This was a shop-vac mishap... I have a central vac with overhead ducts radiating to three extreme corners of the shop and one to the lathe room for the drill press, (two out of viewfinder) using 50mm PVC duct with hoses on each end. Being Bluetoothed, I can control the vac form the hose end using the remote. Saves dragging the vac around the shop cussing. My old Hitachi vac died and I replaced it with a Fe$tool CTM36... that sucker would gobble up a beach towel if I decided to sunbake in the workshop.
If your first cut is too short... Take the second cut from the longer end... LBD
