I picked this set up recently it’s got a homemade tin, windshield, funnel and a hot plate. It came with several spare burner parts which was a big factor in making me buy it. It’s on the bench for a fettle! NRV jammed solid and rounded off so I had o pull the pump tube out which is a bit annoying. I can never solder them in as neatly as they were originally. Unfortunately the seller had polished up some areas but not others so I will have to polish it up.
Looks awesome man! Desoldering a pump tube is something I have never done, and a little scared to try. I will once I get good with a few attempts. Looking forward to seeing how this turns out!
How does that trivet work? With the ''worm'' on top, it might get tippy. Inverted, and it might get in the way of the flame.
@SveaSizzler I will be honest I don’t know how the trivet/ hot plate works but the owner had thought about how to get more heat into the metal plate hence the “diffuser?” As you say it’s a bit rocky one way and the burner hits it the other way with the silent cap, it may not if you use a roarer flame plate, luckily I have one in my spares drawer so will try it.

Very nice, the home made additions make for a really special outfit. I've noticed people often concentrate too hard on adding solder... given the pump tube is tinned, and the socket it fits in is tinned, very often the surfaces will rejoin almost invisibly just by fluxing and reheating. I've never had to add solder to get a seal when refitting a pump tube, athough a couple have taken a second go with the heat.
I guess the heat would get trapped in the maze if the trivet had the smooth side up and enough space over a roarer burner to work.
The NRV removal and pump re install went well But the lipstick burner was way over sized so I did my first Hypodermic needle repair on it, which went pretty well and I now have a nice blue flame when using as a roarer. not so good with the two part silent damper further trial and error to get that going better is needed.
Another lesson learned today after many hours fiddling to try and get a decent flame with a two part silent damper including brazing a patch into one that came with the stove that was damaged by presumably under burn, I found I was losing pressure a dunk test proved my pump tube soldering was good as was the NRV But it showed up a leak in the side wall of the tank just below the filler cap the dreaded stress crack! That’s the end of that Primus 100 as a complete stove it’s now spares! The dreaded stress crack what a pity ! Several things learnt from the experience doing a dunk test as early as possible being one of them!
