hello welcome to enots engineering i'mA lan in today's video we're going over to my brother's
workshop to have a look at some modifications he's making to his lathe let's see what he's doing
this is my boxford lathe and one of the issues i have with it
is getting oil into the right parts where it's required
one example is the saddle you'll find that there's no way of getting oil between the wipers
on the ways
so i feel that there should be another oiler or four to be precise
that allows you place somewhere about here that feeds straight in
to this the cavity will be presented between the saddle and the ways on on the top of this
the v-section and same with this side i think there should be another isla somewhere here so
when you inject oil it gets right between the two wipes and it's it's where it needs to be
at the moment the only way of lubricating this is to lubricate outside the wipes front and back
and then you notice that when you move the saddle up and down
the materials that's been trapped by the wipes doing the job it's you can see where it shows
up bits of brass particles i'll show you as an example so if we'll just wind this back slightly
you can see a little bit there and you so you'd lubricate
say here and try and work it in past the wipes
and then what you find
if i zoom in
you'll find all these particles from machining that have been trapped on the wipe and you feel
like you're forcing those past the wipe so god knows what's getting past the wipe
into the mating surfaces where you don't want any contamination and i think if we had a hole
and an oiler fitted in here when we inject oil it's going to be between the wipes
and then it's going to try and force these particles out rather than force them in
so what i'm going to do is remove the saddle
and investigate the possibility of inserting some oilers
i have two sizes a brass six millimeter one and a tin
quarter inch one which is what is originally installed under the in all other areas of the
lathe so i might go with this one um as it's it matches other parts of the lathe where
there are oilers so this is this is a six mil and this is a quarter inch
as this is an imperial lathe i shall be going with the quarter inch oiler
so let's get this mounting i'll start off by removing the glass digital scales
the dismantling section i've speeded up i'm just removing the retaining bolts for the glass scales
read head and i'll then slide out a packing spacer then i'm going to undo the grub screws that hold
the glass scales in position and put those to one side safely just clean off some swarf
then i'm slacking in the grub screws to remove the tool post slide
this section is just a bump stop i've put in to protect the glass scales
from being smashed into by the tail stock
i'm going to remove the lock-in screw for the saddle and nut
and then it will remove the saddle itself and take it to the bench it should lift off now
see some of the the swarf talking about so the saddle's just the end of it was just here
the front of it and the back cause i've just had a view of this shot but in between so in between the
wipers the wipes the felt wipes we have some swarf in here and and that's what i don't want so i'd
sooner oil go in between the wipes and wash any swarf out rather rather than oil
each side of the wipe and encourage swarf to come in
this this is what the angles are going to look like so say a small hole
just probably an eighth of an inch maybe smaller this way
and a quarter inch diameter hole this way this is one of the oilers that i mentioned earlier on
that was leaking and so i'm going to replace this the easiest way i find to remove of removing these
is with some easy outs they've got this type of easy out and this type i can use with a
a tap wrench i'll try this one it means destroying this totally but it leaks anyway
so it's finished i'll just rotate this onto each side so you can see better
so i'll try this type first
yep that's coming out that's gripped it
let's get some pliers remove that from the easy out
let's say it destroys it so there's the ball bearing there and the springs probably all
collapsed inside but the important thing is to extract it without damaging the casting
so i'll just clean that up there now i found um a small socket that just sits nicely
without pushing onto the ball bearing it just sits nicely over the over the top surface of this
and it seems to be applying the pressure we're in line with the u
the metal outer casing which is what we want we're going to be caving the center in
we're going to be caving the outside so we need the pressure just where it needs to be
might be best to make a brass dolly actually to do this but i'll see i'll get on with this
a little bit of oil in the hole just around here just to help
help it go in
just a couple of taps make sure it's lined up all right
okay i've totally wrecked that one so i'll extract that one i'll make a brass die
that sits uniformly across the surface
okay so i've drilled a pilot hole then a quarter inch diameter hole
to match this angle on this blank here from underneath i've drilled a 1 16th hole
but you can see that there in the bottom 1 16th hole underneath straight in the center of the v
and they both luckily they both meet up
slight chamfer on there so that's a the second 1 16th hole drilled
i'm going to turn it around now and drill the quarter inch
down to hole we'll start with the center drill
now i'm going with a one-eighth drill
okay so i've drilled the quarter of an inch hole to the deep enough for the oiler to go in
and you can just see the the other size was it the 1 16th hole just at the bottom of that hole
okay there we have it the two oilers are pressed in
and i've just charged it with some oil to make sure he does come through the other side
okay i've speeded up the reassembly and here you can see i'm inserting the cross feed screw
and just with the two retaining screws going in
just remove some any dirt that's been picked up on there before a slide
across me across sliding into position
some oil being put on before i put the saddle into position
just inserting the saddle locking nut
the cabinet bolts will go through to hold the apron in position
just ensure we've got freedom the realignment's okay
and the gibbs stripper to go on the back
of the saddle stop it lifting up
just trying to tighten those two cap head bolts that hold the gib strip in the back
again checking that it's not too tight
carefully moving the glass read head into position
i'm just installing the protection strip there that stops the drop screws digging into the
cross slide of the lathe
just sliding the scale into position putting the packing back in
that holds the read head just at the correct height
both the reed heads will need setting up with the plastic space space in
retainers that came with the glass scales
just slides between the reed head and the glass scale itself maintains the correct distance
so just tighten those up for now put the tool post slide back on
and there we have it
all back together as you can see the lathe is now fully assembled showing the two button oilers
thank you for watching and i hope you found this useful
