Can someone tell me what R16.14" means? I've never really done angle cuts at all and was hoping someone here could enlighten me a little bit.
-
R usually refers to a radius. That seems quite large though for a cab.
link?

You have to be careful with the Jakobud plans, FYI. They aren't exactly right.
-
That's what I figured....I was looking at a good one or two to build...figured I could use those but I have no idea how to draw a radius like that on the plywood.

OBTW, I was looking at the MS pacman cabinet

Pencil, nail, & a piece of string

I second this. Unless you have some background in drafting, or have the help of software, they kinda come out funny.

What do you mean pencil, nail, piece of string?
-
Say you need a 12" radius marked out. Take a nail, tap it in at the center of the arc, leave some of the nail sticking up. Tie a piece of string to the nail. Measure out 12" on the string, tie a pencil to the string, pull the string tight, and you can draw a curve that way.
You could also do the same thing with a ruler or yardstick if you don't mind poking holes in it.

A beam compass is a good thing to have. A string and a nail will certainly work, but I've always had trouble getting an exact radius after trying to tie the pencil to the nail. With a beam compass I'm able to get exactly what I want... down to my ability to read a scale.
My cab had several large curves, R7 7/8", R10", and R40 1/4"... layout was very easy with the beam compass.
