I managed to finish cutting out the two bulkheads.

Thats the thickest piece of ally I’ll need to cut for this build so glad the blade held up!

i also got myself an angle grinder to clean up the edges. I am really pleasantly surprised at how well the flap disks sand it down.

next up is the long horizontal bars which will weld to the bulkheads. Four of them at 3/8” so gotta keep up the momentum!
