Routing the base of the Do-Nothing Machine

 

Picture 1 – Setting the router depth.

I managed to route the grooves for the do-nothing machine this weekend. This post is the step-by-step description of the process; including the “stupid” things I did. We have all been told experience is the best teacher, but as my father used to say: “It is

Hatching and Hatching “Gotchas” LibreCAD Tutorial part 2

In the book “Zen and the Art of Motorcycle Maintenance” the author talks about “gumption traps” … things that take the wind out of your sails and makes you want to give up. I would add to his list software that does not act the way you expect it to act. That means something that

Hatching and Hatching “Gotchas” LibreCAD Tutorial part 1

I just posted another tutorial about LibreCAD in my YouTube Channel. This one is about hatching. Hatching is similar to a fill function in most drawing programs, except hatching fills a surface with a pattern. LibreCAD comes with a library of patterns.

Post 62B — A correction to a previous post and video.

Oops… I messed up. In my tutorial No, 8 and post 61A about the LibreCAD select functions, I said the following:

A select (or deselect) window drawn from left to right would only select items completely enclosed. This is incorrect. If the window is drawn from top to bottom it will only select items completely

Episode 62 – Finite minds – Infinite details

Not often the correct answer!

To understand complicated machines and processes, we often have to break those down into sub-processes and components. However, since each component must work with the whole, we have to know how it fits with the whole. What is the function it is trying to do? What inputs does it

My Version of the clock-face.

I partially complete the clock face by drawing each of the Roman Numerals. I did not drawing the X characters. I will leave that for you to complete. If anyone does attempt it, I am interested in how you do it. Please send me your dxf file or a

Wim’s Clockface

Very often you do not know all of the information to be able to create something “exactly right”, so you take your best guesses and figure out ways to get better when the time comes. That is somewhat the case in this video. I had a gentleman, Wim, contact me via

Post 61A – LibreCAD tutorial 8 – Polygons and Select functions.

I just posted a new tutorial about LibreCAD. This tutorial is about several line functions we have not talked about before.

Polylines (These are line segments all grouped together.) Rectangle Polygons (center and corner or 2 corner versions) Bisector (dividing an angle into equal parts)

You will notice a few “gotchas” or features about those

Episode 61 Understanding the Ellipsograph

The standard equation for an ellipse.

Being a nerd is a high price to pay. A simple little toy has lead me into lots of charts and graphs and math and … it goes on and on. There is always more to discover, even about simple things. I want to point out one thing
