I have three large dust extractors, the latest I bought new at Christmas and only once tried to use it on my lathe.
It soon however choked itself on the stringy fibers produced when turning as the two four inch inlets which have an inbuilt caged guard on the inlets inside the both protruding pipes . My intention is therefore to make an in between seperator canister with two four inch pipes coming throught the top of the very tight fitting lid.This is going to be made from quite a large rubber heavy duty garbage type canister which I have never used for garbage.To describe it I would say as follows .That it is an expensive industrial heavy duty unit made from very thick rubber and is quite robust non bendable heavily made including the rubber lid.
The idea is to place the canister between the extraction point ( still to be made from clear plastic) at the rear of the headstock and toolpost but movable.
This will allow the heavy stuff when it reaches the input of the canister to drop to the bottom direct from the rubber canisters right extraction hose ..And continue on with the fine dust to the extractors bags on the machine itself.
If you approve of this design,or have made one please let me know?
Or should I use a smaller container?
I can soon make room for it as large as it is since it.s extraction point at the headstock will be at the side of the newly made extraction shroud ( I E not behind) this as said will be added to the right (since my lathe is close to the wall no room behind it for the extraction onto the new four inch hose without it kinking too much so it will be attached from the side right hand of the new dust shroud .Hopse this makes sense.Kindest regards Alistair
