Been round to inspect it and everything is fine other than it needs a good clean and oil,I noticed the feed rollers weren't working as they should be but semi educated guess told me that they had shavings under them preventing them making contact and feeding the board through, got it back home and I was correct, feed rollers now work fine.
I also found out from the previous owner (friend) that it is still on its first set of blades and only done two jobs in its life! 1, to build a clock case, 2, to thickens an old used scaffold plank, the blades have never been sharpened as the last job that had been put through it, scaffold plank nicked the blades and its been sat under its cover for the last 15 years or so, he bought it new, and was now selling it only to make room in his garage for his motor bike and hasn't had use of it since the scaffold plank.
