Thanks again Mike. It seems that it just refers to #8 as the motor so l might get in touch with the, regarding a replacement, if l can't get it fixed. On another note, if you don't mind, the table also has a router plate built in and l was thinking about extraction for that too. Ideally ld like to use my Nuematic Hoover under the table for both the table saw and the router. It would mean reducing the 'Axminster Big Mouth' from 100mm to 38mm and adding a Y connector to run another 38mm tube to the router extractor connector. To maintain concentrated airflow l would like to add blast gates in series with both but am struggling to find any that small. I could make some wooden ones but do you know of any manufacturers that do 38mm blast gates?
