Thanks!

Any advice or tips on how you did it would be gratefully received :D

Okay so you will need a wire mesh type pen pot this will give you a proper curve and cut out your ear shape.
then you will need wire flex from an old appliance or such like, then cut out one of the live or neutral wires.
This is the fiddly part, slice down the length of it but not right through, and clean out the copper wire inside.
Use to put over the Edges of the ear pieces, then use metal hoops like small keyring ones to make your antenna parts. Hopefully that all made sense, use shapeways to get the ear bases and use wooden Tees cut down for the bumpy part they sit on.

That's great advice.
I was wondering how to get the curve.

Thanks for your help :D

The main body was 3 mil hardboard.
The recessed panels & the back are 2 mil Hardboard, which is so thin, It's really easy to bend.


A(nother) noddy question - with the hardboard that thin (especially the 2mm) is it tricky to cut?  Probably years since I've cut it but I have memories of it just wanting to vibrate wildly up and down on the Workmate and slapping against the base of the electric jig saw while cutting.  Weighing it down with things only worked so much; do you need to clamp it to the surface?

I did the whole cardboard-boxes K-9 thing at primary school.  I know your progress makes it look easier than it is for novices, but if a hardboard K-9 had seemed like a viable option back then I would have been pestering my dad no end.

Don't you worry- ask away! That's why we are all here!

Yes, the thin board does wobble & vibrate like crazy. Plus if the bit you are cutting off is too heavy it starts to tear away.
And I don't even have a proper workbench, just a small round garden table.

I just use a fine sharp saw & take things very slowly, just doing a bit at a time until the cut is finished.

One upside is that if the cut s a bit ragged, it smooths easy with a bit of sanding.

Hope that helps.

Regards,

Russell

I found that to cut thin board like 2 -3 mm, using a Stanley or retractable knife & do multiple cuts till you get through it works well too & come out a bit neater, just make sure you don't try to cut too deep each time & use a steel straight edge (e.g. steel ruler) to get that straight line.

Hope this helps,

Chris.

Agreed, but, given that I've got so many scars on my fingers and hands that the fingerprint login/out scanners at work won't recognise me, I'd recommend using a steel rule fitted with a handle or hand-grip when using a knife. Keep those fingers & thumbs well out of the way!  ;D

I do like your K-9....
But I have to say I just can't stop staring at your console...
If you ever hear a strange van pulling up in the wee hours- lock your doors!!! :o

Yes, Chris & Tony,

I did completely forget to mention that I did sometimes score the lines with a craft knife & metal ruler to make it easier to cut after.
For the fiddly bits I sometimes just used the craft knife, making multiple cuts until it went all the way through.

Thanks guys!


Cheers,

Russell

Don't know if these images might be of any help

Plus this video may be of interest. Ear build at 54mins 25sec in!

Thanks Saintcar!
That will be very useful.

One of the things I love about TARDISBuilders is that everyone is so helpful.

I watched your video... beautiful job. ;D


Thanks!

Russell

saintcar

It's not actually me in the video!
But we've found it inspires a lot of people to just go for it when thinking of building anything. You just have to be brave and start.

Good luck with your own builds
