A question of scraping?

Posts: 6 (07/02/09 4:17 PM) Reply Quote More My Recent Posts Message Me Connection Blocking Invite Ignore User's Posts	After some interesting lessons learned, I am back with a new and improved question around (semi)primitive bow making. Regarding the scraping of the belly of the bow to get a better overall tiller, is it best to scrape while the bow is strung up on the tiller tree or when the bow is unstrung and relaxed? I have been using cabinet scrapers with wonderful results, but do not know if there is a "right way" to scrape a bow for better tiller? As always, I welcome your wisdom and feedback. EV

Making changes to the bow on the tiller tree sounds a bit unsafe to me. However, I have heard of folks making adjustments with the bow braced, which assumes the bow has at least made it to brace height. These guys may guide you differently but that's my experience so far. And yes, your cabinet scraper or scraper of some type (I turn my draw knife around) is a very popular method for making small adjustments during the tillering process. Hope this helps.

But per definition you can only work on inner limb and mid limb that way. The string gets in the way of your tools when trying to work on the outer third. Make sure to excercise the bow after any wood removal. But this holds true for tillering in general anyway. "Sonuit contento nervus ab arcu." Ovid, Metamorphoses VI-286

If I need more bending near the fades I may leave it strung. I don't use a tillering stick as I believe them to be unsafe for a variety of reasons. I use a rope and pulley. I never leave the stave drawn when scraping. Jawge http://georgeandjoni.home.comcast.net/~georgeandjoni/ http://georgeandjoni.home.comcast.net/~georgeandjoni/

So far I have only scraped when the bow was strung, but not at any draw. I learned the hard way some time ago about making sure the bow is well exercised to bring the fibers into place. Ill post some pictures when I am done with this one. Thanks again for the feed back. EV
