Thread: New composite seatpan

  1. #1

    New composite seatpan

    Finally had time to put this seatpan together. Pretty wild effect with the 12k spread tow carbon fiber surface. The process used on this one also eliminates the need for plastic trim around the perimeter. Nice clean result.

    Maybe some day I'll do the backrest and footplate to match.

    Sharp!

    Did you make that yourself?
    How much in materials ?

    Tips and tricks you'd pass along to a novice, who one day dreams of doing this...

    Beautiful! I'm curious about your hand rims, also.

    Thanks! I'm pretty happy with it. Kind of a shame that it's almost never visible.

    The chair, handrims, etc. have been discussed on here in the past. Search for username Black Alloy.

    Material cost for an item like this can vary widely and the process equipment isn't typically something that most people will have access to. A seatpan like this is built from structural foam cores, various reinforcing fibers and epoxy resins. Molds and process equipment can range from thousands to tens of thousands of dollars.

    Here's a video of how part of this seatpan is made:

    Does your seat pan flex ?
    Recently found out that, solid seat pan can not be too solid, or else it hurt my bottom.

    sowseng,

    This seatpan does not flex. The frame of this chair is also built to prevent the seatpan from flexing.

    Using a solid surface seatpan like this one makes it very important to use a good cushion.

    I've found that the combination of a very rigid frame and solid surface seatpan provides better posture control than fabric sling type cushion supports.

    Yes, I have three chair.

    One with plywood, quite hard.

    The second, aluminum, when sit on, it will bend a little, just nice.

    The third one with fully welded aluminum seat pan, hard like a rock, hurt my pelvis so much.
