Um. I never really set a price on them, but whenever it came up, always treated them as being similar to equivalent amounts by weight to plastic explosives, with prices varying by where you bought them (but always more expensive than last time, to discourage 'casual' use :rofl: )
If you've some baseline ideas, I'm all ears
Nifty Ideas, I like them
I'll put in an order for a few hundred meters of them.
LOL :rofl:

Linear Shaped Charge, Cr 250 per meter,
TDX, Cr400 per 2.5 kg
I would imagine this would provide something of a good baseline:
Linear burning rope, say Cr100 per meter or Cr800 for the package.
Thermeld strips, Cr 50 each
Hmm.
I'll run up a couple of equipment sheets for them in the next couple of days (PDF format), but based on what you've got there, let's say this:
Linear burning rope pack
Contains 1 x Linear Burning Rope (800cm x 6cm Dia, 5kg) c/w 2 x initiator pullcord plugs
Cr 800/pack. (7.2kg incl packaging)
Cr 150/metre separate length (0.625kg/metre)
Cr 50/Initiator (0.5kg)
Thermeld strip pack
Contains 1 x Thermeld Strip (15 x 5 x 3cm, 1kg), c/w 2 x initiator pullcord plugs
Cr 125/pack (2.2kg incl packaging)
Cr 100/individual Strip (1kg)
Cr 50/Initiator (0.5kg)
How does that sound?

Also - note the masses involved:
LBR is basically a derivative of plastic explosives, made to burn rather than explosively vent; as a result, mass-wise, it's fairly similar to PE.
Thermeld Strips include thermite in their chemical make up, which when combined with the properties of the binder/insulator compounds in the putty block, makes for an extremely dense material.
This'll be included in the kit sheets I jinny up, but please feel free to add that to the wiki if you want
Correction: IF I can get LibreOffice to cooperate in setting different widths to internal table borders, I'll ginny up a kit sheet, that is. GAH!

Very nice Redcap, very nice indeed !
The math here sounds off:
6cm diameter x 800 cm = pi * 3^2 * 800 = 22,600 cm^3 or 22.6 liters. Plastic explosive is 1.75 g/cm^3, so this weighs on the order of 40kg.
the meter length is 2.8 liters and 5kg.
6cm is about 2.3 inches. This is a big chunk of material. Given what it does, this isn't surprising.
If you make the rope 3cm diameter the 8m length is 5650 cm^3 or 5.6 liters and 9.9 kg, or about 0.7 liters and 1.2kg per meter
The strip is 225 cm^3, and about 400gm

LBR is 5kg for the 8metre length, initiators are 0.5 kg each, total = 6kg, not 7, plus packaging 0.2kg, total = 6.2kg, yep, maths was screwed, sorry! I'll fix that after work tonight on both the writeup on here and the PDF. I made the LBR that heavy deliberately, btw, since it's burning all the way, not just generating a massive shock wave, thus IMHO there has to be a lot more material component compressed in there to do the job 
Again, with the Thermeld, it's a lot more dense than you might expect, due in part to the thermite like materials, and also the heat insulation around the sides and top, that redirect the welding heat back towards the surface to be welded.
Hope this clears those aspects up
Again, Apols for the maths brain*arts, I'll fix 'em tonight after work

Thanks, but save the congrats until I've got it right
At least the blasted kit sheet layout was right, anyhow
My point was that a 8 meter length of 6cm diameter LBR should be 40kg not 5kg. A 3cm diameter version would be 10kg.
I'm at work right now, so briefly, the mass of an eight metre length of LBR, which is six centimetres in diameter, is 5kg; now, I'm not the sharpest tool in the box when it comes to dealing with figures (my strength lies in wordsmithing ), so if you can work out how much each one metre length masses, based on the above, I'd be obliged Note: LBR is not plastic explosives, so direct mass comparisons are not applicable
), so if you can work out how much each one metre length masses, based on the above, I'd be obliged Note: LBR is not plastic explosives, so direct mass comparisons are not applicable Fresh eyes, and all that - my apologies, I read it the other way around (lighter not heavier). And there's me waffling on about it being denser than PE, and bleedin' 'eck, 40kg per 8-metre rope?! WOW, that's bloody heavy!
Hmm. On somewhat more awake thinking, and consideration, and with fresh maths available (even with my appalling lack of abilities in that regard), I follow the logic, but still feel it needs to keep to being 6cm dia., due to it's stated purpose as being a different substance altogether, and needing the additional mass as fuel for the slow burn through the material that's having holes burnt through it. I could probably word that better, but this is slap-bang after a 10-hour shift for me
Right, maths of the first part. Figured out what I was doing wrong: I was letting the Cr 150/metre confuzz me. Helps to look with fresh eyes, I guess (did this earlier this evening and wrote it down so I'd remember it properly!). Mass per metre is therefore 5 (kilos) divided by 8 (metres), which gives us 0.625kg/metre for the 6cm Diameter LBR. Something over half a standard bag of sugar, in other words.
I'll take the 22.6 litres of volume you computed as read, thanks.
This then brings us to the thorny problem: Do we increase the mass, or leave as-is?
My gut feeling, given what you outlined above, is to give it the same mass as PE; you don't need as much PE to blow through a wall as you do for LBR, so the unwieldy nature of LBR will be confirmed even more by increasing the mass/metre, to make it a very much last-ditch substance to "do the needful" with.
So.
Using your figures above:
Mass per metre of LBR = 5kg
thus
8 metres of LBR = 40kg
Now, as you so kindly worked out the 8-metres volume to 22.6m3,
Volume per metre = 22.6 litres divided by 8 = 2.85m3 per metre.
SO.
WITH packaging mass and volume thrown in, we have the following figures:
Code:
Type Vol Wt Price
Linear Burning Rope-13 23.6 m3 41.2 kg Cr 800 / pack
(Packaging containing 8 metres of LBR & 2 x initiators)
Linear Burning Rope-13 2.85 m3 5.0 kg Cr 150 / Metre
(1 metre length)
Pull-cable Pyro Initiator-13 0.4 m3 0.5 kg Cr 50 / eachThe write-up on the pdf will read:
These updated specs will put to the PDF shortly, and reposted where it was before.
Many thanks for the pointers

I like the idea of the stuff. But I just thought, isn't 8m a long way for the circumference of a circle?
8m circumference would mean that circle would be 2.5-ish meters across. That's some 10 get across! Kinda big, maybe.
Then again, it's probable just packaged that long. Assuming the stuff still works when it's cut, and the two detonators that it comes with, it could be like a 2 pack of fiery glowsticks.
Can it be cut to length without too much worry? No player would ask, but... Interesting thoughts.

I figured it was close enough to the edge lengths of a standard single bulkhead doorway added together with a bit of a fudge factor to keep things conservative
Yes, it can be cut to length as desired (just like a cartridge of UK-standard PE-4, in fact!), or, you can add additional 1-metre lengths to it in a similar manner to putty or plasticine (or plastic explosives!).
Also, before you ask, the initiators are NOT reusable, they're one-shot jobs

Ah. I was figuring that if Bubba's Salvage and Fish Tackle was using these, they'd use these to make a grand enterance to a derelict ship. For a big door, 8m makes sense.
Hey, I'd have figured out that "detonators" usually don't survive use! I don't reuse blasting caps!...I've tried:nonono:
