Hi Ian,

Thanks for the info - any chance of a link to somewhere that would supply the fabric bellows? As for extraction I am considering two different approaches. 1) pipe with holes around the perimeter of the work area and another hose attached at the cutting head, both attached to suction and filter. or 2) box the whole unit in the corner of the shop and extract to outside with a big fan, allowing it to overun before re-entering the work area. each approach will be accompanied by a water table to contain dross. What do you thinks?

Thanks

Geoff
