That size and thickness of wood is very difficult to find. If you do find it the cost will be much greater if it has been dried. That is because it takes a lot longer to dry thicker material.
If you are going to do a lot of this sort of thing I would recommend a drum sander rather than a planer. I got rid of my planer at least 5 years ago in favor of the drum sander. All of the sages say that a woodworker must have a tablesaw, jointer and planer. For doing this stuff I find a tablesaw and a drum sander much more useful. A band saw helps for really thick stuff. Anyway, what have I got against a planer?
2. Nicked blades which are not cheap to replace
3. The inability to thickness shorter stock, I can easily run a 6 inch long piece through the sander.
4. Tearout in figured wood
Yup, if I had to thickness a lot of board feet and time was a consideration a planer is the way to go.
I have done quite a few thick models, up to a little over 3 inches in thickness. I also like to work with pine. So after cutting big box 2X material to length I flatten one side on the CNC (that is why I also sold the jointer quite a few years ago) using a large bit 1.5 inches diameter with a 75% step over. I then flip it over and flatten the other side. Pass both sides through the drum sander after that. That all goes surprisingly quickly. I typically flatten in the CNC at 350 IPM, each side usually takes under a minute. I built a pair of vises for the CNC that make holding the pieces extremely easy and fast.
Working with a cnc on a regular basis requires figuring out what is going to work best for what you want to do. When I first started I did like most folks, put a piece of material on the machine, do the interior details then cut the piece out. That meant I always had to use material that was larger than the project. Having done a lot of woodworking I knew that cutting pieces to size on a table saw is much MUCH faster. Cutting them to length is much quicker on a radial arm saw. The problem was accuracy. Now my table saw has a digital readout and so does the RAS.
The vises are extremely useful, especially for smaller pieces, and really useful if the parts I am making require work on more than one side.
So, I guess the idea is that it pays to do some tooling up if you are going to do a lot of cnc work.
BTW, cutting stuff into strips and gluing them up as you wrote about solves a lot of issues, but it does not always result in the best looking project. Sometimes using a gel stain helps with that.
The next time I do a thick project I will document the process that I use and post it up here. There are bits and pieces of how I do things scattered throughout my posts but it might be nice to have that information all in one place.
