Boxford help please Bob Minchin 05-02-2008

 Hi,

I have to move a boxford lathe soon. I only have a photo of it so far. I
think it is BUD mk2 model with a lever near the changewheel cover for
changing speeds. The symbol on the front shows a cone pulley.
So if it is a belt drive how does the speed change mechanism work.
Is it like a deraillier bike gear system?
I might have to take the lathe off the stand/motor to shift it and
wonder if this is easy or best left as a single unit.
Any ideas on how much it weighs - it is the non screwcutting gearbox model.

Bob Hi,

Google groups is currently refusing to allow me to post an answer so I
will try here. Apologies to all if it appears a few times.

The lever near the changewheel cover is in fact the leadscrew reverse.
Spindle speed is changed in the left hand (from front) cabinet below the
headstock where you will find a belt tension release lever and the cone
pully that the plate shows. Speed is just changed by moving the belt up
and down the pully block as per normal. That plate is merely telling you
what spindle speeds you will get in each pully position with direct
drive or backgear which is selected (A or B) with the lever on the very
top of the headstock. Confusing until you see the lathe then very
simple.

You can take the lathe off the stand easily enough as the drive belt
which goes through the bottom of the headstock into the stand and the
layshaft is a link type and can be broken. It can be a bit of a pain to
re thread though on re-assembly. I moved mine in one piece as I felt
that was easier, total weight for a Mk2 AUD is a little under 580lbs or
265Kgs (ish) so a BUD will be about 40lbs less. I moved mine with a 1
ton cheapo engine crane but remember that it is top heavy and needs good
support when moving if it is not to topple over. They tell me that 4 men
can move one complete but they will all be far stronger than I. There
are two through holes at the top of the cabinet that you can pass a
couple of bars through and these provide lifting points.

If you haven't found it yet, join this group:

http://groups.yahoo.com/group/BoxfordLathe-UserGroup/

Look in the links section and you will find a link to an on line PDF
copy of the "Know your Lathe" book which is in fact the Boxford manual.
It is about 8Mbs though so you need a reasonable internet connection. If
you have any problems downloading send me an e-mail and I will reply
with a copy of the file.

Hope this helps, apologies for the somewhat rushed response.

Best regards

Keith

It isn't a good idea to break the lathe from the stand. Apparently
(from the manual, lathes.co.uk etc) they used a bedding material that
can make getting the two apart quite difficult and getting the two back
together without distorting the lathe even more difficult.

I moved three by sticking bars through the holes just under the splash
plate and slinging them from a 2 ton engine crane (in the half ton
mode). No problem unless you want to raise it high.

on the stand, the load is unstable, so you need ratchet straps or a
knowledge of how to tension roped loads.

Thanks RSSS
Useful tip. I was considering splitting it to reduce weight for man
handling. I think now I'll shift it on rollers and use a tail lift
equipped vehicle.
Cheers

Bob

When I had a Boxford BUD, some years ago now, three of us manhandled
it off the trailer & into position. Likelwise a few years later when I
sold it. As far as I remember we had a bar across under the bed so two
people could lift, or almost lift, one end.
