I would think the fork tubes are 34 to 36mm so I think a strap wrench almost certainly would not work as it would not have enough circumference to grip and as the fork tube is probably polished chrome this would exacerbate the grip issue.
Luddites wooden clamps look like they might work provided the hole, before cutting the slot, was a good fit and the wood was a hardwood e.g oak, probably best also if the grain was across the plan view of the fork leg so that a decent clamping pressure can be applied before the wood splits
