  1. The lego sorting is finished and the eye is Ok for some low dust workshop activities (I wore a pair of goggles just to be sure). Yesterday and today I recommenced work on the hull.

     

    The following three pictures show internal views of Cangarda.

    In the accommodation spaces the hull frames are hidden behind the internal cladding. I assume that space between the cladding and hull is full of insulation.  The only space where the framing is left exposed is in the engine room. 

     

    In the accommodation spaces I decided to use balsa to create the walls.

    This was installed in the fashion of barrel making - the balsa only being slightly thicker than the depth off the webs on the frames. An internal view might make this confusing remark clearer. The internal surfaces will be sanded flat and clad internally when Cangarda is removed from the building board.

    With the circular saw being out of action the cutting of the balsa was done with a razor saw.

     

    I was distracted from the balsa work when I realised I had mistakenly made the prop shaft casing 18mm diameter when it should have been 14mm. I started carving it back but decided I needed a guide, so I turned up the guide indicated by the white arrow.

    Positioning the guide in the casing allowed me to roughly carve the casing to approximately the correct size.

    I then shaped a sanding block to the correct external diameter and finished the resizing by sanding.

    It will probably take another week or so to finish the balsa work. The walls of the engine room will be devoid of the balsa filling.

    That's the problem with those sets - when we were kids, there were only blocks.

    Eberhard - Too true. There are now apparently 3764 different parts . I also remember in my day Lego came in red, white, green and black, today it comes in over 180 colours. I  think more is perhaps less in terms of child creativity. It must be a nightmare for the kids to find the parts they need.

    How the saw repair going Keith?

    Andy - I am still awaiting the CAP delivery from Amazon. It is not a problem because I had my second eye done a few days ago so I am banned from all dust making opportunities at the moment. I am busying myself sorting a huge pile of my kids lego back into its original sets for the benefit of my grandchildren. Presumably this is an exercise that will be repeated until the end of time. Chaos, order, chaos, order etc. etc.

  4. Brian - prompted by the above I should have been more explicit about the soldering. I solder with a variable temperature iron (typically set to its default setting of 320c) - although in the past I have used a fairly basic Weller single temperature soldering iron. I have never set fire to the jig - just some light charing at worst. I have never tried a torch for soldering brass wire of circa .050" or less diameter because I have found it unnecessary. I tend to solder with lead free solder wire of about 1/32" diameter. It is pre fluxed but just to be sure I always add a dab of plumbers soldering flux. This tends to work well for making guard rails.

    As for your offer to show me how to go with the brass method,

    Brian - I would tend to make a simple plywood jig for this type of operation as follows:-

    The slots in the plywood are most easily made with a slitting saw on a small table saw - e.g. Byrnes. If the top / middle rails and stanchions are of different diameters use different slot widths.

     

    Drilling holes at all the intersections provides clearance for access by the soldering iron tip. 

     

    The 1, 2, 3 sequence probably makes most sense as continuous runs of the top rail and stanchions will give the best visual effect. 

     

    The grid of slots accurately controls the position (uniformity) of the finished guard rail.

     

    I hope this makes sense? Let me know if it doesn't. Feel free to ignore it if you find a better solution.

  6. That is hell of an extensive update Brian - and all those laser cut pieces are making me jealous. As for the rails, is styrene going to be durable enough? Presumably if she is going into a case it will be OK. The dusting could be problematic if it is not being cased. I have a way of getting the brass option very regular if you are not wedded to the styrene option. Let me know if you are interested.

     

  7. Thank you Keith and Gary.

     

    I was going to have a productive day in the workshop but it was not to be. My somewhat recently neglected Byrnes saw decided I didn't love it any more so it threw a sulk and after a few hesitant attempts at starting it threw in the towel. If I manually kick over the blade it angrily bursts into life and bites my prodding stick. Ooch!

    I think I need to buy a new CAP (maybe a bowler). 

     

    At least I have learned summat (Yorkshire dialect). the 40/85/21 means that its operational range is -40c  to 85c and it will withstand 21 days at 95% relative humidity at - 40c.  

     

    P.S. Note to self  - remember not to lick the terminals - it may be less dead than it is pretending to be.
