Nice work bmorr. How did you attach the walls..and I love your catwalk braces all this time iv'e had issues figuring out how to make them, never clicked they are just triangles lol. You have to decide first what kind of warehouse it is...is it a abandoned warehouse, if so everything in it wont be neat so you can have pieces of wood and such laying around...think Netflix DD scene with the Russian.
Or is it in use.. then it would be more organized like you pick...from there it gives you a idea..like is the railing broke..is it complete etc..after some trial and error. the easiest way to make the rail..make it like a ladder..then..cut small slits into the flat walking part, slide one side of the vertical rail into the slits made. secure, so you only see the top long rail and the verticals. the other long horizontal one is underneath. if that made any sense lol.
OHYEAH
Where do yo grab your foam core from and about how much does it run ?
