    Just on the off chance anyone has some hoarded away, I'm looking for 32 AN150-16S turnbuckles for my Marquart Charger wing build.

    Eight per wing. I agree. Just over $1000 on ACS, so I'm hoping I can find some for a bit less. On the "positive" side, the AN150-16S is among the cheapest turnbuckles they list, at $33.65 apiece.

    Thanks Cameron! Request sent, looks like they don't have anything in stock.

    Hah. If I order the individual AN155 and AN161 parts to make up an AN150-16S on ACS, the cost is cheaper than buying the AN150 assemblies. Not a lot, $974 vs. $1072. Still. Pricing is hilarious.

    Point of interest: Part Target (parttarget.com, a random reseller I found via web search) quotes me 32 AN150-16S turnbuckles for $41.95 each, so ACS at least has them beat. I'm guessing this will generally be the case for this type of reseller.

    Ian,

    If you go with the AN assemblies you will have to safety wire them all. Many of the AN parts have been superseded by MS numbers.

    If you were to use MS21251 barrels and MS21252 Clevis forks you would have the same assembly, but could use the locking clips. I have been going over this recently and am ready to order some of this stuff as well.

    Try B and B aircraft if you have your heart set on the AN parts. They may have all you need at a better price.:cool:

    Thank you! I figured they would have been superseded by now, but I wasn't having luck finding the new number (I also didn't search very hard). At ACS, the MS parts are a bit more expensive than the AN parts.

    I have no idea whether lockwire or clips would be a better choice inside a wing, though clips surely sound easier. Given the timescale I'm working on, adding lockwire to 32 turnbuckles isn't a noticeable delay. Are there other factors to worry about, particularly since I'm unlikely to have easy inspection access?

    I did have a thought that they are easy to adjust and safety wire when the wing is open. If you had to make an adjustment after covering it would be hard to
    re-safety them (even with access holes). The clips might be more manageable in that scenario.

    Oof. Just put together the ACS order for wing hardware: just shy of $1300 before shipping, with $1010 of that being turnbuckles. I know, building planes is expensive. ;)

    I've got the MS style turnbuckles on the list, just to stick to the thread topic. They're slightly more expensive than the AN style (which would be about $975), but I figure hardware is a weird place to save pennies.

    I suppose the advantage of the Charger wing design is that I will never have to worry about cracked drag wire corner blocks.

    Ian: The MS units with the spring clips are much easier to deal with and the increased cost will balance out not having to mess around doing the safetywire the others need.

    Now I'm curious: other than the locking clips and whatever changes are necessary to support them, how are the MS and AN numbered turnbuckles different? Sounds like maybe stress-relieving is required on the MS parts which might be skipped on the AN parts.

    Turnbarrels are very heavy.
    I'd find another way.

    AN/MS is just the old/new identification method. Same same...

    AN parts require safety wire, while the MS parts can use safety wire or the spring clips.

    On clips. Just remember the ends that screw into the turn buckle also has to be the newer style with the groove for the clips. (Probably knew that but if you already had the old style I wouldn’t be buying new just to use clips. The new turnbuckles can be used with the old non grooved male parts etc. etc)

    Thanks. "Luckily" I have no existing stock, so I'm buying all matching parts. :D
