Steady Rest

I used a steady rest for the first time on the Logan.  I've watched folks do this a few times, and since I was just knocking rust off, I figured it was time to try it out.

Genuine Logan Accessory

I'll include a link to how to set these up.  Or maybe a couple links.

Here is Mr. Pete - This is the gospel according to St. Lyle

Here is Joe Pie up in Austin Texas - This is the high precision, professional way

Here is Quinn at Blondie Hacks - This is the hobby machinist view

If you look close, you'll see some black tarry goop on the tubing.  That is something that Mr. Pete mentioned some years back.  When I was first starting, I'd watch Mr. Pete and if he said it was good, it was ordered.  I've had this stuff for a while now, and it works as advertised.  I shudda bathed in this stuff this year.

Extra Credit Question:  What was Brylcreem's tag line?  

My runout at the rest was about .010"  Not good enough for precision work, but okay for a red Scotch Brite® 7447B scrub.  That stuff knocked the rust of easily.  I used a doubled strip about an inch wide, backed by a file.

I did some smaller shafting previously, and there was this wafting fog of rust dust moving around while I worked.  I wiped the ways after I was done, somewhat OCD about this Logan.  Mr. Garcia did a great job of maintaining it from 1946 until he passed in the early 90's.  I got it after it sat for 10 years.  So, I don't want to offend his attention to detail by being a dip.

Hmmmmm.... how to protect the ways?  

I took a paper sack, like civilized people used in the pre-enlightened age.  You remember that time right?  Back when trash could actually decompose over time? Or you needed to start a fire in the fireplace or wood stove?  Or you needed to protect a borrowed book? I used some old hard drive magnets to hold it down, then hit it with a light spray of oil (WD40 works) to latch onto the dust.

Not borrowed, but I still want to keep it protected!!

It worked well, and I still wiped and lubed the snot out of the ways.  Oh, about the book.  I'm a "nuts and bolts" guy.  I like to know how things work, like, how EVERYTHING works.  I can't help it.

This is an old school steady.  It has rubbers not rollers.  That may need to be rectified/retrofitted at some point in the future.  But this worked well for me on this job.

Thanks for stopping by the shop.
