Working on micro hydraulics looks so cool!  I've worked on massive shovels and loaders which have huge cylinders, I wish at home , I could build and work on what you have 

.  ..... I guess I can leave my 2 1/4 wrench at work for this stuff eh?
I have no kids, no college fund to worry bout. My plan was retire at 55 .......

  now I got the RC truck bug and because of my career, it's only a matter of time before I have a shovel, dozer or loader of my own 

My new plan is retire ?........someday....

.  Lol
