I came up with a slick litle way of making sure that my 360 blanks glue up nicely...
I took a field trip to Home Depot and purchased a length each of 1" square aluminum tubing, and 1.5" angle aluminum extrusions. They are the "thick" versions at 1/8" thick walls.
I cut several lengths of both so that they are matching. you will find it easier to work with if you make shorter sections. 6-8" max length.
Now, for glueing my herringbone blanks, I use Titebond-III wood glue. It does NOT stick to the aluminum (no mater how long you leave it there to dry), it sets up in 20 min, and the glue lines are almost invisible.
For the first step, I'll glue up several 90 degree angles and place the parts inside the angle of aluminum. Place the square aluminum inside the angle of the wooden squares that are being glued up. Then clamp the two pieces of aluminum together making sure that all of the wood squares are pushed "in" as far as they go to prevent gaps.
Then to glue the 2nd "wing" just place one of the already glued up angles of wood (2 squares) so that one of the pieces hangs off the edge of the aluminum angle. Then glue another square of wood in & clamp!
For those of you that are COMPLETELY confused by my descriptions, DON'T WORRY! I'll be posting pictures of this process when I get home tonight.
The 3rd step requires you to glue 2 of the 3wing glued up pieces together in order to make one layer of the herringbone design. This step I haven't made up a fixture for yet, but I have one in the works. Right now, I'm starting by glueing together 1 layer, and then building /glueing the following layers together right on top of the 1st. This ensures that even though the 1st layer may not be perfect, all of the other layers match this one perfectly leaving very few if any glue gaps.
I hope that this helps someone... Maybe one of you that's read this can help me design a fixture for the 3rd step.
Happy Turning,
