V10-P Emco Chuck Removal
|
Good morning.?
I just acquired a V10-P which externally looks to have been well maintained. I have yet to get it into my shop and will likely have many more questions as I begin to clean it up.?
My initial challenge is getting the lathe out of my truck and I¡¯m working to remove any extra weight including the chuck.?
Before I damage anything I thought I would reach out on the proper method of removing the Emco branded three jaw chuck. I¡¯ve loosened what appears to be a locking screw behind the chuck but I am curious as to the next steps (pull off, screw off, ??). ?If screw off, what do you clamp onto? ?I¡¯ve seen an instructional video where there are slots in the back of the spindle but those don¡¯t exist on mine.?
I¡¯ve attached a picture in case it helps.?
Thanks in advance for what may seem like a silly question. ?
I¡¯ve been using a Compact 5 for the last few years and I suspect there are quite a few differences between the two machines that I¡¯ll be learning about.?

It unscrews, regular right hand thread, ie, turn it counter clockwise when looking from tailstock to headstock. They can be pretty stuck and care has to be taken when undoing them. In regular situations, you put the gearbox in the lowest gear and unscrew the thing by hand(s). Jerking it makes sense as well... but if that is not enough to loosen the thing you'll want to search for "stuck chuck" topics. No hammers, levers, etc. In any case, the whole machine is on the order of 150kg, chuck is maybe 10kg of that and tailstock is another 10kg, so not much better. Taking off other pieces is not worth the trouble unless you intend to strip it all down anyway. You'll need an engine hoist or some sort of crane to lift it by yourself. Two young (and athletic) people can just about move the thing, three are better if you can find them. Regards Vedran On Mon, May 26, 2025 at 7:46?PM Djed.geo via <Djed.geo=[email protected]> wrote:

Best way, put straps through the webbing in between the ways. I don't have a picture of that exact setup, I have one when I've had the leadscrew and feedshaft off, so I just strapped it around the bed. You can't do that when it's assembled as it will bend the leadscrew and feedshaft. This is about where you want the straps to land - yes, it says "lift point" on those pieces of tape :) I remember I marked them when I found a good balance point. That was with empty headstock, no norton box, no change gears and no tailstock, but possibly with the stand so maybe move the left one a bit further left. Don't lift by chuck, headstock or carriage. As long as you're strapped to the bed, you're probably fine. Thing is not exactly top heavy but it's not far off either. I don't remember it trying to capsize on me (like a ship), but wiggle it a bit when it's barely off the floor to check for that. oh yeah, good luck and be safe :) Regards Vedran On Mon, May 26, 2025 at 8:45?PM Djed.geo via <Djed.geo=[email protected]> wrote:

One piece of advice I would give if you're manhandling it (if you haven't already removed the Power feed gearbox) is definitely remove the selector knob(s) from the front (it unscrews with a flat wrench/spanner - just pull the outer to reveal the flats). If it rolls and lands on the front this will break the selector arm for the gearbox and they can be ... troublesome ... to find replacements for. I speak from experience here. (OK I repaired mine but it ain't pretty)
