Another use for tint tubes

[Henedce]

When I need an acrylic disk I simply use a hole saw in the drill press. Take the centre drill bit out of the arbor and then you will get a nice round cut out with no hole in the centre. Tip: you need to measure the internal diameter of the hole saw, not the external! You MUST use a drill press if this is going to work and secure the acrylic tightly as there is no centre bit.

PS you will need to file the disc to tidy up the edges. This method isnt perfect!

Exact method I used . Was a slow process for 127 of them but it works

I wonder if an acrylic supplier out of china could provide them..

Especially if there was enough interest to get a sizeable order together?

A coro / sign shop could also machine white coro for a perfect fit as well.
Doing that many disks, might be worth the few $$ to have someone do it for you.
Great idea routing the board.

Is the effect in the video generated by nutcracker or some other method?
