Abstract: Provided are splices, comprising honeycomb cores and adhesive layers with tie clips supporting the honeycomb cores. Also provided are methods of forming such splices. Each tie clip includes two legs and a bridging portion joining the legs. When forming a splice, an adhesive layer is positioned between two honeycomb cores. One leg of the tie clip is inserted into the full cell of one honeycomb core, while the other leg is inserted into the full cell of the other honeycomb core. The bridging portion extends across the adhesive layer. While curing the adhesive layer, the tie clip supports the honeycomb cores with respect to each other and maintains their orientation. The tie clip becomes a part of the splice. The tie clip may be buried in the honeycomb cores without extending above the first face of the splice.

Abstract: A portable precision flange grinder grinds a flange on a duct. The flange has an axis, a radius, and a periphery. A mount mounts the grinder within the duct. The mount attaches to openings at ends of the duct. A grinding wheel grinds a flange on a duct and arranged to rotate along a periphery of the flange. A first linkage translates the grinding wheel along an axis of the flange to bring the grinding wheel laterally in grinding contact with the flange. The first linkage engages with the mount along an axis of the flange. A second linkage translates the grinding wheel along a radius of the flange bringing the grinding wheel radially in grinding contact with the flange. The second linkage attaches to the first linkage. A bearing assembly rotates the grinding wheel about the periphery of the flange. The bearing assembly is attached to the first linkage.
