[1] In steel shipbuilding, the entire frame can be formed in one piece by rivetting or welding sections; in this case the floor remains a separate piece, joining the ...
The log would then be finished internally, with all the rebates for fitting bow timbers, transom, washstrakes, and holes along the sheer-line cut. As the final step, bow and stern timbers, which were separate pieces from the hull log, would be caulked with moss and the whole structure made watertight.

The log is placed across two other smaller logs near the ground or up on trestles about waist height; stabilized either by notching the support logs, or using a 'timber dog' (also called a log dog, [4] a long bar of iron ...
