Probably not a big deal but I'm surprised, they're using it for support, but they didn't make the grain run diagonal ( bolts run with grain) by using a wider board they could have accomplish this. In my opinion
Very little. I am used to sanding everything. It was easy to hit it with 120 grit, then 220. Turned out nice and smooth.Really nice job Mike. I like seeing precision work like this. That router is really doing a fine job, smooth finish. Did you have to do much sanding?
