Hi Martin

The majority of combis will have flow and return on the extreme left hand and extreme right hand 22mm pipes. But the pipe order is different on the odd combi, Vokeras for example are side by side extreme left.

easy way to be sure is run the heating and see which two pipes get hot.

The Iso taps are sometimes plastic handled affairs but some need a spanner or Allen key to turn

If there is no water coming out of the 3 bar PRV, then the expansion vessel is fine.

With the boiler switched off, check no water is coming out of the condensate pipe, (if it is then the heat exchanger is shot.)

Easy to check if leak is on system rather than boiler, just switch off isolation taps on flow and return under the boiler and wait 24hrs, if pressure on boiler stays up, leak is definitely on system.

Don't really recommend leak sealer it plays havoc with auto air vents etc and is a temporary bodge at best.

If one section of pipe is corroded chances are it will all be shot to some degree, concrete and copper don't do well together.

Pinched this video link from Madmodders so apologies to those who may have seen it before.

scroll down the page a bit to play the video.

When I worked in industry we had some Racal air fed welding masks, we only used them for really bad jobs such as air arc gouging or welding with flux cored mig wire. They were a brilliant piece of kit but heavy and worked off a rechargeable battery, this was 25 years ago so I'm sure the wearability will have improved.

I served my time as a boiler maker/welder but got out as soon as I could, all the old boys were, deaf, half blind, had bad chests, dodgy backs or missing digits........the writing was on the wall !

you don't say how big your parts are, could you possibly use a vibratory tumbler to knock the edges off ?

The Blue zirconium discs from ebay are as good as any I have tried from my local welding supplier, but you normally need to buy a hundred to get them for anywhere close to a pound each.

There are plenty sold at car boot sales and probably ebay that last about a minute each, you can see by looking at them that the quality is poor.

A pack of 10 Kingspoor or similar from my local welding supplier worked out around £2.20 each last time I enquired

£11 each is outrageous.

if you email me your address I'll send you a couple of the blue ebay ones to try, me and a pal buy them by the hundred and have 50 each.

Alan.

Try using a 0.8 tip and see if it feeds ok.

As someone has posted above, my inverter output is wired to a three phase socket (red 4 pin)

so I can plug any machine in, one at a time obviously. As long as the inverter is capable of powering the largest

machine you should be fine. I normally power the inverter down before swapping plugs.

if you want to run several machines at once from one supply, then a rotary converter is the answer.

Well i don't suppose you can blame them for having a punt at £3k when the only competition is up at £7k

Bit naughty not mentioning the impromptu DIY bed gaps !....as always caveat emptor

And who cares that the owner was a retired doctor, i might have been slightly impressed had he been a master

toolmaker or some such, but just cos he used to wear a stethoscope doesn't mean he knew how to treat a lathe.

When i built my extension i used a fair bit of steelwork including columns to support the main load bearing beam (rather than building brick piers) my architect used a friendly certified structural engineer who for about £80 did the necessary calcs. These came hand written on three sheets of plain A4 and were duly submitted to building control.

There was no covering letter or anything to suggest the bloke who produced them had any qualifications or idea of what he was doing, but they looked mightily impressive, i doubt anyone at building control would have had the knowledge to decipher if in fact they were beam calculations or moon landing trajectory calcs.

Being a good lad I did however follow them to the letter, and it cost me a small fortune in steel, the main span beam was only 16ft long and weighed a shade over a tonne as specced. Flipping ridiculous for what it was holding up. I reckon something half the size would have been adequate. Luckily i managed to borrow a tractor to lift it into place.

Calcs must have been ok though as its not fallen down yet......

Just spotted this on ebay.....I'm all for a challenge, but reckon if this poor mill was a horse it would be kinder to shoot it....what a shame ! One brave bidder so far.

Thanks for all the replies, much appreciated. I tried Steel Express, but two E24T billets worked out at £130 + delivery and Vat and was probably overkill for my needs. Tried metal Supermarket in Leeds and have been quoted £67 + vat for 80 mm x 500mm EN16T round bar. Thought that was fair enough so am collecting on Wednesday.

Just found this place **LINK** which seems to do EN24T in all manner of sizes, cut from plate, so might be the way forward, will give em a call on Monday.

Slight update, created an account at Parker Steel only to find they don't deliver to my area.......the search continues !

Yeah, it gives me a good margin for error ..........actually the steering arms are the bits bolted to the hubs that the track rod ends bolt to, i need to make a pair of these. John are you saying it would be better to heat treat EN16T or just S? i was hoping to avoid heat treatment. West Yorks quoted on S because that was all they had in stock. The prices quoted above are around what i had expected, i would happily buy half a length and keep the rest for stock at that sort of price.......why are some suppliers so greedy.
