I see this link:

http://www.hpmuseum.org/cgi-sys/cgiwrap/...ead=153539

Someone knows where to find that book or any technique of restoration? I have an HP 16C with the HP logo a little deteriorated.

Thank you

Geoff Quickfall · 12-11-2016, 06:37 AM

Oh no! Another book request :-)

Very soon, very soon.

Show me a pic of your logo. There are sometimes spares and I think someone did one at Shapeways for the 15C. Is yours missing or just has the plating tremoved?

It never ends Smile

I'm planning two new replacement ideas for next year. Keep two chapters free!

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:

3). http://www.hpmuseum.org/cgi-sys/cgiwrap/...ead=139782

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.

You may also try a silver leafing pen such as this one.

But with that technique of the pen could be wear out easily or not?

I don't know, I don't have tried it on a Voyager. On my HP 55 it has not worn out.

Looking that link on the first post to some old thread... It did jump to me, have anyone tried a heated (by external flame ie. with spirit lamp) flatnose pliers to deform those heatformed attachment points that are used many, if not all the older hp-calcs..

If you are talking about the heatstakes then yes, remelting is possible if enough of the heat stake was left. I use a solder iron to mushroom the remaining stake and add glue.

Others have used TINY screws!

Geoff

Silver leaf pen and etc. do wear on surfaces exposed to wear. The badge when slipped into the calculator sleeve or when sitting upside down on the desk will wear. It is proud of the bezel surface.

Hello everybody,

This thread has turned interesting in so many different ways...

I guess it to be rather pointless to ask Geoff for more specific data concerning the actual publishing. May he rest assured that many here do wait very eagerly and are weighing each and any words he is offering on the state of his project with breathless anticipation...

Two questions however:

I did not find any voyager logo on Shapeways. Did the offer vanish?

More generally: i do know that the spires of this august forum tend to be rather sceptical of the practicability of 3D printing and do admit that printing materials and quality might still be imadequate. However: When might we see some of the oft-worn parts like e.g. the lower half of an HP-41 shell being offered as sturdy and unobtrusive 3D facsimiles?

Thank you for opinions,

a.

Publish date...

There are a few 3D printing offers out there for HO parts:

Classic battery hatch clips,

HP 41 battery hatch covers,

HP71B module covers and fram card reader covers.

Hp34C series battery hatch eps.

The voyager badges don't look 3D printed, but cast. I do remember someone thinking about them but cannot find the link.

I just designed some buttons out of metalized plastic (aluminide) for my Seiko QC-951. I see thay sell for $18 dollars a copy, I may get aluminum printed now, if the plastic design doesn't need tweaking, for my clock.
