Thanks John, already tried the aircraft people, pretty lucky around here we have an Air Force Base on one side of the town and a civilian airstrip and workshops on the other side of the town and then out towards the 90 mile beach there are ESSO helicopter workshops, so there are plenty of aeroplane "mechanics" around, and there is another fellow who collect's old aircraft parts to sell on eBay, he has some amazing stuff, radial engines and instruments and airframe parts, anyway to cut to the chase, most of the aircraft bolts are not suitable because they have very fine threads and as yet have I not seen any of them with Screw/Allen key heads, and most of them are just the wrong size
