I need to make a bigger steady rest and a better follow rest for the lathe.
Actually maybe two follow rests one smaller and one bigger.
My problem is getting slots cut.
I might have to send them off to or take to a guy up north I know.
The man is an expert and a real class act.

For some time I have been using all sorts of stuff for a lathe carriage stop from boards to lord knows what.
Well today I was out fooling around and it hit me like a bolt of lightning.
It doesn't have to be mounted on the ways of the bed it just has to be someplace the carriage can bump it.

Carriage stop coming soon.

Not quite for sure exactly how it will be done in detail but here are the ingredients for the lathe stop.
Three 3/4 10 threads per inch bolts.
One all thread coupling.
One metric 6MM X 50MM Allen head screw to take the place of the shorter one next to it.
Not in picture is four feet of 1/2 inch cold roll round bar stock.
All those bolts and rod coupling cost me two dollars I had in my pocket from selling a used lighter at work.
Don't ask me how I pulled it off the guys where I get this stuff are way cool and why I shop there.
They see me all the time.
This stuff will not look like bolts when I am though, but why bother cutting those threads on stock when you can get what you need for cheap.

Decided to stop for the day.
Here it is so far more or less a proof of concept.
The thing as it is now will work but I am going to make a fine adjustment contraption with the 1/2 stock and 20 threads per inch.
Decided to leave the bolt heads alone makes for easy removal.
One full rotation of the bolt is 1/10th of an inch or .100.

Warning!!!
You do NOT run the carriage up to the stop under power feed or threading it will kill the lathe.
It is for running the carriage up to a preset stop setting by hand.
This allows you to keep coming back to the same place every time without a bunch of fiddling around.
Many uses for it too many to point out.
I had a need, then an idea with a problem to solve then the problem was solved and the contraption was made.
Very happy with this and how it came out so far, a real blessing to have this simple device.

Looks a little less hardware store like now.
Cut unnecessary hex off nuts and turned and faced off the bolts.
I have a short bolt and a long one that will suffice for most operations.

Here is a picture of a device someone made but I have made it simple to look at I think.
This is someones idea of a zero backlash device they made on a video I saw.
When I saw it I knew right off the bat it wouldn't work.
But he thinks it will or does and so did everyone else that commented but me.
What he now has is spring loaded backlash.
everyone one thought what a wonderful idea and why didn't they do this all along.
It is simple it doesn't and cant work.

To remove backlash but not all, you have to force a split nut together or apart on a cross feed adjustment lead screw.
You have to have some they cant be tight or they will just cause wear and you need lubricant to pass through the threads.
There are many ways to make this happen but it has to be positive and lockable in some way.
Not a spring or springs.
The green and the blue represent threads one on the lead screw the other color on the two nuts.

Yesterday I was put to task to make something work.
I wish I would have taken pictures.
Had two other young guys with me.
I had to use files to hand machine something to make it work.
I did one side and asked my coworker to do the other side.
The custom made/machined piece cost a lot of money and there was only one.
Well I had to take it away from him before he made a total mess of it.

How do you do that you make it look so easy?
My reply was a lifetime of using files.
My lesson was this morning I realized it is like playing a guitar you cant just pick one up and play it.
Nor can you do it with a file.
Something I thought all of my life any idiot could do is in reality a very hard thing to do and takes lots of practice.
People that dont know how to use a file think of them as a crude instrument.
People that do know they are a precision tool.

If I were cast back in time with no tools but one, the one I would take would be a good file.

Mostly, it seem to be that using a file is much as Michelangelo said of sculpture: There is a beautiful statue inside this block of marble. The sculptor's task is to reveal it.

In old days it took months to teach apprentices in technical schools to use a file correctly. Even now good filers are needed in aviation industry when rivet heads must become invisible yet keep their strenght.

Years ago I coworker brought a nice JA Henckel knife to work for me to do something with.
It was in the shop I worked in and I used the white grind stone to do it.
The same one we used to grind profile knives for the shaper.
My boss came by and said you are putting a 100 dollar knife on the grinder, in shock.
I hadn't started yet and showed him the knife.
He was flabbergasted it looked like someone had used it to cut stone.
Round on the cutting edge with nicks.
His reply was, "Well I guess you dont have much of a choice".
The coworker had received the knife set as a wedding gift and had no idea how expensive these knives were.
Of course the blade spent more time in the water cooling than it did on the grinder.
Then I finished with a smooth cut file and then India stones.
