Bubble Sextant Mk IX, Bubble and other Repairs (14)

Description: Has your Hughes Mark IX, IXA, IXB, AM or BM Bubble Sextant got an uncontrollable or non existent bubble? Many seem to have a problem, the seller usually claims not to not know how to make one so can't help. Been there! Ever wondered what the fluid is and how to re fill the bubble chamber? Well, I did, and spent a considerable amount of time hunting round for the information which seems to be sparse, incomplete or, as I eventually realised, even plain wrong. I have been able to discover the correct fluid for re filling and have found an easily available substitute. Having downloaded Bill Morris's excellent book from https://sextantbook.com/ I decided a simpler approach was needed by me. Having stripped down several of my own bubble chambers using no special tools I made up some jigs and tools to ease the job. The operation is not as difficult as it at first appears and should be within the capability of anyone with reasonable manual skills and simple tools. Another major problem with most of the available instruments is the stiffening of the index and other bearings. Having repaired a sextant you need to check calibration and then set up the scales.I have covered that point from several angles. I describe my method for freeing and lubricating the main bearings along with any other things I have come across whilst working on these superb instruments. I have assembled all my findings regarding bubble and other repairs into a booklet and added photographs and drawings to illustrate the various features and operations. I decided to check various suitable fluids for viscosity and refractive index and have added my results as well as an electrical diagram for all models with simple, but accurate, methods for checking sextant calibration. Having made some simple mounting fixtures I have given drawings to enable you to quickly make some with scrap wood. Any tools or jigs are complete with dimensions to enable self manufacture. These are all methods I have tried and found to work successfully. What you get for your money are 36 Pages with 28 illustrations in A5 format, Black and White. I usually have a number of new rubber eye guards and lamps available Take a look at www.g4osj.co.uk for more information.Postage (UK) £2.00* * * If you have bought one of these booklets in the past there have been some addendums which I will happily supply for the cost of a first class stamp.
