Das obere Ende des Programms
Größer wird es bei Spark nicht, und der Grund ist, dass Motorräder es nicht brauchen. Ein Bogen bei sechsundsiebzig Millimetern existiert für Hüllen und Kammern — die Teile einer Eigenbauanlage, die Volumen halten statt Gas zu bewegen.
Verlangt Ihr Entwurf einen Gasweg dieser Weite, ist wahrscheinlich der Entwurf falsch und nicht die Teileliste.
Eine sanfte Krümmung in einer großen Hülle
Dreißig Grad über einen 76-mm-Querschnitt ergeben einen langen, langsamen Schwung. Auf der Werkbank sieht das nach fast nichts aus; an einem fertigen Dämpfergehäuse ist es der Unterschied zwischen einem Gehäuse, das dem Motorrad folgt, und einem, das quer darüber liegt.
Umgang
Groß, im Verhältnis zum Durchmesser dünn, und von einem heruntergefallenen Schlüssel dauerhaft gezeichnet. Zwei Hände, eine freie Werkbank und sonst nichts darauf.
Enden rechtwinklig schneiden
Rechtwinkligkeit zählt mit wachsendem Durchmesser mehr: Ein halbes Grad Fehler über sechsundsiebzig Millimeter sind fast ein Millimeter Spalt auf der Gegenseite. Ein Rohrabschneider oder eine Bandsäge mit ordentlicher Prismenauflage schlagen hier den Winkelschleifer deutlich.
Zusatzwerkstoff und Spalt
Bei 1,5 mm ist ein kleiner Wurzelspalt kein Problem — es ist genug Grundmaterial da, um ihn zu überbrücken, ohne dass die Kante wegfällt. Damit ist dies der verzeihendste Durchmesser im Programm beim Schweißen, was günstig ist, denn er ist auch der teuerste, wenn er misslingt.
Preis gegen Risiko
Das ist weniger als eine ruinierte Länge des entsprechenden Geraderohrs — und diesen Durchmesser ohne Dornwerkzeug zu formen erzeugt zuverlässig genau das: eine eingefallene innere Ferse und einen ovalen Querschnitt, meist zweimal, bevor jemand aufgibt.
