@Afterburner Wow, I remembered a poem about this from one of the poets named Iran (Hafiz) who said: That made love easy first But there were problems
From the information I've got for my project, the coil tubing is slightly magnetic, so it could be made out of iron. I think you don't need to have such an amount of tools and investment to make these burners. Go back in time when Borde made these burners and what possibilies he may have had at this time. I also think Borde made this most likely by hand in a really small workshop (maybe only on room). Sure I have some good tools in my workshop, but all in all these are not this expensive. So what would be needed to make these small burners: - the parts could be hand saw, as nearly each part has a 90° cut (metall handsaw) - for doing the solding job, we need only a gas torch (for example: propane or if you want a mix gas of propane/oxigene or acetylen/oxigene) - when studiing the original pics, i've found these parts are silver soldert or hard soldert (so no welding mashine is needed) - for bending the coil you need only some form of pipe in the right size and a vice (maybe some additional heat will help for easier bending, so we already have the propane torch) - to make the "flower" we need some kind of a scroll saw - flower and spindle are pressed together using and anvil and hammer - some kind of small lathe for making the needle and valve components - a standing drill - a grinder When I was a teenager I brought my first lathe, a small Emco Unimat SL, with such a multi tool it would be possible to make the parts we need. This Unimat has a drill, a circular saw and the possibility to use it as a scroll saw or grinder and you can rotate the spindle with the chuck to made the angle of the needle valve. These lathes are not available as new ones today, but you can find them on the second hand marked. When I bought mine it was a complete set in a really good condition which comes in a nice wooden box (man this was nearly 20 years ago, how time flies). So to have a workshop with the needed tools to built those burners we need less than 1000eur/dollars/pound. and some guys can make this at their home in the kitchen on the kitchen table and doing the soldering job infront of their house or the backyard. For the cleaning and nickle finish you can give it to an external electroplater. Kind regards.
What I see in this forum is you still need some skill or knowledge for many if not all repairs or manufacture. Duane
I figured that he made fixtures and jigs to position parts properly. The spindle for one was probably an assembly. Aligning to the jet was made easy with the fixture. Then repeated over and over again.
I was thinking repair and manufacturing parts for all type and all size of stoves plus all accessories that they have/need. Emco lathes are very nice! Just month ago I bought Unimat 3 with milling/drilling column but there has only basic accessories with it. My table top lathe is Soviet made similar size to Compact 5. It's from time when Compact 5 was popular and Soviet & Eastern Europe hobby machinery appeared into the market to compete with Western made ones.
The machine tool requirements for most stove parts are very basic. It's the pressing and forming tools which are the tricky bit.
@Eppo I am waiting for the final result of your project to build stove borde with blue flames Maybe add my name to Borde lovers
Yes, pressing & forming tools were not in my list... e.g. proper spinning would need special lathe. I have seen few for sale with quite reasonable price but no room to accommodate it.Although normal lathe works for spinning small parts: Spinning with lathe Foundry would also be needed for some parts: Repro rare flame plates Then at some stage new building(s) are needed for all machinery.
Yes, I've done a fair bit of spinning and hope to do some again very soon, although I haven't the capacity for full-on 2-pint stove tanks! We live in an interesting time which is only getting more interesting.... look at how 3D printing has become affordable and accessible this last decade. It would now be child's play to model and 3D print say, a load of roarer burner head castings in wax for vacuum casting in bronze. In five year's time good 3D scanners will no doubt be affordable enough that an existing casting could just be scanned straight in to save the bother of modelling. Home laser engravers, and laser cutters, will likely be dirt cheap within a decade... There are some very good designs of home foundries out there, electric, propane, waste oil. Another advantage of the internet is that hobbyists are being begun to be taken seriously, and as a useful source of business. Acquiring materials and services in small amounts was once a lot more challenging than it is now, and many companies now see the value of small orders and one off jobs.
Sometimes it is really great what is possible throughout the internet. Not only meeting great people with the same interests and get a lot of informations, that I wouldn't be able to find somewhere else. That is what makes the internet to auch an great place, not these social media or the amount of cats videos on YT . Another great story: Maybe 15 years ago (or longer) I bought a broken MAG welding machine. It was an old one with a transformer, but a good Lorch modell and it was cheap and I was happy to got it for repair. The three primary coils were burned and I had to rewind the whole transformer. A job I wouldn't do anymore, cause inverters has become really affordable. But back in the days I was happy to have this machine and a use it on a regular basis till today. For rewinding the new coils I have to use new coil bodies, cause the old ones were burned too. Only the manufacturer label could be read, so I measured the size. The only one in the right size could be found at the manufacturers homepage. After an email request I got an answer that my order is too small, cause they only selling in huge numbers for production lines (up to 100 bodies or more). But the person who answered me gave me an advice that they are shipping free samples for science and development use. So I got my three coil bodies for free, even the shipping was free. I was so happy . Kind regards.
@Eppo Fantastic. Things often seem very rigid or black and white, but when real people are involved there is often a way to make things happen. Well done for repairing and rewinding. Inverters may be convenient but transformer machines were so smoooooth! Apologies for heading off topic as usual
So back to topic. Today I made the stove/wind cover. Even trash is usefull, so I made this cover out of an empty paint can (size 750ml). Made an open top with three standing points, the open window onthe side to insert the burner and add some holes for venting. Even it was raining outside during my test, the flame looks very smooth. It is very interesting how much different the flame looks with a proper wind cover. Maybe if I can take a better picture I can go for the stove of the month award . Kind regards
@Eppo Salam Congratulations, the blue flame has a score of 100 and it is a good sign for good performance. I still haven't achieved a completely blue flame.
@Eppo & @kohdarmiansali you both are making good progress! Maybe kohdarmiansali's burner is ready to make blue flame. Looks that now vapor flow touches to some obstacle on nut & coil interface. It seems that there is some metal particle/similar. Try to file off that particle and maybe then yellow colour will disappear.
@Eppo Hello, good morning, dear friend Did you use car gas or Coleman gas in the final test which was great? I once saw on YouTube that a person used a car cleaning spray to fuel a Borde stove
@kohdarmiansali : From the first start till now I only use car gas (Super95) which I easily drain out of my motorcycle tank. Cause I plan to use this burner on my tours with the motorcycle and therefore don't need an extra tank or gas for the stove refueling. I know this vid, but I think this cleaning spray is kind of expensive for only using it in a camp stove. There are cheaper versions of those 'brake cleaning' sprays (Bremsenreiniger) but the prices are still very high with aprox 3,5€ per liter. So instead of using car gas or brake cleaner, the Aspen 4-Stroke could be an alternative (but also costs nearly 4€ per liter), those Aspen ist kind of biological ethanol. Kind regards
