    @plumberted was missing an inner cap for a recently-acquired CS56 and he asked me if I could let him have the dimensions, since he has a source to turn out a replica.

    I’m referring to one of these, on the left in this photo. On the right is my own fabrication for THIS project.

    Where it goes on the burner.

    Topped with the outer cap and flame ‘lift off’ prevention gauze, which the burner is otherwise prone to do without it.

    For anyone who can make use of them, here are the dimensions - in Imperial measure as manufactured. The material appears to be mild steel, forged rather than machined, with no machine marks, but a simple exercise in turning to reproduce and would be fine in brass also.

    No lathe, I fabricated the brass example from brass components, silver-soldered together.

    Thanks for the explanation. I would like to know how to braze and weld. I learned during my studies, but I never practiced afterwards, although I always worked in shipbuilding, but in offices. Sitting on a chair in front of a computer :mrgreen:

    Would you happen to have the measurements for the outer cap also? I just obtained one of these stoves but missing the inner and outer caps.
    Thanks, Matt.

    I had an original cap to work with when making a copy for a second CS56.

    I didn’t bother machining those crenelations/notches in the base circumference of the cap, seen on the original cap on the right. I guessed that combustion wouldn’t be affected (which it wasn’t) and if it was I could add them.

    135 holes of 1/16-inch diameter in 9 groups of 15.

    Gauge of metal (purchased as Metric stock) was 1.5mm tubing and 2mm thick disc for the top.

    The tubing was oversized in diameter and I’d to ‘cut and shut’ it to get it down to …

    Height.

    Thank you so much for this information. Looking forward to fettling this stove to working order.

    I'll provide pics of the process.
