    concrete cleaner

    Muratic won't do much for paint, it'll make a conspicuous light spot where it etches the concrete though. I'd try paint stripper first. Gasoline and a brush works best for breaking down oil that has soaked in to the concrete.

    Ethanol free gas?

    I doubt 91 octane E10 is higher in octane than normal 91. It's probably all mixed anyway until they get the required rating. After the motor blows up would be the perfect time to install a steam crossover tube that links the 2 heads at the back and dumps into the radiator/lake/whatever a boat...

    110v Welder

    Keep in mind good tools are an investment, you'll always be able to resell a 220v millermatic. Toy welders don't have much of a resell because nobody really 'wants' one they just settle for them.

    Chevy Volt

    uh no it's not... ? They're all expensive, as would be expected for the first generation of practical alternative energy cars. Electric cars will be awesome when new technology allows them to enter the performance market.

    OBD II not syncing

    You're saying the scanner won't even know it's hooked to a car if your battery has been disconnected within 150 miles? :laughing: it'll just report not ready.

    Wiring???

    I build performance automotive wiring harnesses at work and I'm way into electronics design, always looking for sidework. PM me some pics and/or describe what all needs to be done if you're interested.

    CB Antenna

    It's not the antenna, it's the mandatory tuning and mounting location/method. http://www.firestik.com/Tech_Docs.htm I was holding a clear conversation with a guy 30 miles away line of sight after I tuned mine.

    Electronics Stuff Locally

    LEDs are current controlled devices and they have a very non-linear voltage vs current graph, so even a small increase in voltage could double the current through the diode. Since automotive voltages could be from 10-16v a regulator would be good practice and will hold it at 1000mA all the time...

    Electronics Stuff Locally

    Sounds like you're driving 1amp worth of LED(s). You could use a LM317 voltage regulator configured as a current regulator. This will give you the added benefit of actual current regulation and still only requires 1 (smaller wattage) resistor. 12v 3w led drivers are very cheap on ebay BTW.

    proportioning vavle adjustment

    Just in case I'm psychic though: http://www.wilwood.com/PDF/DataSheets/ds488.pdf "Rotating the adjuster knob clockwise until it is all the way in will provide full pressure delivery to the calipers. Rotating the knob counterclockwise will incrementally reduce line pressure up to 57% when the...

    proportioning vavle adjustment

    Are you asking which way you should turn your valve for more (or less) pressure? Knowing which valve it is would be helpful for starters :)

    coupon for grinder

    I though the normal price on those was $15 lol I've used the bajeebus out of my dewalt grinder that I picked up on clearance for $35 at Sears. Normally I don't care for dewalt tools, but this grinder has been excellent. I've never used tools to change the wheels out either, just hold the lock...
