Adding 9mm Filter

[AroEnglish]

I’ve been wanting a Peterson Derry with a 9mm filter just to try what filtered smoking is like. I know I can get them at SPE but there aren't any available that appeal to me. There are a couple that appeal to me at SPC but they don't accept 9mm filters. What would it take to drill the stem to accept a 9mm filter?

If you have that skill level, it could likely be done. However, there are so many 9mm filter pipes on the market, it seems like unwarranted effort.

Because 9mm filters aren't as popular in the U.S. as in Europe, we sometimes get pipes in various quality brands for sale in the U.S. for somewhat discounted prices, I guess an overage from Europe.

I'd look for those deals rather than modifying a new Peterson to the purpose, unless that is something you feel you can do easily.

Whether you drill out a Peterson or find a readymade alternate brand, I think most 9mm filter pipes smoke well without the filter, in case you decide later that the filter isn't worth the bother, or is only wanted occasionally.

I have a Kemperling smooth bent Rhodesian, an Austrian pipe, that takes 9mm filters, and it smokes perfectly without them too. I have a supply of the filters but rarely use them.

Take a look at SP's pages on Vauen pipes. They have 9 mm pipes at many price levels. Beginning on page 3 under Vauen pipes, they have a number of 9 mm filter pipes in various shapes for $70.13, which would give you a chance to try out 9 mm and would still probably leave you with a smokeable pipe if you leave out the filter.

Like my Kemperling, Vauen pipes are produced with high fit and finish and good quality all around. I'm not sure what the 13 cents is for, maybe good luck.

So you have never smoked a filtered pipe but you have a very specific one in mind, to the point you would drill it out yourself, just to try smoking a filtered pipe? Seems odd but you do you eh.

Does it make sense to drill a pipe to 9mm to fit a filter? You can of course drill a 9 mm hole in a shank, but then you have to drill a new mortise too and you also have to drill the stem up to 9mm. Because one part of the filter is in the stem. And the tenon has to be at least about 11 to 12mm in diameter to do that.

If you have lathe you can try this, otherwise I doubt that you can accomplish the precision needed.

Imho it’s better to buy a 9mm filter pipe already as @mso489 pointed out, Thera are a lot out there.

3mm to 9mm

Why not try a pipe with a 6mm filter? They're pretty common. Heck, buy a cob. Much cheaper way to get the data you want.

This is all I was looking for; thank you!

 

[AroEnglish]

Yeah you guys are right, this is actually not worth the hassle. I know eventually I’ll find one that I like and there’s not need to be hasty and impatient.

That being said, please continue giving me your sage suggestions.

I second the Vauen recommendation but also try SP.eu which is the sister company that tends to have more 9mm filter pipes. You might find a Peterson there.
Sorry - just re-read OP and saw you tried that --- just wait a week or two and one will show up.

Briarville has done some 9mm conversions in the past. You might want to give Rich a call.

Try visiting the website from The Danish Pipe Shop - use the filter function and source for 9 mm pipes.
They have a lot - also Peterson.

Have you looked at Savinelli's balsa wood filter pipes? They are nice pipes and can easily be smoked without the filter, if later you decide filters are not your thing.

The short answer is no, it cannot be done. The long answer is yes anything can be done with enough time, money, & talent.

First you need to understand a few thing about 9mm filter pipes.
1. They tend to have larger shanks.
2. They have much larger tenons.
3. filter drilling is not just making the hole bigger, it also involves drilling to the correct depth , in both the shank and the stem.
4. The tenons in filter pipes are generally UHMW. Delrin. or Teflon.

To convert a pipe you need to cut out the old tenon and drill the bit for a sleeve tenon to the correct depth.
Glue in a UHMW, Delrin, or Teflon tenon sleeve. Then drill the shank to correct depth and diameter to accept a filter/filter tenon.

Most pipe tenons are somewhere around 7-9mm to start with so drilling an existing tenon is typically not possible. A filter tenon is usually around 12-13mm od, but even if you found a pipe with a 13mm tenon you could not just drill out that tenon if its vulcanite or acrylic because they typically wont last if they are that thin, they'll snap off.
So you would still have to glue in an UHMW, Delirin, or Teflon tenon. At that point it's basically easier to start with a new stem, but if your exsisting shank is already drilled to deep than its all for naught.

So could your drill a non filter pipe for a filter? Yes if you found just the right pipe that meets all the requirements and you're willing to either pay someone to do the work, or you have all the equipment and are capable of the complex drilling and machining required.

Personally I hate filters, I have exactly two filter pipes. One Peterson and one Savinelli. Both are outstanding pipes. Both smoke like crap with filters.

Haha, my recent meer had a 9mm filter. This is all anecdotal and personal, but perhaps it will add to a data point. I absolutely love the balsa filters.

I’m not going to get into the science behind them, as frankly, I’m a little skeptical, but, they do filter, and if they don’t come close to their claims I believe they’d be liable to some lawsuits, although I’m not sure about that.

All that being said, concerning the smoke itself, I’ve found a slight (very slight) “shifting” of the flavor, but no reduction in taste. For me, it’s as if you were listening to music and adjusted the ranges a bit differently. Furthermore, any irritation in the back or roof of my throat/mouth virtually disappeared. I sip my tobacco, and smoke slowly, and to be honest, never really noticed the irritation until I tried the filter.

I’d second the cob with a 6mm as a way to test this all out. If you’re like me, you’ll love it. If you’re like all these other curmudgeons (spoken endearingly) you’ll return to this post and request I pay your 12 cob costs. Best of luck!

My ruminations on the subject of stingers, filters, and other such airway gadgets.

They all work, and too well for an old codger like me.

E A Carey system pipes work the best.

Then the 9mm filter.

The rest are all below.

I own a few Carey’s and 9mm filter pipes, and as a change of pace smoke them.

But I like more nicotine, I surely do.

Thanks for the thorough explanation, RP. This puts the nail in the coffin for my thoughts of converting a non-filter to a filter. The pipe I had in mind was the Peterson Derry line which has 9mm options on SPE but I found one without a filter I really like on SPC and was feeling impatient to wait for a nice one on SPE with a 9mm. It's clear I should just wait it out instead of making more unnecessary work for myself/my wallet.

I forgot to ask, do you smoke them with an adapter or not?

I have made adaptors in the past, but found that it didn't make any difference. I don't use one now.

The European vendors are the best source for 9 mm pipes. Besides the Danish Pipe Shop you might look at Haddocks Pipe Shop (dutch) and Cigarworld.de (German). Both have many filter pipes.
