View Full Version : Gluing over BLO
12-04-2007, 11:10 PM
I've been busy building a workbench. Nothing fancy, basic slab out of SYP and a simple frame. It's now vise time, and I have a small problem.
I prematurely finished the slab with a couple of coats of boiled linseed oil (on both sides), and I need to glue on a small piece to the bottom for the vise jaw. I can do some light sanding of course, but the oil probably soaked in pretty deep. Any issue with glue strength here? Should I use an epoxy instead?

Oooo, stanketh! Ding dang, that's gonna' be a rough one. You MAY get a decent bond with epoxy, but I think I'd try the polyuurethane glue instead. I also think I'd find some way to use metal mechanical fasteners.

I don't know, man, BLO and other oil really does not penetrate long grain much at all, contrary to what the merchants of some of those "penetrating wood protecting yada yada" finishes claim. Some woods will drink up gallons of liquid through the end grain, but penetration of long grain is pretty much a myth. I think a decent sanding will get you below the surface that the BLO has penetrated.

You might try a good wet solvent wipe preferably with acetone, or lacquer thinner. Make sure that has dried before attempting to glue.

Thanks everyone for the great advice. I think I'll try all three suggestions: a little sanding, a little solvent, and a poly glue. I dislike the foaming, but in this case it's not too difficult to clean up.
And if it breaks off, I'll put some really really big screws in :-)

I'd agree with this... a few swipes with my plane got rid of all of the finish on my walnut bench... I decided to make it longer after doing a test finish on one end. two coats of BLO, two coats of "tung oil finish".

That's what I was thinkin, too, Mike.
A high flash solvent will usually draw out and dry up oily surfaces.
Especially Laq thinner. Acetone too, but I'm more prone to Laq thinner.
And some brads... just till the glue drys. }> :7 LOL
