Thread: Connections for Dust Extractor solved.

Thanks so much for this, Bob. Just for everyone's info, the Tradelink shop down the road from here (and I'm in semi-bush Western Australia) had the Adaptor Slab in stock and lots of the other piece too. He said they normally have them all the time, so it's probably worth ringing around to various Tradelinks before assuming that you can't get them in your State.

great advice
I've used about 3 rolls of tape for a dodgy fit.
Off to the hardware again. No tradelink in this town though.:mad:

I live in Moss Vale (country NSW for our non NSW friends) and whilst we have a baby Bunnings, no specialist plumbing suppliers. Went into Allen's Plumbing Supplies at neighboring Bowral, explained what I wanted and he showed me about 20 on a shelf ... I bought 3 to get me going @ $4.30 each.

Cheers,

Zoot Esq.

G'day, been away from the computer for a bit and have only just caught up. Above you mention that the flex hose fits into the coupling - I could be wrong but it is my understanding that the hose/pipe joins between the machine and the DE should be [machine side = inside, DE side = outside] - this should minimise turbulance and avoid buildups of dust etc. I hope this is clear enough.

Hi Bob
I understand what you are saying but I was not aware of the need to couple in the way you mention. You have probably done more research than I have.
I thought my idea would be Ok when using flexible pipe to change direction between runs of the PVC as the internal diameter of the flexible is near enough to the same as the PVC.
However I stand to be corrected.
Cheers

I think Bob has it right. Minimise the restrictions for best flow and your DC will work at it's best.

Adding a restriction in the middle of the pipe will cause accumulation of dust around the join edges and force the air to accelerate through that section, creating turbulence and lowering efficiency of the pipe.

I had a similar resolution to the attachment problem. I made "Quick Connects" by turning PVC pipe connections and making tapered connections.. I need to move my DC hose from tool to tool because my tiny Dust Bowl, all tools are moved in and out of a central play area. I purchased the Hose connection from Rockler but to buy the male connection for each of the tools would compound to a major Cash flow. so I devised a jig, to turn a taper on the fittings.

The 1st pic shows a faceplate base with a bolt to hold a core that snugs the fitting to the lathe. 2nd shows it mounted.
3rd shows the taper cut and the purchased counter part (female taper)
4th shows how they fit, Once I found the angle, I cut a Paper Template to duplicate the angle in future turnings.
5th shows how I also turned a shoulder to fit the piece to the Ridgid Thickness Planer DC head.

Just my solution to your problem, Hope it helps.

Nice one Hickory, unfortunately I don't have or have access to a lathe at this time [future birthday, Xmas, Lotto win.....hmmmmm.]
What I really enjoy about this forum is the variety of responses/banter [some comical] to common problems and the different ways people can look at the same problem - and the the willingness to share and help others.
I see you are in Kentucky and probably do not have the same fittings as we do - however if you need more info, I'll see what I can do.
Regards,
Bob

Yes I know it this an old thread, but I thought I would bring it to everyone's attention since it has recently been of great benefit to me.

Just needed to let you know that the Tradelink adapters recommended by Bob fit the 100mm dust collecter hoses almost perfectly. (if I was really picky, if the OD was maybe 0.5mm bigger it would be a snugger fit on the hose).

After struggling for a while to adapt the 100mm dust collector hoses to 100mm pvc, I read the various threads from everyone about solutions involving duct tape, rubber inserts, lots of silicone, and other ideas. I tried several different plumbing supplies and experimented with several different connectors and none worked. I even considered turning some custom adapters myself. Then I came across this thread.

Being in Melbourne, I went to my local Tradelink, who informed me they could not get them sent down. This must have been code for "could not be bothered for a $40 sale", because I went to a different Tradelink and they ordered them from Qld no problems. Arrived in a few days.

As I said above, fits the hose almost perfectly. So if anyone is looking for a 100mm pvc joiner, you have to try these. Cost about $6 each.

My lesson is if your Tradelink says they can't order them, don't take their BS, or try a different store that still remembers what customer service means.

John,

those connections are still in use and have survived the 40+ deg days in the shed,

Thanks, can't remember if that is one of the threads I looked at. Looks like you had to reduce the flange on the lathe.
The tradelink fittings work straight from the store without any adjustments necessary.

Realize this is an old thread but this may help someone. The local Tradlink didn't have the recommended PVC fitting (013145 Qld only) but the guy looked up another earthen ware to PVC coupling 030585 which will do the job as well. Only picked up one at this stage to try out - fits nicely up the flexible hose and is exactly the same size as the sewer PVC which is 110mm so will require a socket.
Cheers
