Thread: Bleeding huon pine veneer

Here is an example of how epoxy bled through the birds eyes on a 2mm thick sheet of resawn huon pine veneer.

There are two sheets of 500 x200 x 2mm resawn houn pine that I was veneering on to a matching 9mm moisture resistant MDF panel using Techniglue epoxy. The two sheets were then covered in non-stick paper and fitted between two Melamine cauls, all taped together to avoid movement of the veneer sheets, and then slid into a vacuum press for 8 hours while it cured.

The epoxy was spread on with a V shaped adhesive spreader, then brushed with a disposable foam roller. The first side was done neatly and thinly, as shown below.

The epoxy on the 2nd side was laid on too thick, and it oozed out of the sides and got between the nonstick paper and the veneer top surface. In addition, after it was put in a the vacuum bag, it forced the excess to bleed up through the birds eyes of the huon pine veneer.

Fortunately the excess epoxy sanded off the surface of the 2nd side, but not sure if the epoxy has been also forced into the fibres surrounding the birds eyes, thereby preventing absorption of the oil finish around these special features.

A lesson for newbies about bleed through, eh?

The other lesson is that the resulting lid panel 500 x 200 x 12mm is relatively heavy, and may require three butt hinges instad of the two SmartHinges.

In hindsight I should have used 6mm MDF, but you cannot buy it moisture resistant in this thickness.
