Hello welcome to enots engineering i'm Alan
in today's video we're looking at the Boxford and looking at what all the levers and knobs do
on the machine now when i first had a lathe and wasn't sure what the parts
were called I used to think of it as a horse you have the headstock the tail stock and the saddle
that might help you remember some of the parts let's go into the workshop and have a look
this is the boxford lathe what i want to do is explain what the levers and pulleys and buttons do
and how it works we'll start with the headstock
this is the headstock and that holds the chuck on the main spindle
so we'll start at the top here this lever engages the back gear
and what that does is slows the chuck down
depending on what which position the lever is on this chart if you put it in the a position
which is there that would be running at a speed of 1400 rpm so if you move the lever
working further down this hole is an access hole so you can put oil can in there and there is a oil
hole right inside you have to turn the spindle around to get it lined up with
this hole and then you can put the oil. these two are grease nipples to get grease to the bearings
some have caps where you put grease in a cap and it goes into the bearings
so if we move down this is a spindle lock so you turn
you can turn the chuck by hand without the lock and then if you engage the lock you can use that
so it holds the spindle still so you can take the chuck off now it is possible that that spin
that spindle lock will stick so before you put any power in the motor on make sure that the spindle
lock is out and by pushing the chuck back slightly it will spring out sometimes it will stick so
what have you got now we've got this lever here which if you pull it in move it down move it out
and that has changed the direction of the lead screw through the gears inside
so at the end of the headstock we have the gearbox and there's a chart that comes with the boxes
lathe i'm not going to go into thread cutting and gear changing you you rearrange the gears
to suit the thread that you want to cut it comes with another a lot of gears so you can
swap these three main gears over on this one these are fixed these are for adjusting the
forward and reverse of the lead screw
so if you want to cut a left or right hand thread you just re reverse it or run it normal and
depending on the layout of gears that you have
will cut the pitch that you need if this is a metric lathe so if you want to cut an imperial
thread on this you need to replace one of the gears depends on what thread you're cutting
with the large conversion gear so unless you're going to cut a lot of in my case it
would be imperial threads if you've got you've got an imperial lathe it'd be metric threads
this is interlocked so it won't your lathe won't start until
the doors closed and on the back here you got the chart with the different
gear positions so by altering this lever you will then alter
the lead screw not the chuck just the lead screw and the gears from the center of the spindle that
are in the train that drives this you'll reverse them or put them forward and that will have the
effect of the travis moving towards the chuck or away from the chuck or even if you have the
top slide it will have it going backwards to the back or come to the front
we'll now go over to the the bed of the lathe work towards the tail stock
okay coming down on this side this is your lead screw
here it goes into the gear box and there's an oil oil nipple there to put the oil into this bush
the bed of the lathe goes from the end of the headstock to the far end of the lathe
and they'll be different lengths depending on what lathe you've got and that guides the saddle
and holds the lead screw in position so coming on to this part
now this is the bed of the lathe which goes along to the end and on the bed is the saddle
below the top slide is the engagement lever for the travis that lifts up engages on the lead screw
so just engages the lead screw disconnects the lead screw next to that is this lever
you pull the plunger out and you can move it down or up or in the middle
so the the lever when it's engaged we'll let the travis move and you see its moving along
to get the travis to work on the top slide you have to make sure that the
lever here is not engaged on the lead screw let's move up to the
tool post
so on here
we have the compound slide
which can move backwards and forwards by hand and you can rotate this is a protractor
with degree markings around there
so you can rotate this at any angle up to 90 degrees and then on top of that is your tool post
center bolt goes through onto the t-nut underneath so you can move the tool post whenever you wish
and also you have this spanner that goes on the tool holder
so you can take the
tool holder off and change it for another one
and then tie it up with the spanner again and your tool goes in here this adjusts the height
okay that's a saddle now this front part with all the handles and knobs on is called the apron
so let's move back to the tail stock this is the tail stock you have a lever at the back
under that and it you can push the tail stock backwards and forwards along the bed
and it locks it in the position that you want this is the spindle lock it locks this
spindle from moving in and out when you've got the position you want
an oiler here this is the barrel push there with a handle on the end and you can turn it in and out
and inside there is a taper in this case it's a number two morse taper
and you can fit chucks centers and other items in there
then the cast in here now on this one i have a grub screw at the front and back so i can move
the center line of the tail stock towards you or away which is used for useful for taper turning
further down is the other end of the lead screw
with a block that holds it in position and another oiler there
and then if we go down to the bottom this is your on off switch for the power switch lathe on
this is the transformer for your low volt light this is your your power for
the motor for the headstock so you've got forward reverse top and bottoms off
oh well that's it for today hope you enjoyed it
hope it was useful and we'll see you next time on enots engineering
