Yup, The question of hold down is important.
Since this jig was for a relatively short run, and since the boards I cut were longer than 8" my hold down fingers were safely away from the blade.
If You are going to do a lot of cuts, short cuts or keep the jig for awhile upgrading the hold down would be important.
I have not decided whether to keep this jig or just take it apart and throw the parts back in the scrap pile. If I keep it I will make the angle adjustable and add hold down capability.Often in error - Never in doubt

In my opinion the jig that Shoottx suggests can be made safer.
The workpiece is pushed forward by the lip at the bottom.
The scary part is either letting the workpiece go with no hold down pressure or using your hand within a couple of inches of the blade.
Here's how you make it safer:
Put a piece of rectangular plywood under that jig, attached to the bottom of the arms. It should be as long as the jig and a tad wider than the fence to blade width.
One edge should be against the fence and flush with the right arm.
When you cut, the plywood will be trimmed at the saw blade of course. But the dangerous part of holding the workpiece as you slide it within inches of the blade can then be accomplished with a pair of hold down clamps mounted to the arm of the jig adjacent to the workpiece. You'll have to raise the blade the extra height of the thickness of the plywood.
Excellent point I was going to use hold downs as I value my fingers and would rather not have to recut due to movement.Jon

If your only tool is a hammer, you tend to treat all problems as if they were nails.
