I have been fortunate; McMaster-Carr carries the odd size of brass tubing at 1-3/8 inches (this size is used on the overflow drains on old claw-foot tubs; perhaps that's why it is still available), and only $15.20 (plus S&H) for a one-foot length. I stuffed and re-drilled the stock holes at a correct angle, about 2 to 3 degrees and added the ferrule this morning (the brass tube came this am).
Here are all the parts:
from back to front: Drones in common-stock. Chanter stock and chanter. Blow-pipe stocks and blow-pipe. Bellows inlet bushing and outlet tube, bellows cheeks.
The bellows-cheeks are drilled, but a 1/8 inch square groove must now be cut along the stitching holes to provide room for the stitching to lie below the surface. The blow-pipe and bellows-inlet both have flats cut on their valve-ends; a banjo-shaped leather flap (the bellows flapper valve) will have its tail tied on the flat with waxed shoemaker's thread, the tie also providing the seal in the hole.
BTW, I made the cheeks from old 3/8 oak drawer sides (not turning, but I thought you'd like to see the source material):
It's going to take a good long while now to make a bag, leather the bellows, and make the reeds; the overall project will probably take at least a month or so now to finish those last tasks.
I'll try to post some MP3's of pipe-music when I actually get them working.
