Need advice :cutting a 2'' sphere intwo

[laserfred]

Heu guys,

I have 2" acrylic spheres that I need to cut in 2 halves to convert them in cabochons(will become dots on I's). I bought balls because they were 1/4 the price of cabochons, plus I get 2.... only thing is I have to cut them nicely.

I have a sawbench with a decent blade, but no bandsaw. I have a co2 laser I could use for making a jig too....

Mind boggling!

Ok I found a way!

Anyone interested to know, here is the little jig I made to hold the ball. I put some double-sided tape on two of the tabs so the ball wouldn't start spinning. The rest was easy. Perfectly sliced in the center...

Yeah, this is the fun part the client doesn't know about!

...and do you hold that ball from spinning with your fingers...

I just did something similar cutting an 8' long piece of 3" diameter pvc pipe in half....

What type of blade was used?

damn that's cool...

I want one!!

(given the odds, half my future is bad news... I want a crystal ball to gaze into, where only the good news lives... shoot... which half should I get?)

I was gonna suggest a Karate Chop but it looks like you've figured it out.

I use a thin kerf, non-ferrous metal saw blade. Good for plastics and aluminum.
