Being a tad parsimonious, (it’s been said ‘tight fisted’ more than once ) I hadn’t changed the paper bags on my twin motor Camvac since I had it, which is at least ten years. I used to brush the grunge off them and when they split (often) I used to repair them with glue and brown paper. As such, the ‘gulper’ attached to Camvac dust extraction system wouldn’t pick up small bits of waste from the floor (dovetailing waste and the like, about the size of a sugar cube)
The other day, they’d gone past repairing and were fit for nothing but the recycling bin, so I put on some new ones.
Hell’s Teeth, the suction appears to have doubled and almost anything on the floor goes straight up the tube! - Rob
