I think you can be certain its good steel, not made from resurrected beer cans, or old crushed Holden bodies. But be aware that what you remove from the inside, will have to span a much larger circumference going around the outside. So you lose cross sectional area using the same total mass of steel. But on the other hand, you have a much larger hole into which more turns of larger wire will much more readily fit. So its all a bit complicated. Only way to know is to go through the whole design exercise and work out if the numbers become more (or less) favorable after enlarging the hole. Many ways to skin a cat... I think its probably a good idea, based on the collective experience of many people here on the Forum that are seasoned toroid winding veterans. Edited 2021-04-12 18:08 by Warpspeed
