I'm looking at doing my first veneered project - a table top about 15X40. I want to use 1/16 veneer (likely black walnut) so I can break the edges, give final hand smoother passes, etc. but am not quite ready to shop saw my own.
At A&M Wood (just down the road), 1/16 is $4.40/sq ft, 1/32 is $2.25 and "thin" is $1.50. I suspect the cheaper is peeled vs. sawn/sanded. I'm wondering if I'd have any problems with cupping of the substrate (3/4 MDF) if I used 1/16 on the top surface and thin on the bottom surface? I will likely use PVA glue.
I recall being taught 1/16 is thin enough so differential expansion is not an issue. So it's the moisture from the glue that causes the force leading to cupping?
Thanks
