this post went a long time without being answered, so i will answer now, in case someone searches like me, and then ask my question
The makita 440 comes with a corse bag that you can put inside, WITHOUT a normal paper bag. this and the micro filter will filter most of the dust, but the micro filter gets clogged very quickly.
I only recommend using this where you have waste that is not airborne. I use it for my thicknesser planer, as the chipping go in the fire. for sanding, routing, sawing, i would say always use a bag.
however, (and now my question), i noted the brown "dual lined" bags went away for a while, and i had to get these white ones, which rip, tea, break, and are generally rubbish (no pun intended).
i see the brown ones here
https://www.dm-tools.co.uk/product.php/section/5697/sn/MAK83133B8K again, however at £36 (let's say £40 with delivery) that's £8 per bag!! i can fill a bag in a productive afternoon. that's £8 a day on bags.
Emptying them seems a bit of a coutner-productive step, as all the fine fine airborne dust will come piling out.... however i suppose if i did it outside, wearing a mask, holding it inside a sack...
then i have to seal up the bag again somehow, perhaps the bag lining is clogged, and i lose suction, perhaps the dust comes through where i tried to seal it, cos no tape job will be perfect, etc.... so does
anyone else have any experience with this?
Or just a completely different clever idea :wink:
