i think the ridges inside my deep bowls are from the chisel flexing while cutting , tryed to take smaller passes ,but that takes to long , so my next one i might make a thicker chisel , ( having a mate with a mill makes it easy ) looking around for some 25mm HSS dowel :~ might have to bye a length:~

i also tryed not sticking the chisel in straight , but paring toward the middle of the bowl bit by bit as you go deeper ,that seamed to help ,but still ended up rough as guts , im a newbie at turning so take this as gossball

Light cuts is normally the go, I use a scraper and try to knock the tops off the ridges, then take one complete pass

how do you use a scraper when it larger the the radius of your box though?

I take it your talking about where the bottom meets the side.

I have a few scrapers with different ground shapes on them, you might need to regrind one of your scrapers or buy another one :sneek: if you can get pass hubby :~ .

I normally use one just for the bottom and one for doing the the small radius and the sides

Another trick is to use a BIG old screwdriver that has seen better days. Cut the end off, then grind one side flat for about an inch. Thinking of that flat as the "top" of a scraper, sharpen the end with a nicely rounded profile.

I'm pretty sure I've posted pix of it before... [rummage, rummage] Yep... here's the Side (http://www.woodworkforums.com/attachment.php?attachmentid=26478&d=1152948925) & Top (http://www.woodworkforums.com/attachment.php?attachmentid=26477&d=1152948925) views of the cutting edge.

This is my "fits all round corners tool." :) If the curve of the scraper is too big to fit in the corner, I just roll it on it's side until it fits. Because it's just a screwdriver it's not the best steel in the world and needs fairly regular sharpening. But it's just soooo bloody convenient that it's worth the hassle. ;)

What a great idea Skew. I'll haff to git me one o' dem! :) Sorry too much time with the kid over the past few days.

Toni, I tend to agree with djstimber I normally get the item close take any lumps off with a scraper and then one or two really light cuts to get that nice smooooth finish. Works for me anyway:cool:
See ya

Hi Toni,
Smaller cuts and smoother cuts ie take it a bit slower. Then use the scraper to finalize the shape and smooth the whole deal out. But scrape at 45' or so [shear scraping] to the wood. Not with the scraper flat on the tool rest.

I have a couple of scrapers [home made] with varying radii. Ideally the scraper should be a bit smaller on the radius than the bowl being turned.
