I am facing having to remake a tabletop because the veneer has "peeled up" at the joints. This is quartersawn mahogany, shop sawn to 1/8—3/32. All the veneer seams have failed. I did some distructive testing (I took a chisel and split out a couple of chunks of veneer on the bottom of the table, both top and bottom were veneered and both failed). It appears that the mdf core is where the failure occurred, not the glue line. I used Unibond 800.
I'm going to redo the table top with commercial veneer that will be a lot thinner. However, I'm wondering how to avoid the problem in the future since I like the ability to make my own veneer and I like the thickness that one can get with them.
Will a crossband layer of veneer between the mdf and the finished layer be advised? It seems to me that this sub-base will give a much tougher surface that will withstand the subsequent force of a thick veneer that wants to behave like a regular board. If this is the case, should one do a crossband layer in all applications? I'm looking for the "best" product, not the quickest or least costly. I'd appreciate any thoughts and/or help.
