Closure!

Leveling the Garland

Last time I posted, I had installed the back linings, shaped the blocks and linings, and was nearly ready to close the box. It looked like this:

The blocks and linings are shaped.

The blocks and linings are shaped…but the garland is not leveled, yet.

 

To the unassisted eye, the back of the garland really looked pretty flat. In fact, I had used a hand-operated abrasive tool (a Sandvik tool…they apparently went out of production, years ago…but I love the few I have) to try to level it all the way around, thinking it might be easier. But when I clamped it up, to test the plan, it was not even close to level…so, back to the sanding board!

To level the garland, I made pencil marks all around the mating surface of the garland, and then rubbed the entire structure on the abrasive surface until all the marks disappeared. Presto! Flat!

 

Installing the Back Plate

Then, while the glue was heating up, I carefully went over the perimeter and inner surface of the back plate and made sure the curves were smooth and consistent. Once I was satisfied with it, I carefully aligned the back plate on the garland, pushing and pulling a little to get the overhang even, all the way around. I clamped only at the blocks, initially, then began using a thin-bladed palette knife to insert glue into the joint. I removed the clamps at the bottom block, first, and inserted glue so that the joint between the bottom block and the back plate was fully coated, then slid the blade left and right, as far as it would go, spreading glue on the joints between ribs/linings and back plate. I quickly reapplied the clamps at the bottom block, and added more between there and the corners. Loosened the next set of clamps, and repeated the routine.

Once the entire perimeter was glued and clamped, with an extra clamp at the button-to-heel joint, I could set the whole assembly aside to dry. It is closed!  (I really like looking at that one-piece European maple back.) 🙂

I will let the glue dry overnight, then remove the clamps and trim the heel to the correct profile, trimming button to match the heel, so that they are shaped as one unit. Then I will carve the slot in the back plate for purfling, install the purfling, and, finally, prepare the whole instrument for varnishing. I hope to be ready to begin the finishing process by this weekend.

 

Thanks for looking.
