Dust collection question - I'm sure others will have experience and some ideas to help me. I have a small WEN band saw with a 2 inch dust port. I have a 1 x 30 Central Machinery (Harbor Freight) belt sander with 1 3/4" dust port. I'm considering a spindle sander with 1 1/2" dust port. This might be a rhetorical question with no good answer, but this all seems really stupid - why don't the makers put on standard size dust ports? I have a ShopVac with 1 1/4" hose connector.

So my real question is how to deal with this, and adapters that will allow me to hook the SHopVac up to a y of the tools.

I have been looking at one from PeachTree Woodworking, a stepped rubber one that appears to be intended to cut off at different sizes - 2 1/2, 2, 1 1/2, 1 1/4 and 1 inch external diameter, with inner diameter being about 1/4 inch less than outer.

Any ideas or suggestions on better adapters?

This is the PeachTree one on amazon, I intended linking it but forgot

An alternative would be go to the local "Box" store (HD, Ace or Lowes) and get a simple fernco reducer - plumbing section - and get one for each machine to reduce  to your needed dimension. Then you would not be constantly moving the adaptor for use, just plug and go.

Is an aggrevating issue for sure. I have a 2hp/double bag from Griz with 4" hose so have chased the adaptor issue a bit. Which ever way you go I'd just adapt each machine to vac size and be done with it.

A thought - would be to use rigid adaptors to prevent hose/gravity drag that might collapse a rubber coupling. Good luck which ever way you go.
