I have this block clamped to the drill press table as it allows for 2 inches of wind up adjustment before I have to add another block under it but with a 6 inch tall mandrel it allows a reasonable ammount of sanding before the paper needs changing. I get quite a few bolster sets out of the paper for the horn bolsters but for the metal ones I still get three sets and it dosent take much to shange the paper. The spray adhesinve holds well and is reasnably simple to remove with thinners and a rag with a bit of a rub.
