Hi there, ChrisH,
Back in the 1970s, I enlisted my father's help to make a table top by assembling some teak boards, dowelling and glueing edge to edge. My father was an accomplished worker in wood and used a lot of Cascamite one-shot for his jobs (mostly soft woods but also some oak and mahogany).
Cascamite was, at that time, made by the Borden Chemical Company and, knowing that teak is an oily wood, I wrote to them asking their advice. They replied that the best adhesive for oily woods like teak was resorcinol resin based glues but they didn't make it! However, assembling while the joint faces were freshly planed ought to be OK but, to be sure, wipe them with carbon tetrachloride or washing-up liquid before glueing.
We followed their Plan B and that table top has lasted pretty well, one joint is showing a bit now but that edge has been against a radiator for some seven years. (We should have slotted the screw holes in the cross battens, drawing board style, but didn't!)
Ironically, a few weeks after we'd done the job I happened to be reading a copy of 'The Woodworker' and happened on an advertisement by the Borden Chemical Company announcing that they were now producing a new glue based on resorcinol resin! I never did get to try it!!
Best regards,
Swarf, Mostly!
