    3. Preheat the bed, in my case to 70 deg C
    4. Giving the nozzle a few manual feeds beforehand to ensure it is all flowing well after soaking at 200 deg C.

    Loss of SW is a nuisance, but I thought you were on Fusion 360.
    KEN,
    Do you use masking tape?

    My little machine manages at between 210 deg C and 215 deg for the head and between 50 deg & 60 deg for the bed.
    Set the temps to what you require and it won't move till those temps are reached.

    I eventually found that easily the best thing for removing the tape adhesive still stuck to the bed (after trying everything else really) was a quick rub with good old cheap SALIVA then scrape it off with the edge of an ice cream stick etc - works a treat - If you can't find any of this cheap commodity in Aus, then I'll send you a bottle!

    FUSION 360 - it's fine and I was learning it well, however, after a year of getting you hooked ...... "WHAMMO!" - it becomes too bloody dear for a person of my means! - very good for those with a business I guess!

    SW - Same thing, too expensive for a dabbler like me - but again it's very good, as we all know!

    DESIGNSPARK MECHANICAL(DSM) I'm using this at the moment - this seems to be an older (and free) version of the more sophisticated "SpaceClaim" but it's fine for me.

    FREECAD, free as it's name implies, this is 'open source' - seems fine, but I still have to check it out properly.

    There are others as well!

    …… all great fun for an old guy! If only all this had been around when I was just starting out!

    Will as far as i can see you just re-sign up again for free according to this
    Yes. Fusion 360 will always be free for hobbyists, makers, startups working on developing their products, and students/faculty. Hobbyists get 1 year free to start, whereas students and faculty get 3 years. After the subscription expires, you'll have the option to renew and start the free subscription all over again

    Will,

    Did buy some tape, from yer old mates at Bunnings, it was 50 mm wide, blue and made by 3M, mfg in the US of A. Haven't used it yet though.

    Yep, re-enrol with Fusion 360, you are a hobbyist. As it's internet based, I'm sure they could see the turnover of your usage, and the nature of your work, so you wouldn't have any issues. Unless, of course, you were designing the full engine and body model of next year's Lamborghini.

    Thanks Husa, / Lohring
    Looks like I was too hasty about Fusion 360! (too busy using it to really take notice of what was actually being said), so I might just carry on with it - once you know how to use one then the others will naturally be much easier to learn and each one will have its own particular strong points. - I'm doing fine with the present one (DSM) of course but then, it is possible to learn them all!

    Ken,
    Yes, saw the blue masking tape there as well, just went for the SCOTCH one because that's what worked originally and as saliva (for removing the glue) works well with it, it's free and I have a plentiful supply of it (always dribbling on ), but who knows though, the glue might not work well at different temperatures!

    Yes, I would be a little more worried about them having a good laugh at my attempts at drawing than anything else! - the possibility of them copying my inventions definitely doesn't worry me!

    the crucibal trolly, not finished yet as it needs a ring to hold the crucible so it can be transported and tipped. Note the highly sophisticated lift / lower system.

    Looks well thought out and quite a beast it would seem ! - will you still be using the old faithful oil / methanol / whatever? burner or will there be an upgrade of that too?

    All well and good but that is just a toy foundry, my lid weighs 90 kg and the crucible I'm useing is too heavy to lift with just one person. So the necessity to need a crane. Having a crane already there, may as well use it to lift the lid also. I might be full of shit but let's see how it works in real life.
    This setup is a copy of the foundry I used to use in Thames. What I considered a 'proper foundry'.

    Will D, yes I'm useing the same burner, fuel and vacuum cleaner as it all worked well with this size pot on the last furnace. Thankfully I made the burner hole big enough to fit a bigger tube if this one is inadequate.

    90 KG what scale is that?
    I never realised it was that big.ALthough i did wonder when i seen how many bags of castable refactory you had.
    what size is the crucible?

    Yes, definitely a beast! all much bigger than the' Myford Boy' one above ........ on a higher plane than anything I would dare to try!
    I am also a great believer in the "suck it and see" method (using educated guesses and commonsense). best way to learn really!
    I went to pick up my furnace etc a while ago from Puke, but the bloody burner has gone missing - and it was so good too!
    The plans for it are buried somewhere in the archives of my mind - unfortunately the archives are lost too!

    Nilfisk who i think brought tellus used to be part of the company that made Nimbus motorbikes
    I think Nimbus had one of the first Telescopic forks plus a few other stuff years ahead of their time.

    Wasn't it a Swedish inline 4 (fore & aft)?
