Question

Would prefer word to word as close as possible , so i can do a reply.Many thanks Daniel.

Voor degene die zich afvraagd waarvoor de pijltjes op de laatste foto zijn, dit vroeg Daniel zich ook af. Ik heb Daniel op een ander forum laten weten dat deze schroeven zijn om de minimale opening van de balg te regelen. door de schroef in te draaien sluit de balg minder ver, door de schroef uit te draaien sluit de balg verder. Hiermee kan hetgeen bediend moet worden erg precies worden afgeregeld.

Een van de vele mooie details in Hupfeld instrumenten.
