[Cob] lifting vigas, a picture is worth 1000 wordsocean ocean at woodfiredeatery.comTue Sep 27 23:09:50 CDT 2005
Hi Judith, We lifted the 600 lb ridge beam of the cob kiva using a stepped-scaffold (to see pics, click http://www.peacemaking.org/liftingridgebeam.jpg ) and the labor of 14 willing hands. It helped to have the cob wall already built to a height of 12 feet to lay one end of the beam on. The middle pic shows the stepped-scaffold, where the guys are standing on the loft and lifting the beam onto each successive step, taking a break between heaving, until it is nested in the crotch of a tree post (as seen in the bottom pic). (In the top pic, the beefy bearded guy in the front is Oleg, a robust Ukrainian friend who at one time seemed to be holding the entire beam up under his shoulder! I'm the guy on the other side of the beam from him.) The tripod and block & tackle mentioned on the coblist sound like a better way to do it, but still you'd need advice on how to construct the tripod, size the block, etc. Then again, there are small cranes for rent from our local building outfits. Whatever you do, make sure everyone is safe, with adequate safety ropes to prevent a catastrophic accident. Good luck!
