STAIN-LESS STEEL.......DYNACO CHASSIS'S......ST-70 and MK III

Will, did you try Marksman?

If I were you I'd be looking to Portland or Seattle for someone to made the chassis. That will keep your shipping cost down. You might get a local to do it too but I suspect they are mostly serving architectural concerns.

Will, we've done stainless chassis at Marksman in St. Michael, MN

Of course you'll need a good drawing, preferably in some sort of computer file, like a DXF. But they can make parts from an actual drawing- don't send it on a napkin :)  my advise is to get only a very small run done at first; if there are bugs in the chassis or drawing you won't have paid for a big pile of them.

If you really want to be classy you can have the corners welded and ground- then have the whole thing polished.

One thing to keep in mind- you might want to do this in steel with a chrome finish because stainless provides almost no shielding. We get away with using stainless because our amps are fully balanced and differential, which prevents a lot of noise pickup so we really don't need the shielding.
