Level plus

Clay would have been far easier to work with

Luckily I can skip the carbon fibre sheets as the fibreglass is so thick, probably added another 10kg to the overall weight of the bike

Yep but who has the back end of a car laying around that could double as a flower pot?

I couldn’t purchase the right kind of foam to shape, even at Clarke rubber which is the go to for foam products here

That’s why I ended up using thin cardboard which was less than ideal

But I wouldn’t have had nearly as much fun doing it that way, plus I was worried with the economy being the way it is if I didn’t keep purchasing resin and fibreglass that the companies may go under without my support

Good answer. I made a plug for my seat but said heck with the fumes and dust to do the mold. Fiberglass is nasty and easy all in one package.
On a serious note, the bike is coming out nice. My dad has an F model and if the engine wasn't trash, I'd go snatch it up from him.

You’re dam right about nasty, I wear coveralls,mask and rubber gloves the neighbours probably think I’m some sore of weirdo... even more than they previously did.

The dust is everywhere I just did a big clean up vac first then hit it all with compressed air then do it all over again I think once I’m finished the dust will take a will to get rid of.

So I taped up the sides of the seat and poured resin on the top of the pan to level it out again

Then I filled in the sides to give it a little more of an edge and less of a rounded look

I graves the gaffa tape and masked up the top and sides of the seat to make a seat pan for the upholstery

Then I got my fibreglass cloth cut it to shape

Then I hit it with the resin

This gave me the base to work with

I put it onto the bench and put another two layers of cloth on and waited for it to cure before I would trim it to shape

It came up pretty good, tomorrow I’ll attempt to put some foam on and cut it to shape.

I still haven’t cut the end of the fairings yet, I just can’t seem to the angle looking right to my eye, best to do other stuff

I’m going to need to work out a way to attach the upholstery to the seat I’m leaning towards Velcro

You're getting better at this lol. By the time the seat is done you'll have gotten past the learning curve, just to forget half of what you learn by the next time you do it :eek: ;D. Nice work

So I cut some of my scavenged underlay to size and stuck it down

Unfortunately after “decontaminating the garage and trying to purge out all the fibreglass dust. This is as far as I’ve got

If I’m lucky the wifey may get a chance to sew up the leather to upholster the seat, but I dare say my young fella will see to it she has no time.

I still didn’t get the end of that front fairing cut I just wasn’t feeling so I’ll have to let it sit for the next six months

When I come home I’ll have to prep it for paint. I’ll also need to get some tracing paper because I need to trace the blue decal off the tank for my brother to replicate... I’ve searched and have been unable to find them like that ... if anyone here knows where I can get them in that blue I would be most thankful

Anyway time to pack the bags... still have to wake up early and wash the cars that are covered in fibreglass dust before I can fly out.

So I just saw this on another build here where the guy made the switches up himself,

I’ll have to purchase some micro switches then work out how many switches I need.

Left would be;
High beam
Low beam
Indicator left
Indicator right

Right
Start
Stop
Horn

I think that’s it

Just FYI, when I got the tank decals from reproduction decals for my bike, they did do custom colors. It was a little more in price but they will do it, just have to contact seller/manufacturer and verify that they will work with you.

So being stuck away from the garage for weeks at a time means the eBay account cops a thrashing

So I ordered a second hand tank rubber but when it arrived there was a huge hole in it, I contacted the seller and they offered a replacement

Next thing I went on the hunt for was these micro switches, they were about $17 a pop. I’m hoping this will turn out as well as the ones in the photo

Although I doubt we will get it done this Xmas break still have to fab bracket to mount the damper, gear linkage, front fairing and then the switch mounts lol

Here I was thinking id be riding Frankenhonda this summer
