10 in to 4.5 in reducing flange on Laser Filter Cavity Input Cube cleaned of duct tape and 4.5 in blank flange added
I removed the duct tape on a 10" to 4.5" reducing flange on Laser Filter Cavity Input Cube. The duct tape is outside where the flange goes. I used clean wipes and acetone and then pre-wetted clean wipes with isopropanol to remove the residue. I then added a 4.5" blank flange and a gasket before tighteneing the screws to 13.6 Nm.
I tightened the bolts to 34 Nm so that most of the flange was on the zero length reducer flange.
