Craftsman 1" Round Nose Negative Rake Woodturning Bowl Scraper Wood Lathe Chisel

Description

Negative Rake Bowl Scraper -
Think of it as
a "Woodturners Cabinet Scraper"
I’m selling this 1” wide Craftsman HSS negative rake bowl scraper with a 2” side cut.
It’s a light to medium duty scraper approximately 1/4” thick and 1” wide.
This chisels cutting edge is profiled into a soft 1.75" radius on the left side to conform better to the interior of bowls. The
tight
right side radius is useful for some outboard work.  The bevels are ground to 40-degrees each side.
The cutting edge works best when the burr is used in the up position. It is the burr that cuts the cleanest, so keep a good burr on the tool when turning for best results. Sharpen the scraper with the small/short bevel down on the grinder platform.  When turning with the scraper, use with the large bevel in the up position with the small bevel down on the tool rest. The chisel is
in very good, condition.
Negative rake scrapers will cut the wood much cleaner than standard flat top scrapers, but will dull much faster. They are not a replacement for good tool geometry or cutting technique. They are
not
a bulk wood removal tool. They are not aggressive chisels. They’re a finesse tool used to clean up or touch up the interior of bowls or other turned projects by removing small amounts of wood. Good for removing micro lines, torn grain or making the final finishing or shaping cuts..
The scraper will cleanly cut very small amounts of wood leaving the surface ready for 180 to 220 grit sanding. They also work very well on plastics and acrylics cutting cleanly with a lot less chip-out. The scrapers also work very well on cross grain segmented
turnings
and stabilized materials. A turning project that consist of 100 or so cuts will use the negative rake scraper for the last 5 or 6 cuts.
These negative rake scrapers don’t tend to get catches, they are very user friendly chisels. I personally have half a dozen of these types of chisels in different profiles in my own tool collection. Negative rake scraping is a technique dad and I learned from Stuart Batty. I’m told that it’s a very old technique that was used in the production of Ivory billiard balls in England.
A note on sharpening:
I recommend you only sharpen the small micro bevel. Small bevels sharpen faster and that is the point of this suggestion. The micro bevel also allows the bottom of the scraper to have a wider foot print
on the tool rest
for better stability . The location of the cutting edge in the body of the tool steel doesn’t affect its performance.  I normally use a ceramic burnishing
tool
to produce a new burr after the tool is dulled. It saves the tool steel and produces a superior hard steel burr. This can be done several times before returning to the grinder to resharpen the chisel. Keep the wheels of your grinder dressed and clean. Dirty wheels will not raise a good burr.
Please asking any question you might have and thanks for looking.
A note on shipping times:
I use the USPS for all my shipping. I’ve been checking the tracking on the items I’ve shipped and the USPS is taking twice as long for items to be delivered. The longest delay was 17 days for a 3-day priority mail package. Most are 6 to 8 days to complete the delivery. This is largely due to the carriers not scanning the packages when they pick them up. No scan, no tracking, slow delivery times.
Please be patient with the USPS.
