Looks like a solid professional job!

I see an involute gearcutter attached. It seems to me you can mount it on any lathe, maybe with an interface attachment.

Much nicer than the old school drawing board and handsketches I use. Nevertheless, if you flip the green ruler-reader assy to the underside, you will have the whole mounting surface of the crossslide available for other business.

Some of my collegue horologists who want to downsize purchase as replacement for their larger machines a Sherline or a TAIG. Interesting that it also works the other way around! Trying to put DRO on my TAIG I was faced with the same challenge of not wanting to limit the working space of the...

A simple method is to put the tool on the glassplate of your copier, include a ruler or a gaugeblock of appropriate dimensions and make a high resolution scan. Magnify the scan electronically and measure.

Interesting and simple to let a ball drop in a tube and measure the rebound. I guess you can bring the ball to a correct height by using a magnet on the outside.

What is wrong with a TAIG or a Sherline? Great little machines high precision!

So do I.

For a time I considered cooling with an oil-mist system. But I was warned about serious related health problems. The oil-mist doesn't only attack the respiratory system, but most oils also contain additives that are quite unhealthy and easily attack the body functions through the lungs.

And I still use the woodworkers workbench my grandfather made me for my 10th birthday 70 years ago.

From my experience in The Netherlands you will get much more for the lathe when you 1) clean it up really well 2) decide on the minimum of the stuff to go with it, like a chuck and a simple toolpost 3) sell all the other stuff separately.

Luckily I'm into building clocks. While engines need close tolerances to run well, clocks need to rattle a bit in order to run at all.

Hi ChazzC, 0,0001" sounds like 2,5 microns. When instructing my three grandchildren on working in my machineshop a standard action is to let them measure the thickness of a cigarette paper with a micron measuring dial instrument. They find that depending on the brand that thickness varies...

Hi Danuzzo, on my TAIG I mounted a 300 Watt 24 Volt DC motor of nominal 6.000 rpm. It was originally intended for a robot-actuator. With the DC controller and the original pulley set I get a rpm range from about 20 rpm to 20.000 rpm. The high revs are useful for drilling holes well under 1 mm...

I noticed this thread a bit late, but anyway: for high strength combined with low internal stresses and very good machinebility we prefer the Swiss made special steel ETG100 or ETG 80. Excellent for gears, spindles, crankshafts and the like; in general components that undergo lots of machining...
