Old School

You might be Old School if you ever had an Old one lunger /Lathrop in your fishing boat. :immersed:
 
Old Schooling today.

1940's era Warner and Swasey turret lathe, 3 1/2" 1045 TGP steel rounds, had to drill 11/32" holes 9" deep and tap 1/8" NPT.
Used 4 drill chucks in the turret, jobber length drill, 14" long drill, countersink and pipe tap. Worked a charm 8 parts in 4 hours including part handling.

You might be old school if you penciled programs

Challenge yourself by solving the problem with
no computer, just pencil , paper, and trigonometry table
No answers needed.

I chased an ice wagon that was pulled by a horse. And boy did the driver get ******.
 
.517 X the rhombus / collateral angle in degrees Kelvin for metric units

This can not be solved in inch units as the rhombus declination is undefined.
I hope this helps.
 
Don’t give up guys, there is a solution.
Someone will post it
 
Sure looks like 0.500" in the X direction to me. No trig tables handy, but y=0.375+0.5*sin(0.5/0.625)?
