Jigs and splines

Here is a jig I made for gluing the book matched triangles together to make the 4 diamond shapes that comprise the seat.  Thin wedges fit between the pieces and surrounding stopping blocks to apply pressure to the pieces.  In this photo, I'm still using test wood, Zebra wood will follow.  I also made a jig to glue the diamonds together to make the seat.  I made that from one of the test seats, which was already of the correct geometry for a jig of this sort.  I cut some holes in the bottom of it, though, so I could keep an eye on the seams from both sides.  Finally, I tested a spline cut from Afromosia, cut with it's grain going the long way.  It split too easily, so I cut all the splines I will need for several chairs, with the grain going the short way, so that the grain bridges the joint.  The tricky part was to handle such small pieces safely on the table saw.  Click Here for a Flickr show.
