I have a Fein Turbo II vac that I use with my handheld sanders. The problem is that it wants to suck the RO sander down tight to the worksurface and that impedes the sanding action.. Has anyone figured out an easy way to reduce the vacuum force of a shopvac in some sort of variable manner?
The only idea I have come up with is to put a splitter on the hose and partially obstruct the flow through the "other" inlet, maybe with a blastgate.
