Two Bolt Flange Bearing
Three of these units arrived today. They will hold the far end of the shaft that extends the drive motor shaft from theBBAstro drive unit (Mel Bartels’ hardware). Shaft bore is 1/2-inch and there are three because the altitude drive will have shaft extensions from both ends of the drive shaft allowing us to drive both sides of the rocker box at the same time (design image is coming!).
