Topic tags/keywords: question walnut sander router sanding

I just flattened my board, and I ran into a problem. I am having tear out on the walnut parts.

I don’t think the router did this. I used a dish cutting bit from MLCS that stated the bottom was flat. Not exactly. I ended up with a scalloped, or fluted finish. The first side I used my ROS with 80 grit on it to even it out so I could flip it and flatten the other side. Once that side was done, I used a belt sander with 60 grit briefly, then went with the ROS. I think the belt sander did the tear out. The router bit is not a problem any longer, as I won’t use it again.

Has anyone had this happen to them? I haven’t worked with walnut end grain before, and the walnut is the only wood affected. Is there a food safe filler I could use? I can reflatten, but I’d rather not. This is the first one I’ve done, and will be sitting on my counter, whereas I’d like to figure this out before I make one for another niece’s wedding.

It’s a little bit difficult to see in any great detail, but it doesn’t look like tearout on my monitor. It looks like checking.
A closer, more detailed picture would help.

I use a belt sander on mine exclusively for the first part of sanding. After starting with what I consider a very flat glue up, usually made from hard maple, walnut and purple heart, I start with 32g, then 60g, 80g, and 120g. After those first four grits, I move to the ROS and progress on through 240 grit then finish. I’ve made less than a dozen boards this way, but never had any kind of tear out or anything that resembles what you’re experiencing.

Wow. What a nice tight glue up. Sucks with the problem you are having.

It looks to me like the belt sander had some aggressive grit in it since the grooves are all the same direction regardless of the walnut orientation. I guess you got some more sanding to do.

Sorry, Tony S., I didn’t get home last night until well after dark and the desk lamps I use in my cave don’t lend themselves too well for photography.

Thanks again for all your help, but I think the direction I’m going to head in is taking it down a little further. Does anyone have recomendations for the type of router bit I should use? MLCS has a 3/4” bottom cleaning bit that looks like my answer.

Steve, thanks for your pity, after all this is all your fault ;) I wouldn’t have it any other way, and I know I’ll get it, it will just be thinner. I’m off to work my way into the new year, and I’d like to say to you all- May the New Year live up to the hopes and wishes we all have for it. Have fun and be safe.
