Trucks and bindings should be removed before you start trimming. The deck should be cleaned too.
Pics got orphaned during one of the website changes, but there is a
tips and advice section on the Trampa website about modifying your board. The top of the page is a pain to read because of the white text on the
grunge background, but selecting all the text (CTRL-A in most browsers), makes it easier to read.
Threads worth reading:
chopping up my trampa!! by carltb. The photo gallery referenced in the thread shows the various stages of the mods.
custom trampa!! by Rich (Trampa team rider).... very extreme board trim.
Keep in mind that the recommended weight range for a 35° 13 ply short board is 63-76 kg to yield a "firm" ride.
Of your 7kg. the deck is 2.325 kg... factor that in when you are calculating how much material you are going to remove and how much weight it will
really save you.
Your riding style should be factored in too. If you have a tendency to boost high and land hard.... something to thinking about when it comes down to
deciding how much you want to trim, as the center of the board sees the most flex.
You can trim deck material, but you can't put it back. You can always start out with a conservative profile, ride it for a while to see how you like
it and the trim some more, if you haven't made the deck too flexible.
According to Ted, you only need a minimal amount of deck where the trucks and bindings are mounted. Holes can be incorporated into the footpad areas
to reduce weight.
The
Pimped Board Thread on the KiteCrowd forum can give you some ideas about the various deck profiles people have used.
Hope that helps.
