joins for a criss-cross shape
I am making a thread rack for my spools simialar to this one (Cedar House Sews: Threading Up), except with a criss-cross base instead of a square. The vertical part that holds the spools is a piece of rectangular timber 3.5cm 2 x 50cm length which will have drill holes for dowel pieces to hold the spools.
The original plan was to have the base as a criss-cross except I am having trouble figuring out a way to join the criss-cross and place the rectangular rack vertically in the joined base. I don't want to simply nail/screw the pieces together as I want something that does not add extra height. Any ideas? Could I make a rotating base?
Also how do I drill holes on all 4 sides at the given angle (60 degrees) and depth (mid-way) without them intersecting in the middle of the timber. does it matter if they do intersect? (the will be all on the same level). Would too many holes weaken the wood?
