Hey Jon, When building forms from that LVL material, you'll have much better luck keeping it straight using full 1.75" thickness rather than sanding it down to 1.5" . the last one i built i just used a router on each side along the edge in a few spots to get it to 1.5" to center the lams.
Edge banding the cut out is good too, as well as sealing it well. i use a Deft brush on lacquer, or Shellac. I buy it by the gallon pretty cheap and use it a lot for sealing all kinds of things.... Food for thought. Kirk
Thanks, I usually run my forms 1.75 anyway, as I've always run 1.75 glass. I just like having plenty of material to work with if needed.
I was surprised out how reasonable it was. 6 footer was only $54. I would have spent alot more than that for cabinet grade ply.
