Re: Split Wood Columns

[Subject Prev][Subject Next][Thread Prev][Thread Next]
Agreed, Daryl, it is a bad situation, but the bolt holes are going to provide 
a surface for moisture to escape, and thus be a place where shrinkage cracks 
would initiate.  What to do about it?  I dunno, except maybe band the top of 
the column before shrinkage cracks develop, or let the column develop 
shrinkage cracks before installing the bolts (fat chance on this one).

A concern that I am developing is the capacity of bolts in actual field 
drilled holes, particularly where the member is thicker than a 4X and steel 
attachments have to be made on both sides.  Workers don't have drill presses 
in the field, and with hand drilling, it is difficult to have the hole 
spacing the same on both sides when drilling from one side.  Workers like to 
drill part-way thru on one side, and then go to the other side and drill 
until they meet the first hole.  The hole is then bellied out so that a 
straight bolt will go thru both attachments, or, in one case that I saw, the 
worker bent the bolt so that it would fit in an angled hole.

Buddy [Showalter], is this the way bolt capacities are developed for thicker 
pieces, real world style???
