Introduction Edit

Field frame bars and rings should be riveted together after the pi-brackets have been riveted to the field frame bars and after holes have been drilled to the rings.

The process Edit

First form the shoulders to the ends of the field frame bars. Below I've used a combination of hacksaw and files; a much faster option would be to use an angle grinder. Even better and faster would be to forge the shoulder, but that requires tools which I don't have.

Next make the holes to the rings. Here I've used the laborious method of drilling a round hole which I then filed rectangular. The location and alignment of the holes can be made easier by using a metal template.

Adjust the tenons and the holes as necessary to get a relatively tight fit and correct field frame alignment:

Now polish the rings. To make that easier you can make a simple wooden template which has two screws for keeping the ring in place:

For polishing I used 120 and 240 grit sandpaper wrapped around a sanding block, and finished the polishing with a steel wire brush:

At this point the ends of the tenons are still fairly long, which is problematic, especially if the field frame bars are made from spring steel or such, like here:

Therefore cut the tenons fairly short so that the heads of the rivets are easy to forge:

Forge the head using a heavy hammer first. This tightens the sides of the tenon against the hole. Then use a smaller ball-peen hammer to form the actual head:
