Is that for practicing using the lathe in general or threading specifically?
Both. Look up the thread pitch for the small disposable propane bottles. 1in PVC can be turned both inside & outside to fit. Suggest simply cutting first, slow speed! While you get used to the clutch & half threads.
Additional "advice." If you decide you want a quick change tool post, I strongly suggest you save, cry once & buy either of the two US made. Till then what you wave will work fine. Other than that, A Shar's tool post is, IMHO, your best buy. The Chinese tool holders tend to work fine on any tool post. I have two to part with, use my profile to send me a note if you are interested. Both are low time not that it matters.
Do NOT be tempted by the cheap carbide tooling. It MUST be sharpened to work well, and that's best done on a diamond wheel. Others will say a regular wheel is fine. Whatever.
If you decide to go with inserts, do yourself a favor and get David P. Best's book on indexable tooling. Money very well spent IMHO. 1/2 is a good size for your 11"
High Speed Steel (HHS) is what this lathe was made for. There are several options in addition to traditional hand grinding. A.R. Warner makes insert HHS tooling. My favorite is Eccentric Engineering diamond or tangential tool holder. Again, cry once. But they sharpen quickly and often a simple honing will sharpen them right up. He has YouTube videos on them.
On YouTube look up Blondihacks. Quinn has an excellent set of beginner videos. She also uses a Diamond Tool holder a lot in her later videos. MIT also has beginners lessons. Mr. Pete has hundreds, but not as organized. On his web site he sells lessons specifically for a Logan 10" the 11" has identical controls. Money I'm not sorry I spent.
Please continue to ask away, and others may give good reasoning for other opinions.
EDIT: Remember, the school of hard knocks is rarely cheap and often leads to stories that are only funny after some time has passed. Tooling will over years often exceed the cost of the lathe. A little bit at a time. Good|Quick|Cheap. Many enjoy the tool making aspect of the hobby regardless of the time required. Others not so much so buy what they can to get their project done. Over time you will figure out your balance. The search tool here will help you find many previous lessons learned to follow up on if it's not quite what you need. But looking first will win you a lot more willing help when a question has already been answered 10 times. FWIW.
