Being a beginner & at the risk of looking a total idiot - does the tungsten have to be "pure".

Surely the SG will not vary much if it is mixed with a few contaminating metals. I ask because I wonder why you could not save a fortune by just buying some tungsten fishing weights & turning those. The impurities would probably make them softer & the cost would be softer on the pocket. I cannot imagine the specific gravity being that much different, or is it? Or would the balance between 2 different weights be the problem?

Presumably whilst soaping the nether regions

You would hate dying young a lot more

I used to order timber by the "standard" & used that measurement until I sold up in 1999. It was about 164 cubic ft

I seem to recall my father buying log sawn timber using a " Hopus" measurement but it was so long ago I cannot recall if it was tons or Ft 3

And can you tell us how thick these sheets were?

I notice the link shows a sketch of a hypobolic perabola. If you want to see one in the flesh take a drive up the A1. It started out as a garage forecourt roof then became a Wimpey bar or something. Not sure what it is now but it was there when I went to Doncaster MEX the other Friday.

I always remember it because our lecturer had great pride in explaining that description when asked  & I was able to tell my father- who replied with "Oh!  right !"- as we drove past one day.        What a waste of education !!!!!

& did you lay them on the ground & insert pins in the small holes in the handles or did you tension them with weights across tripods with plum bobs hanging down to give the distances

All done to bore the pants off us students in Hylands Park Chelmsford- I still have a very accurate survey of just one little section 50 years later. God knows why but I could not bear to chuck my student notes away after spending so many hours writing them

I think that you are wrong. depending on the values inserted in the formulae the curve transposed into the graph can be changed. it can have a steeply curved bottom section or a fairly flat bottom section with sharply curved shoulders. (The points of suspension being the same distance apart)

I accept that a particular value can be inserted to match the curve of the chain/ rope etc in question but as the curve of the formulae can be altered to give a distorted curve then the definition cannot be a true definition of a catinery. I am not aware of any chain/rope etc that will give a distorted curve unless it has a core or outer cover that might change the stresses in the material ( perhaps lead cored rope etc but we are not talking about special purpose ropes )

A bit like saying that Pythagoras theory can be proven by measuring the area of squares on the hypotenuse & comparing to the sum of the squares on the other 2 sides. It may be true but it is not the scientific method for proving the theory.

If it was free hanging it would be vertical & fixed one end only. By virtue of the fact it is between 2 points it is under tension due to the forces of gravity, so i cannot completely agree with your theory as any cable/chain/rope/wire between 2 points will be under tension even if a varying degree of slack is allowed

I am recovering from a weeks holiday.

A month ago i gave a talk on navigation to our yacht club to persuade some of the sailors to join me in a cruise to Boulogne for a 4 day cruise.Some of the members ( based on the River Blackwater in Essex) think that Bradwell power station, at the mouth of the river,  is like the moon- They have never seen the other side

Upshot was that 10 put their names down, but by the time their uncle's neighbour's dog was taken ill & the library book had to go back we were down to 5

But no worries it ended up in a trip to Dover, Boulogne ( stopped a day) Ramsgate & home. Spent a fortune in wine & merry making. Had a boat break down & get towed in to Boulogne. I had to be hauled 15 metres up my mast to everyone's enjoyment but we all made it home safe.

Here my son is filming me, filming him. The London Array wind farm in the background.

So now I have started thinking about the hand pump for my PYRTE traction engine with some of the bits purchased from the Doncaster exhibition last week.

Wish I could get some decent drawings -- Anyone able to guide me to a free simple one for a 12 inch X 4inch diam boiler running at 45lbs PSI for side mounting in the side of the tender. Instructions with the details are Carp

In my opinion - for what t is worth- the learning curve is too great for a one off such as a house. In my business ( I started with Autocad version 6) i constructed thousands of templates & could cut & paste pre drawn parts to make a drawing of a project thus saving hours. I needed a knowledge of how to stretch scale , group move copy etc & draw arrays do dimensions etc at speed without thinking. Even simple things like drawing a cavity wall with a window in it can take ages or a concrete foundation with a drain passing through it can take a while, then there is the text that has to be scaled to fit.

Heating & electrical systems need to be layered in.

if you pick a particular package find one with a good backup of construction templates to save drawing things like stairs & windows, frames & doors

Really you would be better with a T square & a roll of tracing paper then send the lot to timber frame manufacturer to design the complete package properly

That is how I did the last house I built for myself- Did 2 for myself

Doncaster gets a plus from me & i drove 183 miles each way to get there

bought some metal but really just enjoyed the models & admired the skills

Could be arranged !!!!

With the greatest of respect i get the impression the programme will not actually start de activating anything until one commits to paying at the end of the 30 day period. True one can opt out at 30 days but as I will be somewhere between Bradwell& the Bay of Biscay in 30 days on my boat i will not be able to cancel the 30 day option. Waiting for the price to " come down" further suggests that you must have had some contact or approach trying to get you to contribute, so I do not buy into your comment that you have not had adverts. ( I do accept that you may not have been "bombarded "(. As for downloading from the wrong site- Well I can only down load from a site that looks correct & how would i know that it was not the correct one? True I may have been conned but such is life.

Update- It appears today to be scanning the system & now working which it certainly was not doing yesterday. Is there some delay built in? Furthermore, I have had only one further payment request since this morning, Although I have only re booted once & run the scan once today-- All very odd.

Thanks

I made the mistake of installing avast having read that it was free. Unfortunately it is not. Once installed it informs one of a number of possible errors on the computer, as do many such programes. It then says that the user can have 30 day free trial provided one hands over credit card details. if one does not like it one can cancel on 30 days as it will send a reminder before it cashes the card value.

For me that is a no no as I will be on my boat then & not have access to the internet so would be lumbered. hence I have not taken up the offer. trouble is that now I am bombarded with reminders to pay.

I now have to work out how to get rid of it. Hopefully there is an uninstaller but like many things it will probably leave bits of rubbish behind. So beware of this con "free offer"

having had a joinery business that did lots of conservation work for English Heritage etc I think one needs to comment on the other side.

I have seen many buildings that in the first case would seem silly to replace as existing but if done properly have actually turned out very well. I have also seen so called " modernisation" that has totally ruined old buildings that would have looked fine if restored with care. A lot of restoration needs an " attitude of mind" & once those involved can be convinced that the end product is worthy of effort some really good buildings can be maintained quite easily.

I had a 16th century house & wanted planning permission to build another in the garden alongside. It took 3 years to finally get planning permission & meant that i had to put the house right on the pavement line. Something I had resisted . however, once my architect turned to me after the second rejection & said " can you let me design the house now" it was passed & won the European Architectural Heritage Year Award. I had to admit I actually liked the house more than what i originally wanted.

I used to spend hours discussing minute joinery details with architects & conservationists & if I listened I could often find ways of doing things to achieve the results they wanted quite easily.

I did work on houses, churches, castles, Woolwich Arsenal, Lighthouses, Bridges & the like. Having a contract with the London Docklands Development Corporation for 3 years was really interesting to see the host of fine buidings we have in London . I do not feel that any did not benefit from the care that was put into them.

To let some of the butchers run amok with these buildings would be a betrayal of our past & a loss of some great buildings.

So whilst some may seem not worth saving I think the principle of conservation is an important one to be cherished.

My biggest disappointment was not to be able to rebuild a local windmill complete with sails because the owner went into liquidation.

Some forumites here soon get the hump if people start chopping bits off steam engines at will

Thanks John

I was OK up to " 40 watt light bulb" then you lost me--- so it will be a call to Warco on Monday

Actually the real problem is that when i installed the lathe I placed 4 pieces of 225mm catnic lintol down first & leveled & bolted  them down including fixings at the back by the wall. I then lifted the lathe on its Warco bench onto these to give me a 225mm higher lathe. So it is not just a case of undoing a couple of bolts & easing it forward as I have to hire an engine hoist to get it off the catnics just to open a back panel. So it all gets a little messy.

I did the same with the mill & it really helps with my back as everything is so much higher for working.

Trouble is that getting any  panels off will be expensive to start with before I even get to look inside
