What do you put under your A&D scale?

Use a surface plate. $60 I paid for mine.

Nice setup. How do you like the Area419 plate and cup with the ATV4?

Before I retired we had a QC lab with several VERY sensitive and accurate scales. We solved the vibration interference problem by placing a HD plastic bag with about 3/16-1/4 inch thick of sand when laid flat on a sturdy lab table, then a 1" thick piece of granite counter top material on top of the sandbag. Vibration interference was a non issue after that. WD

Sounds like some of what I've seen done through the years too. I spent more than a few years working in pharma, and our labs all had an analytical balance or two that could read down to tenths of a microgram. These are often temperamental, and they are usually on either a thick granite surface plate, or positioned on their own individual marble benches. One of my favorite things to do when giving someone a tour of the lab, was to feed out a small piece of the thermal paper from the little printers that the balances used, put that on the pan, and zero it out with the TARE on the scale. Then I'd make an "X" on the paper with my pen, and return the paper to the pan. You could read the weight of the ink on the paper. Those balances are pretty amazing.
For those unfamiliar, the granite surface plate, or the marble bench, are there for the mass, and the dampening they provide. The equipment stabilizes faster with them. Static was a completely different issue, and one we battled regularly. Much worse in the winter, with dryer air. There were a number of little anti-static guns, and ionization field generators that we tried with limited success.
I personally don't think that level of precision is of value for reloading, but I like the idea of a granite surface plate for my scale. Mine is an older Mettler PB303-S/FACT and can read grains to two decimal places, with the second decimal place being only even numbers. That's way more than is needed, IMHO.

As suggested earlier in this thread I got a granite slab and a sorbothane anti vibration rubber sheet

I put my motorcycle lift under mine. Infinite adjustment. Reloading on one end, bullet press on other.

So... you seat bullets by raising the m/c lift?

50 bucks if you find the right counter top place.

The right place for sure.......I asked in Bend Oregone about 2 years and. That will cost you $280......

Not by hand because I have my scale on a large piece of marble. Very large. Really solid. Special. Huge, Very Huge. I hoist the m/c lift with my forklift to seat the bullets. It is a CNC forklift.

Of course.

What was I thinking ?

The surface plates arrived today from Grizzly. These things are great. They have near sequential certification numbers, and identical build dates, but they’re clearly from at least 2 sources of granite. Either way, they’re a great addition to the bench. Some serious stability here. The SuperTrickler is currently out for warranty repair, so the bench does look a little bare without it.
