OK, I've wanted to play concertina ever since I heard/saw one at the local Yankee Pedler festival in Canal Fulton, Ohio. So I bought something economical off of ebay... "...a charming vintage Scholer..." What did I know? Now, after a month of ownership (and the discovery of the concertina.net, etc), I see that perhaps opting for 'inexpensive first instrument' may not have been wise. Anyway, 'greedy accordian reeds' aside, I'm finding my biggest hurdle when trying to play the songs out of the beginners' songbook is when I run into a string of all push notes or all pull notes and I need to refill or dump the bellows rapidly. The thing acts like it is strangling for air. So, (hey, it's only a Scholer), I took screwdriver to it and opened the end. The air vent is miniscule! Can anyone tell me why I can't take my Dremmel hand tool and enlarge that? I can find balsawood at a hobby shop, glue on some chamois and fashion a larger valve cover for it. Doesn't look like it would be that hard of a job. Any suggestions? Warnings? I figure, this is the one to experiment on. And why do my reeds look like someone has glued a couple of harminicas to a soundboard? The inside of the Scholer doesn't look like anything else I've seen posted on this site or elsewhere... Thanks all!
