Well, missus out and I found some foam board while clearing the garage out after replacing my front discs...

Started to make a pattern for some winglets/side panels that I am tentatively planning on making from carbon fiber at some point...

Just trying to get a basic shape really but here is the fruits of an hours labour while ducking in the house to check on the little 'un.

I am liking the shape so far, I wasn't after totally flat wings, not sure if I will extend it down the radiator as one piece or have it two piece. I was going to use expanded polystyrene but its just too messy to sand down, it gets everywhere and er'indoors wouldn't be too happy so foam board and a razor/hot glue gun is all I can really use at the mo. Final shaping will be with body filler and sanding .... outside (apparently).

like it! how are you going to attach them?

Will they not cause any air noise, they're not exactly aerodynamic?

Probably use the fairing bolt point at the rear and maybe use the indicator hole or something.

Not aerodynamic?

Aerodynamic- are you going to put a skin/surface over the ribs, i.e. are they purely structural or are they finished concept.
Either way, it's looking good

Ah is see now. This is simply to create a plug I will make a fiberglass mold from. I will be filling in the sections around the ribs and this will be a smooth shape.

I'm more than likely totally off point, but they look like they're gonna get a wind rush over them.

Better get yourself a parachute

There was a rumour the in laws were taking the little un for a few hours today but that plan changed. I only had time to make some filler blocks for the ribs and give it a rough sand to get the basic shape for a quick look see...

polystyrene blocks cut and set in place.

After a quick sand.

I had wanted to extend the standard fairing a bit further than this is doing (along the top of the frame/tank) but it hit my knees. This currently will clear knees with the armour I wear quite comfortably...

Probably be the end of the week until I can do any more

I wasn't entirely happy with the original shape and also thought it was a little small.

After faffing about with the white polystyrene I got some proper blue foam which is miles better to shape and much easier to clean up. the white stuff got everywhere when sanding etc and static sticks it to you, carpet, shoes, living room carpet... 'er indoors wasn't best pleased!

So yeah, blue stuff, shapes really nice and doesn't make much of a mess. A glowing endorsement - It won't take body filler though so I will need to coat it with something before that stage, probably some poster paint or PVA.

I have the leading edge of the "wing" following the same line as the engine head just to tie it in and have some continuity with the existing bike lines etc.

There won't be any gaps, this is just the basic shape, I will add body filler and blend it smoothly into the original fairing then add a section that will run behind it then extend up to mount points. This will then be used to make a mould... Thats the plan anyway, I have some carbon fiber big enough to do these but will do the first ones in fiber glass to test them out.

There will be a shaped underside too by the way, I am just getting the top done first

Why not

It'll keep the front end down a la Rossi and Lorenzo

NorthWestern · « **Reply #17 on:** 13 December 2015, 12:15:59 pm »

I guess the point is that I had a paint scheme that would only work with a slightly deeper front fairing but I don't particularly like any commercially available side pods. Plus I have grown to like the little winglets so decided to make some

Like it, how you going to mount them, me thinks you'll need some substantial mounting points to cope with the wind pressure forcing down on them

NorthWestern · « **Reply #20 on:** 13 December 2015, 03:00:21 pm »

As far as downforce I don't think they will be particularly efficient, it is mainly cosmetic however we shall see

The finished part will extend behind the upper fairing and mount at the rear fairing bracket and the indicator hole, I will probably incorporate a mount point on the front upper radiator shroud mount point too just to keep in in place width wise.

The basic shape is pretty much where I want it before I put body filler on and finalise the shape/curves ready to make a mould off it. I am not 100% set on the lower section angle or the front upper radius at the mo. It also lookss a bit blunt on the leading edge but I am wondering about laying the carbon in such a tight angle, it should be fine, I guess I can refine the shape in future versions if I am not happy with it.

Side on - the front, where it meets the upper fairing will be flush, it looks a bit stepped forward here but its jsut because I have simply shoved it in place. The foam is a bit cut and shut as I used some offsets that were too small to use in a single piece, when I do the left I will use single blocks as its easier to shape without glue inbetween...

Anywho, just opened my filler tin and there isn't enough to cover this really so that's it for now...
