I bought this lamp about two years ago, but somehow I was busy with other things and only recently got down to trying to fire it up. This lamp has a steel tank. I think it is a circa wartime production. (Please correct me if I am wrong.) Again with help came my friend @Piotrek , who gave me the mantles and needle, which he bought in Korea. I sanded down the edges of the needle a bit, giving it a conical shape, similar to the original. During the leak test, I located a leak at the connection of the pump tube that the tank. I soldered it up and it now holds pressure. I did a burner test. I put the jacket on and everything works as expected. Thanks for your attention. Regards. Stanislaw.
Good job @Knee I did not know that these lamps have some many interesting features - that preheating is really interesting, generator looks cool as well. Do you use kero or alco for preheating? Does it soot while preheating using kero? all the best, Piotrek
Hi Peter. Thanks again for your help. Good question. I actually depicted it in the pictures as it was intended by the manufacturer. That is, taking kero that the tank, with a special scoop adapted for this, integrated into the filler cap. However, having learned from the experience of preheating stoves, I abandoned this method, due to the large amount of soot and used denatured alcohol. Nevertheless, I appreciate the ingenuity of the creators of this idea because of the monolithic fuel.( for kindling and work).
@Knee Congratulations on the restoration. It lights up really well. My 506 is dark gray enamel, but yours is blue. I heard the blue one is older. Thanks for sharing. @Piotrek I have tried preheating the 506's preheater with kerosene. As @Knee said, it produced a bit of soot and stained the glass. If you don't mind getting the glass dirty, you can preheat it with kerosene, but I don't want to get it dirty, so I preheat it with alcohol.
Thank you @Camp numao ! My Ditmar has finally lived to see its turn. Thanks @JEFF JOHNSON ! The translator translated it strangely..
@Camp numao thanks for info. Now I see that you mentioned "It's easier to get a blue flame than the kerosene preheaters on the ditmar506 and BR49." while testing your Petromax 824. It seems that you have a special feeling to lamp with unusual preheating system
