If it ever gets off the ground it will be something.
I am considering contracting some of the work out. The main thing being the thicknessing and then the bonding of all of the laminates. Although I could farm out the thicknessing by itself and bond the pieces at home, it leaves room for mishaps that way. Jack's daughter's partner is a cabinet maker in a commercial workshop and back at work with social distancing. I will see if his firm will quote for the job.
None of it's going to start without some sort of plan and the ideas are only just coming up to boil.
Like yourself, I will need to do some 1:1 scale drafts to help my ideas to crystallise.
