I have a HF wheel set. I am abandoning the upper for a 9" dia. 5" wide design nearly half completed now. Wheel rim has .750 wall. Thinking abt CNC lightening flutes in the edges of the ID for hand grip to start motion at times. Will post pics when I figure out how to post. Reading . . .

The wider wheel is both a blessing and a curse. Yeah, it holds down on marking but it also limits access to the panel for little things. Personally, I don't see much need to go over 4".
As far as wheel weight goes, I don't notice a difference that matters. On my big machine, the upper weights about 80 lbs and is 4x10. Because of doing some customer work that needed a better finish, I recently swapped it out for my 4x9 Hoosier which is about half the weight. I didn't even notice a change.
Of course, you can't believe EVERYTHING you read on the internet..

Will require locking adjusters both top and bottom. Quickchange will happen from that point outward. Still thrashing the QC design. Ideas?

Be interesting to see this machine being built. You're obviously an engineer.
I'm not a fan of multipurpose tools. Just too inconvenient to swap back and forth for my taste...everyone to their own thing. With a frame that large, you've got lots of room to hang other things on the rear legs and back of the frame.
