Have to exercise self-restraint or you will have many Barnes machines.
The #4-1/2 with legs removed will fit in most cars. I hauled a #5, which has a longer bed, 900 miles in a rented Toyota Corolla.
In fact, if you have a Radio Flyer red wagon, you could probably use that. Might be a long trip, however.
One strong person can uncomfortably pick up both ends of a Barnes 4-1/2 minus the legs and carry it carefully to a landing spot. Two people is safer.
The legs can be carried two at a time, one in each hand.
Check to see that it comes with a full set of gears. There should be 12, or possibly 13 (to get the elusive 27tpi for pipe thread) in total. The large one (88 teeth) used normally on the lead screw is the one most commonly found broken (by those who carry the lathe NOT carefully) and the most difficult to find intact on Ebay or elsewhere. The others are fairly common, CAN be bought at Boston Gear (DP16) but bring yer wallet, and most easily found on Ebay (and easily confused with Barnes No. 5 gears which are DP14 and don't fit - check your OD diameter and tooth count.)
Barnes 4-1/2 is fortunate in that tapers in spindle and tailstock are both Morse Taper 1 which makes tooling readily available, albeit a bit small. But proportionate for this size lathe.
One of the nice features of the Barnes lathes are the center mounted revolving cross slide - doing it this way allows one to use the lathe to cut "spheres." One has to be mindful of placement of the carriage for this action.
They're not a bad lathe. The reputation of being a "farmer's lathe" and always being found in a chicken coop and somehow something less than a "real" lathe is somewhat undeserved.
Said even though I found my Barnes 5 in a chicken coop.
You have a motor drive available on this one and I can verify that motor drive is preferred for a "user lathe." Pedaling somehow just doesn't cut it for any amount of stock removal. (which is where I'm at now with my Barnes 5.)
As Ed Battison (Founder/Director of the American Precision Museum) said to me on my gloat to him on having found a nearly complete Barnes 5 lathe with velocipede drive:
"Now you'll find out the true meaning and value of "keen" tooling."
