If you own the 1k sq floor house, consider a simple single track shelf above the doors and windows. An ogauger in East Tennessee built a twin track, wide curve arc shelf in his 14x16 Condo Den as shown in the faded footprint below. He had just bought MTH's Clinchfield Challenger and wanted curves of 080s-090s. The face of his plywood corner cut is 072.
Many others in the same area around Kingsport, Johnson City ,etc, built much smaller-arc, single track operations following the same general plan typically in bedrooms of 10x11,11x12,etc. Many tunneled right on through the top of closets.
