Sandpaper


Gerald

Recommended Posts

For scraping a surface...I have usually just used a piece  of glass, with a freshly cut edge.    Have been known to cut a profile into the glass, to scrape  routed profiles.  

About any scrap piece of glass will do.   As long as the edge is freshly cut.    Sharpening?   Just cut and snap a new edge. Price?  Just go to your local Glass Shop, and ask about their scrap bins....usually you can haul a few pieces home...for free.  Beats waiting around for the next window to break ...BTDT.

For lathe work I sometime burn instead of sanding.

Just take a block of wood and push... It melts the wood away.

Price is going up and I watch the flea market for screws, stains,

varnish and sand paper... Sometimes you get great deals.

Question on scraping... Does the scrapers need sharping

every so often?

Sometime I'll burnish a turning, using the shavings. Run the lathe at high speed and hold a handful of shaving against the spinning wood. To me, it seems to produce a finish of somewhere between 500 and 1000 grit.

 

As for scrapers, yes, they do require sharpening. At least as often as gouges, to get a nice clean cut.

Scrapers need sharpening more than other turning tools . You form a burr as your cutting edge and that burr is gone almost as soon as you touch the wood . For much more on scrapers look up Reed Gray aka Robo Hippy on YouTube.

Whats the best way to get them sharp again?

I have an 8" grinder. I set the tool table at 90° and a hair below the wheel center. Turn the scraper so the "top" of the steel is resting on the table. Then free hand the shape. This setup grinds a slight bevel towards the "bottom" of the steel and causes the burr to be on the top.

 

Not sure if this is the correct method but it works for me.

There are two methods . Bevel up and bevel down. I tried bevel down at first but bevel up is just as good and faster to sharpen. I am not sure what angle I am using but I think it at 70 degrees. What Lew said But I use a steeper angle and at one time had different angles on different scrapers but after reading I decided the angle is not critical so use the same on both regular and neg rake. We can talk negative rake later.
