Drilling Mpc Throats

Mark Heuer · Veteran Member Joined: 23 Nov 2001 Posts: 232

I have a Rick Baptist Model E5 Marcinkiewicz with a 28 throat. I like the mouthpiece overall, but a 28 throat is pretty tight and resistant. If I open it up to a 27 or 26 throat, will it throw the mouthpiece out of balance (cup, throat and backbore blow resistance) or will it simply make it a more free blowing mpc? Thanks.

Damn that 28 must be tighter than a drum. Drill that bad boy out and don't worry about messing it up. When in doubt don't be afraid to make your way to the tool shed and say hello to Mr. Drill.

good luck

Mark - before you do that, I'll trade you my Rick Baptist model with gold plated rim with a drilled out 26 hole. I use to drill all my mouthpieces to 24 holes. But I've gone back to tighter mouthpieces.

David,

I sent you a private e-mail. We may have a deal (trade). Question: is going from a 28 throat to a 26 throat a dramatic change or hardly noticeable?

I agree with going only 1 drill bit size at a time. One additional consideration is that drilling out the mouthpiece throat can result in a longer throat, depending on the backbore configuration. Lengthening the throat has the opposite effect on resistance as opening the throat, so make sure you work with someone who knows what they are doing.

If you change the drill of the mpc, it's like getting a new piece. The resistance changes and you know how long it takes to get used to a new piece. At least that's how it is for me. If you wanna experiment, go ahead. But personally, I think most manufacturers have a formula and balance their pieces a certain way and opening the throat can mess it up. But I'm just an average bloke.

FWIW, Vincent Bach chose the 27 throat as the smallest size any player would ever want. He used to ship his mpcs with a reamer so the player could adjust it to fit. This has been documented (ITG journal article, but I'd have to dig so if you want to know go to the ITG site and look it up -- sorry). Now, I've heard the Bach 6, which I used to play and Mr. Bach designed for himself (only thing we have in common, 'cept I used to play one of his horns

), was originally shipped with a 26 or 24 throat (opinions vary) as that's what he used. With the company growing and trying to standardize manufacturing, all mpcs (including the 6) come with a 27 throat now.

FWIW - Don

Quad C is right. Get it reamed, not merely drilled. Coming from a tool and die family, reaming is a more exact science and needs an expert touch.

Having grown up (some will question that) in the cutting tool industry, definately ream not drill. A reamer will give you the correct size, drills tend to cut oversize, and a much rounder hole. A drill is designed to make a hole from solid, a reamer is designed to expand and correctly size a hole which is what you want want to do.

Might I suggest this approach. You must like something about the mouthpiece to start with - the rim and or a general quality of sound. Have the mouthpiece top cut and threaded for either Warburton or Tottle backbores. If you use Warburton you will have the throat of the top enlarged to 27 - if you go with Tottle (DiOrio) backbores you can leave the throat at 28. This gives you an excuse to spend most of your disposable income on backbores. I had good success with a Reeves 41S top threaded to Warburton and enlarged to 27. If you follow this approach it costs more money but you still have something you could sell on the MarketPlace.
