question on british fuze

Hi all,
I am currently researching the weight of explosive inserted into the fuze N°106 MKII and III, No. 44 II and finally the load weight of the gaine No. 2 MkII used for fuze type No. 100. The documents in my possession, don't mention it.

thanks by advance.

Hello my friend,

Put water in empty booster cavity for fuzes, check density of Tetryl and Trotyl, and makes a calculation of approximate weight.

Sorry, maybe you need official weights. Wait for Bonnex and TimG.

Cheers
 
Lol, thanks a lot. I will wait for Bonnex or TimG. You're true.

Mygale,

I've searched all the documents and drawings that I have and there is not one mention of the weights you are after. Unfortunately, calculating the volume and multiplying by the density of C.E. is open to error, as in the case of the No. 44 fuze the C.E. pellet is pressed in a 2 tons per square inch and I would think this would have a noticeable effect on the density.

Hopefully, Bonnex (who has a vast library) will be able to assist you.

Sorry, just seen this. I guess the info is not readily available in Treatises etc. I will see if I can find anything in committee minutes and handbooks. You will appreciate that the energetic material in fuzes can include small detonators, stemmed explosive, and pelletised magazines with variations in density and thus weight. Minenaz16's approach, or an AutoCAD equivalent, might be worth doing since I am not confident that my references will deliver anything useful.

Best,
 
Apologies Tim. Just seen yours too.

Having a bad day!!
 
Bonnex,
thank you again for your engagement. I know this is a difficult search. Thank you in advance. Also thanks to timg.

Dear M,

Clearly my library is not vast enough - no joy yet. Your question has highlighted a surprising lack of data on British fuze fillings generally and, given the need for such information for technical purposes, it must be documented. We will locate the figures but meanwhile I add the query to the ever growing list of things I don't know.

I assume you have tried French records. I say this because I understand that a French company made quite a few 106s for us.
