While the MDF snowman worked out nicely, and it looked ok painted up, I wanted to get back to trying my hand at making some models from acrylic.
Given that Christmas is rapidly approaching, I thought I’d tackle the snowman again, and see just how well the CNC, along with a new set of router bits specifically for plastic from toolstoday.com would work out.
Just an aside for a second. I have just gotten an iPad Pro, and while writing the article, have used one of the pro’s features of being able to run a second program simultaneously, and on screen at the same time. Awesome feature!
I still have some processes to work out to make things run smoother on the CNC process of working with acrylic, but for the most part it went very well. Acrylic is pretty flexible when it gets thin, even worse than MDF it seems, if that is even possible. So I found myself supervising the whole job while it was machining. I was using an upcut bit, and perhaps that also has a lot to do with it. While chip clearance is important (especially with a material that can melt), lifting the piece is not the best way of ensuring it is stable. I still don’t have revolution speed control, so am still running the bits slower than I would like, and again that is probably a real factor.
Still, the result is a great snowman. Looks awesome (especially with Kara Rasmanis wielding her camera)
