I've only recently found your site. So I apologize if this question is something you've answered in another post. When you work with the milliput, do you need to occasionally dampen the carving tool to keep it from sticking to the milliput? Thank you for these "apocalyptic" creations. I hope to make use of your ideas in a table top game.
Both is correct. It depends on the exact shape of the beam. Is the width as long as the height, than is it a H-beam, is the width far smaller than the height, than it is I-beam.
