Good looking project irk_miller.
I built an SL 350 for vintage racing and the stock fender on it was aluminum and looked good enough to me that I left it on even for racing, and I had thought that one day I may make a street bike out of it.
I always thought that fender would look good on a vintage bike
I think the frame and fenders I used were a 1973 model, not sure if other years used the alloy fenders
It was good to see that CL, because now I think I have a better shape with this fender (though it still may be a little long). Now it's step one towards the seat. I didn’t take pics of the foam base, but basically I cut and carved insulation foam, taped it up with masking tape, coated it in mold release, then laid no blush epoxy and fiberglass mat. I thicken the epoxy with System 3 fused silica, so I can lay it thick and so it holds on vertical surfaces. When the epoxy cures, I’ll trim the edges of the pan to the horizontal frame tubes, then sculpt a hard foam master shape for the cushion, make a mold, then cast the seat cushion. More on that when the foam and stuff arrives from Charlotte.
Cured overnight, rough cut the sides (not the ends) with shears, removed the foam, and now I’m adding a few more layers of glass...
nice work i bet the epoxy doesnt smell nearly as bad as polyester resin
i am pretty sure i have a spare alloy rear fender from my sl stock
i check tomorrow over at the storage
the rear fender on there now def has to come forward it just looks wrong
the rear tip should not be past very much at all ,what can we call it ?
how about the spinline the rear tire vertline
but mainly to look right it needs to be even gap around the tire when suspension is full bump
if you always use that as a guideline they will look RIGHT
BY THE WAY THAT REAR FENDER SECTION YOU HAVE ON THERE LOOKS CLOSE TO CZ MX
I think i got it fixed, for the most part. I should've known it wasn't quite right, when the top profiles of the two halves didn't match at all. I pulled the shock, dropped the rear end onto the wheel and lined everything up. The rear section was pretty far off, but much of that had to do with the angle of the hoop. It was way too steep. I ended up dropping the hoop a good 2 inches or so.
On a side note: I got the headlight installed. It's huge, since on the original build I went with an aftermarket that was a close to stock as I could find. TBD if it's the right look for this version of the bike. I honestly prefer a bigger light. Seems a lot of builds nowadays want to go with the smallest lights that are mounted way back in the forks, and I'm not sure I like that look.
not feelin it,too long,to dumbo the elephant...
needs to be like the vettr i have
no tools and its short fr t bk
nice big clocks and the bucket high enough to block bottom view of clock cans
finish in rakishly garrish flyshadescreen,bubble, see

Despite the lack of love for my 1935 Chevy truck headlight (I actually like it), it remains. I do want to try that more shallow Vetter. I tried a smaller than the Vetter 6v light with a similar shape that didn't look right at all once the gauges were loaded.
The seat pan is complete. I end up mounting all of my seats with a GSXR pillion seat latch. The front of the pan slides into the frame's backbone via machined delrin cup.
