Alternative to an air chisel?

Hi,

Has anyone used a cordless (or corded) impact hammer or rotary hammer to remove the rivets from the exterior of their bus?

Just curious as I would rather not want to invest my limited space in an air compressor at the moment and I think a buddy of mine has a Milwaukee 18v hammer drill with a chisel bit.

Before I ask to borrow I just wanted some perspective in that approach.

Thanks in advance.

I’ve gone the air chisel/compressor route and honestly not worth it. Get a 1” chisel (for metal obviously) and use your grinder to get it halfway decently sharp. Use that and a 2-3pound one handed sledge hammer. Two hits per rivet, it ends up being faster than the air chisel. Free work out too!

We went the air chizel route as well. It was less work on my own body, but it wasn't any faster than doing it by hand. It took me 6 hours to do all the side panels on our 40' bus.

Put my name in for a hand chisel, they work well. However, I have not tried an air chisel so I have no comparison.

You folks are obviously doing something wrong or missing something.

Punching out the center mandrel and shearing off the head I can take the ceilings out of a 40' school bus in a couple hours total.
You can't use a tiny air compressor. You also have to press the air chisel hard against the rivets.

Hand hammering/chiseling all those sounds horrible and silly to me.
