Here’s this morning’s quickie tip. I bought vacuum hoses, fittings, extension tubing, adapters, etc. from a variety of sources over the years. Unfortunately, manufacturing differences often prevent a good connection, and the result is annoying accidental disconnects while vacuuming the floor – or some other operation. In my case it’s always been because one fitting won’t fit sufficiently deep into the other – and/or is too smooth to ‘grab’ properly. The solution is to carefully ‘rough-up’ a fitting that’s the right size, but too smooth – or re-size one that’s too large using sandpaper. In both cases I use care to sand uniformly around the entire perimeter. I use a folded piece of 100 grit sandpaper for both purposes – being careful not to ‘undersize’ a fitting that’s simply too smooth, or to reduce the size of one that’s too large until I achieve a good, full, snug fit. In both cases, the texture created by the sandpaper helps avoid the accidental disconnects.

I just used your idea of sanding loose fittings on a 4” floor hose that kept slipping out of the connecting adapter. worked great and it is not slipping now. Thanks!

Love your shop, love your stuff!

You have a good eye for detail.

Many of the LJs here are wonderful though lacking in knowledge and final detail. They think they know. However hey just don’t get it wonderfully absent true woodworking art.

Though I would love to have any better woodworker friends.

They are best!

Dave thanks for the tip. I was just using duct tape before, but that made changing fittings rather time consuming.
