Turning your CNC into a Vinyl Cutter

This may seem like a no-brainer, but it’s actually pretty easy to modify your CNC machine to hold a vinyl cutter blade in order to do stencils or even cut out vinyl logos!

[Jouni] designed a holder for a standard Roland vinyl/sticker cutter blade (replacement with 5 blades is about $10 on eBay). It’s made to fit his specific CNC which uses a 65mm spindle, with a 49mm mounting ring — but the file could be easily modified to suit others.

Simply clamp your plastic or vinyl onto a flat piece of wood, and get stenciling! [Jouni’s] included his .STL file on his site in case anyone wants to try it out. While he’s designed it for 3D printing, you could probably CNC mill it as well — which would kinda make more sense…

Porsche-themed Mancave Clock: There is no Substitute

With an extra Porsche brake rotor lying about and a persistent friend to be silenced, [GordsGarage] decided to fabricate a one-of-a-kind man cave wall clock.

This was not to be a boring old hang-it-flat-on-the-wall design, though. The Porsche rotor is a composite design, with a steel hub and a ceramic disc weighing only a third of what an all-steel rotor weighs. That inspired [GordsGarage] to fabricate a wall bracket to hold the rotor and allow it to spin, showing off both sides. The business side has a brushed aluminum clock face with decals cut with a s vinyl-plotter and designed to look like a Porsche tachometer, while the reverse side has a nice custom badge for his friend’s shop. The build log shares some of the nice touches that went into the clock, like powder coated parts to mimic stock Porsche red brake calipers, and the secret [GordsGarage] logo.

It may not have been a clock for social good, but it’s a great design and a nice build that’s sure to brighten up his friend’s shop. And mancave warming presents are apparently a thing now, so we’ll be sure to keep our finger on the pulse of this social trend.

PCB stencils for $200


There’s some really cool stuff to find if you wander around a Michaels craft shop or Hobby Lobby long enough. Recently, [Ben] picked up a craft cutter – a small vinyl cutter-like device meant for scrapbooking and other crafty endevours. He’s using this machine to create solder paste stencils that are better than any laser cut stencil he’s used before.

Like a build we’ve seen before, [Ben] is using a desktop-sized vinyl cutter, the Sihouette Portrait,  with 4 mil Mylar. After converting the relevent layers of a Gerber file into .SVG files, [Ben] loaded up Robocut to cut very, very small holes in his solder stencil. The results are great; much better than a laser would cut Mylar, and good enough to apply paste to a few hundred boards at least.

While [Ben] is using his stencils to apply solder paste, we’re wondering if a similar process could be used to apply a UV-curing solder mask to home-fabbed boards. That would allow for some very professional-looking boards to be produced with a turnaround time of just a few hours.
