I have sheets of wavy mahogany veneer that I want to use. What is the best way of removing this undulation so that I can use this veneer? Do I wet the sheet, clamp it between two flat boards, then when dry, glue it to a backing board? Any comments would be greatly appreciated>

There are products called veneer softeners - I have one that I bought from Carba-Tec, Rivergum brand https://www.carbatec.com.au/embellishment/veneering-tools/veneer-softener . It works well and comes with instructions. From memory I sprayed the veneer (a very wavy fiddleback Blackwood) liberally with the softener then glued it on it in a vacuum veneer press - with a low-foam polyurethane adhesive called Purbond (from Bote-Cote). I may have flattened it out in the press first, but I'm sure there are instructions with the softener.

I would lightly spray with water each side . The less water you can get away with the better. It quickly becomes softer. Then place a few sheets of newspaper on a larger board, place veneer then a few more sheets of paper and clamp or weight another board on top. Change out the damp paper every day for a few days with dry stuff or for as long as you think is right . This is how its pretty much described in veneering books .

I used a mix of glycerine, water and a little Metho. Can't remember exact quantities, but was about 10-15% glecerine to water and just a little Metho. Clamped between to sheets of formply(that's what I had on hand) with butchers paper. Worked a treat. Just keep it clamped up until needed. I think I changed the paper out once, but it was summer and bloody hot.

I just used titebond 3 for glue up. And if it goes pear shaped, I discovered if you go over it with a hot iron over a cloth then re clamp you can get out any bubbles that didn't glue down properly. The veneer I used was about 40 years old and in pretty bad shape.

That sounds like a successful plan that I will use on a trial piece. Ive just experimented with a piece of veneer glued with Titebond 3 in a vacuum press, successful. Now I'll try a very crinkled piece of veneer using your method and see what happens.
