I have a base of my own roughed out, need to pick up some magnets and epoxy

Thanks Wes.

I'll probably end up making something for myself and it is
always nice to see what others have thought up first. I
usually end up with something slightly different, a
combination of the easiest/best ideas and some of my own
input.


That is what makes it yours.

I remembered I had some round ceramic magnets that I stuck to the side of my
snowblower years ago so I wouldn't loose them. I've stared at them for
close to a decade wondering when am I going to yank the package off and use
them. I must have got them cheap

My co-workers base had hard drive magnents in it that made it way hard to
bump the indicator. One ceramic magnet holds it against the indicator
spring, three seemed just about right.

The only aluminum I had was a piece of previously used 2" round stock so I
turned it into some flat stock. Aluminum on a bridgeport with carbide is
like cutting whipped cream.

I used a two flute end mill to make pockets for the magnets.

Pardon the crappy cell phone picture but it is what I had to work with atm.
Since my indicator has a lug on back and no barrel to clamp on the top I had
to do it this way.

That is an Enco indicator. So old it was made in Japan back when we
outsourced there.

My taps and epoxy are at work so I'll finish this up during lunch or in the
morning after I get back from a machine tool auction.

I need to google up info on a Kemp Smith Horizontal and a John Steptoe
shaper.
