Tim,
Haven't noticed any cruck creep yet. This cruck frame will be going to Vermont after we raise it at Heartwood, so we're spreading the load around.
All hand tools except for chainsawing. We will axe and hew or adze the curve on one of the cruck pairs and ties and then use a chainsaw jig to cut another pair, just so people can see both methods. The flat sides of the crucks and ties will be pre-sawn by a WoodMizer and then cleaned up with smoothing planes.
