Smile dip bowl...

The Strathfield Mens Shed has acquired a small CNC laser cutter and the operator has made a template out of 5mm acrylic that he wants me to trial.

A couple of pictures are attached.

This is very much still R&D at this stage to see what works and what needs to be changed..

The timber is just a round piece of pine from a failed Lazy Susan

I feel that the template has to be made from 10mm mdf or similar so that the bearing guided dish cutter can be used.

It looks a tad small using a template guide...

I agree, 6mm is just too thin. N

James is this to be a bowl/tray? or a cut out part for some other piece of furniture?

OOps, I didn't read the title very well. How does the router slide on the acrylic with the paper still attached?

That's a shame James , as my 80watt laser does what I would consider perfect cuts with 6mm plexi , and although it will cut 12mm , it's not great

My tube is giving me issues so maybe I should go to a 120 watt next time , but that involves a new PS and in my case a larger water cooler

I don’t always insulate , but when I do .
Ok ,I never insulate

Hi Herb,

Using the router skis made for me by Harry, the router base does not actually touch the acrylic.
It rides about 3mm above the acrylic and the guide bush rides against the side of the template.

On each side, you lose the amount of the offset and you can see that lip in the pictures.

A round cutout will be made on the top right corner for the dip and the larger bowl is for the crackers...
