Re: Mini Lathe and Northern Lights


 

Here in NE TN I saw a bright purple patch through a tiny hole in the clouds but the rest of the time it either too cloudy or nothing to see. There are mor bigger sun spots developing but they dont think the solar wind will hit Earth. I drove 17 miles up into Virginia but still saw nothing even with long exposurtes.

Lathe: 1955 Boxford Model A with screw cutting gearbox, power feed with several accessories, hand tools and a pillar drill press.
Try my Free Online Gear train Software:
You enter a thread pitch or TPI and it shows you a range of gear trains and gearbox setting to use and even a scale drawing of the gear train.
It also includes calculations for taper turning by the tailstock offset method, and cutting speeds.
It includes the specifications for many thread types eg metric, UNC, BSW, and BA.
Displays drill sizes for tapping threads at any percent thread depth (with full explanations).
