Are you welding 2 pipes @ 45s? If so i'd weld on flanges to the ends and use an elbow.

Mark the angle on a piece of wood, cut that and use it as a guide to cut the angle on your pipe.

elastic band at an angle? mark the high and low points on opposite edges and trace the band

Do you own any of the triangles that you get for tech graph etc, one of them with a long steel ruler and you could mark off it.

how is your tech drawing? you could develop it out on the flat. Any half decent tech drawing book will show you how. Even easier in autocad and printed one to one. A bit like this





Cut the shape developed out, wrap it around the pipe and it will give you a 45 degree angle.

Thanks for all the tip's I was talking to a lad today and told me about placing the pipe into water at 45 degree's (with set square tied onto pipe) mark the line of water and cut, well after that I went ahead and done it perfect job.

Very good. I was going to suggest using a projector
