Hi mates, thanks for the add. I’m trumpet player and need your help, please.
Just for curiosity and not for my comercial purposes. So, there are any measures between the drills ? I know that it’s all about brands and his personal work but just checking out how they really work and how it’s this made.
Thank You All. link text

Btw, Jason Harrelson seems to have different measures standards:

Jason Harrelson seams to have different but in fact HE is right. If this foto is from him, he work on sequencial measures and drills. From 0,005” to 0,005” all over up and down on his drills, we can see it.
.130
.135
.145
.150
.......
and not the Industrial Global Drills;

.128
.136
.140
.144
.147
.149
.152
......

@Trumpetsplus precisely. That’s why I found the un-sequencial measures from one drill to another. It’s not a issue. Just want to know more and why. Cheers

@PortugaHorns : Now I see it - and yes, Harrelson's 5MM makes more sense!

Now you get it. Thanks for the support. Cheers.

@Trumpetsplus I play on my custom mouthpieces. You can see it on my personal table / chart. I love my 5mm. made a re-shape on cup and backbore to balance the drill. What a sound and easier airflow. Better lower range and highs, resonance at full capacity with awesome dynamics. I haven’t a clue that was #8 Drill. Now I’m better informed and still searching and trying new approaches.

@pss it’s not for comercial purposes, only my own use. If you are in Lisbon, you can tryout. Cheers.

@Trumpetsplus I know how it works and how they have/are been made. Many folks are “dreaming” on Drills or shallow/deeper Cups, backbores, but seams to me that this are all wrong. I think this matters it’s all about Balance All Parts. Drills are just the Vertex.
My experiments made me realize that isn’t just the hole / Drill that have importance, or Cup, or backbore, but the “shoulder” of Cup ends and backbore starts. Even the “Neck” = Length Throat are very, very crucial.
Thanks for sharing and replaying or thoughts.

@pss you can check the space between each drill and find out that they aren’t sequential. Numbers yes, but it’s measures not. The difference In mesure of each one aren’t equal, so, they aren’t sequencial. Millimeters or inches aren’t the problem. The real issue it’s the un-sequential mesures in mouthpieces rules, creating all this questions and differences in brands and approaches.

@Dr-Mark thanks for replying. I wasn’t sure if my chart was correct. Thanks.

@pss in fact, on my face post I made a trade. Bach are on 3,66mm & Yamaha on 3,65mm.
The thing it’s because there are some differences on #25 drill, some have .149” others .150” inches, all of this it’s about 3,80mm. but the measures differ. Bach haven’t the #23 Drill, why not ???
Other personal question was, what are the 28, 29, 30 drills played on Chase, Brisbois, Wayne Bergeron or Vizzutti, Jon Faddis and so on.

Brands don’t want that we know and don’t tell all the information. This it’s a fact.

If the Drills are a global standardization, why not the Mouthpiece Drills ? Get me ?

Cheers and Thanks for all.
