Dust removal from power tools to dust extractor

Collecting the dust from my floor mounted power tools I have a nice two bag dust extractor, permanently connected to these machines by a system of four inch piping and valves. However up until now i have had to use a portable vacuum cleaner to collect the dust from the portable power tools that i also use.

so i had the idea to make connection that would allow me to connect a length of normal vacuum cleaner hose to my 4 inch piping at the blast gate. Having already assembled this one ill re do the build for you in line drawings.

What i used...

-- Wood square just larger then the diameter of the dust extractor hose/ coupling valve (6 inches x 6 inches x1 inch)
-- Band saw
--Portable sander (rigged up side down)
-- Drawing compass
-- Duct tape
-- long wood screw
-- Drill press (ensures vertical hole) or Power drill
-- Countersink bit
-- Drill bit to suit screw size
-- Posidrive Screwdriver
-- Drill hole saw
-- Pen
-- Straight edge

Step 1 Shaping the wood

-- Take the piece of wood, and place the blast gate coupling on to it so you can draw the internal diameter of the 4 inch pipe onto the wood roughly in the centre.(image 1)

--- Then using tangent cuts on the bandsaw cut down to the line. (image 2.)
