Hey all, I need some feed back on bowl turning. Reguardless of how often I resharpen my scraper it is hard to eliminate end grain tearout. It seems I get a cleaner cut when I turn up the speed on my lathe. Has this been your experience?
How to you eliminate tearout, does a faster speed help or am I missing something.

A faster speed deffinately helps and like you said SHARP tools. Also try a little more angle on the skew. If it is too flat to the work piece you are useing it more as a scraper then a skew(knife) Don’t go too far but just ease into it with a VERY light touch.

Hope this helps.

generally, a gouge (properly used) will cut cleaner than a scraper, so you could try that or if you get an old file, grind off all the teeth, shape to a scraper and shapen it up really well, you could take a VERY light cut with minimal tool over hang. files are very brittle and are capable of hoolding a razor sharp edge, but because they are very brittle they can also shatter easily, so a light cut and little overhang are important.

I’ve also heard that if you put a little bit of wax on the tearout and take a light cut it can help as the wax supports the wood fibres. But I haven’t tried this.

what i do is rough out the whole thing then i sharpin my tools, turn the speed upto at least 2000rpm’s and make one last final cut with a freshly sharpened gouge and call it good, after that it’s time to start sanding. hope this helps have fun.
