The gap on my Holton T101 is about 1.4 mm. The ledge is very thin. There is also a visible solder blob of about 2-3mm a cm or so after the gap. The trumpet sounds very bright and resonates so much sometimes that it seems to choke up the horn even tho it can be pretty loud around middle c-high g
I have done extensive experimenting and research on valve alignments and have concluded the following: 1) alignment in the up position is much more important than the down position 2) alignment within .020" is usually acceptable for most players due to the design of piston and casing port bevels 3) not all horns were designed with piston/casing bevels so alignment is more important on these specific instruments 4) valve alignment is considerably less of an issue than mouthpiece gap for many reasons including; air flow & impedance change at mouthpiece/venturi is dramatic, valve alignment factors are too far from the player to be as noticeable 5) I have intentionally blind tested hundreds of players who believed perfect valve alignment was not even noticeable
Very informative and clear video. I'm fairly new to trumpet playing and was wondering about the issue with gap and flugelhorns. Do the same principles apply? My flugelhorn leadpipe does not have a receiver per say, it's just a straight in leadpipe.
The 5MM Modular Mouthpiece is now available in Bach sizes, though our retail packaging is not ready. We will ship most sizes within 4 weeks of your order in delrin and brass.

Why is there no gap on a flugelhorn?
Some flugelhorns and cornets have gap and others do not. It really depends on the design of the receiver.
The VGR is a considerably better solution, more info here: www.whyharrelson.com/store/c24/Venturi_%26_Gap.html
