Tim - I gotta smile - you just very simply and accurately described the glues and techniques that I "try" to follow. The one exception is the pre-gluing of the rib edges with wood glue. I use the technique on the end of stock but hadn't thought about using it on the rib edges too. Great input.

I use 2 hollow core doors. One is used as a base for supporting 2 1/2 acoustical ceiling tiles for pinning. The tiles are framed with cheap household molding pieces to keep them tight together. The other is used to support a large mirror (glass surface) for cutting covering & assembling multi-piece covering panels. Ultracote's adhesive releases cleanly from the glass surface after it cools.

I bought a magnetic board and appliances at our local auction (back in Feb). It looks like the original that Great Planes "adopted" and sells replacement parts. Should prove to be interesting.
