Posted it as a project a couple of times and it was removed. I guess it didn’t have enough “wood” component to be a project made of wood. It does have wooden doughnuts at the top and bottom. There are several others already here on LJ so maybe that’s why it got removed. Not sure.
Mine isn’t drastically different than the other ones. I used the same 8” x 2’ duct tubing that others used. I found a cardboard drum with locking ring for the lid that holds the 5 gallon bucket inside to make it easier to empty the dust. Found it at a garage sale for $2 which was pretty cool.
I did a sketchup of the cut for the duct to get the cone design.
I used Elmer’s Polyurethane glue at the spots where air might sneak in. To me that’s the weak spot of all of the other designs.
The thing works great. Didn’t take too much time – probably a couple of hours. Cost was around $50 not including the shop vac.
Using a fairly underpowered shop vac, but it still has good suction power (once all of the cracks/holes are plugged).
I really don’t need the 2” union and some of the adapter stuff at the top since I just ended up sticking the hose to the vacuum right into the pipe anyway. Maybe just a single reducer?
