HB2 Lives

This is the first package of materials for the construction of the HB2 CNC router project. There is a full description of this first shipment in my The Hobbyist’s Machine Shop web site.

Look in the Site Tools drop down menu and select “What’s New”. Scroll down in the pop up window until you see the “HB2 Construction” link.

This is the first of what will likely be many articles on the construction of the HB2.

It is finally out of the dream and scheme stage and into the build phase.

Update 7/6: Drill Patterns all cut and trimmed.

Small But Mighty

If you read the special Article I wrote called Funding HB2 you know I am struggling with the cost of building a large first class CNC router, especially the long term consequences of a large investment. Like many hobbyist, I become very zealous in studying all the details before I leap. Actually that is a worthy trait for the hobbyist that has if nothing else, a lot of time.

What I decided is HB2 is not a machine for business. I discuss that option in the other article. HB1 is definitely too small for the work I want to attempt such as… Continue reading

This drives me to thinking about why I built the machine in the first place.

I was influenced by John Kleinbauer’s web site on building low cost CNC machines. I ordered and built his controller… Continue reading

Projects Not Quite on the Bench

I am getting enthused with my many design sketches for the next CNC machine. It has been hard for me to scale back on size with my design schemes. It all relates to my own advice that I must have a product I want to produce and size the machine to accomplish the task. What I really must do is to keep it within a size constraint that will fit into my residential shop area. It still looks like ~ 25 x 25 or so working area with larger overall dimensions.

There have been lessons learned on the first machine… Continue reading
