Hi Anthony,

Thanks for the advice. Really appreciate it a lot. It'll take time before everything starts to click but I'm very hopeful. It is becoming easier as I go along and I can visualise what needs to be done.

When I started out it was like moving through a fog that's why I set my goals low and not be too adventurous initially.

I just want you all to know that you do make a difference.

I'll update you guys on how it turns out. I'll get a few pics and upload it via the PC at work. Am still fixing my home PC.

Regards.

If every machine had a DRO on it then you would never really have to think about backlash again

I hope you don't mind me sticking my nose it but the above is not strictly true. I know what you are getting at but some new guys might not.

When you feed at tool in you want the backlash in front of the cutting forces so that the tool does not get pushed back during the cut.
Normally achieved by always feeding towards the work. If you go too far and pull back just make sure you pull back far enough to necessitate the need to feed in again thus taking up backlash.

But yes the DRO will tell you where you are when the dials may not. What the DRO won't tell you is where the backlash is. :thumbup:

I hope that make sense :scratch:

On the contrary your input is more than welcome this is what this forum is all about.

Its funny I thought I explained what you remarked on, I am sure there’s always this, three people can read the same thing and get three slightly different views from it, I know I suffer from it.

Yes you are 100% right DRO will not inform you of your backlash.

I have a Atlas 12“, its about 30 years old I have had it for about 12 years anyways the cross slide is so sloppy always has been I have given up on trying to keep finessing with the Jib screws, religiously I drive forward about an inch get close to my cutting position and when ready I pull with my hand back on the cross slide to bed it, seams to work for me. I also have the jib screws tight more than I should. Which in turn plays havoc on my wrists.

Its an awkward machine to use, but after knowing and using it for so long now and I know all its quirks it produces some nice stuff.

All the best. Anthony.

My lathe has a DRO, and it shows you where the backlash is when the crossfeed moved during cutting.

I recently had to do some boring, and I had to move the took towards the work, but back towards me. So that jives with what Darren said. Took me a few passes to get the idea.

Similarly, when using my taper attachment I need to cut from the large towards the small end of the taper for best results.

Hi Guys,

Just for an update. I managed it with confidence. Problem is, on the one pulley I want to remove the bush now but can't. That's typical of some of the situations that I get myself into.

Thank you all for assisting me.

Regards.
