My horn bow build-a-long
DC:
Have you used a hair drier for heating bows. I just tested one and it has a setting that is very close to 50°c. Can't overheat it but may be drying? Seems like the way to go to me.

No I haven't so can't really comment. I use an electric hotplate. I got mine for very little money and it has served me very well. Remember it is the core you need to get hot enough to bend so slow and steady is best. It can take 20 mins heating with my set-up to get upto temperature. I also use electric heating pads wrapped around the limb.
Its best to do the corrections and let it sit for at least a few hours with the tillering stick in place and spread apart far enough to take into account any 'spring-back'.

Really? The core at this spot is only about 3mm thick and heating wood to 50°c(122°f) isn't warm enough to do anything. Am I missing something?
DC:
Adam says to take very little horn off when scraping. Is that just a general tillering statement or are these bows a lot more sensitive to horn removal than a selfbow is to wood removal?
bownarra:
The core gives the bow its shape. Simple :) If you don't get the core hot enough the shape won't change.
Common sense - go slowly :)
