The reference plate, main panel and base panel are made from an aluminum-clad, corrugated plastic material. This material is very rigid, light-weight,
durable and flat. However, it is subject to dimpling under high-pressure, point-contact loadings such as that associated with the set screws which lock the dial indicator and pointer assemblies in place. The aluminum 'wings' provide a durable slider
surface for the pointer and dial indicator assemblies. The entire construction is assembled using aluminum pop rivets. See links below for the gauge in use and the resulting bumpsteer specifications. |
