thanks everyone.
just had a reply from a company called spel-gate industrial in east yorkshire.
got to wait for a reply as i asked them about the same time s i posted this question.
they make any size belt, but if they are expensive i will definitely be ordering a ribbed one.
does anyone know where to get a flat drive belt for this planer.
i think its the same as metabo but still not sure.
it measures 570mm x 17.5mm x 3.22mm with a calliper gauge.
its a solid rubber flat belt( no ribs).
looks discontinued or out of stock everywhere i looked.
thanks
