    Not really sure which glue to use. Hopefully somebody else does.

    I did not use glue in most similar situations. Rather, I fastened the two together with short self tapping screws.

    duct tape and small screws, dont use glue, because when you want to change things again your stuck.
    by using small button screws and then wrapping in duct tape all can be removed when wanted.

    This applies to ALL your ducting as well.

    I ended up using epoxy and rivets.

    Hopefully I dont need to ever change it. The orange bit is a 3D printed magnetic connector for the hose

    I am converting my planer next. I will print a BMH and stick it as close to the cutter as possible under the outfeed table. I will close that space off with some MDF so its sealed. I also want to use piping rather than hose for better airflow and will need a 45degree bend. I want to print my own 45degree connector - round internal but square external with mounting holes so its easier to cut out a square on the MDF board and also the mounting holes so I can screw it on directly. What sort of radius does the 45degree bend need to be as to not restrict airflow?

    I found an old post by BobL that says 2R is the ideal radius of curvature. Does that mean for a 150mm pipe that radius of curvature is 150mm?

    It gets described as Centerline radius. So I think 2R for 150 MM pipe would mean the radius in below picture would be 300mm

    Is 2R 2*R? Wouldnt radius of 150mm pipe be 75mm? therefore 2R = 150mm?

    Maybe it is that . I don’t know. I needed to know it a year or so ago selecting my pipes but it was described differently. I had a choice of 1 or 1.5 CLR I think . And I think that was 1 or 1.5 x diameter to give the radius .
    I just checked one of my 1.5 CLR bends and the CLR radius of that is 300 mm .

    Edit . Correction . I had a choice of 1 or 1.5R and I chose 1.5R. And my 1.5R bend I just measured (roughly ) has a CLR of 300 mm .

    Here’s the pic of the order form from Spiral duct Braeside .

    I just did 45 deg.jpga quick model of 45deg bend with 300deg radius for a 150mm PVC pipe - it looks huge!

    The Laguna is a delight to use. Dust collection works reasonably well, but not as well as the Trade Tools cheapie. There are a couple of reasons for this:
    1. The Laguna ia used for re-sawing and cutting veneers exclusively. Some dust gets trapped in the kerf (up to 360 mm deep), where the draught cannot catch it. Annoying, but not a big deal. This dust tends to drop onto the rear of the table and/or onto the floor behind the saw. The Trade Tools cheapie is used for thinner materials ... usually at or less than 50 mm. Its dust collection is beaut.
    2. The dust port in the lower cabinet of the Laguna is at the opposite side to the descending blade (where it cuts). The Trade Tools machine has the dust port directly under the descending blade, and this works a lot better. I may one day put a new port in the Laguna, but don't hold your breath waiting.
    Hi John,
    Is that 150mm to the machine, then 100mm after the Y?

    The hose under the table - how come you opted to not use the original hose outlet? Was it just to get it closer?

    Yes, 150 mm to the Wye and 100 mm thereafter.

    I do not understand the question. The machine hd two ports. One at the back of the machine that the 150 mm pipe is fastened to and one at the side of the machine just under the table which is now connected to one of the wyes. The original steel port under the table at the side of the machine is the one I am using.

    I think qwertyu is referring to the bit I’ve circled in the attached image.

    Ahhhh ... thanks DJ ... I had forgotten after the passage of so many years.

    Yes, I fooled around with the placement of that flexy trying to improve dust collection. In the end I stuck it on the steel port and left it there.
