'Hand' Scrapers before Sanding...
Dec 9th, 2015 at 12:22pm
 
I read an interesting post yesterday over at SawMill Creek where another turner showed some extremely nicely done pieces with a glass smooth finish.  The turner extolled the virtues of using traditional hand-held wood scrapers as his final process before switching to sandpaper.  Question...have any of you worked with hand scrapers during the final turning phase?  It sounds like an intriguing method to get a smoother finish...just curious.

Yes.  I use the curved ones on some hollow forms and sometimes a bowl to fix any tear out I can't get out with other tools.  Works better then low grit sand paper as you don't have deep scratches.  A fresh burr on the scraper is a must of course.  I don't use when the lathe is on however.  Some other turners do but I am a nervous Nellie when it comes to sharp edges and my hand inside a bowl.  I suppose you could at very low speed and the outside of a form.

About a year ago Brad Adams ( a local Bay Area turner ) gave our club a demo and used very thin scrapers to take out tear out and tool ridges. Since then, I have been using them with great success on the outside of my hollow forms and platters. Can't find curved scrapers for inside of bowls that are thin enough. I do use the scrapers with the lathe running and get whisper thin shavings. Here is a link to the scrapers.

I have a set of three Henry Taylor "fine finishing scrapers" that work great for those hard to clean up tear out areas. They are not for heavy cuts, but the round rod makes tool presentation confidence very easy to achieve. A bit pricey but they do what they are designed for. I don't use them often but am glad to have them when the need arises. High lathe speed and very light stroking cuts with a freshly sharpened scraper works wonders pre-sanding

To each his own, but these tools are not a power tool accessory, they are a hand tool.

Hand tools for sure, and difficult to control with the lathe spinning. You can make your own if you have an old hand saw, and cut and grind to your favorite shapes, and then burnish the burr. If there is really bad tear out, they might be handy, but I have not found any advantages over a good burr on a scraper. I do like them for flat work prior to sanding, or for removing scratch marks from the drum sander...

I was watching some Japanese turning vids and they used a hand scraper with great results.  I would love to find more technique info.


P.S.  My 8th post in 8 years of being registered here.   Cheesy

Hey Randy, at the risk of sending your post count into double digits, I think many of us would like to learn more about that process. Japanese tools and usage often varies greatly from western methods.

I can see them being useful on end grain turnings. If I could see the Japanese turner using them, I would suspect that is how they are beint used. For me though, not on flat grain with the lathe running. Just haven't found them useful.

The Tracy Owens tools from Henry Taylor are interesting, and scrapers from half round stock make shear scraping easier. I to round over the edges of all of my scrapers for that purpose. I did see Tracy demo them in San Jose when the Symposium was there. For me, another 'I all ready have tools that will do that' situation.

As I mentioned in an earlier post,'to each his own"

There are literally hundreds of "scraping" type tools specifically dedicated and designed for woodturning.
I do not understand why anyone would need/want to opt for a cabinet scraper or card scraper, a tool that isn't designed for anything other than flat surfaces. I am aware that there are styles with profiles other than straight, these are still for straight ( linear ) scraping, (coves & flutes for example) not round objects.

Curved scrapers are fantastic on the inside of warped bowls. Don't use a tool rest of course. Wear gloves. They can take away tool marks like nothing else. If your burr technique is good... you can get angel hair shavings and save a great deal of sanding. My skill has improved to the point of not needing to use them too much, but for bowls turned long ago... they work well!

I will sometimes use a curved one to clean up some end-grain tear out inside a bowl that's being stubborn....or a patch that seems to sand all around, but not that spot specifically...   lets me skip the 80 & 100 grits and go to 120 and higher more quickly....   haven't dared to try it with the lathe actually spinning however.....

I also use it on the bottom of a larger bowl to get the last of the bottom tenon leveled out and smoothed before finish sanding....

Around 40 seconds in shows a curved blade scraper with a red handle.  I would love to find more Japanese turning vids.

Randy...Absolutely hysterical but if you go look at the videos section you'll find the exact same video I posted here a couple of days ago.  I found it after reading your initial post, got curious, and began hunting around YouTube for japanese turning videos.  Great minds and all that....Cheers, John
