My RCA 816K restoration is now underway.

As I previously discussed, one side of this cabinet was severely damaged and my attempts at repair proved disastrous.

So, I opted to make a new panel using the original construction materials and techniques. This included a Poplar core sandwiched between two full sheets of Maple veneer using hide glue throughout. The decorative (QT/Book-matched) Walnut veneer is then applied to the exterior face, along with the baseboard (also QT Walnut veneered Poplar). I purchased enough Poplar for this and another much smaller project, which I tackled first. Unfortunately, the Poplar proved extremely unstable with the least ambient temperature variance resulting in extreme cupping, bowing and warping!

So, I opted to switch to Hard Maple and the results are much, much better! I opted to remake both sides so that they match. Approx. 2 inch strips with end-grains flipped. This time I used Tightbond II for the glue up. There was some very minor post-finish planning cupping of one of the panels, but laying it on the patio in the sun for a few hours convex face up quickly brought it back perfectly flat.

The next step is coordinate with a friend who has a vacuum bag system to apply the Maple veneer. I will be using Tightbond Cold Press glue. I purchased a nice glue roller kit from Rockler on sale: .

My photos are linked as an attachment. I am unsure how to place images directly on the post.

Once I have all of the structural work complete, I will be handing it off to Fred Taylor for decorative veneer repair and finishing. Fred is in Dallas while I am in Fort Worth.
