I hope not, Bob.....if it comes up, I'll have to call in some help. Doc hasn't cleared me to go back to normal work yet, and I figure changing a chuck is out. The smallest presently mounted is a Strong brand 10", then a couple of 12's or larger. One of those machines is just idled at the moment so not an issue. 10" 3 jaw is way heavier than I want to lift right now.
Been sitting, thinking about your problem and may have come up with something that I will want to build for myself. You have issues drilling into the concrete right behind the machine? I'm thinking of a sawed off jib crane. I have built a couple of full sized, 4 ton units, and I think it would be a very simple job to built a small one. I just happen to have a 500 lb electric chain hoist .
Oh, and naturally, the one lathe I never use actually has a sort of jib swung over it, good enough to handle chuck changes and steady rest mounts...oh well. Guess I need to wire it up and start using it.
Oh, and btw, what you are thinking of I believe we call in generic terms "sheetrock". It is pressed gypsum with paper on both sides and comes in thicknesses of 1/4 to 5/8" (as far as I know) and standard sheets are 4 x 8 feet, or 4 x 12 at times, used mostly in commercial work. The joints are filled with a water based gypsum "mud" and paper tape. Sometimes just called "drywall". Largest maker may be using the tradename sheetrock, and is US Gypsum IIRC. But I can understand your reluctance to open that can of worms.
