I thought this might be of interest - it's a copy of selected pages from Artis Magne Artilleriae by the 17th century Polish inventor Kazimir Siemenowic.
I was particularly interested in the rocketry - rather more innovative than the congreves (though less suited to mass production and use), and also more appropriate for the period we're interested in...
btw the seagunner recipe for fuses is way too fast.
I'm just in the process of working out what I'll need in terms of engines, engine mounts, etc., to have a go at building some Hindu or Polish rocketry. Hopefully I should get them put together over the winter. I particularly liked these devices:
I was going to start off making them out of heavy card/balsa and see how successfully they work - if they seem to go OK, I might try building them out of something a bit more authentic.
They look very useful - thanks. I hadn't really got round to thinking about ranges yet - fairly modest to start with, I imagine, but if it all goes to plan then something rather more impressive after that.
Yes, why not - a bottle of port on the outcome? We would have to sort out something about weights, engine sizes and the like, but that sounds like a very good idea.
a bottle of port it is then. How about a maximum of an estes d12 (could require a bit of a big field 300yards, up to 1000 with a fire arrow), or c6/7 which should be restricted to about 100 yards. What do you reckon weight wise and do you think we ought to have a payload? (possibly a small smoke cannister)
by the way, did you notice that the polish rockets look very much like the cannister is made from a fabric or at least wrapped in it? (have a look at the tops and bases)
Maybe if we start with the 'c' size, and then try something more ambitious if that goes to plan (i.e., we don't end up in A&E)?
Yes, I was wondering if it was stiff paper/parchment/tarred cloth - it certainly looks to have been twisted together and tied. I was trying to work out how to make something in a similar way that would be sufficiently rigid. I think a few experiments might be called for...
I've used sodium borate as a fire retardant in the past, and it seems to be quite successful. The 'fuse' rockets do look the part, don't they? I think some playing around with ideas might be in order...

Can it be modified to make it useable?

arrow specs
34" 5/16" port orford cedar shaft with two 4.5" fletchings. estes engines were used
1/4a3 @ 20 degrees from vertical 20 yards potential range 50m
b4 @ 30 degrees from vertical 80 yards potential range 300m
based on these a d12 should get between 800 to 1000 metres.
Will try a c6 with a smoke canister next.

replica fire arrow construction for model rocketry

what sort of range are you thinking, I'm itching to try some live fire arrows on dartmoor.

possibly a fabric/pasteboard combination. Would potassium alum stop the flame sufficiently to prevent burn though ?
check out the visco fuse rockets here, they appear to have a similar construction.
