Scale Repair Progress - April 2, 2026

Shows how the plywood is affixed securely within the steel angle framework with both nutted fasteners and a heavy dose of some form of mastic or liquid nails. Had planned on replacing the plywood but the extraction process is formidable to say the least.

Another picture showing how well 'assembled' the plywood decking is of the scale's platform

Balance chamber or Shot cup of the Counterpoise Hanger. Was empty. Mostly a curiosity as this scale is only interested in difference between pre and post fills of the liquid nitrogen dewar.

The room this Dormant Scale is in. The fill room with this scale is next to the larger open roof ONYX LN2 Tank.

After shearing off one screw that held the platform on the scale this was the first attempt to repair it, a slot was Dremelled in the remaining screw and a flat blade screwdriver was used to attempt to unscrew... This did not work.

This is the corner of the Lever system where a bearing/saddle had slipped off. This is the heart of the repair that was performed today.

This shows the small gap that is needed between the platform and the surrounding floor. One possible cause of the slippage of the bearing was the scale's overall frame had shifted causing the platform to push its lever saddles out of place.

Second attempt of sheared screw repair, drilled out broken fastener and retapped 1/4-20 thread.

See title, the Dormant Scale before any repair work.

Inventory sticker. Might be useful for tracking down age of this scale or era in which it was first installed.

First glimpse of the internal levers of the scale after the platform was removed.
