Anybody who is good at carpentry / metal working 10 points!!!?

Question

I am trying to build a measuring scale that will fit these requirements:

It should be able to weigh something

25cm x 25cm x 100cm or less

2kg or less

I am still trying to figure out how I am going to build this. I am not experienced in building contraptions like this. I do not have a lot of tools either. What kind of scale should I make (balance,spring, magnetic, electronic) and with what?

I am trying to do an important project alone so I'm just asking for a few helpful hints/ideas.

Answer 1

just buy a letter scale and use that as your muse for how to build one for heavier items.

Answer 2

Build a balance beam, you will need

1 board 2  inches sq  1 ft long

a 1 ft sq of plywood  3/4 inch thick,

1 safety knife blade,

a 1"x2"x  2ft long,

a hack saw , some nails or screws

nail or s***w  an end of the  2 inch sq board to the center of the plywood, with the hack saw cut a slot in the top of the 2x2

1/2" deep ,incert the safety knife blade into this slot sharp edge up. mesure the 1"x2"x2' for middle of the board, [flat side]

attach a small basket,pan,or something on each end, to hold a weight and what you will be weighing, find the balance point of the 1x2 and make a small score across the board with the hack saw, your done
