Beautiful work, as always, Keith!!!
Ceboplast is one of my all time favorites. BUT, when you are fortunate enough to find a rod (more scarce than "hens' teeth" for a while now), the rod is difficult to make anything much bigger than a designer pen.
My hat is off to you, sir! When I get a chance to attempt Ceboplast, I use sandpaper, from almost beginning to end. AND VERY LITTLE TOOL WORK! Not that it is a difficult material, but because I fear one shop "interruption" could render it useless and it is so hard to come by.
This, my friend, is a masterpiece! I don't think I'd have the guts to even drill for a Churchill!
