I have seen fellows sending out pictures with in the background, the DC hose duct taped and clamped to light fixtures, roller stands Music stands studs pipes and anything you can think of to hold it near when sanding on the lathe. Well the other day I was holding the hose between my legs trying to catch as much dust as I could when (could have been loss of oxygen from breathing dust) a idea sparked in my worn out old brain. ....
A while back I got an idea about turning 3" PVC pipe couplings to a taper to fit the quick connect on my 4" DC hose (so I could interchange the hose from machine to machine quickly, and cheaply) Why not a quick connect and hang it from the Tool Rest.... You don't need the tool rest when you are sanding. All safety rules say to remove the rest when you sand.
Today I picked up a 3" PVC coupling and found the old jig I made to turn them , and made another , affixed it to a 3/4" dowel rod and mounted it in the Tool Rest Holder
Here it is mounted behind the turning as if to sand from the bottom, but I will most likely use it in front as I usually sand from the top. Whilst writing this, my little mind sparked another thought... (Multi-tasking ) I think I will affix some 1/2" hardware cloth (Rat Wire) across the opening so my sandpaper doesn't get sucked into the DC. (I loose a lot of paper that way)
Now both hands are free to work and the DC can be place close enough to gather the dust and can be moved all about for different sized projects.
Okay, just went back to the shop and cut a piece of wire screen a little larger than the hole and forced it in place, snug fit and seems to work well, will keep from sending paper and pads to the Abiss...
Thanks for looking and and hope this sparks some ideas for you.
