I've used tools and rivets from these two companies - Hansen Rivet and Supply
https://www.hansonrivet.com/ and Jay-Cee Sales And Rivets inc
https://rivetsinstock.com/ for many years. The advantages are their large rivet inventories and many types of rivet tools and dies. I've adapted their rivet dies to be used with a Harbor Freight arbor press that was used to restore 64-66 ash trays and several radiator grill restoration.
That's just for cars. I made some heat shields for my outdoor grill.
The "fun" part of this is figuring out how to do something today that you thought was impossible yesterday.
