I recently saw on Youtube a chap had riveted his wheels with "blind" screwed round head screws, these were nutted on the inside, he then used a Dremel tool to round off the rivets. I have followed this idea as I was a bit worried about riveting the spokes. My question is that the nutted screws look OK to me without being rounded and they are not very visible being in the inside of the T rings. Just wondered if this has ever been the practice in full size? If it is "acceptable"in a model?

Steam Traction World do something similar with nuts that are "domed" so you just have a very small amount of hex

I would expect that the full size machines were riveted with hot rivets That way the rivets deform to the hole size and grip more tightly by contraction when cooled.

An old tractor, I have, has a set of spade lugs (bolted on the steel rims).  It had a fair number of lugs which had come loose and were either bent and/or had enlarged the bolt holes in the rims. This is an agricultural machine but would occasionally have been driven over hard standing - really uncomfortable for the driver, so not done at speed! Some steam engines may well have been used on metalled roads for a large part of their lives.
