    Avid AD's in one place
    Not sure if this is all of them but it is a good collection. If your still building or have recently purchased an Avid be sure and make sure you comply with these!

    I will share the total when it's done.  I'm doing the fuselage, doors, h-stab and elevator.  They gave me a range, which I'll keep to myself for now, depending on the amount of time required to blast.  They've done aircraft before, so I'm confident they will do a good job.
     
    Probably done next week, they told me 10 days or less.

    Larry,
    I would be interested to know what the blasting and painting cost you. You could PM me if you don't want to post it. Mine was $1000 for blasting and 2 coats of epoxy, and included tailfeathers and nose gear.
    I couldn't see all the pain of blasting on my own, and the cost and bother of painting - thought it was worth the price.  They do all of the WACO fuselages that my welder builds.
    This was a company that did our cranes when I was with the Coast Guard Indusrial, so I knew that they did good work - They charged the government a lot more!

    If you don't mind my asking, roughly how much to do that? Jim Chuk

    Well--  Here she is.  
     

     
    Dropped the Mangy Fox off at my refinisher.  Crystal Finishing.  
     
    They are going to blast with Aluminum Oxide and re-powder coat it.

  10. Guest added a post in a topic Proper Tailwheel Geometry - Castor Angle and Shimmy   

    Yeah. Tailwheel shimmy is like a balloon full of shit. Changing castor angle or tire pressure or bla or bla or bla, is like squeezing the balloon. It will go away where you squeeze it, but pop up somewhere else. Resistive damping is the ONLY way to get rid of it once and for all.
     
    It was interesting to me that while I was struggling to figure this out on my own, that others were also having the problem. An interesting approach I have seen recently with really big tailwheels is the total elimination of steering cables and springs. The huge tailwheels require so much resistive damping that they won't easily steer, so the just eliminate the steering altogether. The tailwheel is steered by differential braking action exactly the same way the RV nosewheel is steered with differential brakes.
     
    The RV nose wheel setup has large belleville washers that are compressed and tightened to produce the resistive damping to kill shimmy. Some of the big tailwheels are doing the same thing now. Very interesting. I never got a chance to experiment with this approach though.

    Kitfox issued a SB a long time ago about welding a little triangle of sheet steel at the joint of the pedestal and the torque tube - Doug Holly posted his broken cable attach tube at the pedestal,  and I believe a repair he made.

    Congratulations! The McFarlanes are nice people, they had a Taylorcraft fly-in at their strip one year and I flew the 172 in to see some of my old T-craft buddies.
     
    So what this means is that you can do the greatest thing that an airplane homebuilder can ever do... build an ultimate airplane just the way you want it, using everything you learned on your B model... while still having fun flying all the while you're building.
     
    Good deal !

    Robert,

    Sorry, I'm thinking things through while paint is drying, the fuselage is wrapped in plastic in my spray booth/garage so I can't get a pic yet.
    You are spot on though, and a Clevis pin is a great solution! I didn't think of that! I can't believe how tight that clearance to the boot cowl is though! I will post a pic in a week or two.

    Ed,
    These are the 4130 tubing style pedals and you are right, it doesn't take much to bend or break them. On my other plane I was landing and noticed I was using full right rudder and still having issues keeping it from going left. I looked at the pedal and the tubing had actually ripped open starting at a welded intersection...not good!

    Thanks guys!

  16. RDavidson added a post in a topic plastic leading edge   

    Robert,

    I think that would work, just use duct tape not masking...Ha! Just kidding I know what you meant.

    I have to give credit to Ivan Allen, another Magnum builder, he showed me the flaring trick and it worked really well. I used UPOL light weight filler for the bigger filling jobs, but for smaller filling jobs UPOL Glazing Putty in the squeeze bottle is great! It cures really fast and is waterproof.

    Good luck,
    Ron

    I hear ya. I destroyed this Avid I just got in 3 hrs today. Sad to think of the hundreds of hours and thousands of dollars these guys spent on the original build. I have all the kit info. They paid just over $19k for the kit with motor. Flew it a handful of times and sold it 23 years later for the price of about 5 tanks of fuel. Sad to think there are many more that were never saved.

    Looks good Larry. The fun part will be putting it back together for the last time. I'm looking forward to seeing that happen.

    Spent the afternoon cleaning the barn dust and mouse shit off everything today. Did a quick inventory and I am pretty pleased with what I ended up with. More corrosion on stuff that I'd like to see and I'm worried one wing may be junk due mice living the spar but won't know anything for sure until it's all opened up. Here are some pics of today's progress.

    These Flaperons look a lot closer to the wing than mine
     

     
    Has anyone ever seen an Avid Digital Tach??

  22. Dusty added a post in a topic Bush gear springs   

    The effects of cold is something I missed, we do get frost here though!
    Would rubber give a measure of damping due to internal friction?
    Rubber may eliminate metal to metal contact as the spring rate should theoretically
    Increase as the load is applied.
    The gyro guys here used to use this systym?
    Maybe in search of a better mousetrap!
