Radius “Special Silent” UFO Silent Burner Cap Compatibility

Hi BD
Can I use the Radius UFO silent cap on a standard silent burner?
Signed, Silent Guy

Nope. Sorry, Silent Guy. A lot of people don’t realize that there is a size difference between the two types of burners. The Radius “Special Silent” burner is substantially smaller than the standard #5-sized silent burner.

“Special Silent” on the left, standard #5 sized burner on the right

If the spigot tube on the “Special Silent” (aka the UFO burner) looks smaller than the #5 spigot tube, that’s because it is. The “Special Silent” spigot tube has an outer diameter of 14.5mm while the OD on the #5 burner is 16mm. So, no way the UFO cap will fit on the #5 burner.

If you have not got a #5 burner in hand, here’s how the “Special Silent” compares to a standard sized #1 roarer burner. Hope that helps. BD

 

BernieDawg Cap Shapeways and i.materialise Sales Issues!!

So! Lots of people are wondering what is going on at my Shapeways and i.materialise BernieDawg silent damper cap stores.

I wish I had good news. And, I wish I knew all the details of the real things that are going on “behind the scenes”. This all hit me as a big surprise and I’m still discovering and researching the truth behind the problems, but here’s what I know for sure right now.

Shapeways Increases
Shapeways raised its prices to print my products at the end of June 2022. The increase on the models ranged from 86% to 113% increase per model, depending on which model. But, generally speaking and on average, an increase of 100%.

What this means in practical pricing terms is that a Minicap without Legs that was selling for about $30 USD in May was jacked up to $62 USD at the end of June. The PolarDawg, my most popular cap, increased from about $35 USD to a whopping $65 USD. The DragonTamer went from $45 to $90 USD. And, biggest jump of all, the massive Top Dawg cap for the British military #12 stove increased from $91 USD to $192 USD.

And, all this is before shipping and VAT taxes and the fees and add-ons that Shapeways likes to do. For the record, my markup, the amount I actually was seeing from the sale of each cap coming to me, was less than $2 USD per cap.

I questioned the folks at Shapeways about all this. Here is what they said:

I’m afraid this is not a repricing we have taken lightly and I can honestly tell you we would have loved to prevent this from happening.
Unfortunately however this repricing doesn’t come directly from Shapeways but from the vendor Exone who prints the Bronze Infused Binder Jetting Steel material, so we had no choice but to reflect these changes to the end customer.

Since Exone changed their pricing structure, It’s very likely that i.Materialise will soon have to change their prices as well, as Exone is the only company printing this material and thus very likely they are using them as well.
 
Again I’m sorry for the inconvenience.”

A 100% increase on printing my products raises the cost beyond what I think people will pay. The price increases effectively kill my silent damper cap business with Shapeways. So… I erased all my designs at Shapeways, erased all my customer photos and text descriptions and left you with the simple message that now appears at the entry page to the BernieDawg Shapeways store. https://www.shapeways.com/shops/berniedawgshop I’d hoped to alert folks that changes were in the works beyond my control so that caps could be ordered from i.materialise before they, too, changed their pricing (as suggested by the rep at Shapeways).

i.materialise Product Freeze
This morning (July 4th, 2022) I received notice in five emails from i.materialise that the last five orders placed at the BernieDawg i.materialise store had been cancelled. (Sorry to those who placed those orders. I had no foreknowledge from i.materialise this would happen and no-one at i.materialise gave me any warning.) All my models at i.materialise have been put “on hold” until they figure out what they are going to do. Here’s their reply to my email asking what was going on:

Thanks for checking back with us.
I must admit that I planned to contact you regarding steel printing around this time, but my colleagues were faster and already cancelled steel production orders. Apologies for this unexpected news.
So, for your information we unfortunately had to suspend the steel printing offer until a further notice (around end of July). This happened due to a technical issue over the weekend and the orders that were placed during this time and a bit before got affected. Thus, on Monday when everybody got back to work we removed the steel offer from the website and all the shop-items we had in steel changed their status to “Display only”. This is indeed a short notice or even a delayed one, considering the fact that issues happened on the weekend and we couldn’t react immediately.
We are working hard together with the production team to make sure steel printing is back asap, but still can’t advise the exact date when it is back online. On a side note I must also inform you that there will be price changes as well very likely, but more information should be available in the coming weeks.
Kind regards,

What does this all mean for BernieDawg silent damper caps going forward?

Well… as of the moment (July 4, 2022) I guess I’ve been forced out of business.

I have some of my designs I’ve ordered in alternative metal materials, but, just like you, I have to wait for those to be printed and shipped to me. Once they arrive (end of July 2022), I can do some testing to see if they will work out for use on stoves.

But, that said, they will likely cost 20-30% more than the bronze-infused stainless caps that I’ve been selling for the last 10 years. I will also have to work out some method of distribution/shipping/ordering, etc. Pretty tough stuff for an old guy like me to be doing.

I should imagine that IF you see my products for sale again, it will not be until the Fall of 2022.

I’m very sorry that this should be so. It is both sad and very, very depressing. When it comes to humans, it seems nothing good ever seems to last very long, no matter how hard some of us try to create something good and special in the world.

Now!! All of the above is factual truth as it has been presented to or experienced by me.

Here are some conjectures (informed guesswork, not fact) based on some of the statements you see above:

  • Both Shapeways and i.materialise NEVER printed their steel products. They lied to me and the rest of the world about this for years. Instead, both Shapeways and i.materialise acted as brokers and farmed the actual bronze-infused steel printing out to the single company that was actually printing bronze-infused stainless steel 3D printed metal  – ExOne.
  • ExOne has either decided to increase its prices (for unknown reasons) or has been hit by increases in prices from their metal powder suppliers in China(?).
  • China, meanwhile, has been rapidly developing metal printing technology.
  • It is possible that Chinese companies printing bronze-infused steel are hoping to drive ExOne out of the bronze-infused steel printing business by making the raw materials too dear for any serious person in the West to consider printing it.
  • It is likely that you will see my competitor who sells imitation caps that look suspiciously like mine continue to sell for some time yet as that vendor maintains a stock of caps. I would predict you will see that vendors prices increase in the absence of my competition. But, eventually that vendors stock of warehoused caps will be depleted, too. So, if you can accept the issues and problems with the competitions models, then best grab those whilst you can.

Thanks for all the support and products purchased over these years. You are the greatest! BD

Heinze Geniol German Army Kocher Stove Manuals

Down below I have some English translations of the Heinze Geniol German Army Stove manuals and box lid placard. Here are some photos of the stove I’m talking about.

I have a short video at my YouTube channel showing how to light one up with the quick lighter device: https://youtu.be/TEYuNicFRWE
The video has some links to both the storage bag and the windshield I show with the stove.

The stove comes with a multi-page pamphlet that describes operating, maintenance and repair procedures. It’s in German.

But, I’ve translated it into English. Just a couple of pages as a teaser for the PDF documents you can download below.

And, as it turns out, there are two different versions of the German language manual. I found this version one manual online here:
https://www.prela.ch/Anleitungen/bwkocher.pdf
Here’s the Version 1 in German which you can download here from my site or from the site at that link just above:
Heinze Geniol Army Kocher Manual Version 1 German
Here’s the Version 2 in German which came with one of my kochers and has some edits to create new sections and some corrections from version one:
Heinze Geniol Army Kocher Manual Version 2 German

So, I translated both versions. Here are the two smaller files that just show single pages:
Heinze Geniol Cooker Manual Ver.1 English Single page
Heinze Geniol Cooker Manual Vers.2 English Single page

For a booklet style view on your computer or device, download one or both of these slightly larger files:
Heinze Geniol Army Kocher English Manual Version 1 for viewing
Heinze Geniol Army Kocher English Manual Version 2 for viewing

For a document that you can print double-sided and get the pages located in the proper order (to make your own hard copy booklet), download one or both of these files:
Heinze Geniol Army Kocher English Manual Version 1 for booklet printing
Heinze Geniol Army Kocher English Manual Version 2 for booklet printing

There are instructions under the lid, too. They are not as good as in the manual.

Here’s the translation of those, too.

Hey! You are free to download these and even share them around. Please retain my little credit to me I put on the translated pages. It took me a lot of days to translate, so it just seems fair. Download and share them for free – it’s knowledge! Let’s be decent humans and share our knowledge and resources! (I don’t believe in trying to make money on documents that I didn’t even print or author originally. Nor do I believe in creating a silly “monopoly” on knowledge by restricting knowledge to subscribers. 🙄 Those ideas are weirdly mean-spirited and not very nice.👎)
You’re welcome, stove fans! 🥳 BD

Svea 123 or 123R Spindle Key Uses

The Swedish-made Svea 123R is a great stove. The “R” means it has a built-in cleaning needle. The spindle key that comes with the vintage stoves has several cut-outs in the key. The purpose of the cut-outs is to lighten the spindle key, to allow the key to dissipate heat and to serve as useful tools for the stove in the field. Here is a quick explanation of the functions of the tool cutouts in the spindle key.

Spindle key detail

Svea 123R – Loosen fuel cap

Svea 123R – Adjust spindle nut and tighten graphite packing

Svea 123R – loosen/tighten jet

The predecessor of the Svea 123R is the Svea 123 (it has no “R” in the stove name.) The spindle key that was bundled with Svea 123R stoves also had cutouts for this earlier version, the Svea 123. The keys were used interchangeably during the years that both types of stoves were co-produced.

The spindle nut is smaller on the Svea 123, and the opening in the photo below is used to tighten or loosen the spindle nut. Usually used to tighten the nut as the graphite packing in the spindle wears with use.

This part of the tool is for the spindle nut on the Svea 123 (no R)

This part of the tool is for the smaller jet on the Svea 123 (no R)

The cheaply made and low quality Optimus Svea 123R stoves now coming out of Taiwan still feature a spindle key that includes the opening for the Svea 123 spindle nut even though the Taiwanese never made that stove and that stove stopped being produced in Sweden pre-1970.

Some people, new to these sorts of stoves, or with little background on these stoves, will claim that the Taiwan stoves are of equal quality. But, sadly, those people have never had a genuine Swedish-made Svea in their hands. It is fairly well documented on social discussion forums about stoves that the Taiwanese Svea 123R stoves are of lesser fit and finish than the original Swedish made stoves. There have been quite a few reports about failures to positively shut-off straight out of the box. In my own work repairing stoves I have had a half dozen brand new Taiwanese Svea 123Rs sent to me in just the last year for failures to positively shut-off. The spindle seats are often poorly formed and the brand new stoves will leak right out of the box. If you are considering the purchase of a Svea 123R, PLEASE buy a used vintage one. There are lots of them around and they are much better made than the poor quality Taiwan stoves.

Primus Stove, Lantern and Appliance Dating Chart

Primus paraffin stoves, lanterns and blow lamps (blowtorches) are stamped with a letter code starting in 1911. The letter code can be found on the bottom of the tanks of these liquid fuel pressure appliances. The letters Q and AQ are not used in the coding system. Starting in 1955, the code method changed and a six-digit code was used. The last two digits of the six-digit code correspond to the year of production. The six-digit code can often be found on the leg of the stove or on the burner riser of the stove. Toward the end of the last years of Primus production, the code was no longer stamped on the stove but was found on the carton the stove shipped in.
There is often an additional number or letter stamped on the tank. It is unclear what this was for, but it is possible it was a production line identifier, or lot batch number.

Primus is the only liquid-fueled pressure appliance company of which I am aware that dated their offerings with a date code. Other manufacturers appliances must be dated by examining the features of the appliance and comparing them to catalog drawings, photos, illustrations and known dated appliances of the type.

You are welcome to freely copy and distribute this dating chart, link to the dating chart, or link to this webpage. Click on the chart or the photos below for larger and higher resolution images. While I made this chart from scratch, I am not the originator of the chart. For the record, I only published my homemade chart here after I saw that the original chart (found on a popular and well-known social discussion forum requiring a membership and/or subscription fee) has been published in full resolution far and wide all over Pinterest. So, the horse has already escaped the barn. I do not believe knowledge should be held ransom behind a subscription fee. Apparently a lot of Pinterest users agree, and you should agree, too. 👍

Here are some examples:
