I purchased the Unibond 800 as Aaron suggested. It does work, there are no wrinkles in the pear wood. That problem solved.
However, the first couple of times I used the Unibond my ambient temperature was hovering around 70*F and the veneers did not adhere. The instructions say no work should be done with the product under 70* and I thought I was within specs., but I guess not and decided to make sure.
I did several things. One, I trained heat lamps to warm up the substrate about 15 mins. to at least 80* using a thermometer; 2nd, I placed an electric blanket over the press (an old Sears and set it on high which brought the bag to about 80*); 3rd, I placed the mixed glue in a 90* bath of hot water after mixing and let it sit a couple of mins. I used a black foam roller and placed a thin coating on the surface of the substrate, waited a couple of minutes with the heat lamps on and then installed a second coat making sure the edges were well coated.
I know from the instructions that I had 15 mins. maximum to install in press. The time the glue was in the water bath, applied to the substrate, and the veneer installed in the press was about ten minutes. I pressed for 5 hrs. and the edges were tight. I pressed a second time for 3 hrs. and the edges were iffy. So now I plan to press for minimum for 5 hrs.
I want to thank you all for your help and advice. My client is anxious about the time but I explained the process and stated that I couldn't cut corners and still offer a guarantee. Many thanks again to Aaron, Don and Darryl.
