Found an interesting link about the old lifts raised by water pressure:Water Powered Lifts : Nostalgia Board - Melbourne, Victorian & Australian Architecture Topics
Peter

As usual, what seems to be a new idea, has been done before. The earliest type of lift in Melbourne was controlled by water pressure. Long before cables and motors.

Refers to the larger Sheraton lathes. Not quite sure of the date, but the chuck mounts are described as D1 camlock, so must be later models.
Peter

That sounds great Ken. In my case, I obtained the machine for the cost of scrap metal. Originally intended to make this into a wood lathe. It was not really worth restoring to a metal lathe, besides...

I think I have a model 16, in parts. The main bed is used to support a wood lathe, the rest is in storage. This has a later headstock fitted. Previously used as a lathe to repair and machine drum...

Here is a parts manual for the conquest.

I think its a bit subjective to rate any of the better machinery, it's "what it can allow you to do" that is important. It will be accurate enough for most requirements (within its size), but keep in...

The headstock was found to be in pristine condition, as the photo's show. I did not need to touch the gearbox or the spindle bearings, simply changed the oil.
If you look at the design of the...

Having recently restored my conquest, I inspected inside the headstock to check the condition of the gears and any wear. The photos show a well designed and solidly constucted headstock. Three of the...

This what I did with a surplas old lathe stand.
With the timber lathe mounted, dampens the vibration to a very low amount.
I coud imagine a converted headstock using ball bearings and retaining...

Looks like you are winning! Yes, the spindle should come out quite easily. The resistance will be the fit on the bull gear and the inner bearings. I think I used a copper faced mallet without much...

The method you suggested is correct "in theory". The keyway should only engage the bull gear. The pulley set may have been deprived of lubrication and seized on the spindle. Suggest a good soaking of...

All I did was to remove the spindle assembly, leaving the outer races intact, clean the bearings and replace. From memory, the inner bearing needed to be gently tapped back to get the correct...

These "Norman patent" type toolpost holders have been around since the the early 1900's.
See link: An old-design QCTP for the mini-lathe
I am always surprised that many good designs have been...

Sorry, I see what you mean.
To be honest, I have had no need to remove these gears. Probably because it was difficult to remove.
Assuming there are no grub screws or locating pins, the main pin is...

Not sure about the latter metric gearbox, but check these shots to see if they are similar:

Al,
Sorry, the colour should be SKY GREY.
Peter

I was able to get any of the oilers from "Pertek", bring along a sample to show them.
The paint I used was this:::: White Knight Paints
The colour I used was "Sky Blue". I tried using the spray,...

Sheraton use 20 deg.

When you remove the handle, there should be a pin. Leave it alone as it clears the bush.
See photo.
Peter
PS I would unscrew old nut by tapping with a pin punch, then remake a new one.

Anybody have any knowledge of this make of lathe?
Appears to be a southbend clone, Parkanson brand made by Servian machine tools....

I know what you mean. A big benefit of having kids in this age, is keeping up with technology. The following would not be working at home without their help: computer, mobile phones, TV, digital TV,...

Daniel,
This is exactly the sort of information we need to get a history of these lathes.
The brass plate probably suggests an earlier model, the stamped number is an open question.
Has your lathe...

Try looking at the lathe bed to the tailstock end.
Like in this photo.
Peter

Hi John,
Have you stripped the headstock down yet to find where the wear is?
I am a bit dubious about trying to bush the headstock. The spindle would also have considerable wear if it is that bad....

Guys, I would be interested to know if the spindle shaft is the same as my 9" Sheraton with the spiral machining in the casting.
Refer to thread: Hercus, etc Model data, post #7.
I know this one...

Hi Danny,
Are you able to post in some photos? It will be easy to determine from a headstock photo.
The serial number is on the bed at the tailstock end, between the v ways at the back.
I don't...

Hi Daniel,
I certainly dabble with the Sheraton lathes. I can tell you that it is possible to get
repaired or good secondhand parts to repair the headstock gears.
Is the lathe a plain bearing or...

Jack,
Don't tell anyone, but I got mine from Hairyforbes.
The prices are very reasonable at the moment:

Considering the list prices from...

I have swapped a number of motors for pedestal drills. The most drama I find is the shaft diameter to pulley size. Most new motors are based on a metric frame, and the diameter also depends on the...

Yes, thats right. They have a wider section pulley.
The downside from this arrangement, is the section left is very thin, and the lip is liable to crack.
Peter

See photos:

Some details that may not show up on later models. I have photos of the outside
but there are also notable differences/changes inside.
The photos show:
The hex nut shape to both tailstock and...

I have to agree with Pipeclay here.
There seems to be a resistance to using carbide tooling because of bad experiences the earlier days.
Because of later advanced designs, I can use a lapped...

Just to add to the info, the Sheraton clone has 38 teeth, 5/8" long gear teeth, is 16DP at 20 deg, overall length is 4-1/8".
As I thought they were inter changeable, can someone confirm the length...

Pipeclay is correct, the Hercus is on the right.
See how the sheraton gear, cut at 20.0 to the left, has a less steep flank and comes to almost a point.
The "said" advantage of 20.0 gears compared...

Even though the range of Hercus models and similar Sheraton 9" lathes have similar leadscrews for the slides, same diameters, lengths etc. There is at least three different ways to key the handle to...

I think the subject of "what oil is the best" has been dealt with on numerous threads.
The most suitable viscosity, is the grade that has been allowed for in the design of the bearing itself. Given...

Nor quite obvious, but shown side by side is the different teeth angles
cut on the change gears.
The Hercus is 14.5, the Sheraton is 20.0 degrees.
Both are 18 DP.
They are interchangeable, (not...

Ian,
Good idea.
I have a copy with the quantity made per year.
Anyone got a list of the Sheraton?
Peter

From the outside, the plain bearing model headstock of the Hercus looks the same as the Sheraton. The bull gear, thrust bearing and pulley (but not belt size) are interchangeable.
However inside the...

David,
The oil you are using is too heavy, try an ISO 32 hydraulic grade oil. This equates to roughly a 15 SAE engine oil and doesn't have other nasty additives in it. OK, it might not be the...

Ausdag,
The photo shows a plain bearing headstock.
The side play of the bearings I have been told is .001". Measure this with gauge and a heavy rod slid into the spindle to give a bit of leverage. ...

For some time now, I have been thinking about the information regarding various model changes of the Hercus and similar clones like Sheraton. There seems to be a lot of incidental facts that are...

Now that the blood pressure of this thread has resumed back to normal, I have
been thinking about the information regarding various model changes of the Hercus and similar clones like Sheraton....

Hi Ken,
The screw in the centre of the clutch knob is LEFT HANDED THREAD.
The half nut handle is retained by a grub screw with pressure spring from underneath.
The studs that hold the rack pinion...

Thanks Neks,
It is not a big deal to strip the gearbox, good idea to remove grit etc.
The biggest problem I experienced, was when the tapered pin through the gear and cone shaft refused to move. I...

3. Tumbler shaft assembly.
Again this uses a taper pin, simply to retain the shaft from sliding out. As it is not under any shear load, replace as always with restraint.

2. Drive shaft assembly.
Straight forward to fit.

1. Cone shaft assembly.
Straight forward to replace, just requires some gentle tapping sometimes with a soft face hammer to fit the fixed gears.
Be careful to line up the taper pin position, after...
