Let’s see, I had a couple scraps of Black Walnut sitting around the shop. Also had what was left from a Black Cherry floor joist ( From an old barn tear down) Both were being abused by every new-to-me handplane that came into the shop. Decided to try and make SOMETHING out of them, before they wound up as just a pile of shavings. Edges were planed square and ready for glue-ups. Didn’t have a way to make slimmer pieces, so I just used the scraps as is. Got a slab out of the clamps
Marked out lines to square the edges. Referenced off of one side. Didn’t like how I was clamping it to the bench, to use a circular saw, so, a sabresaw was used. Left some dippity-dos along the edges, so, a handplane to trim away the marks, and valleys
Ah yes, that dang pumkin. Well, I am using a JACK plane, right. Shop is in the cellar, along with all the stuff we store away. Old FranckenBailey #5 ( with a $3 Buck Brothers iron) did a decent job on end grain. There are some layout marks on the corners. Used ( or abused) that old sabresaw to cut the corners round, then a fine tune with a beltsander. A corded router ( WHAT!!!) was used to round over all the edges. A smooth plane to smooth things out. Took it upstairs and applied a coat of Mineral Oil to each side
Seems to have brought the grain out to where one can see it
So, how hard was it? Left the blank in the clamps for at least a day. Since the boards were not all the same size, or even the same thickness, had to handplane things smooth, and level. No tablesaw made things a bit different to do. Hardest part was all the time it took. Otherwise, not too bad, at all.
