proper build up beam method
was wondering what the prescribed method of building up beams is. just as an example:
lets say you need a 20 foot two member beam supported only at each end and can only get 16 foot or smaller lumber. i'm thinking you would want the splices a far away from the center as possible so would basically overlap the 16 footers and with 4 feet added to each end
is this the strongest way - would you glue and nail - through bolt - angled scarf joint, regular scarf, butt (if angled scarf which member would be lowest point).
thanks for all replys.
