Do you think any of your "warpage" is down to an impervious layer of glue on one face of the substrate and open to the "elephants" on the other face?

RogerM wrote:Great stuff Rob! What glue are you using for sticking down the veneer? If one of the TBs, do you find it difficult to work quickly enough without it "skinning" over?
Also what is your reason for placing the workpiece in the bag veneer down. I have always gone veneer side up so that I can see that nothing has moved, and it also gives me one last chance to run over the joins with a small roller just in case one or more of the veneers is not "flush" with its neighbour.

I suspect that if you're able to lay them veneer side up in your bag it probably isn't pulling enough suckage...dunno. The AirPress pump pulls an incredible vacuum and the needle on the gauge goes way past the max setting. If you've pulled the joints together 'righty tighty' with good quality masking tape and used veneer tape along the joint, the glue line will be (assuming the veneers have been shot in correctly) invisible - Rob

I wouldn't be surprised if the cupping were to do with heat and wet glue being applied to one side of the board and not to the other

In that case you're braver than wot I am Rog .......

If I'm following what Roger is saying, then I don't think he is. He seems to me to be using an over-sized substrate, and applying oversized veneers, and is simply cutting back afterwards.

Since when have you ever known me to approach things the "normal" way Rob?!

I guess you could support the overhangs on scraps from the substrate, maybe wrapped in plastic or tape.
Tell me, with this enormous clamping pressure is squeeze-out a big issue? I mean, if glue found its way out through a weakness in a veneer, or through a join, it could make something of a mess, couldn't it.

Just different coloured blocks of oak glued on to form the extra needed for the curve - RobRod wrote:Why the different woods at the corner?
