Hello everyone, My wife accidentally dropped my Primus 96 stove (marked AB =1930), and now the tank is deformed near where the burner connects, along with some damage to the tip of the lipstick vaporizer. I would appreciate any tips on how to fix it. I was really upset at first, but what can you do? She’s my wife, after all! Thank you all, Migwar
To fix the tank, I would remove the burner bell and just pull on the vaporizer to straiten things out. Carefully gripping the vaporizer in a vice and tweaking on the tank would probably be easier. I've straitened a number of bent stoves this way. For the vaporizer, you can use needle nose pliers to remove the core mesh in the vaporizer, then use a smaller diameter piece of metal with a hammer to try and pound out the dent from the inside. Again, putting the vaporizer in a vice will help. You don't have to make it perfect again, just enough so the jet points up again. If you have a torch you can heat up the deformed area a bit so the metal is more pliable. Don't forge to re-install the mesh when you're done, it really helps vaporize the fuel.
You can use the burner as leverage to pull up on the fount, being careful how you exert force on the burner. Can use a bolt or two to open up the burner, being careful to only move a little at a time or you may split the burner. Duane
Thank you dears for your advices. I will see what to do. I went out to release the stress. It is really stressful to damage such a Vintage item.
Good luck with the repairs. The only thing I'd add is that even if the worst happens and the burner splits - there are still ways to resurrect the stove: https://classiccampstoves.com/threads/the-will-it-fit-96-burner-question.47240/ https://classiccampstoves.com/threads/primus-210-roarer-on-a-96er.15088/page-2
I agree with @Mikko. It is near impossible to panel-beat a crease in the top of a lipstick burner tube. It requires correct tools and skills. I know, because I've tried it and failed, and I've done a fair bit of fettling in my time. Note that the bottom of the lipstick tube is silbrazed to the hex. Tony
I may just be fortunate. I had a Primus 96 with dented vapouriser top and managed to straighten it out by grinding a bolt to the shape of the top of the vapouriser and then using a small hammer to do the job. I dropped the same stove recently and dented the vapouriser top again. It straightened up again using the same method.
That’s somewhat, what I use to also peen the burner. I’ve also had to silbraze one when I used a tool the wrong size and it opened up a small spot. Duane
I appreciate everyone's support. Given my abilities with hammers and bolts, and based on your suggestions, my first choice will be to seek out a technician if possible. I will emphasize the significance of the stove (vintage item and importance of proper functionality)to ensure they approach the task with utmost care, and I am hopeful for a positive outcome.
@Migwar agreeing with hikerduane & 907_nick Even if you get someone to help. I add to advice A. servicing damaged brass is unforgiving, proceed with care. B. PULL UPWARD on it... almost all the force you apply will be upward and slightly to the side (the damage is downward). do not apply force to the side trying to force it back upright. A BAD result of pushing sideways only can result in MORE *damage to the tank (vs correcting the problem). *the opposite side of tank could also cave in.
Hello everyone, I got the stove fixed today by a technician who followed our instructions. It worked fine initially, but during use, the flame started to weaken gradually. I let it rest and tried lighting it again in the evening, but this time, no gas was coming out of the burner. It seems something is blocking the flow. I’ve opened it up, cleaned the vaporizer, and pressurized the stove again after priming, but there’s still no gas escaping. I don’t want to damage it further, so I would appreciate any advice to avoid doing anything wrong. Below are 2 pictures for the stove after having it fixed by the technician. Best regards, Migwar,
Is the burner orifice plugged or did you clear that when cleaning the burner? Do you have a pricker for the burner to clear it? I find fine carbon can plug the orifice after other parts are cleaned or removed then replaced. Duane
Thank you. I attempted various prickers but had no success (note that by default the orifice was very small and no prickers were going through it and I was not forcing them). The opening is quite small and may be somewhat impacted by the deformation even after fixation. When I shine a light behind it, I can see the light. It appears that particles are blocking it after I ignite the stove as you kindly mentioned. The mesh has been cleaned. Is it feasible to quench the vaporizer? I mean, would it damage any brazing or soldering inside it?
Correct size pricker is one tool needed to operate these, can only flush the path. Can suck on the threaded end to maybe pull the blockage out, then flush with water or fuel. Duane
Don’t force a pricker through the jet. Use 0.19mm wire (guitar high e string) for a pricker. Shape the end first with fine emery paper to ensure no burrs). Tony
