Reducing shop vac suction

[transatlantic]

My shop vac is stopping the sander from smoothly gliding along the workpiece, too much suction. I know the festool vacs have adjustment for just this issue. Is there anything I can do to reduce the suction on my vac?

I know house vacs tend to have a hole in the tube for this, but looking for ideas on how to adapt my flexible hose.

Best way to do this without causing a permanent modification would be to add in a suitable sized piece of pipe. Drill holes in this pipe to relive pressure until you get it just how you like it. If you need slightly higher pressure you can always block the holes again with a piece of tape.
I also need to do a similar modification for my own sander to use different discs. It works fine with abranet, but if I use the standard 6-hole discs then it becomes difficult to move.

Do you mean buy a whole new hose? I wish I could just buy the ends

Interesting that you bring up Abranet as I have just ordered some so will see whats that is like before making modifications.

No not a new hose, literally just a short section of plastic pipe that you put between the hose and the vac. Obviously needs to be the right size to fit into both.

Not sure what size hose it is, but I found a Rupes part # 107.502/C here when I was looking to do the same with a CTL Sys. Works well.

If you were to have a dig around, some smart-alec made a video about it ages ago...

HTH Peter.

Drill a hole in a suitable position through the male and female parts of the hose and adaptor.
Mount the hose on the adaptor to expose the hole as much or as little is required.

Rather than spend money :roll: :roll: :roll: turn a short section of wood to the required diameters, forstner bit the inside and drill leakage holes as required.
