    Hey Guys,
    I priced some "Flush Pop Rivets" from a local Company ( Stainless )

    Holy Cow... They said 21 cents EACH...

    I was surprised that ACS was CHEAPER.... But they are 14 cents each....

    Still too Rich for my Blood....

    I thought .... Why can't I RE shape a regular Stainless Rivet ????

    I was so shocked how GOOD my first one turned out....

    I had to double check to see if I accidentally had grabbed the Stock Flush Rivet...

    HA !!!!!!!!!!!!! To my surprise , these things are EASY to change....

    That means "my" flush pop rivets are about 2 cents each....
    .
    Here's how it's done....

    In a plate of Cold Rolled steel.... I drilled an 1/8" hole for the rivet to sit in....

    I countersunk the hole , to give the rivet "head" room to move....

    I drilled out a piece of Mild steel Round Stock....

    It slips over the other part of the rivet... ( Stem ??? )

    I got things into position.... Gave it a light tap... Wala...

    Instant Flush pop rivet....
    .

    After I found that it worked good... I made a better bottom die...
    It can be held in a vise...

    PS The rivets in the pictures... "ONE" is a flush rivet...
    The other two were "re-shaped"...

    They were the first ones.... The new jig does even better...

    Have you noticed any impact on the performance of the rivets since you've been using this process?

    Would be interesting to see how they hold up to a test, seeing as alloy work hardens so quickly.
    It would also be interesting to review the practice against AC43.13

    For non-structural applications mind you, brilliant idea!!

    It seemed odd to see your post planecrazzzy because your tools are virtually identical to mine.

    My mate Baz made me the set pictured here 25yrs ago and I've used them regularly ever since. The screw together dies are also ideal for dimpling in hard to reach places.

    Also here is a picture of some converted rivets installed on the instrument panel support frame of my current project AussieMozzie.

    I Just noticed this post... HA !!!! They do look alike !!!

    One thing I did on the Bottom die was put two "Flats" in it , so it could be held with a vise...

    But there really isn't much force needed... Just a Tap with a small Sledge is what I use...

    I wonder why they don't SELL something like these...

    Kind of ironic because Zenith does it the other way around- makes protruding head rivets from flush rivets by dimpling the nose of the pull tool.
