I was recently gifted a Svea 123 by a very generous stove-friend in the USA. This lovely stove came in its really neat Sigg aluminium case, but I wanted a case/ windshield so that I can use the stove outdoors. I have had a small project underway to make such a case for it. This is still a work in progress but following @Tony Press comments about a similar requirement I decided to take some photos today, and make a post here. I obtained a 100mm diameter stainless steel kitchen storage pot approx 130mm high. I made the cut-out with a thin abrasive disc fitted to an angle-grinder and then drilled the ventilation holes using an electric drill and a set of indexed drill bits. Here are the photos: The Sigg-cased Svea 123 as I received it: Here is the stainless steel case/windshield that I have made for it: Once out of its Sigg case we have the Svea 123 in the home-made Stainless steel case/windshield: I have chosen the Kerophile trivet for use with Ibriks and my small kettle: After use the the whole outfit can be packed like a "Russian Doll" into the home-made windshield/case making a secure small volume for storage or transit: Finally here are a few shots of the stove operating in the home-made case: Please note that the three photos above were taken before all the ventilation holes were drilled in the case/windshield. Best Regards, Kerophile.
Excellent work kerophile. Your windshield looks like it was made for the 123. Of course it was made for the 123, so maybe I should have said 'made originally by the manufacturer'.
Hi Kerophile, please, do not take this as criticism, but I dare suggest to add a heat shield between the burner and the tank, there is a lot of backward reflected heat from the bottom of pans, and 123 are hot tanked by themselves to be helped in that sense. (presumptuous suggestion driven by envy for that really professional looking add on, mine tend systematically to look like crap)
Nice kit! I always like a set that fits together neat and makes a self-contained setup all complete. really great work. Ivan
Thanks, @kerophile. That's the kind of thing I was thinking of - you've done a great job with that stainless steel container! Cheers Tony
Very nice stove, and great job on the wind screen. One correction: this doesn't look like a 123R, more like a 123, and looks like an older one. Congratulations! ....Arch
Hi, @ArchMc , and @Tony Press , you are of course both correct. The stove is an early Svea 123, with the downward sloping control assembly. I will ask a Moderator to correct the title and text. Thank you. Best Regards, George.
Hi @orsoorso , you are correct about the need for a heat-shield to prevent potential over-heating of the fuel tank. I did say the project is a work in progress, and I have been considering my options. I took some photos of possible alternative pot support arrangements and will post them later. I will also share some thoughts of the design considerations which stove makers must have faced in making cases/winshields for stoves, since this exercise has certainly brought them to my mind. Best Regards, Kerophile.
Hi, as promised here are some thoughts on the case/windshield I am making: 1. At the moment I have retained much of the strength and structural integrity of the case by having only one large cut-out and a modest number of additional ventilation holes. 2. This means that the lid fits, and the case is a viable storage/transport container. I have to load the stove into the case via the top and having a fixed heat shield would be impossible. I could construct a movable heat-shield that could be positioned after the tank is loaded, or insert a partial one via the front cut-out, but this relies on any operator being aware of the need for a heat-shield whenever the stove is used. It is also one more loose piece to be lost! 3. My trivet/pan-holder grips firmly onto the top of the case, helping to make the case more rigid and offering good support for whatever pan, kettle or Ibrik I chose to use. 4. An alternative approach to the case/windshield is to adopt a front-loading design similar to that used in the 1930s Primus No.71L: https://classiccampstoves.com/threads/primus-71-e-−-mid-1930s.27916/ Here the front cut-out extends to the top of the case, an intergral heat-shield is fitted, and the stove can now be front-loaded into its case. 5. The rigidity of the case, which could be compromised by the big cut-out, is retained by the integral heat-shield. Cooking pans are supported on three brackets riveted to the top rim of the case and placed equi-distant around the circumference. This approach allows a good gap between the top of the case and the base of any cooking pan being used, which should help avoid overheating of the outfit. The lid of the case/winshield is deep enough to still locate on top of the case for transport/storage. 6 I had done some preliminary work on following the side-loading/ integral heat-shield approach and had taken photos, although I did not include them in yesterday's CCS post. Here are some images, showing pan-support brackets temporarily stuck to top of the case/windshield. In practice these would be mounted on the inside surface ot the rim, so as to still allow the lid to be used: 7. If I now install a heat-shield just below the level of the burner, I can cut a slot in the front of the case and into the heat-shield, which will allow the stove to be front-loaded into the case/windshield. Alas, the presence of the fixed windshield means the case can no longer accept the SIGG-cased stove for transit/storage, so goodbye Russian Doll. As I worked on this home-made stove case I have come up against the same design choices of stove designers long-dead. Compromise is the name of the game as some choices preclude other options. I actually have three identical stainless steel kitchen containers, as my supplier (a Charity shop in Edinburgh) would only sell the set. This allows me to experiment and perhaps have more than one final design. These are my thoughts, which I share with you, and I await any comments. Best Regards, Kerophile.
@Giri The ikea utensil pots may well be a good starting point they are stainless steel as well, I had a go with one but found it a bit tough to cut so made a bit of a mess of it and gave up! Cheers Nick
@kerophile You could also go low-tech on the heat shield -- just a sheet metal disk with cutouts to allow it to be arranged around the valve riser and over the tank, and with some tabs bent down to maintain an air space over the tank. This is what was done with the Phoebus 725. Almost seems a shame, though, as the rest of your design is so elegant. ....Arch
Hi Arch @ArchMc and fellow CCS members, I did consider making a three-legged stool-type heat shield but thought it would take up too much space when packing the outfit. Here are some photos of the current prototype. This is the Russian Doll Svea 123 case/windshield with removable heat shield: The first image shows the outfit packed in its case/windshield, the trivet, heat shield plate, and case top are then removed and in the 2nd and 3rd image, one can see the SIGG-cased Svea 123 in the case/windshield. Images 4 and 5 above, show the SIGG container opened, to reveal the Svea 123 stove. Image 6 above, shows the interior of the case/windshield, and in image 7 the stove has been inserted into it from the top. The 3 support nuts for the heat shield can be seen at three points on the innner circumference, and close-ups of two of these nuts/supports are provided in Images 6 and 7. These nuts/supports have been carefully sized so that the Svea 123 stove in its SIGG container, can still fit in the case/windshield for transit and storage Image 8 above shows the flat doughnut heat shield and trivet alongside the cased stove. The heat shield is inserted from the top and is supported on the three nuts (Image 9), The trivet is then clipped onto the top of the case/windshield (Images 10 and 11). Finally we have a couple of additional shots to illustrate the relative position of the heat shield (Images 12 and 13) The nuts are fitted on stainless steel button fasteners, which provide a secure and neat finish (Image 14) As I said earlier, I still have another two containers which could be made into cases/windshields, perhaps with the heat shield permanently fixed in the case, and the front cut-out extended to allow front-loading of the stove. However, the removable heat shield does allow the whole outfit to be securely gathered into a single package for transit and storage and I believe that the Russian Doll approach has a lot going for it. The heat shield can be stored either on top, or inside the case/windshield for transport and storage. Best Regards, Kerophile
