Title: Hammer
Post by: kartjockey on March 29, 2020, 09:57:32 AM

Just a little story for ya's.  I made this hammer while in high school.  They offered Machine shop I  and Machine shop II. This was while in shop I. My dad had the same class and same instructor 30 years prior.  He had also made this hammer and some where through my growing up it turned up missing.  (must have been my brother!).  While in shop class the instructor was super cool and would let me work on my own projects then would grade them so I could earn an honest grade. But in this case I did end up making the required project to give to my dad on his birthday. This hammer had several different operations to learn such as turning, knurling, threading and milling the flats then also grinding them for experience on a surface grinder. The handle was drilled out to offer balance.

  I had kept a photo copy of the blueprint but just recently doctored it up a bit and turn it back to blue.

Also made a bench grinder from a casting.  I now have my own plus my Dad's.  Kind of convenient because I can keep different wheels on them.

Brings back some good memories . The shop in my high school was more equipped for wood working than metal .

This was Dads. So 1951. Mine looks the same except paint is newer! 1981. Blueprint is an original that is under UV glass in a frame so photo is a bit skewed.

So flat milling the base, bore for brgs, turn shaft, one end is acme thread and other end is a square thread. Some bench work, Keyway broaching.  pretty much every operation to learn about.

I wish I got to do that in school. Our projects were not nearly as complex.

Wow! Those look great!  I wish I would have had a teacher that would have taught us that kind of skill!  I did get to take a go-cart in and I made a frame on the back of it.  I installed an engine and a  3 ft. propeller.  We took it out in the parking lot but it never had enough rpms to move it.  It's a wonder no one was killed - there was no safety shield around it.   :D

Also made this in high school.  Never went to anything but was for the experience of making a gear.  36 teeth.
