Re: What projects are you doing?

I've not tried to turn threads.? Now that eyes are fixed from
cataract surgery, it's about time to upgrade the mini lathe to the
16" bed.?? Many amateur radio/ham radio projects I need to do but
have been putting off due to vision problems.

And I'm still trying to learn how to turn threads !

Project? ?
My last big project
was a CNC conversion of a HF Mini Mill. ?I added
computer contoled motor to all three axes. ? Now
I¡¯m on to the current project which is robotics parts. ??
Many of the parts
are 3D printed but there are metal parts that need
turning and some milling. ?And some of the plastic
parts need finish work on a machine tool.
3D printed
plastic is only about as accurate as metal
castings so I have to machine the plastic where
it touches precision metal parts. ?The Mini
Lathe and mini Mill are good enough for this
because I don¡¯t need to make high-precision
parts like bearing races. ?I buy sealed bearing
units and press fit them into the plastic parts.
?I make the metal shafts and other small parts.
?In total, there are 12 motors, 60 sealed
bearing units, 24 timing belts, and lots
of?opportunities to do small-scale machine work
The current
project is a robot quadruped that is the size of
a small dog. ?It is based on a design by ODRI
but redesigned for lower cost. ?Right now I am
prototyping parts, nowhere near ready to
assemble a complete robot. ?That may happen in
2024. ??
Someone at a
university made a video that shows the basic
design and then the parts inside. ?All the
details are different in mine but the basic plan
is the same.

Here is one of the subassemblies in my
version. ?You will need to use the ¡°exploder¡± to
see inside and the rotating in 3D to see the
exploded parts.?
My advice about ¡°setting up a lathe¡± ¡ª Make
parts, then if the parts don¡¯t come out with
enough quality, figure out why and fix that
problem. ?This way you only fix what matters and
you actualy get stuff done.
