First off the Magic Sculpt wheels got armored wheel cover sculpted out of straight Greenstuff. I like the effect but I might go to a composite putty mix so I can get sharper edges. But there is a bunch of work still to do so we will see.
The blank on it's side as well as the blank that looks like a white circle are made out of the composite putty, 50/50 Magic Sculpt and Greenstuff. It machines much better than the Magic Sculpt. So further blanks will be a mix. Though I haven't tested out Procreate yet so I reserve my right to change composition.
Lastly the 2 metal wheels on the bottom are from GZG's, I tossed them in for a rough visual comparison.
These are the main tools I use to do the rough shaping of the blanks. The Pen shaped tool is a cheap carbide tipped scribe (a'la Harbor Freight Tools, if you have one of their stores near by they are wonderful source of cheep tools and other weird stuff).
The Dremel Stylus is about the most useful of all my rotary tools. Small enough to be very handy, but heavy enough to stabilize well in my hand.
And a quick note on my camera, I am using an IPEVO document camera it works like a charm. my biggest issue is figuring out the proper lighting. Right now I am using a combination of a desk lamp with a CFL and a little portable LCD OttLite. I think I need better reflectors. As always it is a work in progress.
