This on someone I new a long time ago. His one of his hobbies was building steam engines . He would be right home here. His name was?.?Hue Darby

The best I ever saw welding aluminum was friend of family in his 80's .
For rod he used a pocket knife and carved a thread aluminum. Then used torch and weld about 16 gauge aluminum. The best I ever saw. He did aluminum welding in WW2 for from 1942 till 1945. He retire in 1958 and past away riding a bicycle in over 100¡ã day at 99.
He welded was structural steel till 65.
He only welded aluminum for hobbies and models. Was great machinist but did not do machine work for a living
All he had was a old flat belt lathe a buss box and torch. He build fantastic engines

Re: My project thread

 

The wood lathe pulley was a necessary evil.
I salvaged the machine from the scrap pile and there was no pulley for the drive end, so i fitted a form tool to a tool block and mapped all of the features with my DRO.
All of the features including the reamed bore were done from one side without removing it from my chuck.
After the features were completed, the entire assembly was refixtured between centers to face and final turn the other side of it.
?
I had planned to remove the fixturing material until it was time for machining the last features, but decided that a little more flywheel action on the motor wasn't going to harm a thing and it got left behind.

Looks great?

With our reducing magnetic field, we don't need as large a solar event to cause the same problem as the Carrington Event you referred to. So, expect problems.

Think of that happen what would do world today.
Convertering the lathe to petal power or putting a engine to run thf lathe like good old days.

So away look thing I can build .
I can check off the engines no need for a horse ?. Just install one on dishwasher good to go.

Today everyone has a GPS. But hod many can navigate on airplane , drive car or sail a ship with out a GPS.

I bet most here can do navigation with out a GPS and build a Sextant.
