For frosting acrylic, you'll want to wetsand the whole way. This will eliminate swirl and scratch marks.

Start with 120 grit, then 220, then 300 or 400, and you can go higher if you wish. However,...

Yes, CNC controlled lasers work best to cut acrylic as when your piece is done, it requires virtually no finishing work. Not only do they have the accuracy of a CNC and a laser, but the laser's...

That would be a bit tricky to do, but achievable. Yes, you would have to "rough it up" a bit before you sprayed it. They do indeed make transparent paints, but I have only seen them for airbrushes,...

Hehe. Just build you own. My router is costing less than $400 to build, everything included. Add a laser to that and its still probably less than $1200.

Hehe... yup. As soon as my machine is done, it will be used to cut and drill higher precision parts that will be used to replace the hand made ones in the machine. Eventually, I plan on building a...

I am currently building a CNC machine - it will be a CNC router. Eventually, I will use to it to cut out a new CNC machine for myself: this one will use a laser, probably CO2.

Hey guys,

More tips and what-not. The edge sraping in your log was great, thats what I forgot to mention. Really, any type of metal with a nice edge will work, but pros use a small rectangular...

Sounds good, but we NEVER sanded the edges when I polished them... then again, that was a professional torch. :D :D

Tell me how it goes, I've never tried using a heat gun for polishing.

Hey,

I can only give you a few tips. I assume you saw the flame polishing technique in my work log, right? Just remember to not get too close, and ALWAYS keep the torch moving. A butane torch...

Glad I could help.

Hey,

Magic marker will leave marker lines and look like crap. Paint is very hard to get to stick to acrylic, especially if you can't rough up the surface, since you are trying to mantain...

My work log shows a bit of cutting, bending, and flame polishing (watch the video). A guide is coming to my site,...
