For woodworkers who like to spell things out — in signs, that is — the new Interlock Signmaker’s Template from Rockler Woodworking and Hardware makes things a bit easier. It comes as a series of interchangeable puzzle pieces, in kits featuring both letters and numbers. The pieces snap together and, after securing them with masking tape, you’re ready to rout — you can even arrange them in stacks, circles or other shapes. Letter kits of Signmaker’s Templates contain 40 templates — with duplicates of common letters and three spacers — while each numbers kit contains two sets of numerals 0 to 9 plus nine commonly used symbols. As of 2010, both letter and number kits come in 2-1⁄4″ and 4″ sizes, with the 2-1⁄4″ sets selling for $19.99 and the 4″ sets for $29.99 as of 2010.
