Disassembly is pretty straight forward but I can't recall the
details. I jest kept taking things off until I had it all apart.

One thing you do need to know is that the screw on the clutch knob is
left hand thread.

Yo D...
The Simplex hangers are 721's and not the same as the DFC
107 hangers, but the boxs interchange, correct-o? Have you
ever seen a set of the 720 legs? I have not. That would look
cool with the flat belt drive.
I have the 107's, but those are the ones I said someone took a
hammer and knocked off the shipper rod mounts...the fools.

Hi Steve

Yes they are for the early simplex drive. They are just like the
ones to my complete set of parts I have.

If anyone is interested in a complete setup for an early Simplex
drive I have it. Motor pulley,large drive pulley, bearings, bearing
standards, and shaft with cone pulley for a 9 inch Series lathe.

I would sell this setup unless someone has the long cast standards
that bolted to a bench and then supported all of this above the

lathe.

Hi Dennis:

I followed your instructions and the spindle came out fine. In fact,
the pulley, bull gear and everything else stayed in place in the
headstock, so I'm just leaving them there for now.Hopefully they will
stay there when I put the spindle back in!

The split collar on the gear end (left side facing headstock) actually
was threaded and turned off the gear end of the spindle--I wasn't
expecting that but it worked out fine so far.

I inspected the spindle and bearing surfaces. Facing the headstock,
the smaller left-hand side bearing surfaces are perfect. The larger,
right-hand side bearing surfaces show what I would estimate to be
galling on no more than 10% of their total surface area.

Also, I checked the felts and they look almost perfect, but I will
replace just to make sure.

While there are lines across the bearing surface on the right-side
bearing surface, there is still a lot of smooth bearing surface left,
so I think I can replace with a newer hardened spindle. What do you think?

Also, do the standard oil types for SB lathes apply to this earlier model?

Thanks,and also thanks very much for those excellent instructions!

Hi Eric

Actually this is a very easy spindle removal.

First locate and loosen the lock screw on the thrust collar on the
left side of the head stock. Then unscrew it and remove it from
the spindle. If it is tight you can take a little small blade screw
driver and insert into the slot or split in the adjusting collar and
then rotate the spindle to take the collar off. Some of the early
lathes did not have a split collar. If your lathe has the solid
collar and its tight use a rubber strap wrench to hold it. Please no
channel locks or pipe wrenches. God I hate people that used these
tools on a machine tool."-((((((

Second you will need to tap the spindle from left to right facing the
head stock. Use a soft face hammer or a block of wood. The spindle
is only being held buy the close fit of the bull gear and its
woodruff key.

Now as you tap the spindle to the right be very careful to not let
the ball thrust bearings drop on the floor. When the bull gear comes
free the spindle will be free to slide out. If you get a little
over exuberant with your tapping on the end of the spindle when the
bull gear comes free the spindle can slide right out unexpectedly.
So just take your time and be gentle with the hammer. You will have
to fist ketch the ball thrust bearings and then the cone pulley. The
last is the bull gear and your home free.

Owe one other thing. The woodruff key on the spindle can damage or
scratch the front bearing journal so be aware of that and not let it
drag across the bearing. AS I start to remove a spindle I like to
look and see were the key is and then rotate the spindle so the key
is at the top this way when the bull gear comes free the key will not
drop down onto the bearing journal.

Now see that was not to hard was it."-))))))

I agree with Jim that any ordinary steel will be just fine for Home
Shop use.
Select a bit with a good surface finish and as thick as can be
slid into the gap.
Preferably you only want the adjusters to take up a few thou of
clearance, less than 10 really. Better to start off a bit to thick
and lap or linish it down to size however if you use a cold worked
material working on the thickness is likely to release stresses and
cause the material to bend. Not good. From preference I use what
is called Gauge Plate in the UK. This is a hardenable steel supplied
in accurate thicknesses. Tougher than ordinary MS but still OK to
work with normal tools having a satin finish ideal for oil retention.
Obviously take pains to do the little extras which make the
difference between OK it works and a real good job (as discussed
recently) including adding a slide lock.
