Shelf ledgers... how to size?
Hi all. I'm struggling to determine how thick/wide ledgers need to be. Everyone seems to use 1x2 furring strips or something similar, but I'd like to keep mine smaller and less visible if I can.
My thinking is that since I'm using 3/4" ply (true) my ledgers shouldn't have to be very big... just enough to hold the nail and support the shelf. On that note, couple of questions:
1) How do you determine ledger size? Is there a rule?
2) With 3/4" ply supported on 3 sides (and front braced with a poplar 1x2), are 3/4" x 3/4" ledgers enough?
3) Is there any reason not to use the leavings from my 4x8 plywood sheets? Saving material is always nice, and I have lots of 3/4" strips I can rip to 3/4 (square).
4) Are 16g 2.25" or 2.5" nails into the joists adequate for support?
Thanks in advance for any help.
