HP Restoration

[Geoff Quickfall]

Hello,

The badge is easy to remove and is of two types. The early badges were stamped metal, polished and painted on the recesses. They are easy to restore.

Yours is problematic and have been a source of frustration for many, leading one member to make metal ones at Shapeways I think, but for the 15c:

1). http://www.hpmuseum.org/cgi-sys/cgiwrap/...ead=172067

2). http://www.hpmuseum.org/cgi-sys/cgiwrap/...ead=200553


Back to yours, they are vacuum plated chrome on plastic, similar to internal car fixtures. They may be painted but the paint wears and is not robust.

There is this alternative; I actually removed them, then polished the plastic to remove the remaining chrome plate and painted the recess with black paint creating a negative image:

To remove one you need to cover the lcd display with a cloth and apply heat to the badge (a hair dryer will suffice). When the badge is hot to the touch the contact cement will release allowing you you to pick the badge out. I then give the face of the badge a polish using plastic polish (motorcycle windshield polish) removing the remaining vacuum plated chrome. Then repaint the originally chromed area with silver, for plastic model, paint. Or reproduce the negative version I created which will never wear (URL #3 above).

Sorry, couldn't be much more help but I will post this also and see if someone has created a metal bagpdge at Shapeways.
