Thread: Scraping.

Hi Derek,

That is a fair bit of scraping there. Did you have welders gloves on to stop your thumbs from burning?

The grain is looking great.

Cheers

Thanks Perry.

Thumbs are holding up

Makes my thumbs sore just looking at the expanse to be scraped, Derek! Jarrah seems to be one of those woods that responds very well to scraping. They should look very spiffy when done, and sitting in place.

I've done a couple of Jarrah kitchen counter tops, & was well please with the way they came up under a bit (lot!) of scraping. In fact the last time I did a really big area with card scrapers was on some kitchen counter tops (for a large kitchen, too!). After that, I decided life would be a lot better if I bought a LV scraper plane. I find I still have to use the cards to touch-up the really recalcitrant areas, but the plane has been a very welcome addition to the tool kit (or is that a non-addition, since it's part of a set? ).

I could never work out exactly why you get that slightly dull surface off scraper blades. I go to a deal of trouble refining my edges, down to the same grits as for final honing of chisels & plane blades, before turning the burr. Theoretically, they are as sharp as a plane, and certainly produce lovely fine shavings - so why does it look as if the surface fibres are slightly torn? I always meant to take a look at planed & scraped surfaces under a dissecting microscope, to see if that would answer the question, but never got around to it while I had the chance. One of these fine days......

Cheers,

Hi Ian

Different cutting angles. Scraping versus slicing. Type I (lower angle plane) versus Type 2 (scraper) cuts.

Hi Derek. I guess what I should have said is that I've never really grasped the full mechanics of so-called type 1 and type 2 cutting. When I read explanations, I came away feeling a bit like I did after reading some of my more turgid undergrad texts! A cut should be a cut, after all. However, my eyes & tactile senses accept there's a difference, so my logic just says that high-angle cutting (scraping) is not cutting, but something else......

Cheers,
