Re: [T3] My (redesigned) pulley lock.

I originally found a local place that specialized in aluminum but after a year
of them constantly putting of the design work I decided to work this project on
my own.  The price list that comes w/the software showed aluminum to be almost 5
times more expensive than steel.  Also, using wire EDM was necessary for cutting
the tight and accurate curves for the teeth.  I designed it to be
professional-grade and tough -- quality.  I hate cheap tools!!!!!!!!!!!!

I'm a computer programmer, not a mechanical engineer nor machinist (I just play
one in my garage ;-)  I wish I had the education!  I also don't have easy access
to a shop so I have to get by with what I can find and emachineshop is the only
place willing to do one-offs, as well as batch jobs, for joe-shmoes like me.
Plus the free CAD software used to allow one to design their own stuff is very
cool for me!  Yes, there are definitely much better applications out there but
for what this does, I'm not complaining!  Like computer programming, I'm sure
there is more than one way to make this tool.

Hey, got any need for an apprentice where you work? :-)
