Pedals

[Roger Jolly]

Hi David,
         Save yourself a lot of work by using CA glue. Tape the bottom of
the crack with PVC electrical tape, so that it will not ruin the finish. I
prefer the hot stuff brand. Use the thin viscosity to run down the sides of
the glue joint, and the the ultra gap filling to fill the cavity between
the shim and the side of the hole let dry or use accelerator. Finally use
the thin on the end grain of the dowel. The procedure works well with the
leg and the console.
  Before starting, place a block of wood on the top of the assembly and
give a few good whacks with a hammer, to ensure the horizontal piece is
firmly seated.
  Leg and lyre seperation is very common in our dry climate, for the past
three years we have been applying Red Hot Stuff to the end grain of the
dowel. It seems to prevent shrinkage, and as such we have had zero
failures, since adopting this practice. Prior to this we were running about
50% failure in the first 12 to 18 month period.
  You will probably be suprised at the amount of glue that will run into
the end of the end grain.
Hope this helps
Roger
