    Can anyone recommend a reasonably priced silencer burner cap for the Optimus 8R, or a practical DIY solution? I’m on a tight budget, and the prices I’m seeing on ebay are far more that I can spend.

    I hate to be the one to break it to you ...
    This is NOT a cheap hobby.

    :lol: You're right. I thought the initial purchase of the stove was bad enough. :shock: But maybe if I do some smart shopping I can save some money. So I take it, then, that you have no DIY ideas? I'm clueless as to whether it's commonplace to make your own or if the only option is to hemorrhage money.

    You can make them .I've made a cap free hand with a drill press. Not pretty but the stove burned.

    The inner cap could be more of a challenge. I made this from copper end caps.

    I can't seem to find a how-to on YouTube. Do you know if there are any there? Someone told me that there's a second layer under that main cap, which is what contributes to the silence. Do you have any pics of that on yours?

    BernieDawg did a write up here. In your search of silent caps you will find his mistakes and his solutions.
    He was breaking ground with his innovations.
    So, you can do it with brass, silver solder and drilling, lots of drilling.

    @Dorraine Stanley , there are 3D printed silent caps for the 8R, $26.58, which is REAL reasonable.

    www.shapeways.com/shops/berniedawgshop

    Either the Minicap w/o legs or MiniCap w legs will work on a 8R.

    You don't even want to know what his original silent caps are worth now, hand made, and serial numbered!

    quietstove.com is another seller, theirs sells for $39.99, I've got one here on a M1950 stove, also works very well.

    @snwcmpr, I'm embarrassed to ask this, but since you mentioned those types of metals, I take it that it's not recommended to make a cap out of the ole "cat food can," like some folks use to make alcohol stoves. If I can't, then I'm sure I'll skip trying to make one, altogether, being my metal bending skills are non-existent. :content:

    @Murph, wow, yeah. $26.58 is a much better price than those I've seen. Thank you for the lead. I'll check it out.

    No, @ROBBO55, no lathe abilities here. I'm just an old housewife. :content: The pics in that thread are awesome. I'm always amazed at folks who have the skill to do stuff like that.

    @snwcmpr, thank you for that link. I did a Search a little while ago for "silent caps" and came across this very heading. Sooo much information here! This will replace my novel for the next several days.

    I know it is not for everyone. But, it gives an idea of what it took to make those handmade caps. They were the design that the CNC made, then the 3D printed caps came from. Possible, but no easy task.
    Easier to buy a 3D printed one.

    @Dorraine Stanley This is not what you want to hear, but...

    The silent burner on the German Enders 9060 military stove works well on the Optimus 8R. So all you have to do is buy the Enders stove.

    See, there is a practical advantage to having the stove pox.

    You could search for an Enders 9060 silent burner, though that's definitely a long shot.

    Best of luck.

    All I gotta do is buy another stove. Problem solved. :lol: See? You folks really do have answers for everything. I like your way of thinking. :clap: So I'm Googling it now. I also have that silencer saved in by ebay searches, and I'll keep checking the prices. Thanks, @ArchMc.

    @ArchMc Maybe - maybe not.

    Perversely I went the other way with one of my Enders stoves as you'll see from my display image. Was silent, now a roarer and yes I have a spare silent burner but I want it unfortunately. To make matters worse, I recently bought an Enders 9061D (silent burner) for £10 plus postage which is silly money! There are bargains to be had but you need to be patient and lucky (and have friends who alert you when something turns up!).
