Does the 2" cope with the chip?

If so, one possibility is to leave the 2" on there to collect the chips and add a 6" (maybe on a stand) so that the opening of the duct is positioned just above the wood on the side the cutter throws to.
Your flow rate is so high the 6" should collect most of the invisible dust that emanates from that machine

Thanks for the reply BobL. I haven't used it much yet so I don't have a real idea wether the 2" will be ok but if it is your idea will certainly save me a heap of work.

I have a combo thicknesser/planer, and have similar problems with the 4" line being throttled down to half that at the shroud.

I could convert the shroud to 6", but doubt I would achieve much as the machine itself restricts the air flow so much I doubt I'd get much extra air through the machine. Currently playing with a design that grabs a bunch of extra air form either end of the machine.

Does anyone know of a similar machine being tamed for dust collection?

Hi Safari
I have been following your installation with interest. Yours and Johns input has helped my installation immensely. Many thanks.
In your latest pictures you show several connections between 6"PVC and Flexible ducting. I am having trouble connecting 150mm (6") flexible duct over 160 OD PVC. I am sure I have read a post on how to do it somewhere but cannot find the post. Also how did to connect your ducting to the inlet of the cyclone. With my CV1800 150mm Flexi slides inside the inlet transition on the cyclone. Sealing this join so it can still be disconnected seems very difficult.

PS I have a standalone Sound level meter and will post some measurements when I get the power connected to my CV1800. My installation has filters on the outlet inside the workshop so should be the loudest situation possible. We shall see

Cheers
Ron

Ron,

There are a number of ways to do this. Bill Pentz recommends a very short length of flexy between the cyclone and the ducting, to stop vibration travelling to the cyclone. Now that my installation has been running for over a year I doubt this is necessary, but it does make it easy to disconnect the cyclone from the ducting if needed.

I thermoformed a piece of 6 inch pipe (made it bigger at each end) so one end would slide over the inlet and the other end allowed the flexy to slip inside it and be taped into place. see pic.

Again, to connect flexy to pipe, a number of options are available. One is to put a straight connector onto the end of the pipe and to force the flexy into this and seal with tape. Another is to expand the end of the pipe (heat it and force in a cool pipe to form a socket) and slide the flexy into it.

I did not try to heat the end of the flexy and slide it over the pipe, but with flexy that has not got metal wire in it (mine does not), that sounds a possibility.

Hi John
Thanks muchly for your reply. I just remeasured my cyclone inlet and the OD is 170mm. Can a sleeve be easily thermoformed from 150 to 170? I also noticed that the transition has been thermo formed from flat sheet and has a step where the ends overlap. May also cause a sealing problem. I think Duct Tape may have difficulty sealing it as the step extends along the side of the transition.

Also when you use a sleeve to slide the flex inside this presumably leaves a 10mm step on the inside. Does this cause turbulence or collect sawdust at the step that faces into the airflow?
Again thanks
Ron

Not sure. It sounds as if CV have changed the size of the inlet. A 6 inch pipe has an OD of about 162 mm, and would easily fit inside the inlet. Perhaps that is a better move. Shedman might have a few more clues, especially if CV have increased the size of the inlet.

I sealed all joints/steps like that with silicone during assembly ... no issues at all. You will know if you get a leak ... it whistles. I got one such leak. Re-taping fixed it in a flash.

I put a bead of silicon around the step caused by the flexy and smoothed it with a wet finger to make a ramp for the air to slide over. So far, no issues.

Hope this helps.

Instead of trying to stretch 150 mm pipe to 170 mm what about a using a stock connecting sleeve which is already 160 mm ID . Expanding one side to fit over 170 mm should be easier, and then the othe rside will mate neatly to the 150 mm ducting.

It's not ideal and will cause some turbulence that will also prevent sawdust build up especially but given the flow rates generated.

Ron, I have just had another look at the CV inlet and on mine it transitions from a rectangle to round. I can't remember what the diameter is but from memory it was quite close to the 162mm of the pipe so I just pushed into the inlet until it was pretty tight and used a lot of wraps of duct tape to seal it.Seems to have sealed it well with no leaks or dust build up. As for connecting the flexi to the pipe I found it a tight fit but with a bit of wiggling it will slide onto the outside of the pipe. I am using 150mm flexi from Purple Pig so maybe it is a slightly larger diam. or is more flexible than yours i am not sure. I just remembered that getting the flexi onto the bottom of the CV cone was a struggle but everything else was fairly easy.

Hope that helps. Now that I have got nearly everything sorted I, like John, am more than happy with the CV.

Hi Safari.
Thanks for the reply.

It seems like CV may have changed the design of their inlet Transition. I think I will have to try John Samuels suggestion.

What /where is Purple Pig?

Does the Purple Pig Flexi have a spiral wire embedded?

I obtained my Flexi from Stephen. It has a spiral wire and will not stretch over 160mm OD pipe. I would like to obtain a short length of more foible duct if available

Got mine from CarbaTec, and it has no wire in it ... just thickened spirals of PVC. However, I think (not sure) that the clear stuff with a wire spiral is a bit more flexible.

Hi Ron,

My pipe is a grey one and does have a wire spiral. I just remembered that I chamfered the outside edge of the pipe with a file which made it easier to slide it on.
It seems that Purple Pig has been sold to Powell Industries.

The new address for Brisbane is

Powell Industrial

Coopers Planes

(07) 3722 3722

(well, I hope that is in Brisbane)

Hi John & Safari.

Is it possible to measure the ID of your Flexi.
I was wondering if yours are slightly larger than what Stephen is selling

Mine (grey CarbaTec product; no wire; thickened PVC spirals) measures about 152-153 ID.

Just for kicks, I heated the end of a lump I had left over and pushed it onto a 6 inch pipe (the one that is not 6 inches, but is bigger). Two burnt fingers and one sore thumb later, it slipped on easily, see pic. Gloves are recommended. Then I cooled it, pulled it off, and slipped it back on again with only a minor fiddle. Now I feel like a goose for not doing that myself. If I had my time again, I would.

If like me you are doing this alone, have your bucket of water and wet rags within arms reach. It is necessary to support the flexy until it cools or horrible kinks are a possibility.
