I am preparing to construct the built-in unit described in FWW – Built-in Basics by Tony O’Malley. The assembly is based on the splines and biscuit joinery. Because I have access to a supply of inexpensive seconds of ½ “ cherry plywood I am planning on using this material. However there are a few issues I need to resolve.
1) Can I expect a lot of problems in biscuit joining the carcasses using the ½ “ material. There is not a lot of stock thickness to deal with and I will need a biscuit jointer that make accurate slots in the thin material. Right now I am preparing to buy the Porter Cable 557 or a high end Makita. Should I expect these to work well in the thinner stock?
2) I plan to laminate the plywood to get increased thickness and strength for the shelves and add plywood strip spacers in joining the carcases. Should I use contact cement or wood glue in laminating the plywood for the shelves.
3) As one of the ends of the unit will be exposed I was planning to increase the thickness for the trim by using plywood strip spacers and glue/nail a second sheet that can be scribed to the wall. Is this sandwich construction on the end likely to warp or bow?
(Because I am using thinner material I am going to use the ½” material for the backs of the carcasses to get better strength)
Comments would be appreciated especially on the biscuit joiner. It will not take to many ruined sheets of plywood to pay for one that helps make the job go right.
