i am a fan of your work and have constructed two 5 gallon pail separators, so i know the baffle works. the added cones or salad bowls or wok/wok lids just seem to significantly increase the effectiveness of these single stage collectors so easily that it makes it a very tempting modification.
if a baffle were to be added instead, what are your thoughts on how to mount it within the dust collector drum? when i built my 5 gallon separators, the baffle was suspended from the bucket lid with 3 long bolts. any thoughts on how to mount the baffle to the DC drum?
