I wasn’t totally sure which size would be best, but now I have them I thought I’d do a guide for people incase you guys are looking for some.
0.025" - This size is tiny and I really wouldn’t recommend going any smaller to be honest. I’ll use these for rivets on 28mm sized models, they’re probably a fraction bigger than the tiniest rivets you’d see on GW plastics.
0.030" - This size is quite manageable, I bought 600 of them. I had planned to use them for warmachines, whilst they would be good for that, I think they’re a little bit small for what I want them for. A good size for handling though.
0.040" - This and 0.050" are what I would recommend for anyone thinking about scratch building a wagon for the steam train, as I will be eventually. The 0.050" are about 1mm across as a guide.
Forgot to say that these rivets are the cheapest I could find, and I did a fair bit of research. Metal ones are twice as much for an eighth of the amount!?
