    NEW HOMEMADE SEAT FOR a CM400T

    Maybe should put it in the "What did I do to my Honda this weekend...thread" but couldn't find it...
    SO,
    I got tired of the look and design of the old replacement handmade seat I bought the Bike with,
    which a few days ago even cracked in the middle (crack visible from under the seat)
    so decided to take a go and make one as I imagined it in my head
    DIdn't want to buy ones from fleabay or ali as they didn't seem to fit the line of the 400

    I started with an old ironing board, yes, you read it right!
    the 2 reinforcement middle bars of the board fit like a glove into the rear frame
    (the high original seat bracket was already cut in the first place)

    NExt,
    I cut the board in few places along the bars in that way it follows the line of the BIke..
    Once I was ok with the design, and assured it was what I wanted and seated perfectly on the frame
    I made few small brackets in that way I riveted the bars together so the bars would stay in desired position lined firmly onto the frame..
    hope I was clear hard to explain it..

    Next step was to fiberglass it with resin and fiberglass, all across, reinforcing the whole construction and that part
    was a little bit messy, never done it before, so unfortunately no photos either as was really messed up

    in the process I payed attention and put 2 small L shaped bolts which match the 2 front holes in the frame to bolt it down...
    fixed it to the frame so they dont move and fiberglassed it as well..came out pretty bulletproof, neat...
    few layers of fiberglass+resin inbetween the board made it really unbreakable..
    trimmed it a little, sanded and the pan was ready to glue some foam on it..

    put 3 layers of hard yoga foam on it, trimmed it around,,, was scared that would not be enough,
    but if I did put another one, would have lost the line that goes from tank to rear...and you know what
    is not that bad this way either...little stiff but my but is not complaining that much

    So, now all was ready for the final touch, which is the seat cover..

    I took it to my local shop to make the one I wanted..came out nice..
    riveted it to on the back and voila'...new seat i have now

    Few modifications had to be done, as the seat was actually in the frame line, very low,,,
    had to cut off the inner plastic fender, put a new rear fender also cut it to match alltogether...
    Yesterday I came across a big bump on the road and i felt the back tyre hit the fender lightly...
    Actually, it is a little bit lower than the original one..it could look even better without it
    but then I wouldn't know where to attach the registration plates/light..
    Well, we'll see...


    Would strongly reccomend all the safety equipment, glasses, gloves and mask...
    one angle grinder died on me during the process, few drill bits broken but all in all,
    I guess some 30$ in total costs..
    im very satisfied
    FYI - I dont owe a welding machine, that would make things waaaay easier but...

    Now that's inventive. An actual legitimate use for an ironing board! Who could have imagined.

    Now if you could come up with an idea for golf clubs.................................

    You could make some interesting foot pegs with a little welding skill and a couple 5 irons(you would need a right and left handed club).
