Plastic Rut

Man Sitting In deep rut.

Gosh! Haven’t posted here in a while. Got derailed and off track by playing with the demon of three-dimensional printing. You know, push a button and out pops a three-dimensional PLASTIC component.

Pretty much a sit back and watch effort. Similar but different than CNC machining. No chips flying around, or mist cooling required. Additive rather than subtractive manufacturing. It has its place but IMHO not for durable goods. Great for prototyping and making plastic models.

It is not the printing that is the most value. The printer is just another tool. The most value… Continue reading

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

Coasting on the Flat

Maintaining steam but not building speed on the A3. I am coasting at the moment. A honey-do piano stool restoration has taken over the workspace in my shop. Staining, shellac and urethane require a fairly pristine atmosphere. With the cool temperatures and now (finally) a bit of rain the drying process is slow.

Staining is over but I am looking at about three coats of shellac and then a coat or two of polyurethane. Sanding between coats of course.

The teardown and rebuild is the easy part but finish work is laborious. Metal chips flying soon.

Keeping It Enjoyable

runningmanI am catching up on my Kozo Hiraoka Pennsy A3 Switcher project reading. When a project has been on the shelf for a while, I find it good to revisit everything I have done in the past and refresh what lies ahead in the project. It’s all good.

Building a project like this is very detailed. Each step is not all that bad and Kozo has a very good process of explaining the how-to. My enthusiasm is increasing as I can clearly see that nothing (yet) seems to be beyond my current shop tools and my abilities. It’s all now… Continue reading

A Model Shop Story

Maserati_T61_engine_bay_DoningtonI read a story many years ago about a small team of Italian craftsmen. I think it started as a single person but the team grew with demand. They made exact working miniatures of exotic European sports racing cars like the Maserati birdcage. The models are the size of a child’s pedal car, so they were fairly large, but nowhere near actual size. Not designed for riding within. Somewhere around a quarter actual size I assume.

As I remember they were quite exquisite, all real metal construction, completely finished, not kits. Also very expensive, like back in the day… Continue reading
