The taper rollor bearing ML10's are Greased!

mike, you have two guns one for the grease and one for oil.
The grease I use is ordinary grease bought from halfords, LM I think it is, and the oil is Tonna oil.
The headstock bearings I fill with grease a couple of times a year, I clean up around the brgs. and then pump in the grease until it shows at the mandrel gap.
I then clean up all the expelled grease and then use the oil gun to oil the other points on the ML10 like the tailstock shaft and oil the leadscrew brgs.
Very simple really.

Les, you say there is no way you can report a fault on Talktalk. Yes, there is.

Thread: Chuck locking ring.
09/12/2011 10:32:58
It's a standard fitting on all Schaublin chucks and has worked fine on all four of the Schaublin lathes I used.
When I ordered a new chuck for a Schaublin lathe it came with ring and backplate complete. I did not have to machine or develop it at all.
It is a viable means of locking the backplate to the mandrel, unless someone comes up with a better one for a screwed chuck.
I have used the bolt on type chucks and I prefer the locking ring type much better.
Chucks can be quite heavy and awkward to lift away.

Ian, the bore of the ring is plain and the small step is just 1.5 x 1.5mm to clear the machining fillet in the corner of the back plate where the round nose tool has machined it. It could be a large chamfer if that is easier.
The ring is the full width of the seat on the chuck back plate and does not touch the mandrel.
The concept is that it clamps the back plate down onto the mandrel plain portion which seems adequte to lock the ring tight.
I will take another photo dismantled shortly, and post it for you.
Am suffering the after effects of a bout of Norwalk Virus, both wife and self, so its a double whammy.

Thread: Myford / RDG
08/12/2011 21:25:31
What I found with my Myford oilgun was that the rubber sealing disc would bell up under pressure, pulling away from the edge seating and then leak!
Made a bigger dia. seal from some Vitax and all OK.
 
Reading about RDG/Myford making a new lathe, I wonder if it will be in the same shape and format or maybe modernised to facilitate machining?
I know they have all the patterns etc.
The Myford is an outdated design and a new modular lathe would be a great asset to the engineering fraternity.
 
Discuss.

Thread: Chuck locking ring.
08/12/2011 21:19:48
Ian, its purely compression on the machined seat of the back plate, all the time I have used one I have never had a chuck shift.
It will clamp on the parallel portion at the end of the thread.
The ring is76mm dia, is 12.95 wide, the bore is 49.99 dia.
It has a step on one face to clear the fillet on the back plate.
Slots are 10mm deep at 90deg and the 4th one cut thro. The clamp screw is M6 Skt hd.
 
Hopefuly you would have enough meat on the backplate to fit such a ring?

Today the connection to the Forum is very slow and takes agaes to cnnect and load, this coincides with the schools shutting for the day!
Must be all the kids hogging whats left of the bandwidth.
Also late at night the big shops locally download their data and it is hard to get a connection again.
We are 7 km from the exchange and its never been any different.

Thread: Chuck locking ring.
08/12/2011 17:46:23
I have placed a photo in my collection of a chuck with a locking ring.
This is the method used by Schaublin to stop screwed chucks from unscrewing in reverse.
The back plate is machined to accept the ring and I do believe the rings are obtainable commercially but have not found a source.

Hello Bob, How do they justify that price indeed, must think it's a rarity!

Thread: Why are milling machines so b****y expensive
04/12/2011 17:14:22
Having worked on Schaublin milling machines in my working life I just checked to see if they were available, No, they have ceased trading and do not make them anymore.
They were expensive but excellent machines.
I checked some of the secondhand sites and a few came up in Switzerland but they never give the prices. One place has dozens for sale!
A Schaublin 13 mill recently sold for £1375 here in the UK.
It seems they are like hens teeth in the UK. hard to come by.
I will have to lower my sights I think.

Brian, certainly turn them between centers, this will help you to turn the flange radii on the wheels. You will be able to turn the wheel assembly as one unit.
 
MGJ, At the moment it is in the building stage and until I can afford a boiler I will just potter along on the smaller bits and the cab.
You can see from, 'My photos' the point I have reached, I have made the smoke box and some parts of the regulator (very fiddly) and will start on cutting out the cab.

Thread: Interpreting drawing?
30/11/2011 17:54:00
The exploded view shows the plate in its correct orientation with the offset hole in the upper face. ergo, the drawing is in fact upside down and the cross section shows the hidden detail with the sloping hole downwards towards the central hole.
The Isometric drawing shows the under face view.
This is not 1st angle nor 3rd angle but just a detail drawing with a cross section.
This is nearly always included as a seperate sheet or a boxed drawing on the main drawing.

I have been unable to locate the latest issue of Model Engineer workshop at W H Smith where I usually buy it.
That is the Hempstead branch and the Chatham branch here in Kent.
Has there been a problem with the supply to Smiths of this issue?
They stock the latest issue of Model Engineer.

Thread: Tipped Tools
30/11/2011 12:23:05
Wolfie, forget the tipped tools for the moment, when working the lathe you always need tools of a certain shape.
It would be better to get yourself a decent two wheel grinder and then you can shape you HSS blanks as you want them.
Also get a green grit wheel for carbide tools later.
The best boring tools are of the 'Bar' type and sometimes have removable heads.
You will need a 'V' block to clamp them in or a block with a slot to clamp them.

I used ground mild steel on my Evening Star and its got five axles! It all runs very nicely with no high spots at all.

Thread: Making darts
27/11/2011 19:21:18
I at one time had to machine some Tungsten counter wieghts for balancing telescope attachments to telescopes that had a 360 deg. rotation.
I found them extremely tough! I used 3 fluted solid carbide cutters and they 'Grunted' a bit.
Luckily I only had two to do as it was hard work on the mill.
I set them up on a rotary table and they had to be machined in an arc to clear the projections they would travel over.
The cuts were very light and repetative to complete the job.
At that time this type of counterwieght was very common on theodolites to balance the wieght of the Distance Measuring device attached to the top of the telescope.
Now the EDM is incorporated into the telescope and counterbalances are no longer needed.

Thread: Motor Switches
25/11/2011 14:03:36
Another thought is that as its a fret saw that the switch has a build up of dust on the contacts or the moving parts, If you can try blowing it out with compressed air and see if it makes a difference.
My small bandsaw has the same problem which I correct using a contact cleaner and it clears it of wood dust!

Thread: Salvage from defunct inkjet printer

Going back to the seven sheds, my Bro. is/was a Vehicle engineer and likes pottering about with cars and lawnmowers and cultivators so goes to boot fairs and buys up old engines to replace duff ones.
He is also given stuff like cement mixers and old ovens and lengths of wood, all now riddled with woodworm.
It all gets stored and forgotten and I joke with my Sister in Law that they will need two ten ton lorries to clear it all.
He never disposes of the cars he has had and dumps them in the orchard we own. This is where they go rotten rusty and I complain but to no avail.
Dont mention old baths as they are used to collect rain water off the roofs of sheds to irrigate the garden.
I do despair sometimes, ask for something and a long search begins and stuff gets pulled out with the comment, 'I was looking for that last week'.
At 82 years of age he must stop sometime surely? I do not think I want the job of disposing of it when the time comes.
