Right,

We've dealt with that by using double sided tape (especiallly if your running dry, we run wet so its hard) and by just making sure we have enough clearance between the holder and the material so when the piece does get flung it doesn't get caught.

For us the tradeoff of 5 hours vs 35 minutes is pretty huge. So we just have a kid sit there and make sure everything is g2g.

A vacuum table should hold it down well, but most routers don't have one.

Omax is interested in helping machine shops or schools which use their machines to make robot parts. They are looking into supplying teams and their sponsors with abrasive, maintenance help, etc. Please PM me with the information if you are interested.

Can any of you imagine what a nightmare that would be to do on a mill? I thought milling lightening holes into our chassis pieces was nightmarish...

And this is why CNC was created
If I only have a manual mill I usually use a 3/4inch drill bit to do my lighting.

I used a 3/8 inch 2-flute end mill. I started our with a 4-flute and learned that 4-flutes and aluminum don't mix it melted my piece. And the absence of WD-40 caused the aluminum to stick inside of the bit .
Also, it was manual.
