Someone here mentioned using a transfer punch when making a center support. Since my eyes aren't getting any younger and I make my own supports does anyone know where I might purchase a 5/16 transfer punch???
You can usually get the entire set for $10-12.00 from places like Enco and Harbor Freight. That is a fractional set and should cover most anything you might need. Me, I got it bad, I bought the fractional, letter, number, and fractional up to 1". I do every now and then find need for some of the huge ones that come in the 1/2"-1" kit. Once you buy a set though you will find plenty of uses for them especially when it comes to lining things up.
