Fanning the Coals

It’s no secret one of my lusts is machining in metal and wax. Actually, machining any material is fine with me. Wax became my favored material because it machines so well, especially with very small tool bits. Primarily, jewelry CNC carving for lost wax casting (LWC).

But I have also machined wax for LWC casting in brass, and that also works very well. I am not involved with casting large objects. At least not yet. But I don’t have an interest in doing large scale sand mold type casting. That’s a whole ‘nother sideline.

My light weight Taig equipment is… Continue reading

Proxxon TBM 115 Micro Drill Press

DSC06356I ordered in a Proxxon TBM 115 for personal testing because a visitor asked my advise on small or micro size drilling.  Not ultra small drilling but in the number drill range, about 1/64 and larger. I immediately thought of the TBM but never used one.

My Proxxon dealer status is still viable so I ordered one in for my evaluation and perhaps passing it on to my new friend. The truth is I may keep this one for myself.

I have published a full, first look review in The Hobbyist Machine Shop. I was a bit undecided whether to… Continue reading

Take Your Best Shot

Taig Derringer (NOT!)There is a HUGE amount of BS on the internet forums about proper size CNC hobbyist machines. Internet opinion forums and blogs, because they are unregulated, have become impossible for a newbie to determine fact from reading someone’s personal agenda. Don’t trust anything you read including what I have to say. Just take what you read for what it may be worth to you.

Every brand, design, size and cost of a machine has it reasons. Unfortunately, what amounts to urban legend has driven the uninformed hobbyist to believe there is always better quality available for a lower cost; the… Continue reading

Having Fun in a Micro Machine Shop

I have been writing about small machine tools lately. I have said there is as much and actually more fun in making things with micro machine tools as the larger type. The Taig micro-mill and micro-lathe are a great example of the small size tools to which I refer. The Sherline products are just as capable and have a much larger product line. My preference is the Taig as the base hardware. I am not going to argue over tools. I own what I like, but know it is not a good over bad choice between either of those brands.… Continue reading

Grizzly Disk Sander/Grinder Switch

Quite awhile back I purchased a Grizzly G7297 12″ disk sander/grinder. It is one of the most used power tools in the shop. Sometime I just have to grind something off flat or square and this is a fast and accurate way to do it.

The switch is apparently the weakest part in the machine. It stuck in the always on position. As you can see the points are badly burned. The concept was good as it is a double pole single throw (DPST) switch. Both power and ground are broken when switching off. But not good when they… Continue reading
