I am going to “true” the “ways” on my grinder.
The ways are 11-1/2’ long, about 1-3/8” wide and about 20” apart. The head travel 8’.
First I need to assess accurately just what I have.
Then I need to make corrections.
I would like to map it out about ever 1 inch or so.
So – how do I do that? I don’t think levels alone will tell me enough.
I don’t think piano wire is accurate enough, but it is an option.
The only thing I can think of is some form of laser or optical device.
Of course I would like it to be as accurate as possible but I think I would be happy if I could get it to within 0.005” over the full length. A small deviation over the full distance is tolerable. Small bumps and dips in a short distance are not.
Then how do I correct it. Is this doable by scraping? Perhaps a temporary rail trolley setup to move a grinding head over it.
I will add a picture if I can do that as a new member without prior posts.
It is a Gockel G30 with a 10HP head.
The ways are covered with a strip of spring steel. The head rolls on 4 steel rollers.
The ways are steel not cast. They have developed a small crown across the width.
I know there is lots on information I am not including here but did not want to make it too long.
I need to be able to do this with only putting it out of service for a week at a time. Could be multiple times.
If there are short low spots could I fill with Belzona product or something.
I am not a machinist but was an industrial mechanic.
I can spend a few thousand for gear but not much more.
Thanks
