@Ed Jarvis, do you have a price threshold which cannot, shall not, be violated? If I knew that number, I could give opinions, at least based on my personal ownership over the years.
I really dislike Delta inventing the term "midi lathe" as their answer to the Jet "mini lathe". Just a dumb word. Anyway, is the 14" category a starting point in your search? Is 12" off the table, and 16" out of reach? Even these numbers are a bit arbitrary, because price is usually what turners have to limit themselves to.
I currently have a 23 year old Vicmarc VL200 shortbed, 16" x 16". This IS a "lifetime" machine, I'll never wear it out. They also have a VL200 long bed version. But Vicmarc lathes are a financial stretch compared to some other makes, unless you build up a bare lathe yourself. I also have a 2-year old Oneway 1224 (midi, my arse!) with accessory bed extension. 100% of my turning interests are covered by these two machines. Heck, a VL200 long bed would make me a one-lathe turner. Honestly, my Oneway 1224 w/extension makes me a one-lathe turner. Anyway, I've also owned a 24" lathe (yeah, a Vicmarc), and two separate 10" lathes (Jet 1014, followed by the higher quality but very similar Vicmarc VL100). So, I've been all over the map, size-wise. But my project size interest has remained consistent over 30 years of turning- the diameters I show below.
I'm sitting at my kitchen table right now. Grabbed a tape measure and grabbed some dishes. The dinner plate on the left, 10-1/4". The small plate, 6-3/4". The bowl, 6-1/4". I could grab a mixing bowl or two to expand the research. This is an easy exercise for a turner, a new/upgrade lathe buyer, to help guide the lathe purchase, to put some reality into the purchasing decision.
All three of these items, shaped as bowls or plates or vessels, can be easily turned on a 12" lathe. (Yes, at some diameter the lump of wood may compete for space with the banjo, but that won't be every project, and it can be worked around.)
I've been referencing Richard Raffan videos a lot in recent times (and why not? 50 years of professional turning), and for the last 3-4 years he's been shooting a lot of video running hard a 12" lathe to make wonderful, practical-sized turned objects, both utility and artistic. That said, he just now stepped it up to a 16" lathe for, I believe he stated, the extra mass of the bigger machine vs. just wanting more swing. He mounts some wonky chunks of wood and runs them at high speeds making heavy cuts.
I don't have a direct answer to your direct question, but hopefully I added some food for thought to guide your decision making. Maybe you'll be able to focus in on a machine that meets your actual and not just perceived needs and wants, and you'll find the way to buy the best quality machine in that size range to suit. I have no interest in restaurant-size salad bowls- made three years ago and quit. Lots of work, lots of mess. Smaller size wood (12"-16" lathe size wood and smaller) is far easier to come by, far easier to process, and offers, to me, anyway, every bit of craft skill and artwork potential to satisfy my turning desires.
(Original question- "
Which of the 14" has the best performance and trouble free history?" If price were no object, and sticking to a min. 14'ish inch machine, in no particular order there are three I'd consider- Oneway 16" series, Vicmarc 2xx series, and Robust Scout or Sweet 16 series.)
I hope this helps your purchase planning.
