This is the answer I got to my posting at the bugtracker regarding weight loss during the process of crafting a weapon:
"Yes there is supposed to be loss of material, and thus weight as the crafting process goes along."
"A loss of material"? Just to give you some facts and figures to visualize what he is talking about!
To craft a Claymore it takes 4 steel stocks which is equal to 64kg.
Now lets take some P&P and start calculating:
Non-alloyed steel has a relative density of 7.85 g/cm3. Taking the 64kg as the base and we will get a volume of 8,152.86 cm3.
64,000g / 7.85 g/cm3 = 8,152.86 cm3
Now lets asume that the steel bar is 2x4 cm.
8,152.86 cm3 / 8 cm2 = 1019,175 cm
So we are talking about a piece of steel with lenght of ten (10) meters!!
But back to the beginning. The final weapon has a weight of 3.5kg. Subtracting the weight of the handle which is 0.2kg equals up to 3.3kg.
64kg - 3.3kg = 60.7kg
"The loss of material" he is talking about is 60.7kg!! Or 94,84375%
"The average claymore ran about 140 cm (55") in overall length, with a 13" (33 cm) grip, 42" (107 cm) blade, and a weight of approximately 5.5 lb (2.5 kg)." [ source: Wikipedia]
So we craft a blade with an average lenght of 107 cm out of a bar of 2x4x1000 cm, whilst losing 95% of the material during this process.
Please reconsider you statement about the 'loss'.

Yeah, sounds a bit wrong :P Material loss after smelting (so during the metal->item process) should be pretty low (unless you screw up and have to throw the whole thing away).
Afaik molten metal would be used in a known quantity for e.g. a sword, and once you have that amount you are just reshaping it, almost nothing gets lost.
Saying so in the bugtracker would probably be far more useful than here though.

Erhmm ... We did, but both times it got closed and locked.

because they are probably duplicates of a secret entry

If you guys revealed new physical principles you might be right to keep it in secret until getting the Nobel Prize in Physics 2010, if not .. well *shrugs*

sounds like you are volunteering to join the team ;)
Any way if the first one was closed it might have been more appropriate to ask for a reason on irc in #planeshift-build or by query to the person who closed it instead of just adding it again. You could even have made your arguments in a request to reopen the first one using the mechanisms provided by flyspray.
I do not always agree with the decisions taken by the developers, myself, but I do not repost bugs that get closed as if it will make a difference. They have the final say.
One thing is certain and that is the people available to talk on irc are not always the ones who have knowledge of any particular issue so being patient is a virtue while you wait to get things sorted out.
