Hi Brad
I'm heading out in a few minutes to the SAPMA Exp, Sunday morning. I haven't seen the modeling folk for a longtime. I'm not competing this year but it will be great to see what's on the table.
I built a few 1/48 models many years ago and used Toms Model Works PE wheel sets. I find 1/32 scale pushes the scale limits with wheels, spoke circumference, rims et cetera. Haven't really attempted to make any in 1/48. It would be great challenge.
I don't share build logs / tutorials on making wheels anymore because I sold a few wheels sets over the years to buy modelling tools. The 3D printing guys have some nice images / renders of what's in the pipeline. Maybe they've got some 1/48 wheels planned.
