Step 4A sneak preview
iImage Information

If you have placed the rough spokes at 90 degrees and 45 degrees, lay the other ring and centre on top and have a look. Well I just had to get my wife to come and take these pictures. At this point My brain started to wake up and I could see what the finished helm would look like. A combination square or a right angle triangle should be used to help position the spokes. This is where I determined the length of the spokes. They extend past the outer ring by 180mm approx. Depends on how savage you are with the next step !! ( I hope you have marked the centre of the center circles )
