More learning on machine shop

 Until this year, a machine shop was a mystery to me:   what are the machines there, what is being done there, why they charge so much

1.  Machinery:

     1.  Drilll machine

     2.   Lathe machine (more of a rotary cutting tool for me)

     3.  Sander grinder

     4.  Mechanical saw

     5.  Welding machine

     Hoist,winch jacks for lifting,   Bending machines

   It may or many not have a foundry

2.  What do they do there:

    1.  Fabriication of new part that cant be had in stores

    2  Repair of gears, shafts, welding jobs

    3.  Overhaul

There were plenty of Machine Shops before by Balingit,, Yuson, in Angono Lirio  and Santos.  Now that the old men have died, no one replaced, no one is running the machine shop anymore.  Jesuitas used to have lathe machine and tools for a machine shop.
