I found a great old Primus 100. It works well and is very nice. But, how can I make it more quiet for use in camp in the early morning ? Thank you for your help!
The Primus 100 stoves are among my favorites. A silent damper cap can make your stove quieter, and also generate a better fuel/air mix for efficient burning.
Best choice is a Primus 4010 silent damper cap. They work super awesome on the 100s.
Base-Camp in England had some of the 4010’s a while back, but they’ve sold out of them now. Watch for a possible (though unlikely) return of the 4010 at Base-Camp sometime in the future, or ask around to some of the stove forums. Perhaps someone there would sell you one of their extras.
Another good choice for a Primus 100 silent damper cap is to fab up a cap adapter I call a spigot plate. I’ve made lots of these over the years. It’s a great newbie brazing project for anyone who wants to work on stoves.
Basically, you take a round piece of sheet metal with a hole in the center and braze a short piece of 5/8” diameter tubing to the middle.
The spigot plate holds the inner cap centered, and the outer cap settles around the inner cap.
Good luck on this project. It can be done with hand tools and an electric drill. You don’t need specialized tools.
