accurate scales for free

To construct a set of weighing scales capable of weighing to 99% accuracy at minimum cost.

I designed these scales 20 years ago. This construction allows you to test out accurate weighing techniques for buoyancy, ballast and construction repeatability, without having to shell out dollars for electronic scales, only to discover that the technique is not for you.

The following description, with the photo

Vman. Thats pretty cool....

What if I already have an accurate digital scale??? I save this to my computer as a reference in case of a thermonucular blast... Ooops, forgot about the electromagentic pulse effects... That idea is "TANGO UNIFORM".

Dave - Love to see someone making something out of nothing, I spent years going to the post office weighting coins so I could make a balance, to weigh my little 7 gm lures - I have now hit the big time, and bought a little electronic scale ($18), don't know how I got by without it. Great detailed work here.

Smirkplug- does this mean a $1000 note weighs 1 kilogram?????pete

Pete. I too finally bought a set of digi scales. Essential equipment to design. But the first six months of my lure quest was done on the above beam scales.

Dave.

A digital scale... What are you going to do in case of a thermonuclear blast... Did you forget about the electromagnetic pulse effects. How will you weigh lures then??? Ooops, I almost forgot about the original post - never mind.

Here are the images I still have on my computer.

 

Here is a link to the spreadsheet, or you can PM me your email address and I will email a copy.

 

I suggest have a play with the spreadsheet to get a feel for what it does. Find a suitable reference weight. Then you can contact me and I will help you through the construction by building in parallel with you.
