    My web site is down temporarily, which is where the pictures live. Should be back up today or tomorrow.

    Never got any testing done where I closed off the back and made some runs and then open up the back and repeat. Every time I've taken the car out I seem to get a new personal best. My main concern was structural testing which after a year and 100 runs down the strip, I'm satisfied with. Now granted that's only at a little more than 110 mph. My big reason for building the hood was for carb clearance. I made a few tweaks to the design which forced me to make yet a third mold :Dou: But I will be popping the mold off of the plug tomorrow :TU: Has a few changes I'll post pictures of this weekend. I'll start water sanding the mold Saturday and get it ready for the next hood which will be going to the mid-west for some higher speed testing on another car :beers2: The next step will be to take my underside bracing mold and pull out a copy. Then I'll lay up another lift off hood, glass the two parts together and have a bolt on hood that will use the factory hinges and hood latch. That will be put on my car and ran around a little bit for test fit and to make sure the two parts have become one!

    Hi Craig, any updates on when a bolt on hood would be available? I plan on doing something in the next 2-3 months and I like your hood but like I said I want to get something in the next couple months. Thanks

    Until now I have not had any interest in fiberglass, but that it awsome. Sign me up for one when they are in production. This is just what the Pres is wanting all of us to do. Start a new business in our shop, hire a few people to compete with the Chinese.

    I started prep'ing the underhood bracing mold this weekend. Need to finish water sanding it with 2000 grit and then buff it. Should be laying the bracing up shortly there after. I'll post some pic's.

    It would be awesome if you'd make a bolt on cowl hood for the 64-65's.

    Well, it's big step, I finished up the first fiberglass underhood bracing. It still needs some trimming once I see exactly were it'll bond to the hood. The pictures show the bracing and the bracing just set in the mold to check initial fit. You can get an idea of how much extra height there is over a stock hood. The bracing on the stock hood goes all the way across the hood and is flush with the underside even in the center. This weekend I'll bond the aluminum backup in the bracing where the hinges attach and lay up a hood in the mold, then do final trim and fit on the bracing. After that, I'll bond the two sections together. I also need to see how I'll integrate the air box. Seems like it's taken forever, but I'm just about there on the bolt on hood.

    Well, this past weekend I laid up the new hood and an air box. This week, I popped the air box out of the mold and sat that and the bracing on the hood thats still sitting in the mold. This weekend, Ill trim the air box so it fits flush, glass it to the hood. Then Ill trim the bracing, bond on the aluminum to the back of the bracing. This is what the hinges will bolt to and bond on some aluminum reinforcement where the hood latch meets the bracing. Once thats all complete, I can bond the bracing to the hood and let it sit for a few days. Next, pop the whole deal out of the mold and see how the first bolt on hood looks. I need to find those hinges, theyre around somewhere in the garage! I still have to trim the back side at the cowl opening, but I wanted to wait until I get it on the car to decide how much of the bracing I need to trim back.
