Re: Extending cross slide travel -- what is the currently accepted best method?
For my needs, the LMS kit lacked extended travel away from the operator. I need to be able to move the tool holder past the chuck for a part I make. I have a fixture in a quick change tool holder that

Ryan H wrote: I have a mill, several. Curious what was lacking in the LMS kit?? it seems to achieve both more travel and relocating the travel.? The same as "the Mike route".? Obviously it's $$$

Re: Extending cross slide travel -- what is the currently accepted best method?
I just finished up? an extended travel mod on my 7x a couple days ago. ?? I don't have access to a mill to cut the carriage and the LMS kit only addressed part of what I wanted to do so I did it

Re: Extending cross slide travel -- what is the currently accepted best method?
My understanding is that the Gordon Scott mod moves the effective range of the leadscrew towards the operator (so you can cut wider material since you've moved the cut position relative to spindle).?
Re: Extending cross slide travel -- what is the currently accepted best method?
I did Gordon Scott's method years ago & have been pleased with it. Roy

Extending cross slide travel -- what is the currently accepted best method?
I need to machine some wider material. Googling I can find lots of approaches and I'm struggling with what is considered the best approach in 2022 (ideas tend to evolve). Gordon Scotts:

Re: Saddle/Carriage adjustments
After cleaning the metal chips out of the gears in the apron; I used my scroll saw to make a plastic cover for the gears. To grease the gears I used some Mobil synthetic grease. Now the carriage moves

Re: Saddle slop -- source, solution(s)?
You make a good point, Mark! As long as it is performing to your satisfaction all is well. Over time the saddle should settle into a comfortable spot on it¡¯s own.

Re: Saddle slop -- source, solution(s)?
Update. I found some adjustment issues with my saddle's shimmed slide plates (say that 3 times fast!).? Their mounting screws had loosened up a bit over time, permitting the saddle to ride up a bit

Re: Saddle slop -- source, solution(s)?
John, I was in the process of performing RDM when I found the issue described in my original post.? Since the saddle is unstable there was no point in continuing with RDM until I figure out what's

Re: Saddle slop -- source, solution(s)?
Mark, I ran into saddle slop and found it was caused by ridges in the carriage "V" on my lathe. It is worth checking for this since it is easy to detect and fix.? See:

Re: Saddle slop -- source, solution(s)?
I hand scraped all the sliding surfaces of the carriage and cross slide on my 7x16. I was also able to get the cross slide scraped square so I am able to face square with .0002¡± concavity over 1¡±.
Re: Saddle slop -- source, solution(s)?
I agree with Roy. The top surface of the bed is the only precision ground part of the machine, so don't lap or modify it. What you do is use the surface of the bed as your reference for modifying

Re: Saddle slop -- source, solution(s)?
Mark, I think .005¡± variation is a lot over 10¡±. I think it sounds as if there is a issue with the fit of the saddle as you eluded to. Is the saddle pivoting or twisting on the ways? If so, do you

Re: Saddle slop -- source, solution(s)?
The top of the bed is surface ground at the factory - it's the? reference surface for everything on the lathe. The mating surfaces on the carriage & HS are NOT ground & may well be misaligned. Check
