CONE TRIAL 2

I looked at the option of adding a bracket guide to the metal roller but there seemed nowhere to mount it so that idea needs more thought. The man in the video also tightens one side of the top roller more than the other to achieve a tighter radius at one end of the metal.
I tried rolling the intake tube-the convergence on this cone isn't very great and it's very close to a standard tube-This was fortunate because of the length of the metal, there was a large amount in contact with the rollers making it very hard to twist straight to form the cone in the rollers. This wasn't too much of a problem because the difference could be corrected using brute strength and tacking the cone closed before putting it in the roller again to neaten it out.
This has worried me for rolling the exhaust pieces though as they are the longest pieces and have a greater convergence so will be difficult to make into a cone.
 The guide idea may need revisiting to help with this.

   

This piece also married up well to the intake flare (first test piece) which is positive sign.
