druxey Posted April 24, 2017 #1322 Posted April 24, 2017 Oooh, nice! Also love the adjustable spanner (wrench) that you made lo those many years ago. Do I assume that the compass will work when completed? Otherwise you might just use brass for the balls (adolescent snigger). popeye the sailor, Jack12477, mtaylor and 1 other 4 Quote Be sure to sign up for an epic Nelson/Trafalgar project if you would like to see it made into a TV series http://trafalgar.tv

Otherwise you might just use brass for the balls Hi Druxey yes the compass will be fully operational. I spent some time this morning making some soft iron balls They turned out well but are way to small for the scale I am working in as i was doing this I realized that I did not fully understand the mechanism for the balls or how they worked. To be clear on the function of the soft iron Balls. I read a number of articles about binnacles and found the technical stuff surprisingly hard to find. This one was one of the better ones and also a child's article on making a compass has led me to rework the innermost parts of my own. This picture shows the parts of the compass I have made and also the tiny parts from a ridiculous pocket knife compass that showed the alignment of the pocket knife and nothing else. The pocket knife compass though has a one piece that will be able to replace the huge brass mass with the rare earth magnets. The cup hanging inside the gimbals will need a bit of modification to hold the black cup and compass base. I will make a new card to fit over the compass in the black cup, and rework the brass cup to have a needle for the new compass instead of the black plastic cup. The other thing that will need to be done is a cover that will prevent the new compass from lifting off the pin, there is enough meat in the brass cup to drill and tap some holes for retaining screws on a 1/32 plexiglass cover. The soft iron balls will no doubt wind up in the spare stuff tray. Looks like a bit of lathe work is in order.

realworkingsailor Posted April 25, 2017 #1324 Posted April 25, 2017 Very nice compass! The purpose of the iron spheres is to help mitigate the effects of an iron hull on the magnetic compass. There should also be a vertical iron rod (the flinders bar) to offset that component of the magnetic field. I hate to break it to you, but since your hull is wood, I doubt that your compass would have been fitted with those extras, they would do more harm than good.

Andy this is the conclusion that I came to after all my reading today. So they will not be installed and as I noted in the last post I just edited. However I think I will have a better gimballed compass at the end of the day as a result.

michael mott Posted April 25, 2017 Author #1327 Posted April 25, 2017 Hi Dan thanks for the kind words. This evening I reduced the depth of the inner cup and machined a new insert it is drilled through with a .6mm hole at the top and threaded 1/4 inch deep x 8/32 thread on the bottom. This allows the needle to be adjusted up or down, the needle is in fact the end of the 8/32 screw machined down and honed to a point to hold the compass. The magnetic part placed on the pin I tested the pivoting by bringing a pair of metal tweezers up to the compass and the needle swung to them Next to find the print that I made for the compass and mount it on the metal magnetic part. Also the plexiglass cover.

realworkingsailor Posted April 25, 2017 #1328 Posted April 25, 2017 Prototypically, the bowl of the compass should be filled with mineral spirits to dampen the movement of the card.

Andy this has crossed my mind, it would entail sorting a couple of things out, not the least of which would be testing the printed card for deterioration in the oil or spirit. also I would need to seal a few spots to prevent leakage, eliminating the air is not a problem.

michael mott Posted April 26, 2017 Author #1334 Posted April 26, 2017 Denis , Elmer , and Piet thanks for the kind remarks. Did a bit more work cleaning up the compass and made the cover from some 1/32 plexiglass. The bolts are some modified 00x90 1/4 in long hex bolts. After cutting them to length and polishing the threaded end they were held in the pin chuck to reduce the hight of the head and to round it up a bit. All the gimbal rings were given a final sanding with some 1200 grit wet and dry. and fitted back into the copper dome.

michael mott Posted April 26, 2017 Author #1338 Posted April 26, 2017 Hi Pat, the card is 14mm or 35/64, the card rotates very nicely. I printed it up on photo paper and then coated it with CA glue. The Plexiglas was very old I had it left over from my Architectural model building days so since 1984, the trick with removing the protective paper on old Plexiglas is to warm it up with a hot air gun. The paper then comes off as if it were a new sheet.

I'm good with that. I will shorten the hatch about 3 inches shorten the sidewalls length by 4 inches to make them 48 long and add a couple of round ports in them.

Hi Keith I have not had this problem in all the years I have worked with plex, perhaps it has something to do with the types of Plex, I prefer to use the Cell Cast type and not the extruded type. First I bored out a piece of 7/8ths with a half inch drill Then using a brand new tool bit which I ground from some 5/16 HSS steel, I was pleased that I was able to take a single depth of cut of .125" for a distance .312" which is the thicknes of the side walls of the cabin. The first three porthole shells still a lot of work to do but it feels good to make some progress.
