verticals were grouped into pairs, and double taped so the outsides will be face to face (this way the hole will be nice and smooth on the outside). it is important to mark the pairs as the drilling is never the same unless done together.
all nice and drilled
i did not take pictures of the next stage. you dry assemble the uprights and he beam and mark where to drill with the same bit. again, it is important to keep orientation and affinity to the pair that used for the marking.
drilled on the drill press, made some threaded rods, used the nuts from last time and voila!
it is rock solid!
next i will put some finish on (combination of tung oil and white oxide, wiped off and left to dry)
-- The woods are lovely, dark and deep, but I have promises to keep...
