You are right about veneered wood - it's a completely different issue. I think Rene's problem is involving solid oak used as the base of a machine.
Veneer was employed to give the appearance of solid wood, without the same cost. Usually the core wood that was veneered was poplar or chestnut or some other plain looking cheap wood. So, if that warps, the best option is to remove the veneer with steam, which softens the animal hide glue used at that time, straighten the base wood and re-veneer it.
If your method works, then that is another option - there is usually more than one way to accomplish a project and a little experimentation never hurt anything. Personally, I like to hear of all the different methods that people use to restore items, since you can learn from all of them.
