Hi again,

Before telling you about my progress let me show you a couple of important pictures about the leadscrew and half nut.

As you can see, the thread is not symmetrical. One side is vertical and the other slanted. The vertical side is the "pushing side" so it is very important to put the half nut in its correct orientation.



That's a buttress thread. Nice job reproducing it!

Sorry for the lack of updates recently. Tons of work and travelling do not help on the restoration of this Coquet.

After a long treatment to get rid of the woodworms and finding the walnut wood finally I felt brave enough to attack the restoration of the case.

The case was wrapped in film after being soaked in woodworm treatment and left in a freezer for several weeks. This is rather overkill but the last thing I want at home is a problem with woodworms.

The first thing I did was to try to remove the tiny screws that held the border of the lid. They were very rusty but I managed to save all of them.

Then the real battle began. Using very thing spatulas and cutters I started removing the most damaged parts and they literally disintegrated. They were held by the varnish most of them.

This are the pieces that I will use for replacing the damaged ones. You can also see the shellac and hide glue that I will use.

I have much more walnut wood so if somebody is looking for replacement piece feel free to send me a PM.

Stay tuned!

Some more progress this weekend.

I finish the tube that connects the horn to the reproducer. Its made of mild steel and the diameter must be 15,7 mm in order to fit the carriage and horn. The screws are 1,6 mm with the tip of the thread turned down a smidgen to fit as the axle the holes of the piece that holds the reproducer.

The horn I've managed to find had the mouth badly distorted. With a clamp made out of wood and lots of patience I manage to straighten and shrink it till its a smooth but tight fit on the tube.

I also started on restoring the reproducer and recorder heads. Both had the glass diaphragm broken and I've not found replacements. (If somebody knows a source for them please write me!). From previous restorations, I've seen that if you use a 0,2 mm thick mica diaphragm, the sound is very similar to the 0,3 mm thick glass. I needed to carefully delaminate some mica and glued with shellac the sapphire and cutter. Now they are ready to receive their gaskets and beeswax.

Thanks for the update... I love to see the results of bringing back something that appeared to be beyond repair.
