Milling Wax Adventure

The year is running out fast. I will soon have to say good-bye to 2011. This is the year (last Saturday actually) that I became 65 years old. Time enough for pondering that event, now to keep moving. Ha!

I did some machining of wax on the Taig CNC mill Saturday. I love machining wax (the hard blue kind). The wax is not good for creating real finished useful items but it makes excellent models for making molds and doing casting.

I spent the morning doing the design work in VECTRIC Aspire software. I was creating a Christmas… Continue reading

Looking Ahead 2012

I offer a little machine shop rambling today. It’s getting close to the end of another year so I have been taking stock of what I have accomplished this year and what I need to be thinking about for the next year.

One big item is my operation of the “The Hobbyist Machine Store” website store. I already have written that I dropped one of the “me too” product lines. The store is too small to be a good income producing venture. I would have to say it financially compares to being slightly better than leaving my money… Continue reading

“Proofs” of Concept

I was doing some product research today. This is something I made in about five to six hours. I had been thinking of how I was going to make these all week. I just needed a good Saturday to give it a shot.

As the title indicates this is a proof of concept not a real project. I didn’t want to slow myself down doing all the pictures of the process. The process is still experimental so  full disclosure can wait until a better time. I have my camera at the ready.

Long time readers know I… Continue reading

BobCAD-CAM First Test

BobCAD Logo I went through the full set of the supplied BobCAD-CAM V24 drawing tutorials and even though I am not a novice at this 2D and 3D CAD drawing stuff, I feel it is worth the time spent. The temptation is to cut corners and just dive right in. With any software this comprehensive it is best to follow the rules at first. There are many ways to skin a (Bob) cat they say, but it is best to make the first try with someone leading the way.

I am comfortable with the drawing (CAD) part in BobCAD-CAM… Continue reading

Thoughts on CAD/CAM/CNC

I am going to take a time out here from the product specific (BobCAD-CAM) examination I am making of a CAD/CAM software product.

I consider myself a competent self taught hobbyist CNC machinist. I didn’t get here without a lot of study and hands on practical experience. Let me say I have paid for my mistakes as well as my successes. The creative process of following through from an idea, to a sketch, Computer Aided Design (2D & 3D drafting), Computer Aided Manufacturing, (generation of Computer Numeric Control code), Controller (MACH3) set up and finally understanding the physical limitations of… Continue reading
