A little progress on the Build-Off Pete. Not much, but haven't had much time to tinker around.
I'd say the truck is on the home stretch here; mirror brackets are on, rear mudflaps and tail lights. The exhaust tips I have ready as well, just waiting before I have put some work behind me that could snap them off again. The hood is done and waiting as well, I just need to figure out the hinges since the resin aftermarket part isn't prepared for the kit's hinges. Also I fear that I might have mounted the cab a little too high (talking about halves of millimeters) so I need to set the hood just right. With all the effort on the C15, I try to make the hood functional.


After that it's off to the upfitter, for the custom bumper and rear fenders. Mirrors will be the last items on, last decals will be the license plates.

Disclaimer.  I am not professional and there is a possibility that I have no clue what I am doing.  I hope that I have put enough info together to give you a good I idea of the steps that I use to create single hump fenders.  If clarification is need, please let me know and I add info/edit as required.  Sorry for not taking a few more/better images.  Hope this helps! 

1.  Begin by cutting a 1 15/16" round disk from a sheet of .040 sheet styrene.  I used a bow compass with metal points on both sided to get the job done.  If you use this method be sure to make the center hole the same size as the compass point; if it is larger you will not get a symmetrical disk.

2.  Mount the disk on a Dremel cutting wheel attachment. (The image below shows two mounted but one is fine.)
 
3.  Begin to round the outer edge of the disk using a rasp of other coarse file, sanding stick etc.

4.  Fine tune the chamfer of the outer edge of the fender with a sanding block.  I used 220 grit sanding paper.

5.  Finished disk on the right.

6. Before performing this step make a mark that divides the disk into two equal halves.  Then cut the center out of the disk leaving a 5/8" circle and then cut the circle in two.  You will then have two "C" shaped pieces as seen in step 7.
7.  Glue a .060 x.040 styrene strip (SS1) around the outer edge of the "C".  One of the .040 sides should be glued to the "C" and the strip should extend beyond the end of the "C".

8.  Cut a hole with the same diameter as inner hole of the upper fender wall (UFW) above from a sheet od styrene and layout and cut the lower fender wall (LFW) as seen in the image below and the image in the next step.  (Sorry for not taking better pics of this part)

 9.  Glue the LFW to the UFW and SS1, and cut the ends off SS1 off at the lower edge of the LFW. 

10.  Cut the lower portion of the LFW to achieve the desired fender height.

11.  Glue a .030 x .250 strip (SS2) inside of SS1.

12.  Make another side just like the one above.

13.  Cut two strips of .020 styrene to the desired fender width (don't forget to account for the width od the sides) and long enough to wrap around the outside of the fender.

14.  Beginning at one end, glue the first SS3 to SS2, wrapping it around the outer edge of the fender as you go. Be sure to keep the seam between SS3 and SS1 on each side as tight as possible. Cut the ends even with the lower ends of the fender side walls.


15.  Wrap the second SS3 over the first SS3.  Again, keep the seam between SS3 and SS1 on each side as tight as possible and cut the ends even with the lower ends of the fender side walls.

Construction complete!

Fill and Prime

Paint

Repeat x4.
If all this seems like too much work, you can purchase a resin set in the Parts Store.

The Build-Off Peterbilt is getting close to completion! I have the hood functional, the mirrors are on and I made a big bumper from styrene. All that's left is the fenders over the rear wheels; I'm still not sure about the definite style and way of attaching them, but I have some time left to figure that out. License plate decals and IFTA decals are last. The stack tips are in place as well, but I'm not really sure If that was smart. I might have to work on the underside of the truck a little for that. Oh well...
