Overhead Trolley Helps Clear the Air over CNC Router

Posted on by

[Frank Howarth] has a shop most woodworkers would kill for, stuffed with enough tools to equip multiple hackspaces — four radial-arm saws alone! But while the CNC router in the middle of the shop, large enough to work on an entire sheet of plywood, is a gem of a machine, it was proving to be a dusty nightmare. [Frank]’s solution was as unique as his workspace — this swiveling overhead dust extraction system.

The two-part video below shows how he dealt with the dual problems of collection and removal. The former was a fairly simple brush-bristle shroud of the type …read more

Clear the Air Around Your CNC Router with a Custom Dust Shroud

Posted on by

Using a CNC router is a dusty business if your material of choice is wood. Sure, you can keep things tidy by chasing the cutter around the table with a shop vac, but that sort of takes the fun out of having a machine that can make cuts without you. The big boy machines all have integrated dust collection, and now you can too with this 3D-printed CNC router dust shoe.

Designed specifically for the X-Carve with a DeWalt 611 router, [Mark Edstrom]’s brush is a simple design that’s almost entirely 3D printed. The shroud encloses the router body and …read more

Machine Tool Build is Anything But Boring

Posted on by

“So just like every other great story in history, ours is going to start at the lathe.” Truer words were never spoken, and thus begins the saga of turning a bar of chrome-moly steel into a shop-built boring head.

You may have a few questions regarding [ThisOldTony]’s effort. First, unless you’re familiar with machine tooling, you may wonder what exactly a boring head is. The video below makes it plain, but the short answer is that it’s a tool to make holes. A boring head spins a boring bar with a cutting tool, and the head can be offset to spin …read more

CNC Drag Knife Upgrade with Off-the-Shelf Blades

Posted on by

Drag Knives seem to be the overshadowed awkward kid on the playground of CNC equipment, but they have a definitive niche making stencils, vinyl stickers, and paper cuts. Unfortunately, the drag knife blades for CNC routers are pricey — over $100 for a single blade. [Brian] at the Grunblau Design Studio took the price point as a challenge to build his own end-effector. A few iterations later, he’s created his very own drag knife blade tool that accepts replaceable steel blades for cutting.

From constraint-driven concept, to a 3D printed proof-of-concept, to a fully machined aluminum prototype, [Brian’s] efforts hit …read more
