Hi- I just received several 2-2.5” thick walnut slabs and maple slices. They are all wide, too wide for a planer. Any thoughts on how to turn them into 1” thick? I don’t have a bandsaw. Am I out of luck??
Looks like you got your hands on some great pieces of wood.
As you have probably gleaned from the other posters, there are many way to do this type of work. Of course, doing what I do, I would strongly second John Smith's recommendation of a "Frame Saw."
With your 4 pieces of wood you have two that will require a "ripping blade" and the rounds (aka "cookies" as some call them) will require a "cross-cut blade." Those are actually the easiest to cut either by a handsaw as Frank C rightfully suggested...or with a power tool like a chain saw which is a lot more dangerous if not use to them...and of course much more expensive to purchase.
On the point of making them thinner, that of course is an option. However, these appear to be very green pieces of wood. If you do slice them thinner, they are more prone to wrapping out of shape and/or splitting/checking, especially in the rounds. I can share that the thickness you have are about as thin as I go for cutting boards, yet the charcuterie trays are a more delicate item and would benefit from being thinner in most styles of them, but not all.
You can work with them green (of course) or wait for them to dry, but that all depends on your style of woodworking, skill sets and tooling methods.
There are some great posts here on the forum cover much of this. I can post links to them if you are interested or you can do a search yourself.
