Assuming readers know what a rivet snap is and that you need one on each side in this case. The one linked has two 'holes' because one is for setting the rivet first.

Once you have found the length required as Jason says abovethere are lots of designs in old MEs and online for ways to cut them all to the right length.

I've recently almost finished riveting my traction engine wheels; two rear wheels to go. For scale the following are 3/16" steel rivets. First you need to practice:

The practice rivets also allowed me to experiment with rivet length. I found that the length was critical to get a nicely formed head, certainly within 10 thou and preferably 5 thou. The actual length will depend on the rivet snaps. I made all my own snaps from silver steel, hardened and tempered. The business ends of the snaps need a slight chamfer so if they're not quite square they don't mark the work. I also made my own riveting jigs. It is important that the snaps are held in line and perpendicular. Here's the front wheel being riveted:

I used a flypress but for 3/32" rivets you'll probably get away with a hammer. Here are the formed heads; for comparison the rivets at the top are the commercially formed heads of the rivets for the steel tyres:

This is the riveting jig and more snaps, plus the setting snap, for the rear wheels:

Riveting the rear wheels, it don't half hurt when you drop the wheel on your foot:

These are the formed heads on the rear wheels, not quite as good as the front wheels. But full size isn't perfect either! The T-ring has bulged slightly as the rivet shank expanded:

And the two rear wheels finished:

Any questions?

Andrew,

Tell them the wheel diameter!

Hi,

I refer to your message earlier, giving out your email address for scammers to see.

Try to remember to PM that sort of info to the target person, then it won't show. Hope you don't mind me messaging you like this but I only mean to be helpful in a friendly way. There are more than enough toerags about.

Rgds,

John

Nice work there Andrew.
