Scarfing the plywood

Getting a stack of plywood ready to scarf for the planking.  



First rough pass with plane.  



Almost finished.  This method of doing a whole stack of ply at the same time is so much better than the ways that I have tried it in the past.  I can't believe that I now have all of the scarfing out of the way, as long as I don't mess up any of the planks, that is.  It didn't really take long at all to plane this stack down.



Ready for some glue.



Joint is painted with straight epoxy first, then one side is coated with thickened epoxy.  I made my batch a little thicker than I should have for this task (not shown in these images).  It should be thin enough to squeeze out from the tight joint easily.  I read the "pancake batter" description in John's book just after finishing gluing them up!  In any case, they came out better than any I've done in the past.


The whole stack is clamped down with a board.


After congratulating myself for how easily I accomplished this, I realized that I was confused while lining up each layer, and I found that my clamp was not placed directly above all of the scarfs.  I then added another board and put some very heavy flat concrete blocks on it and hoped it would clamp everything.  It all turned out ok, but could have been executed a little better.
