Hi all,

I've been asked to restore the carriage of this beautiful EWC phonograph.

The carriage is made out of pot metal and has swollen, cracked and falling in pieces making this machine otherwise in pristine state unusable.

It's also missing the swivelling connector for the reproducer and the sliding tube is an heroic restoration attempt done with several pieces of a telescopic antenna.

I dismantled it to see what could be saved and start taking some measurements.

Then I took all the necessary dimensions from the phonograph and drawed the necessary pieces that I need to fabricate. I will use the Bengali reproducer I restored some weeks ago.
As you can see, The red piece is the pattern of the reproducer, the pink one is the swivelling arm with the tongue for raising the reproducer and the green outlined one is the carriage.

It's going to be a very nice project!

I have materials to do more that one so if anybody else needs one please pm me as it will be always cheaper to do a small run than doing a one off.

Best regards,

Pedro Martínez

Finally some progress on the carriage!

So after taking all the measurements and figuring out the procedure to build the carriage, I transferred the measurements to a piece of brass.

Then I started the long process of chain drilling it to make a very rough piece. I could have asked to make it with a CNC mill but it was expensive and It somewhat makes no sense to me to use CNC repairing a +100 years old machine.

Then a 12mm hole was drilled and reamed to hold the sliding tube.

Some files and much elbow grease turned the perimeter smooth and nice.

It's still thicker that needed but I will take care of that.
A first test to check all the dimensions turned out very well.

That's all for today. Next steps is to thin the main body and fabricate the lower "ear" that holds the roller and the upper tube for the reproducer and horn.

Stay tuned!

Regards,

Pedro Martínez
