Alex Christie, moderator of the Origami Boats mailing list, recently put together a little video review of a Switchable Magnetic Ground Clamp. Looks like it could be quite handy if you’re welding, especially metal plates.
Note that Alex also produced what is supposed to be a very nicely done DVD package showing the build sequence of a Brent Swain Origami boat. I haven’t seen it, but plan to order it:
…there is still available the 3 hour DVD set detailing the construction of an origami boat from flat sheet to bare hull, cabin and decks. $54 USD, shipped worldwide. Contact me at [email protected] for further details if interested! Alex Christie
