9mm Filter Option

[Richard Burley]

This is new to me; I hadn't seen it discussed anywhere. I personally don't have a problem smoking a 9mm pipe "naked" w/o adapter or anything else, but this looks as though it would slick things up a bit by reducing turbulence and gunk-collecting corners. I'm also wondering about a sort of calabash effect, if you get my drift. From eBay, seller avrylo_s, Moscow. The guy or gal seems quite pipe-literate.

Most of my American pipes take the .45 cal filters. This process might work for them too? :lol:

Richard, I am curious where you are smoking when you smoke your pipes naked and what the neighbors or co workers have to say about it. I seriously doubt a filter or tenon job will keep you out of trouble. :affraid:

I have actually talked and written about this quite a bit. Maybe not specifically with 9mm filter pipes, but certainly with pipes that needed modification.

There's flow dynamics to our pipes, believe it or not. I'm not sure why this would shock anyone, but the way mixtures of things move matters. Expansion, contraction, friction, turbulence, etc. Anyone that knows about improving performance on 2-cycle engines is a matter or controlling the exhaust, and to be honest, I think of pipes this way, too.

What this cutaway you've shown, in my experience, RB, will reduce the interruptions between bowl and bit. Smoke is lazy, like water and humans. They like the path of least resistance. When they don't get their way, they complain and cry. Humans make tears, and smoke makes moisture. Which in turn, makes more tears in humans with pipes.

It's a sound design. I have been "chamfering" the tenon bits in my pipes for quite a while. I have a unique way of doing it that rounds the surface areas even further, which is why I call it "trumpeting."

I'm confident enough to say this does something slightly different than the calabash and reverse-calabash methods of making a pipe. At some point, spaces for expansion, heat, moisture, particulate (smoke) and the flavors we crave have a limit-point, usually determined by the draw we take, or in other words, the capacity of our mouth. Very little space for a "calabash effect" is had when taking away so little material in a pipe, be it tapped for 9mm or just a standard mortise/tenon. What it does do, however, is streamlines the lazy smoke into happy smoke, which, in turn, creates happy smokers. The cool part of that design is that a 9mm filter could still be used if one so desired. I enjoy the fact a longer, deeper chamfer was used in this drawing. The less the smoke has to push against, the better.

Why more makers do not chamfer the stem's tenons (or chamfer them correctly), I don't know. Sure, cost & labor. So charge an extra $5--any one of us that is mindful can do a passable job with a pen knife or a drill bit. :lol:

Probably. I believe it's called opening the throat, or "throating" the barrel.

Well, since you ask, I have the physique of an Apollo, god-like in its perfection. No one complains much, and those who do are merely envious or lust-driven. Hey--you asked!

Dammit Kyle, I make a serious post and you have to come along and gum it up with some snarky response like some adolescent internet troll in heat or something. Why can't you be more like your two predecessors above, obvious paragons of something or other?

Seriously, I know quite well of your "trumpeting" tenons, etc., and have admired it and agreed with its premise. I just had not seen it used before in such a direct and obvious application to this area of concern, a concern at least to some of us. Great response, btw.

The only thing I've noticed in smoking a Filter pipe without a filter is it really
gets gunky in the tenon and shank area. Some do get a little gurgle but, I make a
filter adapter to take the place of the filter which I counter sink to reduce air
turbulence and machine it to accept a O-ring to make it a good and tight fit and
haven't had any problems with them.

His way may certainly work well also but, I choose to keep my pipes ALL original
and not change anything that I can't undo later. If one would wish to use a filter in
this pipe later, they might not be able to and a resale value may be lessen by it.

Thank you for your informative post. I may have to look I to getting adapters for a few of my pipes and see if it improves the smoking qualities for me.
