DIY Seat Cowl (with pics)
Hey people, after sitting around bored this morning nursing a small self inflicted hangover i decided i would get to work creating a diy seat cowl on my spare rear fairing for my NC29.
This method is certainly not tried and tested and would not recommend people follow it. I am a complete NOVICE when it comes to bodywork.
I am not posting looking for gratitude just proud of what i managed to complete so far...

Spare rear fairing with seat attached.
First of all i had to remove the rear seat and strip it of it covering. All i done was simply pick the staples from the underneath.

Then i completely covered the foam seat cushion with masking tape and formed a 'bulge' in the centre, taking care to ensure it was perfectly central. At this point there was aload of creases in the tape, if i were to do this again i would of take care to get the all smooth.

Next i covered the masking tape covered seat foam with glass fibre sheeting and soaked with resin. This was quite time consuming and very very messy!

Once dried (approx 2 hours in my case) i had to gently prise the fibreglass mould from the foam seat.

Once removed i then filled the inside with plenty more of fibregass sheeting and soaked once again with resin.

Once dried the edges needed trimming slightly, i just used a dremmel but im sure any sort of cutting instrument would of worked.

Next i them laid the mould onto the rear fairing and fibreglassed in place from the inside. At this point i was slightly concerned with the way it fit against the fairing but that was ok once filled.

Now it was starting to take shape the next thing was to cover with filler ready to be shaped and sanded.

At this point now i am going to leave it overnight before sanding starts. I will update post in due course.
PS. Fibreglass and filler fumes work a treat for a hangover

Re: DIY Seat Cowl (with pics)
so all in all, how much do you reckon it would cost to produce something like this?

Conventional wisdom says to know your limits. To know your limits you need to find them first. Finding your limits generally involves getting in over your head and hoping you live long enough to benefit from the experience. That's the fun part.
