[pianotech] Console Leg (Paul Milesi)

[Terry Farrell]

Wood epoxy? What's that? If it is epoxy, you DON'T need to clamp it firmly to get a good bond - and if it is not epoxy, then what is it?

I prefer to glue them off the piano because I can clamp them better and control the process better.   You could clean the threads inside the hole using the threaded stud or a thread of equal pitch and such prior to the glue hardening.  Wipe off the stud with paint thinner/mineral spirits or acetone (or some other kind of inedible carcinogen) and reinsert until the hole is clean enough to reuse.  OR wipe some oil on the stud, thread it in the hole and wait for the glue to set OR leave it in there and install it on the piano, stud glued into the leg and all.

HOWEVER, I’ve been told recently by a young man of outstanding talent with wood, that dowels tend to add weakening tension with the resulting cross grained expansion and contraction.  It looks like you’ve got plenty of contact area to provide a strong bond with out dowels.

If it defies being clamped, there’s got to be someone that has a brainy idea on this.  I’ve never had the problem.  I’ve seen rags wrapped around it and twisted tight with a screwdriver wrapped around the rags acting like a screw  .........  much like tightening fence wire.  That makes it a bit rough to clean up oozage however plus you have the bond of the rag to the leg to deal with.
