In Topic: Canal gps with map previous movement tracker

I use a Garmin GPSMAP handheld with colour display, typically with external 12 volt power lead although it takes AA batteries.  I added the UK database microSD card which shows all roads and canals. You can save routes and tracks.

You also try Francis Searchlights since the company still exists. 


In Topic: Francis lamp refurb

I have bought a lamp and want to get it polished. I quite fancy having it silver nickel plated but have been told that it's not a suitable finish for a lamp that is going to be mounted outside. I don't like chrome and I haven't got the patience to constantly polish it if it was polished brass. Any ideas anyone.

Polish brass then apply Rylard Incralac - available as spray in aerosols or brush on.

In Topic: Are these nuts meant to be tight?

18 September 2016 - 05:07 PM

The two nuts arrowed below are very loose (I can turn them with my fingers).

1. Are they meant to be tight?

2. Are there, perhaps, meant to be two nuts on each thread, rather than one on each?

 

The reason I ask the second question is that I have found a single nut of the same size on the bilge floor, beneath this part of the propellar shaft, and can only think it came from here. Many thanks for any help.

 

I suspect from reading other posts that you are getting confusing advice on this thread. The nut or nuts should be tight to each of the studs they are screwed onto, so that the relatively light pressure placed on the adjusting flange for the stern gland is locked. The adjustment is made equally each side so the flange remains parallel to the stuffing box and with the minimum pressure to stop any dripping, commensurate with being able to turn prop shaft by hand. The adjustment is then usually secured by locking two nuts against each other on each of the studs.

 

It appears on your photo that at some time the gland as been overpacked causing the adjusting flange to sit further out, and leaving a minimal amount of stud to fix two screws on. One solution would be to use a single self locking (nylock) nut on each stud that once adjusted would achieve the same goal.
