TL;DR -- tips for uniform stain / color absorption in old and new oak on secretary desk.
I'm currently in the midst of restoring my great grandma's child's oak secretary desk (~100+ years old). I have it apart and have it down to the bare wood. This is the driest oak I have ever encountered. For context, I'm proficient in building and restoring furniture, but my experience is limited to building out of new wood and restoring veneered mid century furniture, so I've got the basics down. I've just never dealt with this old of wood. It seriously feels as light or lighter than pine. But there's no doubt it's oak.
Unfortunately, the legs are shot. Between warping and sanding, they're unusable in the restore, so I'm in the process of recreating the pieces out of "new" oak. Effectively, I'll have the old/original carcass sitting on top of a new base/legs. I'm going to (gel) stain and lacquer (given it'll be used by kids) and plan to do so in a darker color -- something like a walnut (grandma and great-grandma's favorite). The styling is also along the lines of craftsman, so it seems appropriate to go that route.
Ultimately, if all else fails I'm comfortable using toners to match, but I would prefer to be able to pick a stain color (Old Masters, or potentially General Finishes) and rock with it across the whole piece. But given my inexperience with the old oak, I was wondering if there was something I could treat either the new or the old oak with that would bring one in line with the other in terms of stain/color absorption? For example, something like wood conditioner on one or the other or both?
I don't have access to a humidor or a kiln to modify the moisture content in either. I've had to wet single sides of the old oak and let it dry wet side down to address some cupping.
Much appreciation if anyone has any advice.
