7x14 to 7x16 Rebuild

Don't understand you saying that you won't need a lead screw. On my ELS, the carriage position is changed via the lead screw and the half nuts. Basically, I have disconnected the mechanical linkage between the lead screw and the spindle. Then added an encoder to the spindle and a stepper motor to the lead screw. The linkage between the spindle and the lead screw is now electronic. What are you doing?

@WobblyHand

I never said anything about not using the leadscrew. What I said was, and I quote

With an ELS kit, I doubt I will use either leadscrew for screwcutting using change-gears, but the option is always going to be there.

I glossed over the "using change gears" part. I simply saw the "I doubt I will use either leadscrew for screwcutting" part.

This is what happens when you drive for 10 hours, the last 7 of which were snowing profusely and then post on HM. Next time, I'll wait a couple days for all my senses to return. As you were.

No worries, we all have off-days. Me more so than most I would hazzard.

As for the change-gears thing... I am leaving the full length leadscrew in place, as well as the gear train, but parking it in neutral. At least that way, should the ELS fail, I have the original system in place.

I've kept my change gears, they're in a box in a cabinet. But I have no idea why. That's because I have no intention of reverting my ELS set up.

The ELS is so nice (in my opinion) I can't see why I'd put back the greasy gears and deal with flying e-clips. A well running ELS is just wonderful. I'd wager that you will feel the same once you get yours going.

I very well might stick purely with the ELS but as I say, If the ELS fails, at least I will have the option to fall back on the original change-gear system.

Always have a "plan B" in the back pocket. You never know when you will need it.

Flying E-Clips??? The setup on the 7x uses SHCS to keep the change-gears in place.

I installed my ELS on a 10x22 lathe. It used an e-clip in one location. Installing the e-clip was easy. Removing an e-clip usually launched said clip into unknown regions in my 150 year old basement. I had about a 1 for 4 success rate at removing and finding the e-clips. But truly, an ELS is so much more convenient than manually changing gears. Can't conceive of a plan B, the ELS is far easier to use.

I also have a 7x16 mini-lathe. Like yours, it uses SHCS to hold the change gears. Haven't figured out a good way to modify mine to an ELS. I have plenty of spare controllers (made my own), just haven't engineered the mechanical parts. Of course, with a running 10x22, there is no "need to" convert my mini-lathe. Might be a nice side project, however.

@WobblyHand

Dropped you a DM regarding the ELS on the 7x. Not sure if you will find it of use, but as they say "Watch this space" because I am going "a different way" with my ELS install and for very valid, for me, reasons.
