Hardboard Spray Stencils

Post by hanselcj » Thu Apr 23, 2015 12:55 am

Someone else on the forum mentioned using metal flashing to create spray paint stencils. I liked the idea and was trying to cut out card stock with my swivel cutter attachment. Sadly, it isn't a very reliable method. Instead I changed course and went with hardboard (sometimes called masonite). It is a pretty easy material to mill, but left a small amount of fuzz at some edges. A knife removed most of it. Here is the finished product:

It is my rendition of a varroa mite. They infest honey bee colonies and are horrible horrible creatures. I have a beehive in my backyard and wanted them to have some sweet decor.

I thought I was being clever by cutting up the NO cross out thing, but apparently the image isn't symmetric. I must have biased the slash up or down a bit without realizing it. Oh well, you live and learn

Both jobs were done with a up-cut spiral 1/8" bit. The material is about an 1/8" thick. I used 30ipm, and set it to do 1/16" per pass. I could probably get a lot more aggressive and be fine. So yeah, try hardboard for you stencils, but don't follow my lead on screwing up the design.

That appeared to work well. You might also try 1/8" plywood, it might not have as much fuzz.

That's a really inexpensive straight bit, but for fuzz and chip out a spiral bit is nice. I guess I'm being too picky.

Those are good bits, I have some of them. I was looking for the bottom surface to be clean. Maybe I will try a straight flute next time.
