    Aluminum seat hinges

    Here is a full set of seat hinges I'm working on. I've added a 3rd hole on the upper to give finer adjustments. The lazer cut pieces come with edges that are a little rough. I talked to a couple people and they say you get about the same results with water jeting. Has anyone heard something different? The only power tools I have are a drill and a dremel tool. I had to borrow a drill press to countersink the holes. The steel ones currently on my drivers seat don't have countersunk holes. I have 5 or 6 hours of hand labor so far (mostly smoothing out the edges) and I think I'll have about 10 to15 hours in them when I'm done. I'm going to have the head shaved on the bolts to give them a flatter look.
    I can have these cut in either Aluminum or Steel. Someone could drill a bunch of holes to give them a racer look? The steel ones could be chromed to give them a more orginal look. This has been a fun project. It would be interesting to see how many ways people would finish these off. These should fit cars to 1973. The center hole on the upper would need to be left out on the later cars. They should fit the later 356's also.

    My car is with Dean in California. He and Richard Clewett are spending some time with the car. I wanted Dean who built the engine to get some seat time in the car. He has had a lot of experence with the 356/POLO setup but none with the 912/POLO. I figured it would help him and me if he spent time with the car. He just built a 66mm short stroke 2.5 for a 911 and drove it. He felt the 2.4 POLO pulled as hard if not a little harder than the 2.5. As he and I have a bias for this engine, lets just say they are very close.

    If I can I'll bring the car by European Collectables on 9/25 for a couple hours on my way up to Cambria,Ca.

    I spoke to Dean Polopolus and Richard Clewett yesterday. They spent the afternoon together playing with and tuning tne 912P car. They seemed to be very pleased with the results. I asked them what the car might need. They said bigger brakes!
    I'm looking forward to getting behind the wheel again at the end of September.

    Round and flat hardware. They weigh 2lbs each or 4lbs per seat in aluminum with all hardware. My factory hinges with crossbar weigh 7 1/2lbs.

    I was told you add about 15% for #'s at the crank.
    I chart was for 5900 feet. The other is their sea level adjusted #'s.
    Richard Clewett was there tuning the car.

    I have the beginnings of a website up. Some parts are not functional yet, but it's a start.
