Riveting Clutch Linings

I'm just about to fit some new clutch linings (3-speed box) and have realised I don't have any tooling to sett the rivets.

I do have a suitable piece of steel rod which I can use to support the head of the rivet but to swage out the hollow portion I guess I really need something like the tools used to fit eyelets into leather.

Has anyone tried simply using a tapered punch to begin to open the hollow end and then something like a ball pein hammer to spread it out?

Although I suspect the strength of the rivet setting probably isn't that critical I'm more concerned about damaging or cracking the new linings.

Any advice?

Yes, many years ago, but that is what I did - I think it would have been a fat centre punch, then a ball pein hammer and finally a flat punch. Don't miss as the material is quite fragile, and no need to squash the hell out of them. If the rivets are 'old' perhaps anneal them first by heating to dull red and quench in water, but listen to what others say as well.
I use a half inch bar ground to a 45 degree cone on one end and a dome headed M8 bolt to finish off.

Done with a small - 2 oz? - I have just been to check and the marking is worn off - hammer.
When I replaced the clutch linings on my Ten, I visited a local brake and clutch relining firm. This worked out rather well, as it turned out that the copper rivets supplied were of the wrong length and a rivet hole in one of the linings hadn't been countersunk. They were able to address both of these issues with ease.
I turned a tool with a pin to fit the hole in the rivet, followed by a curved shoulder to spread it. Only mild steel, but very simple and effective for a one-off job.
I used the tools used to fit eyelets into leather they worked well.

I have just fitted the linings to the flywheel and only having two hands, I bolted up the un-lined clutch disc onto the flywheel with the pressure plate as a clamp using old camshaft bearings as spacers under each rivet head & between the disc, so that these were held firmly in position, then the flywheel became a solid mass & effectively an anvil, and it was easy to hit with rivet snap tools to open & then spread the head. Worked a treat!
