I recently started working with leather and sometimes i need

I have this piece of pig iron from a blast furnace ground flat for tests, but i have no idea how to produce a spherical depression in that. If i cast the needed shape in two-part epoxy, would it have enough strength?

If I understand what you're trying to do wouldn't this work?

>The thing is, when i put the rivet head on a wooden surface, it tends to deform when the pin strikes it from the inside and that looks nasty

Wait what is deforming? the wood the leather or the rivet head?

Google for 'rivet anvil' for the size of rivets you're making. What's strange is that they didn't include one.

It still makes a depression, but my set came with a tiny little block of oak that's can probably take a couple hundred rivets.

Could you use a piece of cork over a piece of soft wood?

This, I use a couple layers of study scrap leather over a small anvil to take the brunt of the force. Works pretty good.

These would produce a depression, but its radius would be too small. I was thinking of something along R40.

The rivet head, it becomes unsightly. Pic related.

A friend gave me the rivets. I know i could buy a rivet anvil, but i'm just starting out and it's relatively expensive. Expensive as in "30% of what i typically sell a finished good for". I don't even use rivets all that often, but sometimes it's limiting to not be able to use them.

I tried combining wood, cork and leather as well as all of these by themselves. Didn't help.

Maybe the picture will make my problem clearer. The heads have a 7mm OD. Left to right are two set rivets, a head and a post. As you can see, during setting the post deforms the head from inside.

You could hammer a coin into a concave shape if you had a ball peen hammer and then use that as an anvil.

Thanks, that's a great idea! I'll do that and stick it to a backing piece of wood.

Use a lead block. Lead defoms instead of the rivet.
