The Bucket Foundry

[F5 Dave]

Thanks for taking the time to show us this.

Yeah, cool vid's too.
I was asking myself, what is the Magnesium for when it told me!

Flettner thanks for explaining the sand casting process!

Please post more pictures of your projects when you do this kind of stuff again.

[Flettner]

We are all just lucky Dave ( GerbilGronk ) has a video camera and takes the time to record this stuff.
I just want the end product!

Neil, you might want to point out to Dave he is signed in a a Blokess?

[Flettner]

Ha Ha so her is.

My balls have just dropped. Once I retrieved them from the old girls handbag.

Hi Will, if you want to capture a youTube video you can use download helper, its a plugin for firefox

YOW LING,
Thanks for the link, I have downloaded the Tubal Cain foundry tutorials from You Tube.
It was no problem at all to add the plugin to Firefox, so I will now have them on hand and easily locatable till I don't need them anymore. Now checking out Foseco for a suitale crucible.
Some people are telling me not to use an iron or steel pot for aluminium, but I see that some people do that and apparently have no problem with iron contamination??

FLETTNER.
Good video, - I'm impressed with the casting, of course you are way ahead in this scene and with the machining equipment.
However, I now have the bones of a home machine shop and of course plenty of time to try and catch up with you, (yeah right).
I'll probably just stick to model size engine experiments to begin with.

Dunno what happened to my balls, I had forgotten all about them!

Cheers,
Will.

YOW LING,

Some people use flower pots........(i am not implying you should btw)
with the iron i depends if you want to use them for a structural purpose whether you would be worried about the contamination or not

[Flettner]

No problem with a steel pot so long as you coat it first. There are some foundry ( ceramics I think ) that are spray on able that will stop the iron dissolving into the alloy, But a proper crucible is best in the lomg run.

Crucible

FLETTNER, PLUMBA.

I think that the crucible on Trade Me is much too big, I will need something a little smaller and lighter. Also I have been told that it is not good to use graphite crucibles with ally. (silicon carbide ok. maybe?)
I'll try Pyrotek (just down the road) next week for supplies, also hopefully I can also get some helpful tips from them too. - Foseco is a lot further away, although they sounded as though they might be helpful too over the phone.

Will.

flettner, do you think lost foam technique would be usable for casting prototype cylinders? Those foam patterns could be cut with cnc, its not good for mass production, but maybe one offs?

I'm glad you asked that, I've been thinking about the same thing; and packing up the voids and hoping it all works???

Looking forward to hearing Flettners opinion..

[Flettner]

Maybe? I haven't had a lot to do with foam type patterns. I would think if you have the solid model and a CNC you would just cut the core boxes straight out ( of steel ). The main pattern would also just be cut from ( what ever material you want ) soild without the build up process like I do.

Funny thing is, I have solid model design program and a CNC yet I still build my cylinders like I've shown here. The reason I did it this way on this forum is to show that you don't need all that fancy stuff to build a good useable cylinder ( also with ability for limited production ).
Plastic beads, hot glue and bondi. Low tec and available everywhere.
