Siva Carbon Skateboard Deck Brackets

How Do All ;-)

Here is a preview of my new, Siva (Shiva) Carbon skateboard deck brackets.



I have been working on these for longer than I care to remember now, and with trips away and other stuff going on it has been a bit of a start stop job.





I made these to replace my hand made alloy brackets which I have been riding on for a few years now and loving very much; and as the angles have been dialed in to suit my style and end use. I decided the next step was a full Carbon set.
I have put them on my old deck for the moment to get a proper comparison between these and the Alloy brackets, but there is also a new Siva deck in the making to compliment the brackets. 




The brackets are solidly made using many layers of Carbon fiber and some triaxial glass fiber, this does not save a great deal of weight over the original brackets, but stiffness and longevity were my main concerns here, there is the possibility of a lighter version in the future.  



The front bracket is +21.5 degrees and the rear is -7 degrees, for me and my set up these are the perfect angles. not too dead in the rear and just the right amount of wiggle up front for squirreling around town.

Below are the brackets mounted on my old Wood, Glass and Carbon Om deck  the new deck will be a little stiffer and much lighter.



I have also made some new bumpers or bash guards for the front and rear made from Black HDPE, which replace the Grey Nylatron ones, I made them a little wider and squarer to give more protection to the ends of the brackets. these are pictured below.


Also featuring and in test on this deck is the new "Kick 2 Switch" footstop modification.


I have only had a short time to test the new brackets but initial tests made me drool a little, so all is good.

Thanks for looking.

Kick 2 Switch (Footstop Mods)


How Do All ;-)

I have been practicing pumping switch since sometime last year, and have become pretty proficient at it now and try to pump switch at least 50% of the time.
The one thing that bugged me was having to compromise my foot position due to the footstop being the wrong way round.

What I have done to get around this is to centrally mount the footstop and also make the foot stop able to swivel with a gentle kick or push of the foot.




Before I carry on I should note that what I have done may not be the best way of doing things and may also not be as good an option as having a multi angle footstop like Tim’s (psd) Twin or Wings design, but for me it works fine and gives a large constant surface area; at the cost of a new hole drilled through the deck mind ;-)

I first drilled, tapped and countersunk the bottom of the deck centrally between the two front most truck mounting holes (this position works really well for me) I then glued and screwed an M6 countersunk screw into this hole.
I also countersunk the two front most truck mounting holes so I could use countersunk screws making a little more clearance than with the pan head screws meaning the footstop could be mounted lower to the deck and not having the truck mounting screws in the way.
I added 2 thin SS large diameter washers on the M6 screw, then the footstop now drilled out to 6.1mm, followed by a drilled out large diameter M5 washer, a hard nylon washer and a Nylock nut to finish.

The footstop is tightened just enough so that it will swivel when pushed with the foot but not so loose or tight that it either spins of takes too much effort to move.


The footstop is now able to swivel to any position for ultimate comfort in any stance, making pumping switch on the same deck possible without compromising the foot position or pumping efficiency, and as the foot stop is mounted centrally your foot position will be symmetrical whichever way you decide to ride.

I have done this to two decks now, using both a PSD Barrier footstop and also my own wood version of the same.


I know that some Slalom boarders have a footstop that swivels either by design or just because it happens to, so I am not claiming to be the first to do this, but I think the way I have done it and the reasons that I did it make it worthwhile sharing.
