I thought there must be variation in the spindle-to-wasteboard distance on this X-Carve CNC router. At least 60 thousandths of an inch, it turns out! Don't take flatness or consistent distance for granted on something like this.

The radial symmetry in this part of my drawing-in-progress is very satisfying to me. #solidworks #sheetmetaldesign #draftingitoldschool

Join me at Hacklab North Boynton for another six sessions of my Intro to 3D Design course, great for anyone interested in 3d printing or digital fabrication. We'll use the free browser-based CAD software Onshape. See you there!

Who wants to join me in THE FUTURE? I'll be teaching an introductory CAD course at Hacklab North Boynton on Monday nights from 7-9. The price is $25 per session or $140 for all six. You'll learn to design your own parts suitable for 3d printing, machining, or any other process. All you need is a laptop and a mouse.

First session is THIS MONDAY, January 18th. We'll meet again on the 25th and on February 1st, 8th, 22nd, and 29th.

See you there!

Here's a plywood mount I made for my bench grinder, intended to be portable so I can take it to my outdoor workbench when I want to make a big mess. Dovetails I cut partially by hand, partially by bandsaw. The handholds I routed using a lasercut acrylic template and a top-bearing trim bit. All edges got routed with a 1/4" round-over bit as well.
