Thick CA works very well when finishing cobs and only takes seconds to cure. Living in the land of "pink snow" I have done far more cob pens this way than I care to count.
Thank you, Tim, for putting on this instructions. Specialy interesting is the part on gluing the tubes. I was goint to use PU, but now will probably go with CA for gluing, when I do my first cob pen tommorow.
