100# self ash, complete with whopping chrysals....!
WillS:
So my first attempt at doing a bloom was... Reasonably unsuccessful, shall we say. Lots learned however, which was the secondary goal!
Here's the bloom fitted.
The result was a complete failure, the bow exploded right in that area.
Lesson learned - making a very small patch in a weak area doesn't work, as the bow moves too much around it, and there's not enough solid wood to take that stress. Essentially I removed the chrysal, but created two more in its place.
I did get recommended by Jeremy to use a 12" long bloom, but by then I'd already glued the thing down!
Del the cat:
IMO patches need to be long and gently curved, same way as you would blend in any other feature.

WillS:
Yep, definitely agree! The smaller and more abrupt things are, the more stress they take.
Trouble I have is that I've never had any sort of power tool - just a few rasps and drawknives. This makes long sweeping smooth curves very difficult to create, whereas with a belt sander or disc sander you could achieve that in seconds.

Yeah, I dithered for ages about should I get a cheapo belt sander (about £75)... eventually did.
It wasn't great, but with a bit of fettling and a good coarse belt (40 grit) it has been V useful.

Marc St Louis:
I don't recall Jaroslav's Ash Bow but you all have to remember that it's not density that matters when making any bow, it's how elastic the wood is. I wouldn't bother making a warbow out of any Ash we have around here regardless of how dense it was because it's just not elastic enough. If it was all I had to work with I would definitely make the bow long. Heat-treating does not improve a wood's elasticity
