    Wow Jim that is fantastic your sheer drive for these projects.
    will you be going to Sun n Fun this year?  I’m thinking about flying down.  It has been a long time since I was there last and never in my own plane.

    912 gearbox
    The 912 ULS gearbox should be sent in for rebuild before 1000 hrs.  The dogs wear out and must be replaced.  Failure to do so results in the gears failing also.  You will know that you have waited to long when you throttle back on final approach and you experience vibration.  Hopefully the newest engine with the oil spray tube will take care of this issue of dog wear.

    Have you seen this site? You might give them a call and see what they have that might work for you.

    So my spring is about 1 5/8 wide with a single hole at each end and yes it is the long leaf of a three leaf spring. Not to sure if this is going to be any help.  Mine came from Backcountry Super Cubs. If I remember right he had the spring made here locally.  I looked for the rest of the spring (other two leaves) but did not find it.  As far as the single leaf not being enough for your plane I would think that would depend on what the weight on your tail wheel is.  If I remember right the MKIV mine is about 65 lbs.  I will check with Bruce BCSC and see if I can find out more about his springs but you may be able to get a local spring builder to make exactly what you want.

    I’m using the long leaf of a Super Cub spring on my MKIV not sure what the measurements are but I can check it out if you are interested.  The original one was not true spring steel and I had to arch it several time before I replaced it.  Let me know if I can help.

    Not aircraft related, work bench
    To quiet here so here goes.  I’ve always planned to make a nice work bench so after deciding to start building some guitars no time like the present.  This is a knockdown number that can be assembled in about one minute and transported easily.  There are no screws or fastener, but just joints, mortise and tenon, dowels and some dovetails.
    on a side note if you use a rasp check out the Shinto rasp, totally awesome.

    I believe that it was radiated energy from the open high tension ignition lead in this case.  I believe your solution would work but now the cause has been resolved.  Thanks I will keep that solution in my memory banks for future reference.

    ok I won’t drag this out any longer.  You are on the right track.  I had that issue with the fan motor on my heater. Installed a diode across the leads to solve that spike or back emf.  These problems we all caused by a bad resistor spark plug cap that Rotax uses, open circuit.  Removed the caps from each of the spark plug wires and tested them with the ohm meter.
    Anybody else have some strange issues that they solved, let’s hear them.

    Tech Puzzles
    Ok. So let’s see if there is any interest in this idea.  I’ll start this off.
    so I’ve had some issues that were driving me whacky.  Avid with a Rotax 912ULS.  #1 I have installed SDS fuel injection.  I would get an occasional map sensor fault.  Changed out the MAP sensor and checked the wiring no joy, didn’t change performance just cleared it and keep on flying. This started over a year ago.
    #2 this spring my tach started reading high above 5000 RPM.  Sometimes floating as high as 13000 or so, Indicated with my MGL Blaze engine monitor.
    #3 Radio issue MGL V6 radio.  Radio started tripping out a month ago, lights on but nobody home.  I could reset it by turning the power off and back on but this radio has no on/off switch so in the air it entailed shutting down the the engine due to the EFI setup.  I did not like doing that so I added a comm power switch.  Noticed a bit of background static some months back when receiving.
    So there are the puzzle  pieces anybody interested in solving these puzzles?  I will say that I have solved these puzzles and will offer up the solutions in a few days but let’s hear what you think.

    As you found out using two sets of Mc1 does not work for dual brakes.

    Interesting that’s the only 800 number I saw, they did have some other numbers listed but maybe those aren’t working either.

    Apparently they sold out to Advanced Powerplant Solutions 800-532-3462.
