Gimbal-mount for old Swedish compass

I got this compass for no-money on Blocket. It was clear that gimbal mount is broken so no surprise when it came in pieces.

It is a traditional, old Swedish Silva compass, entirely made of black-painted brass. The only parts which were made from bakelite are compass ring and bulkhead mount. Both of them broke, probably due to age.

As it should be - the compass housing has adjustable magnets, to compensate for deviation.

New bulkhead mount will be made from mahogany - I will hang it in place of non-functioning VDO log.
Instead of trying to glue the ring I’ve decided to make it from brass. I took measurements and sent drawings to my friendly workshop in Poland. Today I got the part delivered.

New compass ring, brass, with original brass screws - one missing. Old, broken bakelite ring was used to make drawings

I’ve specified ring finish “as machined”, so it took me some elbow grease to polish visible surfaces. Brass will develop patina after one season so it will match original parts better.

I’ve assembled all components - the ring fits perfectly!
The compass housing is mounted to the ring with several brass screws. Washers hold the compass securely in place.

Entire assembly is then hanged on brass gimbal.

I needed to slightly modify the ring - it turned out that it is too tight to mount gimbal screws, just 2mm. Easy to fix with drill press.
Name plate, originally riveted to bakelite, will be mounted on the ring with original, aluminium rivets.

Rivets are so tiny that pressing them into freshly drilled 1.3mm holes was a challenge.

All assembled and ready to be mounted on Meritaten.
