Starting over with this post. Images of the Primus 51 I just received. So, should I polish it up or leave it as is?
Hi Sparky, Nice stove you scored. As far as polishing or not, its a personal preference. I think if it was mine, I would leave the patina as is on the brass and cleanup the supports. How does it run? Thanks again for sharing and have a good evening, Dan
Hi Bob, You have acquired a really nice Pr.51, with a patina which has taken 62 years to grow and mature. I personally would preserve this finish, but of course it has to be your choice. Good Luck with the fettling and I look forward to seeing it in operation. Best Regards, Kerophile.
The stove arrived with no functional washers although the pump cup seems to work. I have not pulled the NRV yet. The burner tubes are very clean and the nipple is clear so I hope to have it burning as soon as I find a source of nitrile or viton washer material.
I have not put the gasket in the burner stem yet but the nitrile O-rings work well in the filler cap and the pump cap. The flame ring is a bit out of round so the flame is crooked. I can fix the ring on my anvil horn.
Hi Bob, I reckon the flame on your Pr.51 is too yellow. Try more pressure to get a more powerful flame and hopefully get rid of the yellow. If it persists try a new nipple. Best Regards, Kerophile.
Kerophile, Yes I agree about the yellow flame. I really just wanted to see if it would light and it did. The burner is badly sooted (outside) and the flame collar has copper salts growing on it. I did get the high temp washer installed last night and that seems to have stopped the leak in the burner. I have a kero nipple left over from the Monitor kit I purchased so I may swap it out. I need to raise the pressure now that the washer is in place. The sight of flaming kero squirting out of the side of the burner tube tends to stifle ones scientific inquisitiveness.
Hi Nice Primus 51 with brass legs one of the best discus stoves made. I would Leave it as it is and cook on it.
Here is the Primus 51 with a new nipple and one of George's high temp washers. Better pressure, better flame shape and better color. The first photo is just as it began to burn and the light is on. The next two are with the light out.
