I've been asked to restore a German Gramophone and Typewriter type 6. It's the second one from the bottom in this gorgeous picture:

The list of things to do is quite impressive:
- Motor Board and turnplate: Rust removal, polish and nickel plating.
- Turnplate: Install new 100% wool green felt.
- Brake:Rust removal, nickel plating and new brake pad.
- Speed regulation knob: Make a replica. Nickel plated.
- Repair winding shaft hole: Recreate moulding in wood and close holes.
- Bottom mouldings: Recreate missing moulding in wood.
- Turntable shaft: Repair missing threaded part.
- Record holder: Replicate the missing nickel-plated record holder.
- Screws:Replicate missing ¼ 24TPI round head screws. Find suitable wood screws attaching the motorboard to the case.
- Wood case: Repair broken screw holes.
- Speed Governor: Replace springs.
- Unwinding spring: Replace broken spring.
- Fiber gear: Replace 144 teeth fiber gear.
- Mainspring: Relube mainspring and check the weird rivet that holds it. Replace spring if necessary.
- Motor: In depth clean, rust removal and tune up.

Upon arrival, I carefully disassembled it, labeled and started organizing the restoration.

I disassembled also the fiber gear and you can see the heroic fixing attempt that someone did in the past!

Stay tuned!

Only some minutes today to work on this so I started to study the bottom profile and check if I have the suitable router bits.

I've just completed a replacement centre spindle with thread on my Style 11 single spring motor which has many similarities. Took me 3 attempts to get the clearances correct to stop it rumbling, but have got there in the end. Used an M10 steel bolt as my metal stock bar. Square cross-section leather shoe laces for the governor pads (soaked in oil for a new days). Lovely project. Envious!
