    Its all well and good, the engine is running nice,
    BUT at some point it will stop again. Its always on my mind when Im flying, looking to where I might land, when it all goes quiet. Cant tell if Im excited, or frightened, either way its exhilarating. Engine manual says 'should only be operated over flat ground'.

    Perhaps.
    There will be a small chainsaw pull start attached outside this flywheel.

    Amongst other things, been progressing casting something from a 3D printed part. In this case it is a short inlet manifold runner for a Nissan VH45 V8, a foul stroke it seems.

    So, printed the part using Polycast filament, a bit wax like. Then stuck on a couple of moulded wax bits for the ingate and riser and then invested it in a 2:1 (by volume) mix if Plaster of Paree and sand.

    Then slowly heated it to successive melt out and then burn out the filament, the last step was overnight at 400 C. Lots of nice noxious smoke and smells. Made up an insulated burnout chamber, based on a 240 V hotplate element, controlled using an old thermocouple controller, not programmable though.

    Letting it cool to room temp (didn’t do this the first time and went in hot…fail) and splashed in some melted down BMW rims.

    Came out pretty well, some flaws when the plaster mould split, I think at the time of pouring as it wasn’t split before.

    Pics tell the story.

    Nothing much really - clearing out my garage completely - preparing to move out in the near future! no more bike stuff etc ( too many other things to think about at the moment!).
    BTW I found that Facebook is bloody ridiculous (have tried it and have more or less rejected it!). - this is good and so I'll keep looking in now and then - good luck with the new bike - have fun with it before you (have to) convert it to electric!

    Looks fine Ken - definitely getting there with the 3D printing/casting - I look in sometimes and have just spotted your post! ....... BTW where can I check out "Polycast" filament - does the filament break easily? - where did you buy it? - I would like to give it a try sometime (ie if I can find the time ........ and my foundry gear!! - I was going to give up, but then thought, you only get one shot, so why not - I don't want to miss out!
