Wow! Lot of good feedback guys. Thanks very much.
Where to start. All in all I think probably the Bracker isn’t the whistle for me especially if its air requirements are more than a Burke. Unfortunately, Peter, I can’t draw any help from your comparisons. I’ve never played a V3 and Overtons are so varied. Though since Hans is only 3 hrs away I would still like to visit his workshop sometime. And I find also the tone of the Bracker, like that of the Burke, to be a little pure for my liking.
If I were to try to make a low D for you I would start with a narrower bore than would be typical for a low D. It would, as a result, be quieter overall. The air requirements would be less overall. The low end might be a little sketchy however as stable as possible given the bore. But the high end would be easier to reach and hold.
Big holes or holes with very well finished walls help the high notes speak too.
A movement of the plug of a half millimeter forward or back can have a similar result.
Some great thoughts here Feadoggie. The third one is beyond my understanding but I would be curious to understand the second one better if you have the time to explain. Getting technical for a while and going back to Colin Goldie’s whistles, obviously each individual maker has limits to the parameters he can change. By virtue of the design of the Bracker, Hans can’t change the windway height for example. Colin prefers to work on windway height and he has a spent a lot of time trying to make the head air efficient. My Low D with a height of 1.00mm is at the softness limit for maintaining that efficiency and he is reluctant to make a 1.1 or 1.2mm Low D because of the air it would use. Unfortunately there is no way of quantifying how much it would use, or whether the increase would be enough to get the top end I want. I just bought (or tested) a Low F from him, a 1.1mm (1.2mm being the Low F’s limit) partly because I’ve wanted to try a Low F anyway, partly to see if the narrower bore would make the top end easier to get. I’m confused because though it has a narrower bore and a higher windway, it is a harder blower and the second A & B are more difficult to get than on my Low D.
The Low F is going back which is a shame. I loved it apart from that. Going back to your thoughts and quotes, I wonder if I should discuss with Colin the possibilities of a narrow bore Low D and also shortening the window. I love Colin’s whistles and their drainpipe tone . . . . which makes me wonder what making a narrow bore Low D would do to the tone.
Thanks stanton135 by the way for your quote which I’m well familiar with. I’ve often referred to those design parameters of Guido’s. I did try one of his high whistles but found great problems with the fipple, my lips getting in the way of the windway, plus I much prefer the tone of an aluminium whistle. So I don’t want to buy another of his otherwise excellent whistles. DIY is not a strong point for me either. How are your whistles coming on, Feadoggie?
Which leads me on to the last two points advocating the Lambe & Reviol. I’m not absolutely sure that the mystery whistle I had was an early Lambe. But what you say, ecohawk, confirms what I’ve heard elsewhere, that the bell tone is very sensitive. I tried a Reviol and it was great as far as the second octave was concerned, the bell note wasn’t overly sensitive and air requirements were very manageable (does it have a narrower bore than say a Goldie?), an amazing combination. My difficult was two-fold. Clogging for which the toothpaste treatment wasn’t ideal with the coating. And I struggled to seal the holes properly and wondered about the coating again. But looking back I regret not giving it more time and wonder if I would get used to it given a little patience. Big Whistle may be getting them in again soon. I wonder . . .
Finally Marc Lofgren has suggested he can shorten the window to make a Low D (or maybe Low F) favouring the upper octave which is perhaps another possibility.
Thanks for your helpful thoughts. I’m very conscious of the limited funds I have available and don’t wish to lose money experimenting to find the right whistle so making a decision isn’t easy. But you have given me helpful ideas especially with regard to the possibility of a narrower bore Low D (the Reviol does look a little narrower than the norm!)
