Hard to imagine that you will find another except from the same equipment...I can knock you one up if you cant ?

So its 6mm 2mm pitch twin start?

I have another newly bought gravity clock but unlike the one that Micheal has I just cant stop this one..it seems VERY sensitive to the position of the pendulum ball and the fine adjustment screw however

I’m just at the moment printing some faces up on glass blanks

I was just wondering whether the individual items would cool more between having new layers added making the layers not stick as well if done one at at time

Got my printer up and running and churning out widgets from thingiverse  by the bucket load very pleased so far however when i want to make 4 identical prints should i do them one at a time or all 4 at once?

Or nutlink belting

Sometimes called Brahmer belting i may have spelling wrong though

What did people think of it? The programme that is

I would say that they are impossible to use as they are as a normal tap

I have only used them for cleaning up after single point cutting on the lathe

Just pull or use a little lever...hold the minute hand and one or the other will come off hopefully the knob

Fiona

To get the case off to see whats rattling

Take the hand knob off the rear of the spindle at the back of the case

Remove the finials of the top of the columns

Take the cross piece off

then the whole clock will lift of the racks

then remove the 2 screws next to the hand knob (now removed)

Then the back of the case will come off revealing the mechanism.

Just get any led operated light and put a switch on the door to hold it off when shut...so when the door is open the light is on...battery life not so important now.

And now ...what software do i need

Ian

Oldiron. Have a look at readly its an online magazine subscription service with loads of magazines at a all you can read price of £8 per month 4 machines /people

It doesn’t have much in theway of model engineering mags but good selection otherwise and stops the house getting full of dead trees editions (and i say that as someone in the print industry)

They do trials too at a lower cost to start

Much recommended from this household

Thanks for that Colin duly bought with auto levelling too

Can anyone supply a link to a 3d printer on ebay in the uk that’s good for a beginner to dip toes into 3d printing?

I have a 20% off voucher that’s only valid today

If the cheapies cover the sizes you want they will do....these are just for tpi and pitch you want them for?

In the independent today

What shape is the universe?

The Universe is what is known as a hypersphere. A hypersphere is almost impossible to visualise, as it is a four-dimensional sphere – it alters with time. However, you can use the analogy of an onion to describe it quite well. Imagine the universe as it is now, this very instant, to be the outside layer of an onion. If you could look out into the universe as it is now, you would be looking around this shell. If you could look far enough, you would look right round it and see the back of your head.

But we cannot look at the universe at this very instant, because as we look out we are looking back in time. You can imagine that everything you are looking at that is at the same distance – say, five light years away – is on the same shell of the onion. The further away you look, the closer you are looking to the centre of the onion. These layers do not exist in this state any more (in terms of place or appearance) as they have moved (with the expansion of the Universe) since the light left them, but this is how we see them. You cannot travel from one side of the outer sphere (the universe as it is now) to the other side through the centre, as the centre is not just empty space; there is no space. You can travel only around the shell itself, as this is where the space exists. Well, we said it was hard to visualise.

I’ve just done some testing on the sample of brass that i’m Using

I remembered that i have a 20 degree pointy tool so i measured the original to a set of co-ordinates from base and diameters and using the dro just plunged in to get the diameters and then a quick smooth with emery and a scotbrite pad and job looks good

The originals were brass just heavily tarnished

How would you go about making 2 matching versions of this finial?

I have turned pieces threaded the base so i can hold it in a fixture but how on earth do i turn the small features?...hand held gravers perhaps like woodturning

With the advent of fly by wire systems they may be making a comeback my wife's B class mercedes has a stalk for the gear selection (P,R,N,D )as well as flappy paddles
