Default Poly VS ABW stocks

Hey all,

So I have a cracked tenor stock that Iíve let sit and dry out, and it seems to have sealed itself back up...

Iíve whipped the outside combing with black hemp, air tested it, and oiled it.

My question is: is there a harmonics/tone difference based on the material of the stock?

There is not.

(I have also done this on each set of pipes that I've had)

For material property comparisons (such as wood vs polypenco) as it relates to highland pipes take a read through David Locky's website.

More and more as an engineer I realize so many aspects of A/B comparisons are emotional ones and not ones based on actual results where you don't know the difference. David does a really good job to tie the science and the emotional sides together.

Itís less a sentimental question and more an aesthetics one for me. If there was a difference in tone Iíd switch them back immediately.

Looks wise theres the nickel vs Imitation Ivory clash but it doesnít really bother me

Greetings, DamhCabrachPiping & William,

Hmm... not intending to horn in... but... I am
most probably much more of an Old School
Traditionalist (living in a cave, as I do :) than
*into which... you shall probably ever bump!*...
and especially when it comes to... kit & gear...
which also includes the instruments. (Well,
what else is there?... save the drill? :)

*(Ah, nothing like a Churchillian phrase to help
bugger up the afternoon's bit o' chat. :)*

My two oldest sets, 1908 and 1916, now are both
and always played.... with a 20-year old Delrin
blow pipe... which has some sort of marvelous
modern contraption in it... which obviates any
need of Little Macs or flapper valves.

It is turned in such a fashion... that any of those
optical differences... between the blowpipe and
the drones... are negligible enough... so that as
my much-sainted GrandMama would say...

"You couldn't tell the difference from a galloping horse." :)

I am not a wet blower... but even if I were... the breath
fumes from the Guinness... and the Tullamore Dew...
would prove more than enough... to easily "corral" any
moisture in my breath. :)

Still and all... might as well try to help save these two
very old blowpipes... and keep them oiled and on the
shelf... except for the times of formal playing... and
presentation.

I trouble you with all of this above delineation... as
I feel that you may... place and play... these poly
stocks... saving your originals... and without any
concern (at all) of your doing anything that would
bring your pipes and your playing... "out of harmony"...
with our most.. wondrous Past...

After all... most of us who wear spats... do have velcro... :)

And as a further aside... and at least in my case...
though I have wondered... time to time... if my air...
through a Delrin blowpipe... might be a bit different...
than the air delivered through Blackwood or Cocus...
I simply thought that the Guinness and the Tullamore...
would take more than adequate care... of that! :)

Enjoy your trouble-free poly stocks... and have a grand
time of it! :)

Regards, and happy playing!,

Pip01

Well, looks-wise, there's usually still a fairly noticeable difference with mixing blackwood and poly. It'll depend on the wood, available light, etc ... but of course, for many would-be listeners, they wouldn't know.

The set I play at rowdy stage gigs is backwards from what you're doing ... poly pipes, blackwood stocks ... simply because I didn't feel like tying in the plastic stocks into a new bag. When the current bag for that set wears out, I'll finally swap in the plastic stocks.

Below are a couple images where the light shows the different color of the stocks with that set. The stocks have a chocolately-brown hue, whereas the pipes are straight black.

Cheers,
~Nate

DCP, I'm confused. You're saying you know there isn't a difference between the tones and it's just a looks thing to you.. but your thread post was explicitly asking for the tonal difference between materials?

You bet, thanks. And yes, itís a Campbell. Nifty thing, though Iíve found itís really only for fine-tuning. Works for us, in that I tend to go sharper than the other piper as we play, particularly since we dont usually have the license to do a good warm up before sets (other acts to consider, etc).

Anyway, as to the original poster, I think you may have misread a statement or two of his .:: my understanding is that:

- Heís asking if they are tonal differnences in using poly vs wood stocks

- And (if someone were to have stated that there would be a difference) ... he would then reconsider the switch

My read is that the second statement was implied ... though in reading it, I think its easy to miss that.

My 2cents anyway

Cheers,
~Nate

I have the original ABW stocks on my 1979 G&Ms, although thwey're on the fifth bag in 40 years. I have a synthetic bag with poly stocks for back-up and play on that set-up periodically so I know it's reliable. Before tying in the synthetic bag, I had the poly stocks in a spare Gannaway bag. I cannot discern any difference in tone on my drones between the two sets of stocks.

Dave Atherton, who makes some of the finest pipes available today usually does them with a poly blowstick stock, but of course that is not the same thing as a drone stock re tone. But the poly stock does not stand out in contrast to the drone stocks.
