Having cut the scarf joints yesterday, today the first pair were glued together. The glue used was West Systems epoxy with 5% by weight of 403 microfibres added to improve the strength and gap filling properties of the mix. For a small area like this the fast version of the hardener (205) was used with the standard 105 epoxy. First a piece of plastic was taped to the bench under where the glue joint would be positioned. Then glue was applied to the two mating surfaces. Staples were fired through some scrap wood to fasten the first piece of plywood to the workbench. Then the second piece was positioned with the scarf joints overlapping and more staples used to hold this in position. Excess glue was carefully wiped off the joint. Left overnight to set, the two pieces of plywood magically became one!
