They are all nicely finished, and your stem work is looking good. You'll be selling those without much trouble if you keep your prices reasonable.
Critique: First pipe - briar band(?) on stem doesn't match coloring of briar on pipe. The effect of this band on this pipe is that you actually see 2 bands of wood separated by 1 band of black, because of the smooth ring on the stummel. So it doesn't look quite done! Because of the blast, the shank is a little skinnier than if it was a smooth - balance this out by tapering the stem just a little more quickly - it looks a little too fat for a little too long because of the dis-balance against the shank.
But the shape is nice, the stem bent beautifully.
#2. Pretty good billy. Classic billy needs: bowl height from top of shank = shank length, bowl canted forward just a little more so it doesn't look like it's leaning to the stem (or the stem looks like it's peeling up toward the bowl). This is a brandy-ish billiard - move the fattest part of the pipe up to the middle, or closer to (take of more material at the bottom). Top of the bowl is really nicely cut. Sharpen up the lines of the stem - it's rounded over near the metal rather than flat/tapered in a straight line.
3. Good brandy, great grain. It's a little heavy - when you start a brandy with 1/4" of material at the top, it's gonna flare out and be real heavy looking. Flare slightly less or start with a thinner top and it'll lighten up. The heaviness carries through to the shank, because the bowl and shank intersect quite high, and this leaves the thing feeling a little pudgy and shapeless. 2 remedies - thin out the bowl walls a bit and more importantly, move the shank "back". Instead of aiming the shank right at the bottom of the chamber, build the pipe so the shank angle would miss the bowl, stretch the pipe out a bit, and you'll be able to define all this stuff. In keeping with that, you would also be able to make the "lowest" point of the pipe just back of bowl center, and this looks really nice on steep bents.
"What the hell are you talking about Sas?" Have a look at this old Ceppo - it still has a huge, masculine presence, but the curve of the shank is graceful and the stretched out build really let Georgio define the bowl shape. I'm not saying this is the only way to build a bent brandy, but imho this one contains a bunch of design ideas that are clear to see and well executed. The rim on this pipe is about 1/8" thick around a bowl that is pushing toward an inch across.
4. The dublin is beautiful - I'm not sure what I'm seeing but from one side it looks as though the stem is high-centered in the shank, and from the other side not so... what shape is that shank?
Anyway that's a damn fine looking pipe from a really nice cut of wood. Personally I think the chamber hole presents as a little small, but I understand that you are showing off the rim (and why not! who would cut a hole in such a piece!!) I think it works with the overall heaviness of the pipe.
Don't be shy about copying a pipe you like - there's no better way to learn about how pipes go together and why certain things look right or wrong depending on the application than by actually trying to physically reproduce a pipe.
Anyhow nice job on all these.
But, I would still like to get it in the hands of one of the forum members and get some real smoking feedback. I was hoping to get at least the cost of materials back so please pm me if your interested and we can work something out.
