I just finished up a step stool for my brother and sister in law. The top two steps are from a piece of lumber I got from my grandfather earlier this year when he had to close down his shop. I don't think it was a fresh piece and probably sitting around for a number of years due to his decline and inability to do as many projects as he wanted. At first I thought it Brazilian Cherry (Jatoba) and I wanted to use it because my sister in law is from Brazil, but after putting the finish on I realize it's a lot more red than I thought. Now I'm wondering if this could be Bubinga or Padauk. I took a picture of the underside of the stool where you can see some sap wood that is a dull yellow color. It's fairly open grained, very dense and heavy and oily. I put four coats of General Finishes Arm-R-Seal on, which is a wiping varnish that does contain BLO, but no stain or dye. Any thoughts?
