I've got a Bosch Compound Mitre saw. One of the best purchases I've made, but I was still getting blowout in many cases.
I was looking through one of my Dad's old Fine Woodworking mags once, and the author suggested cutting a scrap at an appropriate angle then clamping that BEHIND the piece you're actually cutting on the saw, so that the cut is exactly lined up with the edge of the scrap.
Presto no more blowout, regardless of the wood, angle, or grain pattern.
And you save your sawing arm in the process!
Now, you realize your going to HAVE to move the coin slots somewhere up hi and put some sort of rube goldberg contraption on the inside, where the coin falls through a maze of tubes, gizmos, ferris wheels, flashing LEDS, etc, just like what happens on the inside of those opaque cabs (it's all magic you know
)
Here's an example (arcade related no less!)
