I thought I edited the whole response .....gone. But didn't. I typed before re-reading the original post. Thunderbird was the ;last phrase that did not register.
I apologize........I neglected to add when using the 1/4" square stones...........I use alcohol as the cutting lube/wash. It does a good job. Followed with 400-then 600 paper.
I use the Gesswein 600 1/4x for rough areas and it works well. To follow with 400,600 etc. These stones are best bought in the box rather than individually I think due to pricing
it was shot under a white/cream sheet tying to follow TOS"s protocol. With no camera stand or square in front the draped sheet it is still problematic. I am working on it. Thanks for all the pointers. Rob
