Ok here is my current situation .
In my woodshop I currently have three of the twin bag dust extractors attached to various machines with blastgates etc. One extractor is used for one machine, one outlet at a time. By using the blastgates to convert from one side of the extractor to the other.You know the type one bag over the other with a motor on a wheeled platform with double four inch extraction pipes attached down by the motor.
Here is my problem I have a very modern large lathe with a six foot bed fitted against a front wall near the front door of my shop.
It is fitted about a foot from the wall, which has a large window above the lathe bed the full length of the lathe which lets in plenty of natural light I love it.
I bought myself another extractor at christmas exactly the same dust extractor. I think off the top of my head they are all three horse power with plenty of reasonably quiet suction.I bought this to use purely for my lathe.
I never thought of a serious problem which quickly arose .With the dust extractor itself situated off to the side a little at the bottom tailstock end of my lathe. I excitedly fitted the new hose and brought it up by hand to the lathe where I do most of my bowl turning just to the right of my headstock,and as said over the bed.
I find ( quite annoyingly) that when I put the big mouth plastic nylon dust extractor accessory which looks like a large black funnel which sits behind the bed next to the wall and is adjustable to accept different sizes of bowl wood or spindle turning, though I don’t really see this for spindle work,anyway the bigmouth funnell sits nicely behind the toolrest ok but does not allow any room for a bend and a line of flexible hose together .
It just wont fit in .If you set it up with all this extra tubing and the bend of the tubing, it comes out far too far over the bed, leaving no room for turning as it occupies half of the bed caused as said by he large bend behind the funnel.I know many of you will say move the lathe forward a little towards yourself as you stand in front of the lathe and it will all be fine.
The trouble is I have made myself a number of time consuming special brackets which bolt the lathe to the wall behind it to stop vibration and eventual movement of the lathe.
It is as firm as a rock and I don’t wish to alter it and disturb my current set up as it works great.

I have the following idea and proposal to put to you guys for your input.I think maybe cutting a four inch hole in the wall behind the lathe and fitting the extractor directly outside with a nice plywood housing to keep it wind and water tight this would be the perfect solution all round as I now see it. first off it would take all the noise outside as I would insulate the housing outside to cut down on the not too noisy extractor making it very silent indeed.
Also it would make more room inside the woodshop, without the extractor.
I could make all the alterations to my woodshop making a small room in effect outside and wiring it all to be switched on from near the lathe inside with of course the new position of the flexible tubing now being taken straight outside behind the cutting area of the lathe as I use it currently.
I would of course make a door on the front or perhaps the side of the new compartment to empty the bag when required .What do you guys think of this idea and have any of you done it or seen it done what would be the pitfalls etc kindest regards Alistair

Just build a new box to the right width, with the 4” port on the side and throw the plasticy thing away.

I don’t know if your shop is heated, but if so, you are sucking all the warm air outside. Could use a return vent if necessary.

Yeah, what gamygeezer said. If you spend a lot of money to heat your shop, you’ll suck the warm air outside and cause dollars, er pounds, to evaporate from your wallet. Wouldn’t this little shed block your window?

I’m with joey….make a custom box that you can use with the current special attachments already in place.
Perhaps you can use some of the support brackets to support the box.
Of course photos are always appreciated.
