This falls into yet another “project I started over a year ago” category.  Not sure how it fell off the radar, but it did.  Dust collection is a wonderful thing to have, but there appear to be no standards.  Every piece of equipment has a different hose size.  I wanted to plumb my two main bench-top sanders together in a clean and easy way.

I started by adapting the back of my spindle sander to a PVC elbow, and then to a ribbed segment that would accept some flexible hosing.  5 minute epoxy is all you need to join the plastic pieces.

I cut a small length of hose and attached another hose coupler.  One side is ribbed to keep the hose from coming off, the other is smooth.  The hose slides on and off easily, but seals well enough to be a good vacuum.  I printed some mounting blocks that have a path through them to pass zip ties through.  This holds the coupling down without any complex clamp mechanisms.

Similarly I went to the stand that has my disk/belt sander and attached hosing so I could get to it on the side of the machine.

Now the vacuum built into the disk/belt sander can service both it and the spindle sander with just a quick re-plumb.  Cheers to less dust in my lungs!
