Hi. I am having trouble finding the advice on the 25pdr. forum about how to rivet the shield. I have glued elsewhere but the shield can be seen from both sides. I have a the correct tools but a bit of advice would be helpful before I waste any more rivets.

It’s much easier if you have the right tools, the appropriate rivet snap and a ball peen hammer. Setting a rivet involves three stages:

- hold the rivet snap vertically in a vice, place a rivet into its hole and place the rivet head into the rivet snap.

- using the ball peen hammer, start to form a rolled edge around the protruding shank.

- to finish, either flatten the shank or using a second snap, form a dome.

You may have to shorten the shank to leave It should have the equivalent of the diameter of the head protruding beyond the surface to be riveted.

This post shows it all:

Hello Graham,

I only want to add the formula for riveting, then you have the condition for consitent rivets heads.
long of rivetshaft = both sheets + 1,5 diameter of rivetshaft
Have fun building, Kind regards

I didn't have the correct devices, so I drilled a shallow hole the diameter and depth of a rivet head in the end of a soft steel rod, then clamped it in a vice. I then set the rivet where it needed to be, placed it in the hole in the camped rod and used large nail set with a conical indent to expand the rivet. One hit and the rivet is well set. And leaves a consistent back side shape. I cut reduced the length as stated above.

Hope that helps.
