Bob,
While you wait for MickyT to post his photos, I offer this information:
I have purchased and fitted both the Clough42 version to an Asian clone 9 x 20 lathe and also the ELS to which your link applies to a new Mini lathe (Amadeal AMA714B). Both installations are available to watch on YouTube should you want to while away a couple of hours.
If the Clough42 kit was still available to UK customers through eBay when I bought the mini lathe, I would probably have gone that route, mainly because I was familiar with it from my earlier project. However, its lack of availability led me to the electronileadscrew.eu site, too. Impressed by the videos, I ordered the single-axis version and successfully fitted it. I must say that, since I fitted it, the two-axis version has become available, and I’d happily stump up the extra €40 for one of those, even if I never got around to fitting a stepper motor to the cross slide. Again, his videos I find impressive. I don’t recognise his lathe, but it’s certainly “old iron” so you might be able to glimpse a view from the YouTube videos and get some ideas from them. From a brief trawl of the internet for photos of Boxford AUDs, it looks to me like the easiest way to connect a stepper will be at the tailstock end with a toothed pulley set-up. Plenty of others have done this with success (not necessarily with Boxfords, though) and published their results online. I 3D printed the mounting brackets for my mini lathe installation to use the existing tapped holes in the headstock which were previously used by the change gears, so that reversion to “standard” could be easily achieved if necessary. I found that PLA-CF was perfectly adequate for this application, and it has shown no sign of flex or distortion during use.
Good luck with the conversion – you won’t regret it!
John
