Agree with Jason - small working engine, used to power all sorts from dynamos to sewing machines. You wont find drawings specifically for that item but making your own is very simple. Im on the lookouf for a project like that so if you decide to move it on please let me know.

Thread: Silver soldering a Minnie traction engine boiler
31/08/2020 20:11:06

Now thats a massive improvment, well done indeed. I almost deleted my words as I thought they would be taken the wrong way but im glad they werent.....the way the solder has run on the inside is a sure indicator that it was at the correct temperature and all should be good.

Mark, well done but some words of caution from someone who does this for a living.The solder hasnt flowed correctly on some of the tube joints, possibley burned out flux or more likely just not enough heat, also the top rivet looks like it hasnt been soldered (might just be the light). Before proceeding with the build I strongly advise you to re-flux the tubes and re-heat until it all flows smoothly. If you have even the slightest problem in this area it is near impossible to correct once fully assembled and soldered and then the whole boiler is scrap. Any lumpy bits of solder indicate potential problems. Picture two shows two perfect joints and two not perfect joints, they all need to look like the smooth ones or they are likely to leak.

To answer Bob, you cannot easily compare the process of arc welding to soldering. One relies on a filler metal finding its way into a gap by capiliary action (dont get me started on gaps!) and the other deposits liquid metal onto the surface, gap or no gap. In reality a boiler constructed entirely without any flanging and competently silver soldered would be just as strong as a similatly welded boiler. Flanging originated in the days when boilers were riveted together and then cailked with soft solder plus its difficult to hold a boiler together without any flanging but it has been tried and done by the Australian federation whilst they were investigating this very notion. All their joints passed.

Most decent hotels in Germany give out comp Haribo......why?

so several people called to quote....I just want it replacing with a similar one.....why cant anyone understand this simple concept......I dont want to change to a combi, I dont want to replace my 12kw item with a whopping 40kw item....i'm seriously thinking of retraining because if everyone elses experience is like mine there must be one heck of a market for it!

One man band but with 20 years experience.......obviously not with boilers!

Thread: Copper boiler plate flanging, or not?
18/08/2020 11:42:37

Interestingly the Australian Fed who produce a far more detailed set of regulations than the UK conducted testing with full flange, hardly any flange and no flange at all (simple yube with end plates). All three were perfect under test conditions with no distortion between them. They published their findings...ive got it somewhere! My boilers employ a minimum of 3 x thickness to flange ratio and are turned to fit. Ive never had a boiler returned for a defective joint and ive made hundreds.

Thread: Who trains these ideots?

Came home to no hot water. Calls qualidied, experienced plumber who diagnoses issue before hes even been to see the boiler. Orders new part, arrives and fits it...nothing. Then does a bit of investigating and finds no spark - need to order new coil pack and it will be expensive! These coil packs are almost identical to those fitted to modern cars which operate under severe conditions and rarely fail, whilst ours has produced maybe 100 sparks in its lifetime. Logic tells me its not likely to be the coil especially as a failed spark wouldnt have caused a shutdown in the first place -I put meter on input and zero volts, so its never likely to work. Have a quick look at pcb and its propper toast so a new pcb is needed (burned beyond repair), Now given that ive never so much as looked at a domestic boiler in detail before and that it took me less than 5 minutes to diagnose the problem how are people like my so called plumber allowed out of the house? He will of course want paying for the call out and replacing a perfectly working part and if I hadnt taken a look myself would today be fitting an even more expensive part to replace the fully functioning one....would he even have got to the pcb? Am I obliged to pay for something which in no way fixed the problem? I despair, I really do. Told him all this, he advises a new boiler at £1800....alternative is new pcb at over £200 which comes with a 1 year warranty..... A quick google and I can get a recon unit with 12 month warranty for £34....

"I don't understand JD's assertion that modifying a published and proven design is not allowed".....thats because you are most likely not aware of the UK Boiler Regulations. You can do what you like in your own garden but if you want to join a club/get insurance/take it out in public then the rules have to be followed.

The problem your having with the sf24 is that the copper is not getting hot enough. I often have parts of a boiler going dull red when using sf55 and this can melt as much as 200 degrees lower than 24, so if I were to need to up the temperature by another 200 degrees I doubt there would be any flux left (it takes quite a while to get a boiler to that temperature and the flux doesnt last forever). I only ever use one temp of solder regardless of the size and type of boiler and have yet to have a single joint fail due to this. Brian is correct re getting the solder to stay in place - exactly what I do. Just beware that there is a lot of very bad advice as well as good out there.

well im none the wiser...just read that it might relate to NPT.....who knows?

Sure enough I put the wrong link in.....but the words are exactly taken from the link I should have put up......apologies all round.

Im looking at a water pump on ebay **LINK**

the item describes the thread coupling as 2E - hose 20: 2M screw 20 (3/4). Whilst I can make assumptions as to what the thread is can someone in the know please tell exactly what this means in easy speak? Thanks.

Thread: Mono or Multi tube water heater
20/06/2020 22:43:10 burnley solar is a complete non starter, indeed rain power would produce more output. I have thought about converting an old gas boiler, no health risks as outdoors, stock leccy heater is 2kw and raises temp roughly 2 deg C per hour....and seems to cost a bomb.

Our hot tub easts through electric at a scary rate - nothing wrong with tub or heater its just how it is. I got to thinking that I could easily make a stand alone heating unit for it running off propane (We use a lot of propane as it is). Then I tried to determine if it should be a mono (as in flash steam) type heater or a multi cross tube type heater...and I cant get any decent answers. Obviously it will be designed and built along boiler type materials so it can be well insulated, it only has to heat the water to a max 45deg C, 800 litres over about 8 hours. Whilst I have an abundence of copper tube and small bore pipe I would like to keep it as simple as possible. I will make the burners as standard PSB boiler burners as they put out good heat and dont use much gas (they will have to be tweaked to run on Propane though). Any suggestiond?

Thread: Hermes Parcels
09/06/2020 21:07:38

We at Pendle Steam Boilers use Hermes for almost all of our shipping, the majority of which goes over seas. So far they have managed to lose a £600 boiler but otherwise have delivered everything safely. You cant beat them on price and they paid my claim with no hassle. The good part is they have customer service who you can get in touch with unlike most of the other budget carriers. One gripe is that they will periodically claim your parcel was over weight and charge you extra...once bitteb and all that.....we now take a photo of the item on the scales! Last week they tried it again but soon retracted the invouce when shown the photo.

Thread: Silver Soldering LG2

You will have no problems using Colphos (90), it contains almost the same lead as LG2 but was created with machinability as its focus. It silver solders without any issues.
