1. Get better with a scraper.. ;-]
Try using a sweeping motion, like an arc...
A scraper cuts with the burr from sharpening it, and the burr goes away very
fast... Sharpen often..
Play with tool rest height and scraper angle.. I use about a 3 degree angle on
my scraper grind, so what works for me is to have the rest adjusted so that the
scraper when level is just a hair above center line.. Only practice will
determine what works for you..

Get a scraper rest or a rest with a flat top..
When you use the angled top rest that most lathes come with, the scraper is ok
when you're dead center, but as you sweep your arc, the scraper tends to tilt a
bit to the side when it follows the angled rest top..
My favorite is a big, ugly French curve rest with a flat top...

The tool you're looking for is sort of a single purpose tool.. I was thinking of
getting one for boxes and things, which IMO it's more suited for than bowls..

I tried this, which is ok for deep work and not bad for side/bottom scraping..

It would be a great tool if I didn't already have the Oneway Termite and if it
held angle better, but I fixed that..

It hollows well, scrapes some things well and is supposed to be an alternative
to a bowl gouge.. I really like the square shaft.. lets you know that your tip
orientation is ok..

Downside is the $120 price, but it's a pretty good tool..



Thanks, George, that was the brand I was thinking of. They have a more
rounded bit shaped like a "comma" that was what I referred to.

I'd like to think that I can fairly well do a smooth continuous cut with my
gouges. When it comes finishing time you can see or feel imperfections that
a larger contact area avoids. I'm after that waxed feel that is to the hand
what a heavily lacquered cherry apple paint job on a car is to the eye.

You answered the Oland Tool post with a shear cut remark.

I'm anal about a smooth, flowing finish but a find the scraper is not
that easy to just slide through a continuous cut. This could be my
inexperience trying to use that way. Further, since it's flat, I find it
awkward to bring up enough for a shear cut.

So, I'm thinking of a way too expensive tool at Klingspor's that has a
removable curving plus flat cutter attached to a stout round bar that has
some 1/4" flat on it. Seems this could be maneuvered a lot easier.

Your thoughts? Or anybody else's?


I'd rather cut. Forged gouge, half inch size, rim to button is pretty
easy to do, given the amount of bevel available to keep on the work.

If you're shear scraper struck, this works.

can "Hunter" it with carbide tooling or use other shapes.
