Hi, Stiglr!
Thankyou for replying! I've a very good idea of how it's shaped, as I had a kit with these same style rims for years. It does sound fiddly, if I'm honest. I was hoping there would be a way of making one piece and revolving it or something, but not to worry!
I'll give it a try and see where I get; I'll have to blow the dust off that project soon, lol! I'm sure you've seen that I'm working on other things at the moment too, but as soon as I get fed up with those, I'll get back to my drum kit. It helps to have a few projects going at once, so I never get too fed up with something, lol!
You're a legend man, thankyou very much!
