    Anyone know what the correct size solid Aluminum rivets are for Series body parts.
    3/16 by 1/2 length
    3/16 by 7/16 length
    3/16 by 3/8 length
    What are correct sizes.
    How many roughly required for entire series.
    And do we have a supplier in SA.

    This is going to be interesting to me Imgreg. My series has pop rivets but you are obviously busy with a restoration. Maybe you need to check the material too to prevent galvanic corrosion?

    Not too familiar with the technicalities of the series.

    But rivet lengths will vary according to amount of metal being fastened.

    So you can buy the longest and trim them to the correct lengths before bucktailing them.
    If you need to calculate the required length that protrudes, I can ask a colleague.

    Are you going pneumatic with bucking bar?

    Oh... and talk to a aircraft structural worker(sheety)

    They can help you with a lot of the questions you have.

    That's a 4.8mm rivet, so it's max.
    If you can use smaller, please do as you can always go bigger.
    Use a 4.9mm drill bit for best results.

    Speak to David Kinghorn (JLR Spares) about those rivets. As far as I know, you have to buy the correct size...., cutting them to size is a pain.

    Ja, sorry I'm used borrowing the Sheeties tools.

    They have a nice rivet cutter

    There is a place at Rand Airport (or was, I'm not sure) called USATCO, they sell aircraft structural tooling, so you will find rivet guns, snaps and bucking bars, rivet cutters and all sorts of drool inducing toys there at frightening prices.
    They may well have rivets, too.

    Buy the longest rivets you will need, add 1/8'' and cut them to size as required is my advice.

    The Adendorff guns and similar may cause trouble, they have a very harsh stroke delivery, I'd suggest an inline flow reducing adjuster like this...



    You will need the correct snaps, though, those will not be easy to make unless you have some fancy tooling and materials. The rivet head recesses are polished and hardened, and so are the shanks where the piston seats. Normal rivet guns are a .410" shank size for the snaps.
    Here is a 3X size gun with snaps and some bucking bars... Don't get anything smaller than 3X as you will struggle to drive the rivets with a lighter gun.

    Yours for Euro +- 340.00

    As for the actual riveting... there are basic rules, but as your Landy already has the holes drilled, you just need to follow that pattern.
    Here is a chart for shank lengths and finished dimensions if you want to get really technical.
    There are also options to put washers over the shanks if you need to, then obviously the rivet length increases by the corresponding thickness.
    The top diagram should apply to your needs.



    Have a read here, for an idea of how the aviation guys do it.
    https://www.aircraftsystemstech.com/...tructural.html

    Buy the best drills you can, drilling the heads off if you don't set correctly can be a pain with a marginal drill bit as it will wander on the round head and then end up off centre to the stem position.

    If you mess a hole up, there are rivet versions of these bolts available, but they are eye wateringly expensive...


    Rivets work harden, so find out about how to treat them prior to fitting them and the time between treatment and fitting as they can also start to harden while they wait for you to get set up and start, depending on the alloy used and the hardness level.
    Cheers,

    For the life of me I just can't see why those special bolts are so expensive Johnno. Most holes are shaped like that.

    Have used rivets designed to be waterproof before. You have to get the correct length but if you "gasket" the head side and insert, the moisture can't leak inside. Roofing people use them in certain cases. Especially when you cannot get to the back.

    Would be interested to hear comments.

    I've got this bag of rivets that I got for a project many years ago. The project didn't get off the ground so if anyone can use them make me an offer. Click image for larger version.

    I will be keen.
    Let me get a price per 100 in the morning and make you a fair offer.
    They are very long but can be cut shorter.
    I need 3/16 x 3/8 around 10mm long.

    Edit, might be too small for me as 3/16 is around 4.7mm
    Those are near 4mm. Will Have to make sure.

    Yes they are one size smaller than what you need.

    I'm blessed with a aircraft structural worker as a friend.

    He has everything.
    These were done with a pneumatic rivet gun and bucking bar.
    The other, on other parts, were done with a pneumatic rivet squeezer.
