New Old Lathe

Purchased this today on ebay for the lathe, A boxford multi stop, I picked up a Boxford milling attachment for it last week.

You don't often see these for sale.
 
I wanted an imperial lathe for 1/2 inch unf threads ,but I prefer metric and had purchased a metric top slide at the same time I bought the Boxford AUD, duu I should have paid attension because the preivious owner had converted the lathe to metric bar the gearbox and lead screw etc, yes the power cross feed and dials and top slide are all metric.

so can't the gears be changed for UNF ? as it's the metric equivalent of a 1.27 pitch, maybe just a tooth needs adding somewhere
saying that, after 10 turns the pitch is only out by 0.2mm, might make a tight moderator.

I think it will cut the UNF threads ok as it its just the slides are in metric

Boxford were known for carrying out this conversion for schools when they were changing over to the metric system.
Why they would leave the leadscrew and gearbox as imperial is beyond me, but they did.🤷‍♂️

Use metric transposing gears and your transposing chart. Put your bit on the back side. Then thread in reverse. Thread left to right. Instant reversing motors show their worth here, you must keep your half nuts engaged.

Easier to do all of that, except mount the tool as normal but upside down.
This is what I hope to do, once I make a drawbar to stop the chuck unthreading in reverse (Myford). Needed for any threaded chuck

I have cut left Acme threads in reverse with threaded spindle. Not a problem (for me) if you tighten it well.
Finished tailstock screw has .002 backlash. I nailed it. I don't like the bit upside down :)

Everyone send your air rifle barrels to Mr Si Titor and he can run a tool up the barrel to ream it out to .25 or better still .30 :)

Great bit of kit though.

Engineering skills are becoming more and more a thing of the past, possibly.. like a lot of old school.

Sad but true. ☹️ Manual skills seem to be fading away. Knowledge should outlast the people who carry it, but I'm afraid that except for the few who are interested to learn from the talented and experienced, much practical knowledge will be lost to the past.

I was suposed to be puting this lathe back together but I seem to be taking more of it apart ho-hum.

I have done that with several lathes, but putting them back together with the confidence everything is correct is the satisfaction it gives you.
 
Modern society is just throw it away and buy another.. all old school trades and skills are in decline, one would think. :( Nothing is made in the UK, or very little compared to decades ago...
 
I have still not got this lathe back together, the headstock has 'some' body filler on it at the moment as i sanded off a lot of the paint and filler as it was shrinking and crazing up and the castings are a bit rough without filler.

I have been stripping and painting parts here is the 4 position carriage stop in machine green.
