Jamie McGannon Posted May 1, 2013 Report Share Posted May 1, 2013 I'm building a closet built in for my sons bedroom and need your opinion, which is a better shelf material? The shelf measures 28"x28" and will be attached to slides to pull out and needs to be measure 1" thick to accommodate the slides. 1. Does anyone know if Baltic birch multiply is available 1" thick? 2. Would 1" thick MDF serve as a better shelf material? The shelf will hold 30-50lbs.

wdwerker Posted May 1, 2013 Report Share Posted May 1, 2013 At 28 by 28 you could use 1/2" or 5/8 " thick Baltic and double up the edges with 1 1/2" wide strips. That way it is thick enough for the slides and doesn't weigh a lot either. I like the 5/8 better, it is usually just a bit more than 9/16 thick so doubled it is 1 3/16" thick. It is plenty strong and stiff for a shelf that size. A little yellow glue and either clamps or a few short nails and there you go. I bought a few sheets of 5/8 today for $31 a sheet but anything under $ 40 is reasonable if you aren't buying quantity. The 1/2 is cheaper but it measures a bit under 1/2" so doubled it is under 15/16" and it is not as stiff as I like. 1 Quote Link to comment Share on other sites More sharing options...
chopnhack Posted May 1, 2013 Report Share Posted May 1, 2013 Agreed with wdwerker. Plenty strong as he advised, or edge band the plywood with some solid material to give you an anchoring point for your slides. MDF would not be suitable as it would sag over time, would be very heavy and as usual, a child will inadvertently climb on the shelf to reach something higher. MDF may split under this type of point load whereas ply probably will not. Quote Link to comment Share on other sites More sharing options...
Jamie McGannon Posted May 1, 2013 Author Report Share Posted May 1, 2013 Do you guys tongue and groove the solid material to ply? Quote Link to comment Share on other sites More sharing options...
chopnhack Posted May 1, 2013 Report Share Posted May 1, 2013 Do you guys tongue and groove the solid material to ply? You could. You could also use one of the fancy plywood bits. You could just glue it on. Quote Link to comment Share on other sites More sharing options...

wdwerker Posted May 1, 2013 Report Share Posted May 1, 2013 I like the look of the Baltic birch edge. I fill any small voids. On most of my drawers I just sand out the saw marks and ease the corners. A coat or 2 of Danish oil is an easy finish that is simple to repair / renew . To attach a solid wood edge you could biscuit, Domino, or use one of many different router bits. I have used a winged slot cutting bit to groove the ply and solid wood edge and made a snug fitting strip to glue them together. At the size you need a liberal coat of glue and a few pin nails will do the trick unless you really object to filling a few nail holes. I would double up the ply around the edge with the panel cut oversize then trim to size, thus yielding a flatter face to attach the solid wood to. Most Baltic has football shaped patches in at least one face. Not always a good ply for stain and finish applications. In a shelf or drawers they are rarely seen when in use.

Steve, what do you mean "double up the ply around the edges"? my plan was to glue up 2 pieces of 5/8, 30x30 then cut to size. Is this what you mean?

Tpt life Posted May 1, 2013 Report Share Posted May 1, 2013 You don't need to use that much ply although your method is simpler. You can rip 1.5 to 2 inch strips of ply to glue around the edges of a single layer of ply and keep the weight down. This way your edges are doubled. 1 Quote Link to comment Share on other sites More sharing options...
