I am going to cut a long story - short !
Am in the process of carrying out a major repair to fix fore-deck leaks.
Used a circular saw followed by a router to weed out out 48 fancy strips of white wood ( marfim , 5x5 mm)that were set with epoxy-glue in 5x5 mm recesses on the mahogany planking of the fore-deck. A back-breaking job.
BTW, these recesses are due to the overhang of adjacent plank-ends butting-up against each other.
Having used a 5/16 straight-cut bit on the router, the resulting rectangular grooves on the mahogany-planking now fit the new white-wood ( marfim )7 mm wide X 5mm deep strips perfectly.
To-morrow morning, I plan to seal the new grooves on the mahogany planking by swabbing with two-part epoxy diluted down with 5-8 % acetone (by volume). Similarly, seal the white-wood srips too. The epoxy is a slow-curing type (7 hours).
Some 5-6 hours after doing this, that is, just before the epoxy cures, plan to squirt Sikaflex (polyurethane) sealant into the grooves and then tap-in the new white-wood strips. Is this OK ?
Would welcome any suggestions and/or advice.
