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.

Will 3d printers replace parts factories, machine shops

Complete repair/rebuild of 6 cylinder Nissan Diesel Engine

 This is admireable.  With limited machinerry repair and measuring equipment.  But judging from the way the engine purrs they must have done an admireable job.

If we compare the Western repairs:

1.   Proper use of measuring tools:    torque wrench, roundness gauge, calipers

2.  Clean workplace

3.  Proper lubrication

4.  Plenty of helpers in Pakistan

5.  Westerners would always go fornew complete assemblies which undboutedly are more expensive

With limited knowhow and equipment these workersk/craftsmen have done a wonderful job

Roadside repair of jammed truck transmission

 It could be misleading because the transmission unit was removed and repaired at a machine shop.  This was probably in Pakistan.

However it was a superb job.  No need to tow the heavy disabled truck.   Only a tricycle was used to transport the damaged transmission.   We should admire the mechanic who know excatly the sequence of the gears.
