white wenge, = Amphimas pterocarpoides, more commonly called lati and it is on my site with that name.
BUT ... based on the end grain, I think what you are showing is panga panga (a close wenge relative) sapwood
Later: I looked at Eric's pics and was surprized to find that lati has the same end grain as wenge and panga panga. I was sure I remembered that it had a different structure but I check the North Carolina State University micropics (since I don't have a sample myself) and sure enough, it's the same, so I guess what you have IS lati.
I prefer Fusion 360 for almost anything woodworking related. I only use sketchup when I need a cut list when using sheet goods.
Fusion is far more powerful and user friendly once you get the hang of it.
I was where you were a couple of years ago. I got comfortable with my table saw by making a bunch of shop cabinets, mitre saw table and a hefty workbench/outfeed table (made out of 2x4s and a maple top from Ikea). The point was that I just started cutting stuff, getting familiar with the saw and how it reacted. I also spent a bunch of time looking at youtube videos on table saw safety, kickback, etc. I use some easy shop made push sticks and am always very wary. Just go for it, safely...
It was only after I had made a bunch of shop furniture that I bought my first bit of hardwood and started messing with that.
