I have two 13mm bores to lap and they are made of bronze, any tips on the lap materiel and grades of compound to use.

I have 600 and 1000 grade compound that I can use.

I need to remove as little as possible.

Thats the Badger Jason, and the way I did the job, it turned a few heads as they saw it being done.

A bit of three dimensional thinking!

I remember sometime reading that OSR oil has to be processed to take out any acidity, it is used for foodstuff and mixing with other oils.

Perhaps you had raw OSR and have now reaped the benefit!

Using it must be like 'Frying tonight' and the smell must be like rotting cabbage as it comes from the Brassica type plant family.

The fact that the stain is still there after cleaning means its etched into the metal.

I do find that WD40 leaves a waxy deposit which catches dust quite well if left to dry out!

If you have room under the job for a rotary table you can mount a tool on the rotary table and use that to cut spheres.

I have in fact done this on a milling machine and it works well.

Clive

Thank you Chris, exactly what I wanted.

I am trying to find some Hex. Hd. M2 bolts 20mm long.

I have only found one source in the US, has anyone any other suppliers?

Clive

Thats what 'Chasers' are for, only trouble is I never have the one I need to cut the thread in large diameter components.

I can see the problem with large pitch threads abd clearance would be needed, possibly a three flute tap would be OK.

It is possible to buy a set of circlip pliers that do both internal and external clips and they come with a set of different size pins.

These can be bought from motor tool factors, as you can guess they would be invaluable to a motor mechanic and any other engineer needing circlip pliers.

I think I got mine from Sealey's.

A small planned programme much like an apprentices first six months at the bench, Making a 'Center' finder' for scribing across round materiels, then a pair of 'Parallel' clamps'.

This would entail filing and marking out and drilling and small turning tasks.

Going on from that and make a 'Scribing block and scriber', turning and fitting of parts.

Further projects like making a 'Cylindical square' and even a 'Try Square', all leading up to a model that will give pleasure in making and running.

This 'Programme' would include a list of tools to buy like taps and dies and files and drills, including a 'How to do it' listing.

The tools all helping to make the model as a result of the whole experience.

I bought some reasonable s/steel rods from Noggin ends.

What, like putting pennies on the railway line to see them squashed!

Clive

Joey, probably because the BT gangs and contracters have stopped work for the weekend!

Clive....... Or was that because its stopped raining?

With reference to the speed of this site, I confirm its slooow this afternoon, its raining and everyone is indoors and bored and they are all on the internet hence the internet is slow!

Hello Cornish jack, The BT NTE5 plate is a straight through from the test socket on the original BT socket.

For testing an internet connection it is worth removing the lower part of the BT plate and plugging your ADSL connection straight into the test socket that is then exposed. With no phones or other equipment connected it is a 'Clean' connection.

Now the BT NTE5 plate seperated the ADSL line from the Phono line and has inbuilt filters which means you no longer need filters for any ancillary equipment.

I have no idea if the BT NTE5 plate is similar to the 'I' plate.

All I had was a standard BT box which I replaced.

Best to visit the Kitz site and read up what they say and I can vouch that it works. Again I would add that it helps if you have an insertion tool for placing the wires.

With reference to the bell wire, it is no longer needed with modern electronic phones and can be taken out of its receptacle and coiled back to stop parasitic signals.

Clive

Mick, the plate is a BT NTE5 and is called a Master ADSL Adaptor.

The place to get the new socket is:- www.kitz.co.uk/adsl/socket.htm

Here you will find all the description and the instructions of how to do it, download the instructions (4 pages)

There is a need to disconnect the original BT plate and then put the cables back into the new one.

It is also desirable to disconnect the bell wire. It is all explained in the sheets.

If possible get an insertion tool for the cables.

One thing, is you will need longer screws for re-attaching the new plate, they will need to be about twice the length.

You will also need to put the router close by the socket and then run an Ethernet cable to the location of the PC.

This is not a big job but the cabling /Ethernet run may take you all over the house like mine did.

There has been comment in some of the Computer mags. about this and they say the since BT Infinity has started the bandwidth required has slowed the internet.

Also there is a lot of cable work going on with Fiber Optic and some of these circuits have been redirected while it is carried out.

How true this is I dont know but it makes sense in one way. It all started in mid January with my connection to TalkTalk. when my speed dropped below 1Mbs.

After some discussion on the Talk Talk Forum I replaced my BT input plate with a filtered plate with seperate connections for telephone and internet.

This no longer needs filters for each phone and the internet connection goes straight into the test socket.

My speed jumped to 3.4Mbs but I did have to buy an Ethernet cable to run from the Router to the PC.

I can supply details of these plates if there is any interest. They cost £14 each. The Ethernet cable about £10.

WILD Heerbrugg and now LEICA have always been able to supply theodolites in MILS and GRADS/400.

I have converted many standard 360Deg, instruments for various establishments. Particularly the T2 Theodolite. which is accurate to half a sec. with Auto Collimation. and similarly in the other configurations.

These being mainly used by Military and Shipbuilding. Also used to align aircraft navigation devices and weaponry, ie High Intensity Lights. and in submarines to align torpedo tubes and optical systems. They can be supplied with what is called 'Tight' standing axis so that with a fixed compensator can be used in a right angle mode to transfer lines of sight throughout a vessel.

This mode is when the instrument is fixed to a vertical surface.

Gyro based theodolites such as the ARK1 are usually in deg. and are placed in a special jig prealigned to an airframe and then the aircraft is turned and compass checks carried out.

Maybe now not needed due to Sat. Nav instrumentation.

Regards the Japanese origin I can only go by what I was taught as an apprentice and had no need to research it, only that it existed and how to use it.

Clive

Thank you len, i was aware of the anodising alternatives having for many years done small instrument parts in alu. and other exotics all requiring durable finishes.

Regards the anodising, the hard condition is AA25 for things like window frames and perhaps extreme exposure to weather.

Normal cosmetic anodising is AA5 and for medium conditions AA15.

There is another type of anodising treatment that gives a very shiny finish but the name eludes me at the moment, I know its German name, Eloxiert.(which is of course anodising) but it has a further treatment.

Many years ago I was in Kenya and I had a breakdown with my Opel Kapitan when the camshaft gear stripped its teeth, it was made from Tufnel. (Linen Resin composition)

The replacement gear was made from Aluminium and I had no more trouble from it at all.

Clive

We have worm drive gears on our Theodolites, the gear itself is anti backlash and both the worm and gears are anodised. So obviously they are Aluminium.

They seem to work OK and are able to turn the Theodolite and also the Telescope.
