Pretty cool video!  Thanks!

I always wondered how URW characters managed to put together things like tables and chairs without the use of nails, using only axe and knife...
I guess it would be possible to bore out holes for wooden nails using a knife... is that meant to be the idea?  or is it more like tenon joints?  Perhaps an expert on Finnish/Scandinavian woodworking could clarify.  Or one of the developers.

I recall from my own limited carpentry that the wetness of the wood will matter. Dry wood is smaller, wet is bigger. So it could help to dry a peg before insertion so that when at average wet it binds more.

Plus under load the hole will deform and so should the peg. The deforming of each is slightly different so may improve binding when sitting on it.

I do recall that to take apart broken furniture to repair it was good to dry it (make things smaller) and no load strain (often upside down, or in an oerintation it wasnt built for)

Knife cut holes tend to be very sloped as most knives go from a sharp point to whatever width. Actually making a drill or auger takes about a simliar amount of metal but rather than putting a knife handle on it you extend it as a wood rod farther back. Then this rod  you connect to a cross bar to generate the turning force.

Found out about that research the BAC items for Medieval Drill and Auger.

From the BAC discussion with weblinks:


////////////////////
// Auger
//
// Used to pre-drill holes before using nails
// or wooden pegs. Expected only for large construction
// or joining thick pieces like in boat building
//
// Differs from drill in that the auger makes finger or thumb
// diameter holes such as for structural wooden pegs
//
// A carving axe or knife would would do in for most boards
// if you can access both sides. If the board is already in
// place you might use an auger to drill from the open side
// all the way across and then into the other wood.
// Presented as one recipe
