Candle wax or floor polish is ok too as a release agent. You say dave may have crashed his pretty flash saito test stand? i hope not, in old age it can give you a bad case of ort, over revving ticker, which can cause loss of balance and a faint feeling, specially in a small shed eg; i know this fool who was on the third tank running in an fa115 when it suddenly went to full throttle and unbolted itself from the soft pcp, packing class pine, timber. At least once in our lives we've all been so instantly mesmerised and frightened that the feet won't move but your knees fail so you hit the deck and save yourself
in my case i fell behind a large lawnmower.
ps dave i hope you recover soon but if you don't...will you put up your membership number so we can all raffle it off over a few beers and some jokes at your expense ??
