Seats Manufacturing

·         Seat pan/leg pan/supports: cut from flat panels

o   Need calculations on how strong the panels needs to be (both with the supports and without) (thickness that the panel needs to be)

·         Back rest:

o   Pre-preg with an MDF mold (there may be a slight problem with the way the bottom that touches the floor needs to be cut (it is not a radii at the moment its very sharp but I think it won’t matter because we have triangular supports)

§  Need calculations to see how thick the panel needs to be

·         Foams:

o   CNC hot wire cutting for the polyethylene for complex concave (ask them if the wire will do neoprene there website does not say that this is a type of foam that they cut)

o   Foam to foam is A & E contact cement (used in cosplay outfits if it good enough for them then it’s good enough for me)

o   Foam to cloth is A & E contact cement

o   Foam to seat 2 part epoxy

o   Foam should wrap around the corners of the seat back and seat pan to minimize injury of having exposed CF panel that is sharp

o   Neoprene, High density polyethylene closed cell, and polyethylene open cell (also High density)

·         Materials/cloth

o   Mesh (backpack type)

o   Power mesh

o   Neoprene

·         Inserts

o   Plastic inserts (simple in shape maybe able to just use the machine shop) general shape is a rectangular prism with a rim

o   If we tweak the dimensions we could just buy them off the shelf

·         Ballast

o   CF for the flat panels over lined the outside with foam to stop sharp edges

o   Flat panels just cut and attach with epoxy

o   For the pin mechanism maybe glue another material up there so it has something to drill into (stainless steel pivot hinge rotation they cost about $30 for 2)

o   Attaching panels should still be epoxy

o   Hold the ballast box in the box with the mushroom/Velcro thingy

o   Next steps: How to hold the swinging lid in place???

      Next steps:

o   Get calculations for the seats thickness (for all components)

o   Start CAD for the MDF mold (with a question about how to do the bottom that touches the floor)
