I am building a plant stand with mortise and tenon joinery out of hickory. The tenons are 1.5 long, .5 deep and .28 thick. I made them a little too thick and need to reduce the thickness. The mortise is .23 wide in spite of the .25 mortising bit.
I have a belt/disk sander but it isn’t very precise and can’t get close enough. I am using an oscillating tool with a triangular sander that is kind of iffy and noisy. Looking for some guidance here. Hoping there is a better way. Thanks.
