The Fine Things are Always Hand Made

These were copied from a plastic bezel and made by electroforming

They look good. And are a proper looking bright shiny polished brass color.

Did you have to polish them for that shine?

Thanks for the compliment,

yes they have been polished with simichrome as they are matt when they are removed from the mold,

parts that are difficult to find in the USA are almost impossible to get here in the UK, that's the reason for making

You do beautiful work. making the knob set is a work of art.

Comment by Scott Seickel on May 10, 2018 at 9:06pm

Nice.  What material did you use for the mold, how thick are they and how long did the electroforming take? 

It would be nice to make a set of dies for the Scott radio stuff and have a run stamped out.  Lots of sets in need.

Scott:  I believe Mike used the process he previously described at

Norman, you are correct, the process I posted "homemade escutcheons" was used to make these,

it does produce excellent results, if you look at the bezel on the right you can see a line between the mounting hole and the dome, also there is a scuff mark on the bottom edge, these are on the original plastic molding,

thanks for posting the link

Did you have success Norman? 

Comment by Norman S Braithwaite on May 11, 2018 at 8:10pm

Yes.  I have reproduced eight "radio-phono" escutcheons for the AW 27 and Quaranta but have yet to gold plate them.


Comment by Scott Seickel on May 12, 2018 at 9:20am

Caswell sells nickel electroforming kits.  If the escutcheons are to be gold plated, I would think that creating the base from nickel would eliminate the nickel plating step and these could be directly gold plated.

Any thoughts on using this process to make tube shields and coil covers?  I guess that the setup would be a little touchy as the anode would have to be inside the cover mold.

The process uses Acid Copper, the bright copper alkaline solution peels during plating due to internal stress building up literally tears itself apart, I have not tried the process with nickel as the solution needs to be kept around 100f for optimum results,

maybe worth a try with the caswell kit you have mentioned.

the copper parts only need a flash of nickel to stop the gold migrating into the copper,

the next time I am using the nickel bath I will try to form an object.
