This is the one (Thanks Mike! :eusa_wall) I was attempting to use a skew to smooth the outside of the bowl and it caught, kicked back, and then I managed to run the freshly sharpened skew back into my hand. A word to the wise...DON'T DO THAT! It hurts!:lol: Thankfully nothing serious!

Thanks Dave!
That was courtesy of the Airedale. He didn't want me to have that ball! You should see the finger!

You should see the 5 stiches in my palm that one of my skews gave me as I was putting it away :eusa_doh::eusa_doh::eusa_doh: Don't stop turning the tools will revolt :lol::lol::lol:
BTW, I think that skews are really only good for spindle work. A nice fingernail grind gouge would be better for that final smoothing cut, you use the wings just like you would a skew to slice the wood.

Ok, keep your hand out of the dogs mouth...I am assuming that Airedale is a dog...right? :eusa_thin:eusa_thin
:lol::lol::lol:
Dave
Lookin' good, man. I like the spalted look ... adds a lot of character.

Nope, just the nut operating the machine!:lol:
As with most shop accidents this was likely from using the wrong tool. It seems to me that most shop accidents are operator induced. Either using the wrong tool or using the tool improperly. Accidents happen, but I'll bet very few are due to the tool being dangerous!

Perrty wood in that bowl, looks like it was good and ripe.
Thanks

I'll echo DaveO on the skew usage. If lathe chisels were golf clubs, then the skew would be a two-iron to me. Every time I use it I mess up the bowl. Before I start spouting information, this is a really nice bowl you've done and the shape is quite pleasant.
That tearout looks to be on both sides of the bowl, which means you are hitting the end-grain and it is just pulling loose becuase the wood is so soft. Sanding will help that some, but only at the very end. A guy showed me a couple ways to mitigate the problem.
You can use a very sharp bowl gouge angled upward into the inside of the bowl. Rest the not-so sharp bevel of the gouge against the inside and then slowly turn the gouge until you get very fine shavings. This in effect cuts the wood fibers rather than tearing at them. I've found that an Elsworth grind is best for this, but not necessary.
Also had some success with a round nose scrape angled downward and taking very shallow cuts. I took an old cheapo Harbor Freight Flat Chisel and turned it into a bowl-scrap by making a sweeping half circle grind on just one side of it. You can then grind the top of the bevel too to make what is called a Negative Bevel grind.
Here is the Bowl Scraper:
And an example of a negative Grind,,
to me the grind on this one is way overdone though:

Nice bowl!
A good way to handle tear out, sharpen your gouge, and take some very light cuts. Slow lathe speed if you have too!
Using a scrapper, not always a good choice for dealing with tear out.
If all else fails, I grind wood shavings in an old coffee grinder, squirt some CA glue on tear out and apply saw dust before initial sanding. Press saw dust with paper towel. Blow, or wipe off excess saw dust. May have to repeat procedure couple times. When through sanding, wouldn’t know had any tear out. Even after applying finish, you wouldn’t know unless told you. Now have a jar full of various wood shavings ground up ready to go! May take me awhile to find that coffee grinder.
Oh, word of caution, don't borrow or steal wife's coffee grinder!
