poyton phil I was simply using it on a cheap ceramic tile, had been asked to "write" someones name through it which is easy with the rotozip. wasw getting to the end of the name then sparks and smoke belted out of the top, I hit the off switch but is still kept on going. Pulled the plug and through it in an empty tin bucket.
I have the Project centre without the storage box, the one I have is either a Market Trader style trolley that turns into a table, I know the one you mean but this is different, no storage at all.
