    Turning small rivets into Bolts

    This is actually all about making a small chuck to grip the head of the rivet so that I could apply a torque and cut a thread with a die.

    The concave dish is important as this grips the domed head of the rivet

    The rivet balancing on the anvil side of the chuck

    The number goes over the shaft of the rivet and clamps the head against the concave form in the anvil side of the chuck.

    I can then apply enough torque to cut the thread using a die.

    The interesting bit is that these rivets are just 1/16 inch and the thread is 10BA.

    This is all for the miniature Burrell traction engine and allows me to temporarily bolt where rivets should go. They are rather fiddly nuts and bolts though

    Hi, an image of a packet of rivets:

    The calculation for the rivet length is important, I use 1.43x diameter, calculation is here

    These rivets are available in brass, copper and iron from EKP Supplies. Some 1/16th inch rivets shown here with my homemade punch using hardened silver steel
