Default GECoPhone BC 3235 Restoration Advice

I have recently acquired a GECoPhone BC 3235 circa 1931. The radio is in need of some restoration to the case aside from the electronics restoration/repairs. There are odd bits of veneer that want stabilising or replacement. But for these who know this model, the (I assume) bakelite grill has become broken and lost over the years. I have managed to find photographs of how it should look and the two ends remain, so I am guessing it might be possible to recreate the missing item. I was wondering if there is someone who has had a similar dilemma and has a process to do this. Any advice would be much appreciated.

Could be a job for a decent 3D printer. If it's actual wood, though, a fair bit of painstaking fretsaw and Dremel work with careful sanding could get somewhere near.

Or replace it with something simpler that lines up with the bit that's left just to break up the large flat area of speaker grille/cloth.

Having just casts some plastic knobs ,I was surprised how easy it was , I was thinking if that is a big if! you could borrow an original one , take a plaster /silicone cast ,you could make a very good copy. Mick.

Cut up, glue and paint plastic chopsticks? Maybe sand one side rounder.

Hi All, Thanks for the replies so far. The original material looks to be either bakelite or ebonite, very dark brown in colour. Love the chop sticks idea, could be an answer as the rays are tapered. Failing that, as suggested cut one from wood. As I have the two ends I know the thickness and profile of the rays. I doubt if I'll find another one to copy, and my 3D cad skills are somewhat limited. I like a challenge though!

Hi All, I Thought I might update my post with regards the GECoPhone BC3235 I have been working on. A big thanks to Mike Watterson who suggested the idea of using chopsticks to fabricate the missing fan grill adornment on my GECoPhone. I have completed my restoration and the attached photos show my efforts. As was mentioned on another thread the radio actually works without any further intervention other then a good clean. The valves are not period unfortunately but I'll keep my eyes open.

Looks lovely and ta for the credit. We have always had plastic and bamboo ones in the house since late 1970s or early 1980s. Some may be the originals and have gone "globe trotting" with us.

That looks very good, impressive job! In fact my wife, who is incredibly fussy and not the least bit interested in radios gave it her seal of approval. High praise indeed!

WOW! that is brilliant, who needs 3D printers when you are about with chopsticks and glue? Were you able to get an original to measure? No doubt it took a lot of effort and skill. Well done.

I am guessing he was working from the very clear auction image in post #1

Thanks for all the comments. I was working from the image suggested, plus I had the top and bottom bits for sizing purposes. Itís one of the things I love about this hobby - having to make do and mend. Keeps the mind agile.

Amazing job, I would also enjoy hearing more details of how you went about the chopstick restoration.
