Pre War Style Marine Band Cover Plates

Back to the Maintenance, Repair and Customization Room

Jan 29, 2009 1:49 PM GMT
When you open up (fold back) the covers on a Marine Band do you just use a vice?
That's what I've been doing and it works pretty well.
I just wondered if there's a better way to do it?

Thank you for any help you can offer.

I'd send you to the video directly, but my computer thinks I'm in Turkey right now... youtube is banned in turkey and I can't get on, thus I can't get a link or embed video. Can somebody please go to Youtube and get my "prewarify" a Marine Band video and embed it here? If you type in "prewarify" in the youtube search engine, it ought to take you there and the vid will have the embed info at right. Thanks in advance.

You can also use a hammer and a block of wood.

Hi Mr Payne.

It seems to be missing off your "YouTube" channel. Maybe it's one of the ones that accidently got deleted a while back?

I'll try the hammer and wood technique. I'm currently using a vice with hardboard attached to it's plates (teeth?) so I don't mark the cover plates

I just put the back side up against some wood and tap it flat with a hammer!

I think the hammer and wood is how they used to do it, you know, in the day.

I use duck billed vice grips cut down to the width of covers Im bending. I have several sizes.
But you will need to file the mating surface's flat as only the outer ends make contact. Its not a lot of filing really. They do a great job.

From Mel Bay's site:

"Long time readers of Monster Harmonica Workbench know I’m a
huge fan of opening the back cover plates to improve the voicing of the
harmonica. Use a 12oz polyurethane hammer on a PVC type cutting board
to impact roll the folds of the cover plates flat. This technique will
produce dent free “factory” results."
