Hi, I have been turning black walnut lately and have been having a terrible time with tear out.Its seems that walnut is prone to tear out is this true. remembering back I can’t think of a species of wood that I have turned that has had that much tear out and its deep. Any suggestions thanks mike

Hi Mike

Shallower cuts, and sharper tools. Walnut like a lot of woods can have a fairly open grain, and it if you go deep, especially with a tool in need of sharpening like a lot of woods, you’ll be seeing some chunks. Get after those, and they quickly become ragged chunks.

Know you don’t like watching videos but this DVD to have and review worth your attention. If can find Bowl Turning With Del Stubbs DVD normally less than $20 in your area buy it. Was my first VCR tape on woodturning ever bought.
Here is a short sample: https://www.youtube.com/watch?v=kbijBCos62E

This guy makes everything about bowl turning so easy to understand! Yes it is old but nothing really changed about turning bowls.

Little backgtound on the guy:

Other than already mentioned maybe the same as punky wood.
Turn close to the shape then start coating with a sanding sealer to harden the wood. I use 1 part shellac to 2 parts DNA. Dries fairly quickly. You will probably need to add new sealer at least every 1/8 -1/4” removed.

Thanks for the del Stubbs links I’ll see what I can find, any suggestion where I might find his videos. Any on utube.. Lee the wood isn’t punky this happens with all the walnut I have turned from several different trees. Other wood i get tear out but not as bad that why I thought it might be a quirk of the wood

I don’t turn much but when I do the shavings just fly off. Bevel always in contact with the wood.

Do you have shavings or dust? What does the surface look like? Poor?

I have a little of both, I think I am getting better at sharpening, maybe things cut better sometimes but I still get a lot of tear out

I’d guess the problem is that the tools aren’t sharp enough. After all these years of turning this and that, I can tell when it’s time to walk to the bench grinder. There’s a Veritas tool rest on it, which is infinitely variable on angles of sharpening. I can sharpen a dull gouge in 30 seconds. Takes longer to find the angle on a scraper.

Have your say...
