WW I Machining Advances

I'm reading a book by WWI pilot James Norman Hall that mentions US manufacture of the Hispano-Suiza engine. We learned to meet tighter tolerances from the French and they learned about high volume production.

WWI saw the first mass usage of arc welding for ship construction.

Previously, iron hulls were only rivetted and arc welding provided far faster construction - needed due to the losses due to German Submarines.

US Submarines also had welded hulls.

Big increase in the use of die casting and much progress in the field during the "great war." Also use of jigs/fixtures and automatic machines to allow unskilled labor to produce munitions.

A bit of a disapointment. The program got changed and the topic was about how Blackjack Pershing insisted on maintaining separate commands of US forces. The French and British wanted to merge US troops with their forces but Pershing insisted on separate commands.

Also discussed was the roll of African American troops in the war. The colored troops WERE assigned to fight with the French and aquitted themselves quite admirably.

Thanks to those who offered suggestions!
