rivetting tools

As you probably saw, most are a toothed wheel set in a handle.  Spacing of the teeth will be closer for 1/72 than for 1/48.

Suspect that the double ones have a wheel at each end with different tooth spacing for two different scales.

Some folks use a needle set in a small piece of wood dowel or an appropriate size tiny drill bit to make rivet indentations one at a time, but that can get tedious.

I'm in the U.S. and got mine from Micro Mark, but that may not be an option.  Another item to look for would be a "pounce" wheel, used to punch small holes in a paper pattern then gone over with a chalk bag to transfer the pattern.  Should be available at fabric stores.

I use the trumpeter rivet tool, comes with 4 different sized wheels and works very well. Loads cheaper than some other ones.

I use the rivet tool from Revell, cost be 8 pounds. Comes with 4 size/scale wheels.

Thanks Steve, it sounds like thats exactly what I need.

The trumpeter one I have must be a copy of the revel one as they look exavtly the same.

Thanks Theuns. Given Revell's status at the moment I might have better luck sourcing a Trumpeter product.

Thanks Goldhammer.

I have an RB Productions riveter that attaches to the exacto handle and brings several wheel in different sizes. It's a great little tool to have.
