This is really a Wheelmen type question and I would seek advice from that organization.
I happen to know that Jon Sharrat, the Minnesota captain built a steam box for the purpose of fixing wood rims and he could be a good source of information. He does other things like build wood strip canoes and thats the level of expertise required, especially if you plan on riding the wheel. Here's a link to a listing of Wheelmen captains:

I don't think its a good idea to depend on "pulling" a warped wood rim over to correct a warp. Wood rims are kept at a low tension. Thats why they are often tied and soldered and the spokes treated so as not to unwind.
Definately seek experience before attempting repairs.

> I've got a 28" wood rim( off a 1898 Orient track bike) that is
\r?\n> about 3/4" to 1" out of true and has the beginnings of
\r?\n> separation on the finger joint. The spokes are rusty and shot.
\r?\n> Do I cut out the spokes, wet the rim with water, inject the
\r?\n> finger joints with Elmers and put the whole thing under a flat
\r?\n> weight on a flat surface for a few weeks?--or could a good
\r?\n> wheelbuilder pull the whole thing to "true" when respoking? Who
\r?\n> might do such a repair. I hate to cause more damage because the
\r?\n> wheel wood is otherwise in good shape. Art Link in sunny San
