MIT TechTV – Home. Videos - machining - Academy of Lagado. Videos for Learning Home Machining - Free There are hundreds and hundreds of videos available on the web (and for purchase) which can help you to learn basic machining techniques.
On this page I provide links to a selected list of these videos as an aid to to those people who are just getting started in home machining, with the goal of providing the equivalent of a video training class in basic machining methods for the lathe, mill, and other equipment. Have a comment, suggestion or correction?
Please comment here. Note: If you are leaving a comment, please keep in mind that the purpose of this page is not to include every video on machining, but rather to serve as an overview and introduction to home machining.

My Mill - Academy of Lagado. My Mill - A LittleMachineShop Model 3900 HiTorque Mini Mill [April 9, 2013][April 13, 2013][April 22, 2013] I purchased my mill used in 2012.
As purchased, the mill had DROs (digital read-outs) already installed for the X,Y, and Z axes, as well as a spindle stop. The photo to the left shows the mill (with way covers in place) in my small basement workshop. The purchase also included a sturdy metal stand on casters, a small mill vise, a set of collets, the tools that come with the mill when purchased new, and a LED lamp (which I have since replaced with two LED lamps). Below are two more views of the mill. The photos below show the nameplate for the mill, with model number and specifications.

How to Make a Three Axis CNC Machine (Cheaply and Easily) A salute to those who have laboured through to this point (and to demonstrate that it is reproducable) Here are some pictures of other peoples machines.
Photo 1 - Chris and his friend put together this unit; laser cutting the parts out of half inch acrylic. Not only does it look super it must weigh a ton. But kudos, anyone who's worked with acrylic knows laser cutting it is great but it is a very very unfriendly material to drill and there is a lot of side drilling in this design. Good job guys, check out more details (and photos including some testing with circuit boards) on Chris's blog rainbowlazer.com. I particularly like his work with making 3-d objects out of 2d cuts (here) . Photo 2 - Sam McCaskill has finished his desktop CNC machine and it's looking really really nice. Photo 3 - Angry Monk's - With MDF pieces cut on a laser cutter and drive converted from toothed belts to threaded rod. CNC Projects. 4th Axis Ideas. I decided to stay with my 495 holding torque stepper motor and timing pulley ratio and add the Taig lathe chuck to fit the 3/4" ER32 collet.
This way I can remove the Chuck and use the ER32 collets. The pictures will show the Newer 4th axis setup. The ER32 fit the 3/4" ID bearings, just a nice slip fit. Added a spring loaded block to clamp the ER32 for the wrench. Also added a chip/swarf plastic cover. Motor fits in a milled pocket Small Ball Bearing added for Backlash takeout. May add another bearing below. I seen this gearbox used a while back. 4th Axis with 495 oz-in holding power stepper motor, The Taig Lathe and Milling Machine.
