    Great instructions and pictures MM. I ran down the basement, during the break, to be sure I had all that stuff, just gathering dust on the shelves. Can't wait to get started.

    Oh wait. I have a justa. I don't need one. :lol::lol::lol:

    I had a little time today and did a quick layout of the pressure pot lid. I'll probably fire up the mill this weekend and cut the piece out.

    It's not the same on a car engine, is it?

    I was told that the system for walnut shell blasting the gas turbines in small warships decades ago was to remove the intake grilles (that stop birds, etc going in), run the turbine at idle and then a guy threw the crushed shells from a bin on the side deck into the intake using a shovel.

    Seems easier..... :idea:

    Thanks Jeff (05r50)

    Yesterday at the MOM donut munch, Jeff handed over the USB endoscope I had asked him to pick up for me since he was getting one as well. I wanted a low cost method to do a visual inspection of the carbon buildup on the intake valves. This is a cheap Chinese USB flexible shaft camera that has 4 small surface mount white led's. Brand name "SuperEyes from fleabay for around $40.00.
    No expensive optics here, but what's needed is the ability to flex around corners and it must have an integrated light source.
    It's somewhat tricky to hold the probe steady, focus and snap the picture all the while balancing the laptop on the engine..... But I think it will serve the purpose....
    Here is the unit in all it's coiled glory...

    [​IMG]

    Here are some sample pics taken inside the valve cover (unfortunately it's very easy to bump up on oily surfaces which then messes with the clarity, which shouldn't be as much of an issue in the intake)....

    This is an awesome project I will follow but am glad I will never need.
    Keep up the great project and pictures MM.

    Had a little time this morning for some work on my carbon blaster....

    Standing upright now....:D

    [​IMG]

    Want to put a handle on the lid and then it's off to the powder coater....

    I pressure tested it last week @150 psi (I hid behind the 90 ton break press, just in case it went BANG). Not even a leak. The "O" ring design seals tighter with increased pressure....:D

    At work, we inject walnut shells into the compressor side of the turbochargers with a pressure pot and ship's air pressure daily, about two pounds of walnut shells in around 30 seconds. We do this at full load.

    Monthly, we water wash the exhaust side of the turbos at reduced load until the water comes out of the turbo drains clear.

    These turbochargers are on a 20,000 hp two stroke diesel and they are the size of a MINI. The the rotors turn at 7,000 rpm at full load.

    Today's Update.....

    Welded up part of the tank today...

    [​IMG]

    Assembled the lid with the "O" ring seal....
    Price on the Viton Fluoroelastomer "O" ring.... $4.62 USD

    [​IMG]

    Everything fits well....

    [​IMG]

    [​IMG]

    I still need to add some bungs to the lid and some on the side of the tank. These will hold the safety "Blow-off" valve, pressure gauge and fitting attachments. The bottom also needs to be added as well...
