"One Perfect Part at a Time"

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

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

Engine Parts

DSC06345What I have in my left hand is six pounds of  brass engine parts. It doesn’t quite look like it yet but it will get there.  I examined my brass stash for the A3 project and it wasn’t as complete as I thought it was. The stash is good but a few things had been “borrowed” and/or are otherwise missing, or I didn’t figure materials as close as I could.

Actually this is probably 300% more than I needed but with projects like this there are minimum amounts that can be ordered. That’s OK as it will all get used… Continue reading

Timing is Everything

I have been setting myself, meaning my workshop, up for the last decade or so, to have the tools I need for retirement. I have succeeded nicely. I just have to force myself to realize I have reached that goal.

I have retired so I have the time and need to start using my shop in its full extent. I am heavy into lost wax silver casting and CNC micro machining. That will continue. But there are other projects I have put off, “for when I have the time.” The Kozo Pennsy A3 live steam locomotive is the… 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
