    Not only Kinner. Technical bulletins from American Cirrus and Continental ( for the A-40 ) suggest the same thing.

    The EAA is not a regulatory body. There is no such thing as a journeyman aircraft welder in the USA, that title does not exist. When I was looking up the requirements to me an Aircraft Maintenance...

    Very Cool! Now.....someone needs to champion getting it back together!
  4. One thing I don't understand about your position...

    One thing I don't understand about your position Mr. NixRox, is why you are seemingly so anti-experimental, when your dad flies (or flew) an experimental C172 with a supercharged ( to 430 HP) GM LS...

    In the experimental world, I worry more about guys using car engines, but that is the spirit of the category right?
  6. Some of us do not feel the need to shove...

    Some of us do not feel the need to shove credentials around,and at least in my neck of the woods it is usually considered in poor taste and is seemingly reserved for academic types. Back purge is an...

    Question: Why do you assume some of us are NOT professionally trained weldors or welding engineers with years of experience? Also, here in the USA there really is no generic journeyman welding card,...

    Miller is not an authority on aerospace weldments on 4130, they are a company that makes welding equipment ( To be fair NONE of the welding machine manufacturers should be considered design experts...

    See above for my comments.

    Just for clarification, you were an inspector, not a weldor correct? I see in your list of tools that you have mig welders and a stick welder, so I am guessing you...

    Well this certainly got weird fast. The thing is I get where nixrox is coming from, as I work in NDT and materials as well, however there has to be a dose of reality there as I also work in...
  11. Wow.......

    Wow.......

    I appreciate your input from a safety perspective, but I do have to disagree with you on a couple points. First off on engine mount design, considering the time period most GA aircraft were designed...

    Ive had good luck with mid states aluminum making custom extrusions. The cost is not that high and you can usually sell what you dont need and recoup quite a bit.

    My big concern would be, where did the porcelain go and what damage did it do on the way out. I've seen them get stuck between valve faces and seats, causing damage that would later lead to a valve...
  16. Oh I know what you mean! One of the disadvantages...

    Oh I know what you mean! One of the disadvantages of tig on 4130 is that every stop/start usually has some areas of the HAZ that are really hard, yet when welding a cluster man its difficult to keep...
  17. Keyhole welding is you are using enough heat to...

    Keyhole welding is you are using enough heat to cause the edges of the material to melt, pull back, and recombine on the back side of the weld pool. If you were to stop welding it would would like a...
  18. It was never for expansion, but actually it does...

    It was never for expansion, but actually it does help with contraction and "locked up" stresses. Although many times to the confusion of others, authors of welding texts will interchange the two. So...
  19. Well, unfortunately it is all copyrighted...

    Well, unfortunately it is all copyrighted otherwise I would scan and post the documents here. The gap does indeed help quite a lot in forming 100% penetration weldments, although it does make welding...
  20. Part of the purpose of the gap on butt type welds...

    Part of the purpose of the gap on butt type welds is to provide some gas coverage into the joint itself. It also allows the arc to reach between the two parts, something it cannot do when fitted up...
  21. Oh for sure, that is standard practice in...

    Oh for sure, that is standard practice in industry. Unfortunately there are some jokers that tell you to fit things up tight and use tiny welds, even though that goes against AWS specs , 43.13, the...
  22. The thickness is not helping for sure, however...

    The thickness is not helping for sure, however with proper procedure and practice it could be done. The biggest error I see in hobbyist tig welding is lack of penetration. There is so much fear of...
  23. Ok, I was trying to figure out a positive way to...

    Ok, I was trying to figure out a positive way to say this, but instead I am just going to be blunt. That welding job scares me. The penetration is non-existent, the welds are not complete, and the...

    Thats just advertising bullplop. None of the ford modular or current engines are designed for WOT operation, same goes for the LS series. Unfortunately some of the issues cant be fixed swapping...
