I aquired this some years ago and have yet to understand it. The lable has worn badly and all I can make out looks like it says "The Gra_____"
It was made in the US by Delta and appears to be a lathe of some sort, but what sort?
There is both an inboard and outboard 1/2 inch flatted shaft on the headstock and both sides have marks from multiple mounting of work. The tailstock also has a 1/2 inch flatted shaft at the end of the quill and will extend 2 1/2 inches to within a quarter inch of the headstock spindle. There are 60 indexing holes on one row on the pulley and twelve on the other row. There is 4 1/2 inches centerline to bed.
There doesn't appear to be room for live center or chuck, but probably a faceplate would mount. No tool rest and not much room for one.
My best guess has been along the line of use on another machine, like an indexing head for drilling or morticing wheel hubs, but then why a V-belt???
Does anyone have any information on this?

Balancing device of some kind?

Not sure of the purpose, but it looks like the headstock and tailstock of a wood lathe on a shortened bed.

Are the 1/2" flatted shafts mounted on Morse tapers? Does the bed look to be a production piece; not shortened?

As a matter of fact, I have the Delta Homecraft lathe you refer to. Their origin at Delta is unmistakable and both bear the Delta manufacturing information. The headstock front bearing on the Homecraft is somewhat larger than on this unknown piece.
It appears to be original as shown. The bed is a heavy gauge steel construction rather than a casting, but shows no signs of having been shortened. It appears the entire spindle is 1/2 inch solid shaft (unless it is bigger where it doesn't show).
The tailstock, likewise, has a 1 inch diameter quill reduced on the end to a 1/2 inch solid shaft with a flat for a screw.

Since Delta primarily made woodworking equipment and this could hold a large pulley or wheel hub over 10 inches in diameter, and the indexing appears to be the main distinguishing feature, I was thinking of drilling or morticing type operations on that kind of part.

Might be a salesman sample.

I have no idea why that isn't a Delta label on the headstock. Other than the 1/2" shaft it appears identical to the early Delta lathes.

I believe the bed is a short bed extension for the older
Delta lathes of this style. The extension could be mounted far down a table to support very long pieces with the tailstock. Delta used a sheet metal bed (like shown) and later a cast iron bed for lathes with these style head and tail stocks.

It's very possible those 1/2" flatted shafts are for mounting face plates, spur centers, live center for the tailstock, etc. Mounting tooling on shafts like this was very common (ie Shopsmith and the like).

I had a lathe like that back in the 60's,but with cast iron bed. It was a Delta,and a perfectly nice lathe.
