Warren, the upper mold l have is one piece. The lower is L. & R. halves (bolt together) and i worked for-ever on the rotisserie. Thought it would never end/:) But you know some projects in the shop go smooth and quick, some have ghost!

Oh, you are wondering about the layup schedule. Is it going to be monocoque or using a frame?

Oh! l know layup schedule. You set around and think of it, great brain exercise. And l know people in the bizz who help me.

Frame of metal is a dirty word/literally. (my family started machine and welding company 35 years ago). I have welders here too but its very dirty. Shop is so clean without any welding. Thats why l love carbon fiber unibodies. I dont even paint (l roll on 2K primer & wet sand w/soap & hot water bucket). My velomobile want be painted, it will be wrapped. I could spray some accent stripes but that can be put on 52" printer @ wrap shop. Frans (pterovelo) suggested l wrap, l agree. No mess or overspray & quick and clean. Pick up velo finished same day.

IMO, Nowadays l like to use the word unibody for a carbon unit. Monocoque/or monocoupe as they say in usa is more related to older method of airplane building with a bucket of rivets and many pieces of aluminum that use each other for strength.

A modern cf lower shell mold (DF image) makes a one piece unibody as in pic below: Also ,, Earle Macpherson, chief engineer at chevrolet in 1945 design the macpherson strut that goes in this unibody front wheel wells. Thank you Earle.

My upper mold below is not needed till october or so:

Ha! real happy with duratec: l sprayed the rear wheel well plug today with it. Will help in the future. Sands like a dream after 2 hours. When finished, you can buff with the 2 compounds for a gloss. Should make a good 2 piece mold. l will look like amature instead of novice. Oh yea, iam pretty good cleaning gun.
