Better listen carefully. I see the "Why did you that in that way, while I told you otherwise?" in his eyes. And they are always right.

No, no, you've got it wrong - he/she is saying WTF is this thing doing on my pozzie?? - was it done on a 3D printer? - If it wasn't done on a 3D printer then it won't work!

Don't be fooled by that 'butter wouldn't melt in it's mouth' look, Miss Sparkles (Don't ask) would just as soon rip your face off! She says fill my food bowl, so like a good servant, I do.

Last I saw of him he was in China and posting slightly raunchy videos of his girlfriend. Noone is betting on him not being in jail.

totally escaped jail

Hi John, good to see you here.

Meteor sent us a couple of vids you might find interesting:

Wonder if this stuff would be of any use for our purposes?

Is anyone selling the blue stuff out here?

Great video's on making pistons. I seem to recall seeing some outfit near Perth that was very high tech in their casting approach.

Maplins used to sell something very similar to this. It went hard when cool, so I don't know if it would be possible to use it in the same way as vinamold. I never tried the stuff but seem to remember it goes like putty when hot and may not be pourable. That blue stuff could well turn liquid enough to be of use.

It appears to have the same texture when cooled as the stuff used by the dental people to take a pattern of people's gums etc. for false teeth - (could even be the same stuff or similar)
I did manage to cadge some of the dental stuff recently and am waiting for an opportunity to use it - it's got to be good!
Seems it is made from some sort of seaweed and is non toxic .... and I got it free!
However it is in powder form and is mixed with water initally to set it going, so I guess there is a difference there!

[EssexNick]

Having false teeth myself, I know the stuff you mean. At the time I was fitted for them I did ask about that stuff. My dentist said something about it having a limited life after it had been mixed. Probably because it's organic. I didn't pursue this any further as casting is really a bit of a pipe dream for me. It could well be a very useful thing to use, but not for something that repeatedly gets put to one side for weeks on end. Please let us know how you get on.

Argh, finally got the new furnace up and running, cast three new 360 gyro cylinders with the thicker power valve boss. These have been moulded in sand for over a month now so.way past time to cast.
I've changed the metal inlet port.to the mold, it's smaller so fills the cavity slower. Less turbulence in the metal as it fills, no bubbling at all now, slow smooth fill. Learn as we go, just not too slow or you will.end up with a short.
Got forced into a corner, this bloody caravan I bought (classic 70's) has ended up one of the wife's favorite things so now the bloody weekends are spent not in my workshop.
I'm using the caravan time to learn my three D drawing programs so I guess not all bad.

Think you're talking about alginate, widely used for arts and crafts moulding. Hobby shops sell it in the UK.

I ordered some of that blue stuff anyway ( just to check it out) - The soft Vinamold I have is the brown jelly like stuff and probably needs to be harder. I think this blue stuff may not be rubbery enough though, but worth a try I guess (not too expensive) and doesn't need to be heated much. - but let's see how it goes.

Yes the perfect setting for learning 3D - nothing to get sidetracked on and looking at the view gets a bit tedious after a while!
Guess you'll need a good heater these days!

[Flettner]

Yes it has a good heater, thankfully. I bought the caravan spur of the moment thing, for use at the Aria two day trail ride (sick of putting up the tent in the dark) but now we are using it for just getting away on the weekend. It's old school with 70's styling, orange and brown wood grain interior. love it!
Just cleaned the sand out of the three cylinder castings, all appears sound.
