   FG -

   I've made a few odd-ball connectors using aluminum flashing material and a few pop rivets. I wrap the flashing around whatever I'm making the fitting for and hold it with a couple of hose clamps. Add a few pop rivets, then wrap the whole thing in electrical tape to seal the seam.

   If you really want to get fancy, buy a crimper at the local big box and use it to add crimps to one end so it slips inside. Piece of cake, huh? - lol

     FG ,    See if you can find the correct fit in ABS at the plumbing supply , what you need in a standard dust collection or pipe fittings is a union or a connector to connect two pipes the same size .

   Jamie,

   Check out something called a "plumber's boot" - at the local hardware store.

   "Plumber's Boot" -- Ahhhh, I think that existed somewhere in my memory, but I couldn't remember what it was called.  Did you post something about using it a long time ago?forestgirl -- you can take the girl out of the forest, but you can't take the forest out of the girl ;-)

   Yes. It is a rubber device for joining odd types and sizes of pipe together. My Laguna bandsaw has an odd DC outlet size - the sales rep suggested the Plumber's Boot solution and it worked like a charm.Frosty"I sometimes think we consider the good fortune of the early bird and overlook the bad fortune of the early worm."

   Yes! A rubber thing with stainless clamps that will last forever even underground!

   Forestgirl--

   I'm not sure if this is the best solution for your situation, but you can buy an HVAC crimper to join sheet metal of the same size. This is a hand tool that puts crimps around one piece to reduce the diameter so that it slides into the other piece. It is very easy to use.

   I Googled "HVAC crimper" and found this:

   I bought mine at the local HVAC supplier. I'm sure they are at the big box stores as well.

   Thanks, Whit.  Seems like a crimper and a roll of good Duct Tape would come in handy!forestgirl -- you can take the girl out of the forest, but you can't take the forest out of the girl ;-)

   I did something similar, using 4" plastic sewer pipe (thin wall). Cut a piece long enough for your coupling, then cut it once along its length (I used my table saw with the blade barely  through the pipe wall and ran it along the fence with fingers well clear.

   Due to the width of the saw kerf, the "coupling" will fit over the same-size fittings, and you can secure it with hose clamps or sheet metal screws (wrap the outside with duct tape first to seal the saw kerf).

   This is more rigid than sheet metal (and cheap!)

   Hi, Kreuzie.  Might have to take a deep breath before trying that one, I'm kinda skittish around the table saw blade, but the fitting on the DC is 6" OD.  Plumber's boot might work if I can find one big enough.  Just trying to cobble something together for awhile without ordering online.

   I'll keep your tip in mine for other situations!forestgirl -- you can take the girl out of the forest, but you can't take the forest out of the girl ;-)

   Don't want to do that, eh?

   I mistakenly assumed you were dealing with 4" fittings...sorry.

   You could do the same thing, for a lot less than a dust collector coupling (plus shipping), by using a piece of 6" metal HVAC duct; do your cutting with a tin snips.

   Ask a HVAC supply house for a coupling for spiral duct in whatever sized pipe you have .All spiral duct is made big -end and the couplings are a tube that fits inside with a bead rolled halfway along the length to retain it.5" size are about $2

   Like this, Jako?View Image That pic is from The Blastgate Company which now carries spiral pipe, connectors, caps and such.  They also carry vinyl tape for sealing off.  Prices seem reasonable?forestgirl -- you can take the girl out of the forest, but you can't take the forest out of the girl ;-)

   Yes. The only negative thing is the slight frictional loss on the leading edge of going outside to inside  rather than inside to outside .But they work for me on 5 and 7 inch systems.

   And then we have sandpaper!

   Penn State Industries sells connectors for this. The page is here: http://www.pennstateind.com/store/premium-pipe-connectors.html

   I've used them on my cyclone connections and they are excellent.
