    Most people think the carpenters were the first trade and the prostitutes claim claim they were first but it was the electricians, because when The Lord said "let there be light" all the cables and switches were already laid and there was Light.

    A shining example in an otherwise dull situation well done Tony.

    I thought I'd go for another milestone day ....after mowing the back paddock with the Victa ?
    l started the rebuild of the dust collector system and bought my first piece of 150mm PVC pipe work!
    Now I'm a reasonably intelligent man. I know that 150mm is 1.5 times bigger than 100 mm and that the area of a circle of diameter 150mm is 2.25 times the area of a circle of 100mm diameter BUT, when you actually see it.....

    it is BLOODY HUGE!
    My problem is that the inlet to the impeller on the DC is 125 mm and that this will remain my choke point until I go the 'upgraded 2hp generic DC route' or buy a larger DC!
    I have done some comparative flow loss tests and the worst offender, length for length, is, (not surprisingly)100 mm flexi. Surprisingly however, 125mm flexi is on a par with 100mm rigid PVC pipe. I haven't yet converted my machines to 150mm outlets but lm in deep withdrawal from woodwork and have even just been given a WW1 red poppy to "creatively display"?
    To get back into woodwork, I'm going to create a 150mm backbone, use the absolute minimum amount of 100 mm flexi to connect the machines but make it upgradable to 150 mm when I upgrade the machine outlets. I'm planning on using 100mm flexi ONLY on vertical drops or where needed for alignment. NO horizontal runs and NO 90 deg bends.
    I was quite intrigued to also measure that "100mm flexies ain't 100mm flexies" and there was a lot of variability in the test results. That beautiful, clear, VERY flexible flexi sold by Rockler with their dust right system performed the best and I THINK that is so because one of its features is that it automatically 'retracts' to the length needed when under vacuum and therefore presents a much smoother inner surface to the airflow?
    I've got bits of pipe, 150 mm fittings, salvaged 100mm fittings, gates etc laying on the floor so that I can work out what I need to buy to really get started tomorrow.

    Alan, Could you glue a flange onto the 150mm adapter to go on the dusty inlet and use some of Trevor's bogging skills to take up the gap, making a free flowing connection,.. I hope that makes sense?? Peter

    I'd thought about that thanks Peter and was even going to contact the 'bogmeister' himself but the entry into the impeller housing is 125mm AND then the short length of Flexi after the impeller to the filter/collector, is also still only 125mm?

    Although I know that I could throw time and money at it and do better, it will already be very much better than what it replaces. The runs are halved in length, 100mm flexi will be reduced from an average per run of 3 metres to less than 1 metre of vertical drops only AND because switching is now more accessible ....I will actually turn it on much more often!

    It has to be seen to be believed and then the light dawns as to why it flows so much air compared to 100mm.
