A couple years ago, I made a very quick and dirty rotary broach for a project i was working on in my normal job
it worked for the purpose it was intended, but i wanted to make an improved version.
I purchased a beautiful Hercus ARH lathe a few years ago.
i love this machine, but the original owner didn't wire the drum switch for direction.
it only ran in the spindle CCW direction ,whichever...
I came across a wonderful find on CL.
a gently used 1979 Boyar-Schultz H618 surface grinder.
this unit was purchased new by the previous owner and saw a good life.
we pulled the table off and i inspected the ways, the ways are very nice indeed with only the very faintest signs of wear.
i got the idea to make my own dial indicator holder for my AXA toolposts
i have an modest abundance of 2" square solid 6061 aluminum in different lengths up to 5' long
it has holes and tapped holes from when it was in service as meat processing equipment,
so i cut it into differing lengths...
i'm certainly no carpenter, and definitely not a furniture maker.
my brother has a dresser drawer that had a dovetail slide under the drawer that had broken.
the problem is that the female half of the dovetail has a very thin cross section at the base of the dovetail.
to compound the problem...
I have a horizontal rotary surface grinder that is used to flatten and sharpen many different items at the shop.
I have a few different wheels that get used for different materials.
I found a good deal on some wheels i haven't used in awhile.
The problem is that the drive arbor hole is smaller...
Hello ladies and gentlemen,
i found some very interesting videos on youtube.
i believe they were produced in the 80's at a guess, but very good information
here is the video list:
and a sample video.
i hope you enjoy!
i started construction on a MT3 slitting saw arbor from materials in the shop.
here is the slug of what i believe to be 12L14 mild steel.
it was unmarked, but acted like 12L14 i have machined before.
it's very nice to turn.
the slug was a fraction over 1" in diameter and 7" long.
I learned of the Antikythera Mechanism in High School from my chemistry teacher, in one of many after school discussions.
He explained it as a complicated and intricate mechanical computer made by the ancients, boy he was not kidding.
i really didn't gain full appreciation for what it may have...
I have a good friend on Google+ https://plus.google.com/u/0/108774772276210693588
he makes cool steam engines and other stuff
in this video he built a walking beam engine from a vintage erector set he found at a swap meet.
i was messing around in the shop last week.
i made a couple videos of me playing with stepper motor drivers and pulse generators.
i took a small bipolar stepper motor and controlled this motor with 2 different stepper drivers.
i did the experiments to make comparisons between the 2...
I made reindeer from logs this year for fun and they turned out very cool.
the bodies are made from cedar branches.
the necks and heads are made from cherry branch,
the antlers are manzanita brush
the legs are apricot twigs.
i used 1/16" e308l tig filler rod to attach the head and neck to the...
I scored on saturday!
i got a collet rack from member @bfd, (Thanks Bill!!!)
he couldn't use it because he didn't have a round column mill.
i don't have a round column mill that needs the rack.
i decided to modify it to suit another need on another machine with r8 spindles
it's for my Trans...
i purchased a set of inexpensive collet block's from all-industrial tool supply for use in my lathe and milling machines.
they were shipped fast and are very nicely finished, better than i thought i might get for the price.
i don't have any connection to the company, but i had a good experience...
I use my Shenwai SW900B lathe to do a lot of my projects.
this time i wanted to make a full-time tailstock center drill holder,
the problem was that i never cut a morse taper before on a lathe.
i doubted my ability to make a concentric tool with a MT2 taper that actually worked.
that had to...
