Default HMV gramophone restoration

Hello everybody.
Well I have my work cut out for me but I just couldn't let this little gramophone rust to nothing and then get dumped. I'm fairly practical, so I'm sure I will be ok.

I don't know about penicillin, but there's definitely a cure for something in that mould!

Wear gloves when you clean it.

Hi Steven, and welcome to the forum.

Wear a mask when removing the mould, and don't use bleach, it'll take the colour off the covering fabric. Apart from that, I can't see you having many problems with this. It's easily the one of the most common machine around today, due to its' popularity when new, so spares are readily available. I have restored and repaired literally dozens of this model over the years, so if you need any help, don't hesitate to ask.

Barry

Hi Steven - I've restored a couple of HMV gramophones from this period and you will find a wealth of advice, knowledge and skills on this Forum. Pleased to read that you are not too daunted by the task in hand.

As well as the obvious problems with mould there are worrying signs of rust on the top board fittings and fixings - hopefully this is cosmetic and can be treated accordingly. I do worry though about what you might find once you remove the top board (be careful not to get that wet when you are cleaning) please Post some more pictures of the motor and spring case.

Please promise not to open the spring case but send it off to be cleaned and re-greased by someone who knows what they are doing!

The Rexine covering will also have come away due to the dampness but this can be cleaned and reattached using PVA - but that's further down the line.

As Barry says, there are lots of sources for spares for this Model 102 so you wont be stuck.

Notwithstanding the excellent support on this Forum from the likes of Barry, these two websites developed by the late Graham Barber are a treasure trove: -

Keep us updated please ...

Thank you everyone for your kind remarks. Did some more stripping down today and although the motor, horn and sound head (?) are ok there is lots of rust and the fabric covering is trashed. Glued some of the casing together as it seems the player had sat in a shed being rained on for years. Lots of chrome lifted and rust underneath, sigh.

I can just glimpse the motor casing in pictures 2 and 3 above and it doesn't seem too bad - good news! Will be very interested when you delve inside.

I tend to concentrate on the mechanics first i.e. motor, spring, brake, spindle, tonearm, soundbox etc. but this is just my way of working.

There are many sources for replacements for the Rexine covering although it will be difficult to replicate the embossing. I'm assuming one casualty will have been the HMV logo?

If the gramophone has "sat in a shed being rained on for years" then the external wood casing may be warped?

I do love a complete disassembly!

The board on which the motor, horn etc sits, is delaminated and rotted. I may be able to save the uppermost lamination to keep the vintage look.
Many screws that screw into metal have rusted and some snapped or rusted off, so this may entail filing back to be able to access the hole and clear/rethread it.

More work done on the gramophone. Dismantling and cleaning rust off, listing water damage etc.

That's a pity - this I think is known as Essex Board which consists of thin layers of paper glued together rather in the fashion of plywood but without the weight.

It's very light and is prone to de-lamination if it gets wet - your plan to save the uppermost layer is a good one if it is practicable.

As for the screws, hopefully Barry or someone else will advise on those?

The top layer is plywood layers, the bottom is Essex bboard as you say. The board is intact but bowed slightly.

Hello again.
On further inspection a few of the chromed parts are rusted and have bubbled up the chrome plating. Seeing as most of the parts are joined / hinged together. Is it work rechroming or buy replacement parts or just clean up and varnish?

If you get stuck on getting replacement parts, I know a firm near me that specialises in re-chroming.

I can supply the two studs in Picture 1, and the speed indicator plate. There are screws with the studs, but one of them needs to be shortened. The lid clasp I suggest you soak in some rust remover, and when all it is all clean again, spray with a satin finish black car paint. If you treat the 8 corner pieces, the winding handle escutcheon and the carrying handle ends in the same way,everything will match. There is an alternative, which is to strip all those pieces back to bare metal, and give them a few coats of gun barrel blue (available from the auction site) then seal with a spray lacquer. You will have to buy two different sorts, one for steel (lid clasp, handle ends and escutcheon) and one for brass (corners). It's a bit of a faff to do, but worth the trouble, as they come out as good as the original finish. Send me a PM with the postage details and I'll get the parts in the post to you.

Barry
