I just attempted resawing some thick 4/4 x 6" x 4' Oak. I had bought it rough from the lumberyard, so I jointed, planed it til it was a straight/consistent 15/16".
I then set up my band saw (1/2" Timberwolf resaw blade, Kreg resaw guide) to resaw into two 3/8" slices. It worked pretty well. I then sent it back through the thickness planer (band sawn side up)to clean up the surface and get back to a consistent thickness. Now I notice the two boards again have an extemely noticeable bow. Remember the original rough 4/4 board did start with a bow.
Questions:
Is it normal for a board that had a somewhat noticeable defect (such as a bow) to exhibit this again after the resawing process?
Should I have allowed the "resawn boards" time to reacclimate themselves to my shop before doing the finish planing? Will stickering it now help?
Should I have resawn the lumber in their rough state and then started the milling process? How much more difficult is it to resaw Walnut than Oak (I have a Taiwain import 14" BS, no riser, 1 hp)
I consider myself a novice woodworker. In the past I just joint/plane my stock all the way from 4/4 down to 3/8" or 1/4". It just seems such a waste(not to mention the abuse on my thickness planer blades). The cost difference between 4/4 and 1/2" lumber from the lumberyard is about the same due to the milling charge they impose. So if I can resaw it successfully, I will net almost twice as many board feet. (I know that takes time, but to me time is not money, this is a hobby not a job)
I need some 3/8" and 1/4" boards for a jewelry box I plan to make.
Hopefully I will be using Walnut for this but am practicing with cheaper Oak.
