Holes and Riveting

A 20v cordless drill is handy. Make sure you get a quality one with a lithium battery to ensure long life and quick charging.
A 6 to 10 amp, a heavy-duty corded drill is great for polishing wheels. You will a cordless drill is just too wimpy for these tasks.
You will need a collection of metal bits. I find 3/16 is what I go through the most. That is the size for most of my rivets. Buying a pack of bits of the size you want is more affordable than the multi-packs. At first, you may break quite a few as you learn how to drill straight and not bend the bits. Sheet metal/auto body bits are handy because they are shorter and have bits on both ends.
A metal hole punch is a handy tool. Make sure that the one you get can handle 14 ga steel.
Finding a solid rivet supplier can be a challenge! I like 3/16 x 1/2 inch long rivets with a round top. You may also need some 1/8 inch rivets 1 inch long for face grills. I purchase packs of nuts and bolts of the same size as the rivets to use for temporarily holding pieces together. Don’t try and use pop-rivets, they are not strong enough and are not SCA legal.
You will accumulate a collection of rivets, bolts and washers.
If you don’t want to spend the money on rivets, you can buy common nails and cut them with a bolt cutter. They aren’t pretty, but they work just fine.
1/8″ or 3/16″ bolts are handy for holding your project together while forming it.
Round-head rivets are pretty on a helmet.
