Thought I start a new thread to document building the separator.
This is my first go at building one & this is this afternoons progress so far, I took plenty of photos as this was what I found sadly lacking in a lot of the information I found when researching.
Working on the principle that I wanted an air tight container to minimise loss of suction I managed to get hold of an airfreight drum made for transporting batteries.
I liked this drum as not only was it robust with a locking ring to hold the top secure but it also had a built in rubber gasket in the rim of the lid.
The first thing I did was to find the center of the lid for the connection to the extractor, this I did with dividers
With the center marked I drilled a 50mm hole, I also drilled a hole near the rim for the dust hose elbow, the fittings I'm using are 50mm mini gutter down pipe fittings.
With that done I turned my attention to the baffle, this is made from 14mm plywood, I started by cutting half way through the ply to outline a 14 inch disc the internal diameter of the drum.
I then measured round the circumference divided the measurement by 3 & marked this measurement on the edge of the circle, the router was then moved in 1 1/8 inch towards the center & an arc cut all the way through the ply 2/3rds around the circumference.
