Dear Bob; I too am an ammateur maker although if you manage to flog a set which
I have in the past then I suppose it makes me a semi pro maker. You seem to
have been more successful that I have in gaining a response to a request for
information as past blogs indicate from the sublime to the ridiculous in reply.
Tone holes seem to be something which irritate every maker when asked to supply
their own tweaked measurements after many years of manufacture. The low notes
are the most difficult to obtain ie below lowest D where the harmonics are
spread farther leaving a large variable between each note. A tweak can result
in a shift of 12mm over 25c and leave you with a soddin' great hole to fill and
all that after 200 houres work. After my request and you can look at the
archive, I recieved 3 replies out of a what did you say membership and one of
them was to ask how to measure the bore and he never replied either bless him.
If you are realy serious about this subject then sharing of information is
vital and all of it not just the obvious. Nelson's site reqired Auto CAD to
read it Frances bailed me out on that one and even then after building a
chanter (long) I found at least 20% of the measyurements out by as much as
12mm. Been there done that too and now into year 7. I make my own drills from a
2.5mm welding rod. Malcolm-- Bob Salter wrote :
Thank you for your replies.
Francis:
I had considered your method making some kind of hardwood vice
from something incredibly hard like bubinga and mounting it like a
toolpost on the crosslide. Is your jig along those lines or something
more grand in metal.?
Richard:-
I have long considered using a dremel in this way. However I lack the
invention gene ( I can copy anything but not invent). I never could
figure out how to secure my dremel so it didnt move. Could you throw a
little light please.
I hesitate to ask but would there be any interest in a dedicated nsp
forum where one could search topics for old answers and things would be
permanently recorded for all? I have one good to go, just waiting for
members. However I dont wish to offend anyone or alienate anyone by
doing so. If you are interested, please let me know and Ill send you
the url.
Thank you for the help
Bob
