Yup, I find it's a fine line between getting enough heat in and over cooking it and glazing/oxidizing the surface.

Most brass work I do at 300-400° (and yes, this is probably exactly why I have problems occasionally) but I am finding the blow torch much better even if it it's not as controllable or accurate. What I really want is one of those uber small micro flames with a needle like jet, pretty much a pencil point type thing, only downside is the cost and finding one.

I think they are primarily a jewelry tool. We had one made by or sold by Clarke. We ran the hydrogen, oxygen mix through MEK gave a very clean smooth flame.

I'm poorly skilled with an electric iron but have used a propane torch comfortably for most model work over the years. I also have one of those jewellers "Little Torch" oxy/acetylene hand pieces and it is a delight to use. A recent downside to it is that in the colonies, suppliers of oxygen and acetylene gas changed their operation to one of exorbitant hire of bottles from the bottle exchange system previously available - so I'm mindful of the gas supply I have remaining.
Looking online just now, these torches appear to be cheaply available out of Hong Kong from several sources for roughly US$30. Probably a knock off product and I don't know if the hose connections will be UK friendly - but at the price. . . . . worth trying?

Cheers guys, had a wander around the web for a while this morning and pretty much settled on this little Gizmo.

Sievert Professional Torch Kit

It runs on Propane or Butane and is about as small as you can get before you get into the exotic HHO torches. The flame is close to a sharpened pencil as you can get with out shelling out a lot of cash. It'll do me just fine for the little details like lamp irons, handrail knobs and pipe brackets. I'll pick one up after the hols and see how it goes.

Back to the Princess Coronation tender, pretty much all done. Only needs the intermediate buffers fitting and rear ladder, the buffers I'll fit once I know clearances on a 6' curve with the engine, the rear ladder.....well the first didn't survive first contact with the enemy and I clear hear C't'ain Cock up and his crew cruising the streets outside :p

It's a fold up affair and then the spacers are cut out once the rungs are all inserted and fitted, I get the theory, I get the practice, what I didn't get was the end result :eek: I do have a spare in my tender kit so will snip that out and build that one at a later date, it's not critical that it's fitted right now....which basically means that after this cup of coffee I'll probably go and do just that and risk the wrath of CCU :cool:

I dragged the old sheet out for some half decent shots, it does need a good wash and iron.

I changed the coal pusher vents from the prescribed 1 mm wire for some thin wall tube and I did add a tube in the well deck drain down inside the tank, but it...as my youngest used to say...mysterpeared :eek: I'll make another and fit it in later.

Overall it's not too bad, still a little too dirty for my liking, but I think I know why and hopefully I can circumnavigate those bear traps next time....or the time after ;)

I'll be very interested to see how this goes, Mick. In short, I'm happy about trying butane driven torches, but these extreme gas torches are a bit beyond me. (Just think A level physics and chemistry). And everything I knew as facts in physics are now wrong.

If it works for you I may just follow......

For the moment my Antex soldering station at 300 degrees and 140 degree solder works well for me, even with brass. But I use the largest bit I can fit.

What do you use for oxygen? It appears to be £16 or so, for a small bottle, with a list of extras that make your eyes water. The Hho thing looks cheaper over a year or so?

Thx

I did look at those but decided against it for a few reasons.

It has two knobs to twiddle to get a decent flame....twice the workload.

It requires two gas bottles, one of which would probably be only available from a bespoke supplier and costly to boot.

Third and probably most important, it's made in China, you'd have to be bonkers to connect something like that to two bottles of highly explosive gasses in a domestic environment. There are two items you never buy from China, three actually, Batteries, things that make fire and electrical goods...the latter often doing the former all by it's self! :eek: None are conducive to your health or well being.

Fourth, if it looks too good to be true, it probably is ;)

I have a Proxxon blow torch and it's fine for larger work, I have an even bigger plumbers blow torch for domestic pipework attached to a butane bottle and never had to use it as yet, except for plumbing work, it's excellent for that :thumbs:

I did have a cheap ebay mini torch before, like others I've read about, it turned into a flaming hand grenade one day; luckily I was lighting the wood burner so quickly threw it in there, closed the door, put a large piece of wood in front of the glass door and waited until all the gas had burnt off from the leaks.

These look handy but I'm just wary that any that might be respectable and probably double the price from a 'UK supplier' are probably from China and having the price ramped up.

The HHO welder is more appealing, for starters there's no gas bottles lurking around, it's single valve operation so easier to use. But once again you're looking at a Chinese made model for economy, which is electrical and makes fire :eek:

And everything I knew as facts in physics are now wrong.
Under modern physics (well fifty year old physics as nothing new has been discovered for fifty years) your facts are also correct and also, due to an error in scale, have been swallowed by a small Scotty dog called Archie (owner Adams, D). The trick in modern physics is to never observe anything as observation causes everything to collapse, especially the seas. That could be why there have been no new discoveries for fifty years.

I fully agree with everything you say about Chinese hand grenades, but it is pretty easy to adjust the flame correctly. The propane is basically only on/off. The flame is adjusted by adding the right amount of oxygen to the mixture. Did that in an earlier life with larger scale tubing.

My original Antex soldering station gave good service for 27 yrs until its final demise, on contacting Antex the nice salesmen said as I was such a loyal customer he would offer me a new soldering station with a 35% discount :rolleyes:. How could I refuse ? Anyhow after 18 months this new iron also died ! After some detective work it was found the good old British Antex irons are now manufactured in China, enough said. Hence I am now a happy ERSA owner, and very good it is too.

Yes and I've done it before when brazing in my earlier years as a refrigeration engineer :thumbs:. I'll be turning this device on and off 20-30 times a day (possibly more, it's one of those acts you do without thinking on a self starting mini torch) on a good session; turning on (and off) two knobs is going to be a chore, especially when I know there's a perfectly good item (though more expensive) available with one knob for control.

I'm also not overly keen on having a bottle of oxygen and propane/butane/acetylene inside the house, less so if they're attached to a Chinese flame thrower. I'm more comfortable with 1-3 Kg bottle of butane or propane attached to a Swedish professional built blow torch from a known supplier like Cookson gold. It's a comfort and risk thing.

If I had a big garden shed 100 yds from the domestic dwelling, hey ho, off we go.

I'm all for saving money, but not when it comes to tools for my hobby, those savings can be made elsewhere :D

Hi Mick,
Moving away from flame throwers, the tender looks superb. I don't see the slacking pipes but the supports for the raves appear to have a groove to fit them, so I assume they are on the "to do" list.
Cheers,
Peter

Hi Mick,
Looking at refference photos, the three fastenings for the slacking pipes on the outside of the raves, appear to have been on all the tenders including the non streamlined ones. I completely missed them on DoS and I ain't risking messing up Warren's paint job, but you could easily fit something to represent them.
Cheers,
Peter

Cheers.

The slacking pipes are not fitted as yet as I'm waiting for some micro bore tube to join the pipe to the nubs of the bulkhead fittings.

The three fastenings, originally two, pre-originally none, are bolt heads, to replicate those you need to press through from the inside (too late for that and realistically was never a satisfactory option) or add a fake nut on the outside. If you do that then you need something on the inside to hold the pipe and I've yet to find a clear, well lit decent photo of whatever clip it was. I'm also not convinced they're on every tender either.

So at the moment the additional clips are not near the top of my priority list, more so with this being an out of the box build commission build, priced and agreed accordingly; but I will converse with the client, as there is always some wriggle room for little bits here and there.
