What brand of torch? Some of them are harder to get parts that need replacement parts like O rings & tips.

One of the torches is labelled "Sievert/Sweden", but I don't know if that's the same brand as the rest of the gear. What does the outside of the lid say?

The torch is from a company called Oxygenium, based in Schiedam. The part labeled from Sweden is part of some other set. Haven't looked around much yet, but iirc correctly the one my brother uses on his work is from the same company.

Yeah, I thought the Sievert looked more like a plumber's torch one would connect directly to a tank of fuel without additional oxygen. If Oxygenium is still in business (or was until recently), it shouldn't be too difficult to get parts and service.

The little wheeled gizmo in the upper left corner could come in handy; it's designed to hold the torch tip at a fixed distance from the metal and roll across the surface, making cutting easier and more accurate. 

Yeah, I think that will really come in handy, looking around it seems that the company has fused, so the original name is not there anymore,. It the new company still produces torches. There is also some other part in there that I don't know the use for, maybe it doesn't belong in there at all.

At the end of the small rod there is a point, and there is a place for a second rod in there.

My money is on the long rod on the far left side screwing into the torch support and then sliding through the fixture you marked in the last photo, for cutting circles. Set the distance from the point to the torch at (or slightly larger than) the radius of the desired circle, and you're good to go.

I just made something similar myself, detailed HERE.

Ah that makes a lot of sense actually, thanks for clearing that up!

Here's a photo of something similar, with a single wheel:

The Sievert propane Torch is top quality. I have a couple of them...bought them back in Mid 1970s when I started out and was earning a living as a jeweller and silversmith.  Still in regular use now, last used two days ago to stress relief anneal some cartridge cases.

The nozzles are still available. The handpiece is universal and with various necks and nozzles will do fine silver soldering to hot felt roofing. Good website.

The large diameter neck in the middle produces a helical flame which licks around the back of copper pipe work for plumbing.

 

I built my first gas furnace from an L shape of fire bricks and an arc made from a third of an oil drum with ceramic fibre bats stacked in...powered by the big sievert nozzle it was enough to give me 650mm (26") heat on lengths of 50mm (2") square aluminium for forging these window grilles.

 

Sievert are one and the same with Primus who made paraffin (kerosene) cookers and lamps...the sort under pressure rather than wick burners.

Interesting detail. Who knew?

Sorry if it was stating the obvious. I didn't know whether they were exported to the USA.

In the UK the pressure lamps were either Tilley or Primus brand. But the paraffin pressure stoves were almost exclusively Primus. Blimey just done a search for an image and see they are worth £50-85 on eBay...we have two or three in the shed I must look out!

Alan Knight, the smith I worked with when I left college had a neat folding petrol pressure stove which collapsed into a rectangular box made by Coleman I think, and I had the impression that was ex military USA. We used it every day for tea and coffee brewing

The only company that I know of exporting something similar to the U.S. is Aladdin. I have quite a collection of their lamps and heaters still looking for one of the stoves. The Aladdin Blue Flame heater also serves as a stove.

Back in the day Primus made small, white (unleaded) gasoline stoves for backpacking and camping.  Not sure if they were the wick type or pump/pressure.  They were smaller and more compact and lighter than the single burner Coleman brand stoves.  I still use my Swedish Svea stove (wick) for camping but it is a bit scarier and a hassle to use compared to the small propane and butane stoves.  I do like the gadget factor.  It also impresses younger folk who have never seen anything like it.  It is sort of like showing off and using a slide rule rather than a calculator or a phone.

George N. M.,

The little primus stoves were the wick type. I never pumped up my stove.

Where can I get one of these? Or something which would serve the same purpose? It appears to have broken off mine at some point. 

It's a broken-off oil cup. You can get one from Mcmaster-Carr (Commercial link removed per TOS) and others. You would not necessarily fill to this level, or you will probably have a lot of leakage. A smaller amount in the bottom of the casting (that the motion of the gears can distribute) will probably serve you better.

Actually it is an oil level pet cock. The oil cup is the one at the top where you put in the oil. Any good plumbing store should have them, I got one at ours for my old tractor.

(And is the type of thing you look out for at the scrapyard on old machinery; no reason to contaminate a steel melt with it and my scrap yard owner makes me a reasonable deal on the "brass".)

A gift from my generous neighbor, he has a LOT of it laying around his garden for decoration. Would I be correct in assuming it's wrought iron? 

 

The only way to tell is to test. Cut halfway through and bend it until it breaks. If it's wrought iron, a fibrous structure -- like a broken green stick -- will be revealed. 

Keep in mind that each link may be a different metal, depending on what was available when the chain was made. Strictly speaking, you would have to test every one.

If it is WI, though, make your neighbor something nice as a thank-you!

You can also spark test it with a grinder.

Thanks for the swift replies. I just cut a link in half and the sparks were kinda dead and reddish so that link is WI and hopefully the rest are.

I'll be sure to make my neighbour something nice in return.

Bottle openers are always a nice thank-you. If you make one from some of the WI, make sure to etch it in vinegar to bring out the grain pattern.

That's a great idea and thanks for the etch tip, I'll probably make some sort of key ring as well. I actually haven't made many things so far so this will be a fun learning project. I know this material has to be worked really hot.

 

It does indeed. It can also split when punched and drifted, so be careful.

Wrought iron has to be forged at a much higher heat, think welding heat. At lower temperatures it will split like JHCC said.
