the container could chafe the cell and lead to damage, possibly puncturing it. It also strikes me that there is something perverse about drilling holes in what will be a sealed alloy box. So progress so far:
