That's a bit odd. You should usually get MORE response when you scrape the heart and make the blend. Which maybe means the tip you that you initially get isn't quite the tip you should be getting. Is your reed very closed after scraping the heart and blend? If you've barely touched the heart and tip and the opening is already "perfect", it's going to close up too much.
Everyone has their own method. This is usually mine:
1) Scrape the corners of the tip, diagonal and also straight, to thin it out a lot. This prevents me from catching the knife when I do step 2.
2) Start scraping along the whole length of the reed in (the amount of swipes depends on how much cane you take off each swipe... I do about 10 each quadrant). This creates my windows (and the shape of the bottom half of the windows). Avoid the rails.
3) Mark off where my tip begins and where the windows should end.
4a/b) I vary on the order of this.
a) Scrape the tip with diagonal angle. Roughly define the tip starting at the pencil mark and scrape enough so that the tip can be opened without cracking the reed. Thin down the top of the tip a lot.
b) Scrape on the upper half of the reed, knife straight to remove cane from the future heart/blend.
5) Cut the tip to reasonable length (2 mm or so of desired final length). Insert plaque.
6a/b)
a) Define the windows more, scraping up to the pencil mark noted earlier. Upper part of windows now defined.
b) Define more of tip, making sure that the tip starts where I marked. Get it to near the final thickness.
7) Scrape in the blend and thin the sides of the heart, making sure there are no bumps in the blend. Generally a lot of the rail comes off.
8) It is only at this point do I usually bother to crow the reed.
9) Now this is the point where I do all my tweaking. This can involve scraping on any part of the reed for major/minor adjustments.
The tough part is learning how to get to step (9). It is way too easy to do final tweaking before the reed is ready to receive final tweaking. You can make your tip perfect but if the rest of the reed hasn't been scraped enough, it will be all for nought.
I generally keep a straight knife if doing the blend itself. I continually define the start of my tip, though, which I suppose is also blend work, with the knife at an angle ^. I even angle the knife as a V if needed to get rid of bumps.
