Help identifying some tools

Thanks Jay

The Bundenburg dead weight tester should have a matching set of weights. normally thes are paired to the tester. Unfortunatly they often go missing...
With the weights it has some value.

The weights for the deadweight tester will be flat discs, if my memory serves me right about 6 - 8 inches diameter, long time since I calibrated any gauges. Dave W

1985 was the last time I used a dead weight pressure tester.

You may find all sorts of good things in the filing cabinet, possibly the dead weights for the Budenburg, and other instrument as W I P which might benefit from the addition of the Drum Micrometers.

Seek and ye shall find!

I have a test weight for one of them in my scrap pile, if I could see how to upload a picture I'd put it on here so you can see what you are looking for.

Thanks for that Michael, I was trying to get the pictures to go up directly!

As promised 1 x dead weight

If the worst comes to the worst, and you only have one weight, it can be used to calculate the diameter of the plunger.

Once that is known, it should be possible to calculate the weight for each increment of pressure, and then to make new ones..

Alternatively, the easier calculations may be; knowing the weight that gives a known pressure, others can be calculated by multiplying or dividing and making weights to match the required pressures.
