Top image is one of the car from 1974. I highlighted the piece I am/have fabricated. Glass work done, 3 layers of 8.8 oz modified twill with epoxy resin (black pigment). I sprayed some PVA over the foam - waste of time. It released from the foam, I should have either covered it with tape or skim coated it with polyester resin (to seal the foam cells). Tyring to keep this simple and fast since I am not trying to make these ' Mona Lisa's ' or going into mass production. First trim - cloth cut away and roughly trimmed to dimension. Sample fit up - about 2-3" will be trimmed off the top of it and will run parallel to the contour in the fender. The piece is very light weight, I will probably add another layer of 8.8 oz glass to stiffen it just a bit. Final step would be to give it a light sand and then finish with some body filler and then ready for paint. These were attached with just a couple of pop-rivets.

So from the ' loaf ' in the last post I SLOWLY start to carve the excess off. You can add foam if you make a mistake, but it is a PIA. As always, better go slowly - measure twice, cut once. I use a variety of tools to cut the foam - my wife's favorite bread knife, small serrated steak knife, hacksaw blade, sawzall blade(s), 80 grid sand paper, etc., The shape came out how I wanted it and what is really nice about this foam is that you can create very sharp edges - if desired. Next post, fiber glassing.

I don't like to post more than 5-6 images in a single post so this will be probably 3 parts or so. Now that I have pulled the new parts from the molds for the rear fenders, I decided that now was a good time to make the rear skirt (I am calling a 'skirt' as I really don't know the correct technical term for the piece. A true skirt would run the whole length of the rocker I believe. This part attaches in line with the door jamb to front side of the inside wheel arch). It has been a long time since I had used expanding foam and had to dig up some old brain cells to remember some of the processes. Having the fender off the car was definitely the way to go. That being said it is still a messy process. The bottom side of the fender gets masking tape (2 layers +) then all of the inside surfaces of the cardboard. I use lightweight cardboard (again lined with masking tape - the foam sticks to the tape, but not like it would stick to the cardboard) from my favorite cereal boxes to make the mold. This is 2 lb - 2 part expanding foam that expands about 30x - I mixed up about 8 oz. for this application. After about 30 minutes, I strip of the card board mold and you are left with a solid mass of foam. Next post shaping.....

Very much in need of a pair (two) of these dry break fuel couplings. The AlpinA Gruppe 2 car had a fabricated aluminum tank that utilized this type of fuel coupling. The tank is long gone, they are definitely a critical component in the fabrication of this tank. I was told at one point these were "Relumit" female dry break couplings (not sure if that is accurate though). If you have one (or two of these) or know where I can get them please drop me an email - thank you.

Last weekend I went to the Monterey car event for the first time (pretty sad really I only live an hour and a half away and had never gone before). What an incredible experience. Started off at the Legends of the Autobahn event at the Nicklaus Golf Club. Car corral's and judged event for BmW, Audi and Mercedes (sorry, NO Porsche's). My borther-in-law Jeff Jarvie snapped these photo's (thanks Jeff). I was so entranced with the visual, I didn't take a single picture. Top you have the Motorsport Z4 M's on display, pristine engine bay of Daniel Cooper's "Baikal" '72 2oo2 tii, BmW Motorcycle of some sort (sorry, zero expertise on two wheel BmW's) and a lovely "Ceylon" gold BAT CSL (one of a heard of CSL's). After that we headed down to the track and walked through most of the paddocks. Back end of a Porsche 935 Turbo. Last two of a "parade" of Shelby Cobra's. Notice the lady plugging her ears? I wasn't too far away doing the same thing - these cars are absolute BEASTS, multiply it by 4 with unrestricted exhausts = really loud. Thanks to Jeff for the photo's.

It is official, BMW will be the featured marque in 2016, 2o years since they were last the featured marque. It is going to be an incredible time.
