on the original wheel , did you only rivet once? When we try the rivets are not reliable. We know why, but have a difficult time mastering riveting!!

we took our andymark 6 in wheels on concrete for a day of presentations and by the end of the day brand new wheels were completely flat like yours

yes, we use plenty of rivets. never had any problems.

It was a parade that flattened these.

if you are not using a pneumatic rivet gun i suggest that you get one. they seem to tighten it up a lot more 70 or 80 bucks good investment use steel rivets to

I guess its a double whammy for me, lol, we use a hand rivet gun and aluminum rivets!!
We have a pneumatic rivet gun and i tried using it today but I need to practice.

we use a pneumatic rivet gun now, but have also had success with a good hand riveter. we drill through the tread and the wheel in one of the "dips" in the tread. when we rivet it by hand, I push down on the head of the gun real hard and a student runs the handle. If they get in good and tight aluminum rivets will work fine.

Once you get a pneumatic rivet puller, you'll wonder how you ever lived without it. It's hands down our best tool under $100.

Under $50 actually. By far one of my favorite tools to have around the shop.

When you factor in the cost of a compressor, it's not inexpensive. Unfortunately, neither of the teams I mentor has a compressed air line in their workspace.

A good hand riveter (all-metal construction with suitably long handles) works fine, in my experience.

If a team is doing rivets in any meaningful qty, spending a few hundred bucks for a nice riveter and small compressor is well worth it.

We had our first experience with an air-powered riveter this past year. Especially after doing the entire prototype robot by hand, I couldn't believe how we had survived without that tool. Made things go by faster and without less stress on a few select students ^^

Wow, someone sure has been using those wheels. We had a demo on pavement, but we limited skid turns, so by the end, they were only a bit worn down. Then we replaced them for an off season event.

I think it depends on what you mean by "meaningful quantity." If you're putting together a tube-and-gusset chassis, it's not all that difficult to do your riveting by hand. It's still faster than bolting the assembly together.

If you're doing sheet metal, I can see how it would be a real pain to have to do all your rivets manually.
