    Hi Haig, Greetings from 'Up Over' πŸ˜‰
    Basically I agree, Hedgehog had more projectiles but two snags-
    1 The projectiles were much smaller, at 1/72 you'd hardly notice them, the splashes would be tiny. I'll have to settle for the four 'dustbin' throwers.
    2 HMS Hotspur was never fitted with Hedgehog πŸ€”
    Anyway you'd probably come along with U-181 and sink me!😲
    All the best, Doug 😎

    Hi Doug, it may be more impressive if you used the 'Hedgehog' as that had a much bigger spread (more splashes). For your purpose the projectiles need to be heavier than balsa but able to float (but only just).

    Thanks Commodore,πŸ‘
    I'm going to use a 2V SLA battery, as normal for firing up the Glo motors.
    I was wondering about ignition time needed and burn out of the plug coil. Just have to experiment I suppose, trick will be to limit the amount of oxygen getting to the coil I guess.
    Was planning to mass produce the Depthcharges from balsa dowel.
    Maybe I could 'scoop 'em up' with my tug or fishing cutter😁
    Cheers, Doug 😎

    I am using the short thread glow plug. it turns out that glow plugs have a very fine thread. I think it is 1/4" x 40, National Extra Fine. Barrel is just K&S brass stacked and soldered up a few layers thick. I light it with two NimH for 2.4V and a micro switch stuck on a servo. You need to let it off quickly or it will burn up the glow plug. One battery seemed a little weak. I know it will work well for depth charge throwers. Depth charges themselves will just be lost.

    It takes a bit of time to reload.

    I never tried it, but someone suggested using premade ammo made from paper soda straws. it might work.

    You have to be careful with this!

    Hi Commodore-H,
    Only just stumbled across this again and realised we were on the same track with Glow Plug ignitionπŸ‘ I have a box of plugs left over from my Cox Glow Motor days and was thinking of using them for black powder ignition of the guns and depth-charge throwers on my destroyer. Thanks for confirmation of the concept.
    Still trying to get my brain round the auto-reload facility thoughπŸ€”
    Cheers, Doug 😎

    Hi WW, I don't have problems watching the stream either, just the downloaded version πŸ€”

    Hi Commodore, black powder may be freely available in the US (as are automatic weaponsπŸ€”) but Europeans are more conservative with such things, especially in the light of recent attacks!
    For instance, in Germany (I'm in Munich) fireworks are only sold for a few days just before New Years Eve.
    Any tips on the construction of your barrels would be most welcomeπŸ‘
    Cheers Doug 😎

    I have never had any problems watching the liner clip. Thanks guys for the pyrotechnic information - I have had similar thoughts and experiment with increased confidence! Back to the plot though - anybody know any more about either the liner or Renown?

    I have a firing gun on my asheville class gunboat. I live in the u.s. and i use the powder for the flash pan of blackpowder gun. it is readily available.
    You need very little and it makes a nice bang with flash and smoke. I wad it with a tiny piece of paper towel and ignite it with a glowplug. The barrel is spring mounted so it recolls back when fired to complete the effect. You need to careful when building and operating this type of thing.

    Hi WW! There's a lot of fascinating stuff on that site, πŸ‘ Search 'models' and you get a lot of interesting mini aircraft, cars, tanks, complete towns (e.g. Bristol!), ships, and some pretty ladies modelling this and that! πŸ˜‰
    Could get addictive!

    I'd very much like to know what they used for for the 'bangs'!?
    I recently bought some magicians Flash Paper for the guns on my 1:72 destroyer, and 1:128 Graf Spee and HMS Belfast, which I intend to fire using redundant glow-plugs from my helicopter days in the distant past.
    Wish me luck! Cheers Doug 😎
    BTW I managed to download the Renown clip and the Liner, but the Liner clip jumps and staggers with lots of artefacts so couldn't see enough detail to start identifying πŸ€” The Renown clip works OK πŸ˜‰
