Having today sorted out some shortcomings with my dust extraction system , during which I happened upon a new local souce ( see www.Lindab.co.uk ) in Chandlers Ford , and have swopped a rubber 6" to 4" reducer for a galvanized metal one , I am now considering some proper blast-gates to replace the lemonade bottles shoved up my 4" tubes . Does anyone have an opinion about the plastic ones from Ax ? they look ok in the website and seem quite cheap .
