    Now another mod in the pipeline is Leda sander.

    ideas suggestions please

    the belt should be relatively easy so of with a 100mm pipe split lengthways across the end and a bell mouth mounted to that, but the disc is another story, not that we ever use it much. well up to now anyway.

    Belt extraction has changed considerably but disc is the same

    hmmm bell mouth looks good for the belt. Going to test my talents making small metal brackets.. oh goody.
    But my disc is a different story, what a dumb place to run it from.

    Id say use the 100mm open pipe as you did just on an angle so it runs past the small pulley and cover up that small vent.

    Hi Bob

    I have been thinking about your suggested mod to the thicknesser hood. Sorry but I am crap at drawing. I was thinking of opening up the back of the existing hood, and running a full 6" pipe right along the back of the Thicknesser hood. Cap one end and extraction the other. I was thinking the 6" would have to sit high so you don't lose any depth in the Thicknessers capability, so toying of making one out of fibreglass.

    Any comments?

    Not without a drawing.

    This is about the best can do> i HOPE YOU GET THE GIST OF IT. Proposing to really open up collection chute, which would blow directly into a 6" pipe/chamber. Have to make sure I can make it fit, but that is the general idea.Thickness DC Proposed.png

    Yep I get it.

    I would not in the first instance make the end cap solid.
    Even if it was completely absent the Bernoulli effect of huge amounts of air rushing into the end cap opening and past the hood would drag most of the fine dust out of the hood AND grab any escaping fine dust from the vicinity of the thicknesser.
    However it is unlikely to collect the chips as effectively so a balance between the wall be be needed.

    One possibility would be to make the end cap an adjustable opening.
    This can be done with a blast gate or butterfly valve or any symmetrical set of openings that can be easily blocked off.
    In the first instance I would test this just using a piece of MDF or similar, to partially block the flow.
    Adjust the flow so that it still collects most of the chips and the rest is minus escaped fine dust collection.
    One disadvantage is any restricted opening will be noisy but is unlikely to be any noisier than the thicknesser.

    Thanks Bob, I will play around with it when i get the chance and report back. Won't be anytime soon.

    Having an adjustable air flow in that end cap could be really useful such as when routing MDF or very hard wood with cutters that make more dust and less chips and you would then use more flow through the end cap. Then for wood and cutters that make more chips you can restrict that and collect more chips.

    Like your idea of maybe using a gate to adjust airflow. Seems like a very simple solution. MDF on the router table can be a bugger, so need to give this some thought on how to implement . Above table OK, but below a bit more of a struggle
