Can finishes reduce glue joint strength?

Possibly a bit of an odd question but I am laminating a stack of probably fifteen pieces of veneer(Titebond 3) and it will be sanded to show the layers of veneer. I have done this before and have used wax on the surface and they have held up fine, this time I am thinking of using Danish Oil, would there be any chance that the penetrating nature of the oil may weaken my bond between the layers of veneer?

The wings on the Owl would probably best show what I am doing-

Cheers.

Once the glue bond has cured the applied oil finish will have no effect. However T3 may exhibit glue creep which will be felt across the laminations; perhaps an epoxy or polyurethane glue may be more suitable? Danish oil won’t affect these either.

As said above and they are cool

Thanks gents, great to know but I should have asked about the glue before starting.
I used just a bog stock PVA on the owl and there's no creep, would the Titenond be worse?

Hi Ubernoob,

My experience is that Sellys Aquadhere, Titebond 2, Titebond 3 and Titebond Extend all have a degree of flexibility afiter they dry and so have the potential for creep when veneering a curve or a larger panel. If you want a rigid bond something like Cascamite (urea formaldehyde) or epoxy would be the go. Possibly also hide glue, although it’s many years since I used that.

All that said, for pieces the size you are making I very much doubt there would ever be an issue with any of these glues. The creep issue is more significant on larger items.

I’ve used all of these glues on boxes at one time or another, and finished the various boxes with shellac, tung oil, danish oil (of various types), polyurethane, varnish, linseed oil, Tru-Oil and Osmo hardwax oil. Never had any problems with loosening the veneers or main joints.

Hope this helps. Your work is simply sensational, by the way!

Brian

Thanks for the info homey and for the kind words :)
The owl may appear to be a bit of an odd shape but it is a money box that can accommodate a lot of coins, you pop a coin in the top and rotate the beak to drop it in.

I don't have many tools so I have to get creative with construction techniques, hahaha. The pieces for the owl were all hand cut and were a nightmare to flatten as they have a 4" hole in the middle of them, the plane is done with a holesaw and a bunch of sanding. They are in my Toy build thread, the current builds should be in there soon too.

Thanks again.

Thanks, like I said I lack tools and a decent bench so making things straight and square is not really something I can do so I make quirky stuff that makes my head hurt.

Had to go digging for pics, there seems to be no final pic of the movement but it is a circular wedge(pictured) with a steel counterweight to keep the beak in the right location, it was quite tricky to fit it all in and make it somewhat serviceable. The wings can move as they are dowelled and the coins come out through the base but it has four screws so kids can't open it :)

No, I don't believe that the oil finish will exclude the polymerized glue and delaminate your work.

Don't be too hard on yourself. That owl is a delight to look at and even better to learn of its function.
Screws will keep the kids out of it? Don't hold your breath in the face of stubborn determination.

As others have said, sensational work!
My fat fingers pressure the “want pictures” instead of “ thanks for the pictures” so ignore :-

Thanks gents, as people seem to like them I will compress my other thread in to one post-

Both my builds have been abandoned for the short term, the veneers I have do not contrast enough and just look like cheap ply when stacked so I will wait for Top Veneer to reopen and get some more suitable stuff.

Seems you gents were right about glue creep with PVA, the owl had quite pronounced bumps at most of the joins so it required a decent sanding before re waxing.
