To build a poster magnet board you will need the following:Parts and Materials
- 1, poster frame with an acrylic face (24 x 36 in.)
- 1, cool poster/picture (24 x 36 in.)
- 1, flat sheet of galvanized tin (24 x 36 in., 24 - 30 gauge )
- neodymium magnets (between 1 - 2 lbs pull force)
- 1, roll masking tape (1" wide)
About The Frame:
- leather work gloves to handle tin
- hot glue or white glue
- tin snips (unneeded if tin is correct size)
- tape measure (unneeded if tin is correct size)
- straight edge (unneeded if tin is correct size)
- marking pen (unneeded if tin is correct size)
- hammer and block of wood (not pictured, unneeded if tin is correct size)
You want an acrylic face, not glass. Glass can break and is too smooth for these magnets to stick reliably. It should have a rigid backing. Hardboard or cardboard are typical. It should have tabs, staples, or a similar mechanism that bends to put pressure on the backing. The hanger should be attached to the backing, not the frame. Wood and metal frames are not necessary. We use inexpensive, plastic frames.About The Tin Sheet:
Magnets will not stick to aluminum, copper, brass, etc. The sheet can be smaller than the frame. 30 gauge sheet can usually be found at building supply stores in sections that carry heat , ventilation, and air conditioning ducting. Otherwise, suppliers of sheet metal in your industrial districts will usually cut you a piece to size. Bring your gloves to handle it.
