Re: Report on $15 milligram scale

I use an extension arm made from balsa which gives a 10:1 increase in sensitivity. The fulcrum is the other side of the weighing pan from the item to be weighed so that the the load on the pan is 10 times the weight of the item. This removes any problem of static electricity generated by cutting rubber since the rubber is well separated from the scale. Works very well with my Gem Pro. The whole assy is a flat pack for easy transport in the toolbox.

I was surprised that moving the weight around on the pan didn't make much difference in the reading. Maybe Leo can explain why. At any rate I may try to make a larger pan and also an adapter to hang motors for weighing. I'm also considering buying another one or two of these for backups and putting my Acculab up for sale.

Thanks, Bill. That seems much better than what I did. i glued a small balsa platform to the supplied thimble, but it is still not stable enough and the display can be somewhat obscured. I'll copy you to glue on an adapter tube and raise and enlarge the pan, and maybe make two sizes of pan.

The link above is some info on the $15 milligram scale I bought recently. The scale seems to perform very well. The message above shows a simple adaptation I made to get around the problem of the tiny weighing pan.
