There is now and has been for many years a general consensus amoung many that if you scrape instead of cut, you aren't really a good turner. I have heard that for years, and certainly heard it from many a demonstrator when they say "what you need to do here is practice riding that bevel all the way to the outside", etc. They never pick up a scraper.
I learned to use a bowl gouge, and I like it. But when I have a deep vessel of sorts (like the one I just finished - 4" across, and 7" deep) I cannot get the angle to use a bowl gouge to finish the insdie bottom. Then comes the scraper. Sometimes the angles seem to keep me from getting the transition from bottom to side finished without ridges, then out comes the scraper. I have a 1/2" x 1" that is about
10" on the blade, and if I don't get too agressive it will leave a great surface.
But this has come to such a head that in one of the latest woodturning magazines they have an article by none other than Mike Darlow on the "cutting v. scraping" issue. He concedes that he seen nationally known turners (Sorin Berger?) make bowls with little more than a roughing gouge and a 2" scraper.
But he does in an off handed and nebulous way give up the fact that scraping could be an accepted way of woodturning. He makes it abundantly clear that he is a cutter, but allows there might be room for scraping.
Scraping is easier to learn, easier to control, and easier to teach. So why not use the scraper? I dunno. I have no idea. Even Darlow admits that he has had better luck teaching scraping rather than using the bowl gouge. Yet in his article, he seems (at least to me) to let on that he could accept scraping, yet not approve of it.
I say screw 'em. However you get the wood shaped the way you want is your business. Scrape, cut, grind, drill, or saw any way you want to get to the end is your business. Probably 99% of all turners are hobby guys anyway, so why not learn the easiest way to do something so you can get the most pleasure out of your hobby?
And I have never seen anyone set a pretty piece down because it was scraped, not cut. And strangely, most turners don't even seem to care.
