Making Do

I mentioned Mr. Garcia, and his "milling machine".  A significant portion of commenters, like a 100%, wanted to see more of it.  I haven't uncovered it in a while...

Dang, even covered up, there isn't much protection a hundred miles from the gulf coast.  What a swamp.... Our normal weather is hot, mostly 40% to 75% humidity in the summer (March to October).  The winter is wicked for tools stored outside.  We'll get a strong south wind, with a lot of sticky humidity just before a cold front will come in.  A few days of nice cool and dry, then the front backs up as a warm front.  Anything with mass will still be cold, and start sweating like iced tea in summer.  If you haven't swabbed down the bare metal, you are in for a race against rust.  My rust proofing on this tool didn't survive the summer.   Another project for the list....

Okay, here's the mods on this old tool.

Attachment point:

Set at the perfect angle to be sqare to the axis of the chuck.

So, Mr. G fabbed up this square tube, and made angle iron brackets for it.  This is set square to the axis of the quill.

Quill support:
I wonder if those are skateboard bearings?

This beauty is a square tube that nests inside the one above.  It has a plate attached, loaded with bearings.  This supports the quill from lateral forces when you use it as a mill.  Brilliant.

Bearing ring installed:

Looking from the front.
And from the left

These bearings fit right on the chuck.  In spite of this, there is significant wear on the quill.  It's a bit floppy.  It could be, he added this to fix the floppy quill.  But I'm sure he used it as a mill as well.  There used to be an X Y table on it.

Table lift:

He added this bracket, with a crank handle.  That is a bike chain attached to the table, and has a small counterweight to keep the chain from jumping off the sprocket.  Very neat.

Quick belt changer:

He engineered a pivot for the motor.  This allowed quick belt / pulley changes for different speeds.  Normally, this would be a solid rod.  The weight of the motor pulls it tight.  The pulleys are off square a little, but the vee belt doesn't care.  It works perfectly.

Here is what it looked like stock:

I'll start taking it apart next spring for a de-rust and freshen it up a bit.  Provided I get all my winter projects done.  Winter comes on a Tuesday and lasts most of a whole week.  Not much time to get a long list of to-dos, to-done..

  1. Pretty ingenius and low buck to boot.
    Even the Seig Mini Mills are just glorified drill presses, I think I would pull the bearings and head down to the local bearing supply outfit and see if there weren't some bearings that were designed to take the lateral loads that were a direct replacement.
    It also looks to me like you should have kept some of that Scotchbrite.
    You have a project there man.
    I was using some of it yesterday to finish cleaning the post on my frill press. It worked really well until I got real close to the bottom where the flange and the bolt heads are.
    I like the table lift idea too. Mr. Garcia had his heart in the right place I guess.
