Boxford Bud Lathe

[Burdekin]

Not sure if allowed to post a for sale link so if not can the mods just delete this. But I thought this might be of interest to someone. It's not mine and I don't know the seller but this looks like a great little lathe setup:

Everything is normally down in Englandshire so good to see a nice bit of kit up here for sale.

That's a lot of money for a Bud. No screw cutting box etc.

I sold my VSL for £1100.

Isn't that a screw cutting box, midleft?

Boxford Lathe models
Model Swing Centre distance Screw cutting Cross-feed Production

The model A had an optional inch or metric screw-cutting gearbox and power cross-feed. The addition of the letters, "UD" to the model letter signifies "Under Drive". Model AUD is a Model A with the Under Drive mount. The four lathes (A,B, C, and T) were dimensionally identical but with different features. Model A was the top of the line with the screw-cutting gearbox. Model B was next with power cross feed and manual gear change for screw cutting. Model C had manual cross-feed and manual gear change for screw cutting. Model T was the Training lathe. The VSL (for late machines, VSL500) was an AUD with infinitely-variable spindle speed control, larger bore through spindle, 'L00' fitting for chucks instead of the threaded fitting of the other models and some other uprated features making it more attractive to industry. The lathes were based on the design of the very successful American South Bend Lathe models.

That's the same designations as the south bend 9 inch on which it was based.

A southbend b went for£ 450 in Darlington earlier in the week. Not often for sale up here. As a price guide it's a tad on the steep side. But a myford ml7 would cost you more. Transportation is the problem with the bigger lathes.
I'd be in the market for it if I had a spare grand kicking about

Scotland. Mid left is the headstock. The gearbox would be under that connected to the lead screw.
Your Denford has a geared headstock which is probably where the confusion is.
To get the correct pitch on screw cutting you either use a set of change wheels or use a gearbox to drive the lead screw. The boxford and south bend Bs use change wheels which need to be changed when a different pith is required. Hence the name. A gearbox makes it quicker to change ratios and pitch of the thread.
Just to complicate further the gearbox on these n when fitted is driven by change wheels that give the gearbox different ranges.
