Lumpy plywood
I have been restoring a plywood boat approx 20yrs old & have noticed a
ridge in one sheet of ply running accross the sheet in a uniform manner. I have removed paint down to the wood & everything seems OK, no sign of damp or delaminating. Is this quite normal for ply to do this or could there be an underlying fault? If so is it best to just ignore it as it just seems cosmetic to me. By the way its nowhere near the end of the sheet or any other obvious weak point. Thanx, Graeme |

Thanx, Graeme You shuld not vorry, ------- this one you can se, acturly nomatter ply or wood, a boatbuilder know af a few "repairs" that made it possible to use a plank making it even better than one with no foults from the start, and if you check how you fit veners together , you will know what your "foult" is. With tradisional wood, you drill out knots and repair cracks, with Ply you shuld be glad that this efford is done, producing an even better enginered wood product, it's just a prove about quality you notised. ----------- Check how you make two pieces of veneer fit edge by edge.

Lumpy plywood
As you know, plywood is a "layered up" substrate that is produced under tons
of pressure utilizing a variety of glue and temps for various applications. Many times I have taken back to the shop a sheet of Plywood with just such a laminating flaw in it. Didn't do anything negative to my project, just ticks me off cause, I don't see it in the dim lights of the Lumberyard. From my experience , I'd say, it's a crease that got caught in the press and sneaked passed Q.C. "Graaeme" wrote in message om...
