Beautiful job, i wouldn't expect anything less

I have to agree, "WONDERFUL JOB". 1 question for you, What is the wall thickness of the rim at the grooves? Would really like to see these in person They do look amazing. Are my eyes playing tricks on me or do the centers have an angle on the main body?

Thanks guys. I'm not sure what the wall thickness is. I know the grooves are 2mm deep so I am guessing it's around 1mm thick. Yes the hubs are tapered a little.

Thanks for the quick answers! Another ?? for you- Why didn't you turn the grooves in the wheels instead of milling them? I know, I know, lots of silly ?'s but this is the way you learn things

I find it to be faster than turning them in the lathe. I don't know if it is my setup/tooling or what but I can never cut the grooves in the lathe without galling issues unless I turn the stuff really slow. Even then I have ruined a couple of wheels when they were almost finished. In the mill I use a 1/8 cutter with the mill screaming. I use the drill to turn the rotary table and my right hand can steadily feed the Z axis down(slowly) with only the occasional squirt of alcohol needed for coolant. The wrong way to do it but it works well for me.

Your way of machining the grooves is not wrong. Just another way of doing it. I normally use WD40 or a cutting/tapping fluid for coolant. Never thought about using alcohol. Would not be as messy!!
