Topic tags/keywords: question

Can anybody please identify by brand and part number a dust extraction hose adapter that will allow me to connect my 2.5” Craftsman vac hose to my various tools (DeWalt and other) with 1.5” OD extract ports? Or even a complete hose. I could leave a hose adapter fitted to each tool and utilise the standard Craftsman hose or use a specific hose on the vac when needed. Thanks in advance.

Sorry you’ve been waiting so long for an answer. What I’ve done with a couple of my tools is to use a craftsman 2.5 to 1.25 adapter and wrapped the 1.25 end with 2” wide electrical tape to get a leak free fit and run a couple screws through to hold it on semi perminantly. Another possibility would be to turn a bushing on your lathe to fill the gap or even a complete adapter.

If it’s a machine cabinet, I’ve cut a craftsman hose coupler in half to make two “adapters”and glued them around the smaller ports. Better yet would be to cut the hole on the cabinet bigger to not restrict the air flow. Hotmelt glue works well for this.

If I knew what specific tools you’re having problems with, i may be able to be more help.

Thanks for the input. My garage workshop has to cope with woodworking and golf club making which is another hobby. Thus my issue re extraction port sizing covers a DeWalt DW705 miter saw in the woodworking section (my Ridgid TS3650Table Saw accepts the Craftsman hose) and a Harbor Freight Belt Sander in the golf section. Both have a 1.5” OD extract nozzle. I also am in the process of constructing a downdraft table with Rockler parts to go under my chop saw as I cut graphite shafts which make a lot of dust.

What I have done so far is to determine that, for reasons of cost and space, I want to use my existing Craftsman 16 gallon wet/dry vac as my primary dust extraction. I have just last weekend built a copy of the Rockler Vortex as a separator and that has also given me connection issues, but I knew of those when I started. The Rockler Dust Right separator components only come in 4” and would not suit me even if I used an adapter which Rockler don’t seem to make. The connections on the Vortex (which fit a Craftsman 2.5” hose as I tried a coupling adapter in the shop) are 2.5” but Rockler Customer Service advised that you cannot buy the connections as a maintenance spare, even though they screw on so are separate, so you are stuck.

What I did to solve the problem in both cases was to use plumbing parts. For the Mitre Saw and the belt sander I needed Rockler 2.5” to 1.5” Adapters, Item 42248. I mounted these onto the relevant tools with a plumbers flexible sink drain connector. This is designed for a 1.5” ID metal sink drain and is a neoprene sleeve with two worm-drive circular clips, one at each end. This was a little tight (no bad thing) but slipped fairly easily onto the adapter and the extract port and was clamped in place as a permanent fixture.

The 2.5” end of the adapter is a little tight for the Craftsman hose but a LITTLE work with some sand paper inside that end, or with my Dremel if necessary, will ease that enough to make insertion and removal easier, as long as I am careful to not make it too loose.

For the “Vortex-Copy” I used “PVC Schedule 40” pipe fittings in 2” ID sizes and thus ended up with another pair of the neoprene sleeve connectors this time labelled as for 2” pipe but they are slightly bigger to allow for the pipe wall thickness. This clamps to the plumbing pipe perfectly and a few turns on the worm drive at the other end closes the diameter sufficiently to make a very good seal for the Craftsman hose.

Incidentally my “Vortex copy” is a 30 gallon chemical resistant tank with lid which I got surplus. I used a hole saw to cut the lid and then through mounted the screw pipe fittings and PVC welded the bends etc. My copy is much more robust than the Dust Right unit and is mounted on a Rubbermaid drum dolly which I also got surplus.

This is the separator

This is the belt sander which has the same installation as the miter saw
