Embossing the reed slots of a harmonica (With quality control)

This is how I approach embossing. You get the idea with this quick video.
Is your embossing tool working?
Sometimes, your tool can become dull or you may not use it correctly - here is a trick to make sure you are actually getting the work done.
If the tool is dull, I show you how I dress up the embossing tip.

hi andrew, do you generally do both sides of the reedplate when embossing?

[@Justin-hb9wc]

i don't get how scraping the reed slot makes the reed slot smaller

Andrew is actually 'swedging', by wiki: "To shape metal using a hammer or other force.". In the case of the reed slot, from the edge of the slot is into the slot and there by making it narrower, closer to the reed. All of that effort is to reduce the air flow an around the reed and better direct it to the reed thus improving reed response.

I wish harp manufacturers offered factory embossed harps... I’d pay extra... I do anyway
