Hi, I'm building a model aeroplane and require some 3/4 inch O/D aluminium tube with an I/D of 5/8 inch. Two pieces are required each 14 inches long. Also, two pieces of aluminium rod 5/8inch diameter and 12 inches long. I have tried around my home town of Southend-on-Sea without success so I thought I might try here. The main thing is that the rod slides in and out of the tube as it is part of the under-carriage. It can be metric provided that it is a sliding fit. Look forward to any replies.
