|Thread: Copper tube for boiler|
Emailed them this afternoon ( sunday) & received a reply immediately from their MD. Pipe is 1.5mm th & they can obtain 2.5 th if I wish. i have ordered 1.5 as that is what is required on the drawing. i now need to get the copper for the end plates which is considerably thicker
I always thought that inspectors operated from clubs & club membership was normally a condition of them doing the work. Clearly I was wrong.
I have an email that suggested that you put an email querying the source of tube
May I suggest this link. I have not contacted them, but there are others.
Edit previous comment re design
I know the size is 108mm but on checking the manual it says that originally the design allowed for 4.5 inch diameter but the drawing size was reduced to 4 inch due to non availability of 4.5 inch. That tells me that 108 mm diam is perfectly Ok.

I am following the instruction set that I purchased from the designer, so there should be no problem. Making the copper thicker than the detailed 1.5mm should not be detrimental to the construction.I am sure that I can do a pressure test myself, following all the info one can get online .
As for using a club just to get a test cert is, in my view, wrong. If one joins a club one should do it to become an active member; not someone who turns up just to get a test cert & then disappears. That is something that I cannot do as I am already member of an RC flying club & I am a very active member of my local sailing club.
I believe that the nearest club, 20 miles away in Chelmsford, is more interested in locomotives anyway
Thanks for the replies. The drawings call for 1.5 Th wall but I just felt that as I was buying spare I would go for 2.5 th. Suppliers like Noggin end at £10-00 per inch are just too expensive. So far I have found 300 mm lengths at £38-00 each
As an example, I can buy a 1.5 metre length of 1.5 th walled copper for £78-00.+VAT delivered
However, I will go for table "Y" with 2.5 Th wall ( obviously much dearer) which will do me for now. I was just concerned about the effect of a concentrated heat from a burner on the copper, albeit with water inside.
But I will research C106 as suggested by Nigel
I need a 12 inch & 3 inch length of 4 inch diam copper tube for a boiler on a PYRTE traction engine. The cost from most model suppliers seems excessive, especially as I have never tried silver soldering such an item & it may end up in the bin
I can obtain a 1.5 metre length of table "Y" copper which is 108 diam with 2.5 Th wall for a much more reasonable price ( per metre that is) & gives me a chance to make a mistake as there is some spare to boot.
So what i want to know please - Is it the same grade of copper that is being sold by the model suppliers & will I be making a mistake buying it? I do not intend to get any test certs. It is for my own pleasure only. Working pressure is 45 PSI. Will the burners have a negative effect on the copper etc etc

|Thread: £1000 to make a Spitfire aircraft fuel tank gauge. Can it be done cheaper?|
If you had not got enough fuel would it have made any difference ? Knowing that you have just run out of fuel ain't going to make life any better. You would have still not made it to the airfield & you admit there is no alternative airfield.

Yes! couriers do a fantastic job these days. Deserve more praise than they get.
|Thread: Covid causing mental health issues.|
Imagine laying in bed on a thursday evening wondering how you are going to pay the staff on friday morning when you have just been told by the bank that they are going to call in the overdraft & reposess your house which you have used as guarantee against the loan.
Must be even worse if you throw in some covid for luck. Regardless of what you are told about loan holidays , the interest is rising & the loans still have to be paid- eventually. So it is not all about those with low IQ.
Then add in a bit of marital unrest & you have a pending suicide on the cards, I bet
Imagine being a wife locked in a 3 room flat, day after day, with some barsteward who wants to bash the life out of her, just because she says the wrong thing, or because the kids play up a bit.
I would have thought mental health issues will be VERY high on some people's agenda.
|Thread: Warco wm240v|
Mine stalls several times a session. Gutless thing. Less power than my old Drummond M type. takes several presses of the stop/start button to get it going even if it has not had a stall. If I forget to press the stop button after a stall or after i have pressed the start button & it has not started, it sometimes starts whilst i am doing a set up, which has caught me unawares a couple of times with my hand on the chuck.

|Thread: "The Unique"|
Many years ago & I am talking about many, we went to some relations in Norham on the Scottish borders. Their house backed onto the Tweed & is still there to this day.I had to go to the toilet, which was a dry one, with grass in it. The story goes (I was a very young essex lad) that I was heard to say to my mum " There is no lock on the door". On hearing this, my mother's aunt is said to have replied, " Why should he worry? We have lived here 50 years & never had a bucket of s..t nicked yet"
Sorry mods--- but I have never forgotten the story & have no idea if it is true or not, but the dry toilet comment prompted me to repeat it-- put me on 7 days punishment !!!

|Thread: Mystery Object ... This one has me beat|
55 years since I did surveying at college, but did not these marks all relate back to a point in Newlyn in Cornwall?
Or is that no longer the case?
|Thread: Strength of Beams|
The example you refer to with circular holes is not what I was referring to. If one wants to put a cut along the web of a beam then separate the 2 halves & offset & then re weld to form a deeper castellated beam one needs an edge to weld to. If the line was a wavey one the meeting points would not meet in a way which could be suitably welded & the holes would NOT be circular. Standard castellated beams cut from a simple I beam would be cut such that the line has flat edges for the weld. The hexagonal hole thus remaining would still leave room for services & I do not recall having difficulty installing them. I did fit quite a few tonnes of the stuff in a number of new schools halls etc But I do confess, that was 40 years ago & things move on, so If I am wrong then I stand corrected
The example in the one in the link would , presumably, be cut from an I beam with considerable waste.
Just one point-- They are not normally circular holes but hexagonal. That gives flat surfaces for the weld at the new meeting point.
Going back to the OP's post & comment about the ruler. It is certainly stronger on edge.
Just an itemt that may solve a problem for someone. If they want a beam for a construction in a house etc, then a piece of flat plate the depth of the joists (or slightly less), bolted betweem 2 timber joists makes an excellent beam. It is cheap, & can be inserted into construction easily. Plasterboard etc can be easily nailed to it without awkward noggins etc. Herringbone noggins can be added in the space as normal if required to avoid rotation

|Thread: Power chimney sweeping|
My last house had a wood burner & the wife & I (well she did!!) decided the chimney needed cleaning. As a builder I regularly had to clean chimneys of refurbished houses so had a brush. To rod drains I had a 100M length of black underground plastic water pipe to which I had fitted a screw fitting for a plunger. This also fitted the brush.
So after suitable covering furniture, the wife & I started sweeping. My house had a flue with a number of turns & was 3 storeys high so needed a lot of shoving. It also needed a lot of pushing to get the brush up the flue. As we all know ,difficult jobs call for lots of swearing between couples.
After a while sweat was pouring off us & there was a knock at the front door.
" Oh! who the b..y hell is that" " Tell them to F off we are busy " etc etc
"ignore it". "You go," " No you go"
Eventually my wife swore, (at me & chimneys in general!!) removed overalls & went to front door
To be met by a chimney sweep brush on the end of a plastic hose.banging on the door. We had not realised that we had shoved so much that the thing had gone up the chimney & back down the outside again !! Being off a roll it curved back in towards the door & was swinging in the wind with the wooden centre hitting the wooden door

|Thread: Who trains these ideots?|
Back in the 90's I had a contract to fit screens in 17 schools in Thurrock in the main reception areas . These were to restrict parents from entering the schools & attacking the staff. Alarms were also installed to call more staff in difficult situations. The events were, apparently, very common & some staff lived in fear of attack from aggressive parents as well as children. I was building a school alongside another school in East Tilbury & witnessed a child of about 10/11 actually attack a teacher & it was a surprisingly violent incident & he was punching the teacher in the face.
I cannot find Brickkies original post & i should hasten to add that I was not trying to belittle the art of bricklaying. What I do find wrong is the attitude that we need to spend years doing appreticeships when they are not always necessary.
Funny you should mention arches. My first house, that I built myself,had an arch way 2.7 metres wide & 5 metres long, all in brickwork. It was a design necessitated by the fact that the house was on the high street & vehicles had to pass through
I won the European Architectural Heritage Year Award for that House, when I was in my early 20's
My next award was for a community centre built on to the end of a very old village church many years later.
I never served an apprenticeship, but employed quite a few. I never had them sweeping floors & wasting time making tea if I could help it. I employed others for that task. My attitude was that they were there to learn the trade, not how to make tea. They did have to understand the need for tidiness in the workplace though.
