hi Kinya,

ive been collecting vintage Echo supervampers and marine bands for a while and am looking to customise them. 

I've started practising on some mb's, and find milling the reex plates fine. But struggle to mill the cover plates, any recommendations.

also when removing nails, what's the best way to ensure that the reed plates dont bow? I'm using custom combs and want to ensure tother maximum airtightness.

much appreciated

Gareth

Hi kinya

so basically I'm trying to drill where the cover plates had nails to replace them with screws. Im using a mounted dremmel with and drill bit that I progressively increase to 2mm. The metal gets extremely hot and tarnishes the cover plates as well as leaving a large indentation on the underside requiring sanding. I was just wondering how you would approach this to minimise damage to the cover plates. Thanks

Ah so! I get it now.In

Ah so! I get it now.

  1. In general, drilling into sheet metal is always a tricky proposition (creates oblong holes, lots of jiggy jaggy stuff, etc.)
  2. I found the high RPMs of a Dremel difficult to control the bit.
  3. Using a small drill press works much better, if you insist on drilling.
  4. The best solution I have found, however, is to use a sheet metal punch. The make/model offered by micromark.com works well. I've owned and operated mine for years. The holes will look "factory".

The Metal punch looks like the best way forward. Much appreciated,
