Scarf Joints in Plywood

I used my radial arm saw (craftsman). I was able to turn and tilt to
the desired angle.
Then set up a fence to just run my plywood through. The down side is, I
haven't used my saw for sawing in over a year because I don't want to
have to set it up again. I've even considered buying another smaller,
saw just for the scarfing set up.
