does anyone have any suggestions as to what an amateur pyrotechnician (i like the sound of it) such as myself should buy? i am not producing anything in massive quantities, and am only making basic compositions such as black powder. also, i am looking for something cheap. any ideas on whether to use digital or a triple beam balance?

im an avid ebay user, and was checking out the following auctions:
Ohaus Triple Beam Balance
or
No-Name Digital 500g, 0.1g accurate Scale (over, but there are many similar auctions)

any ideas or suggestions would be appreciated, thanks.

That last link is the exact same scales i use! I find it works great. I have also dropped it a couple of times, (when switched off!) and it seems to be ok!
All-in-all a good set of scales for the price!

I also have a similar scale like the the last one only mine is accurate at 0.05g and has a weighing range of 200grams

my suggestion is: buy the digital one, it's simple, accurate why bother witha manual one.

[Yugen-biki]

YES, digital one!

A decimal is very good to have. Maby not in the beginning as an amateur pyrotechnician but you'll miss it when you don't have it.

I have a 600g capacity scale with a resolution of 0,01g. It was worth the money!

I have differn't digital scales with differn't accurations.
100g-0,01g
5kilo-1g
There very usefull for weighting small and accurate compositions and for big compositions.
I'm thinking of buying a 500gr scale to, with should be atleast 0,1g accurate.

My opinoin: Go for digital scales .

I think both Digital and Ohaus Trple Beams Both Have a place in the shop. If you are playing with alot shimizu's formulae, which are nearly always to the 10th of a gram.....XYZ 13.5
............ABC 65.3, etc, the tripe beams offer resolution you can see, whereas digitals you are relying on a calibration you can niether see nor adjust except in some of the very high end digitals. I use a digital that I calibrated using known weights from the triple beams and it is 7 10ths of a gram off across the board. So if your serious about duplicating The Masters Work, you'll have to use the masters tools, hence the opinion that both are needed in any shop.....just my 2 cents.

I am looking for some more scales.. The one i have at present is a Ohaus triple beam balance 310 g capacity 0.01 g resolution.. i have had this for 20 + years..and works perfectly ,but i would like to be able to weigh in bigger amounts..

I have seen some of theses new digital scales on ebay they are very cheap but i dont trust them?...My GF has a set of digital scales that are suposed to measure +-1g resolution yet when i have used them for weighing my lift charge i weighed out 35 g i then took it off the scale and tried it again and it weighed 37g? then 34g? etc...also i weighed the contents of an orb rocket the same thing happned it varied by several grams each time.. this has put me of buying a digital scale?

Has anyone got a recomendation of a good cheap digital scale? ..i am only thinking about a new scale due to the cost factor..obviously i can buy a expensive scale that will be accurate but i am talking about these cheap scales you see on ebay are thay accurate?..a 1kg scale is what i am looking for

Just get a new triple beam. I have one that can handle upto 3kg's or so with the counter weights supplied. Very cheap at around ?100, and indeed very accurate to 0.1g.

Mine are made by Salter-Brecknell. A quick google brings up many suppliers of these types of scales.
