Hi @osariemen! Welcome to Steemit.. :)
It is a good start though! In the Mechanical Workshop classes during our Second Semester in Engineering classes we came across this Manual Lathe Machine uses which you have explained very nicely above.
But please be careful while putting the references as @terrylovejoy mentioned in the comment and rest things you will come to know with time..
Moreover, if you find any difficulty you are always welcome in the general chat of #steemSTEM on discord to clear your doubts.
Wishing you a very happy time here! :)
Cheers!! :)
Thanks for the correction and encouragement
