The Bucket Foundry

[Gradella23]

Hello everyone,
I received a nice little gift from Voxeljet at the office today

Nice, I'm pretty sure on facebook i saw Ian Harrison of Viper Racing use that technique of joining the water core to the rest of the printed cores as well.
Not sure if just for prototype cylinders or production.
Is there enough room to fit a cooling channel between the transfer and the bore?
How much did they cost if you don't mind me asking?

i paid 85€ excl. vat, but the same core would cost 19€+vat if i buy 10 of them and 25€ if i buy 5.
Obviusly the size plays a major role here, this part is 130x105x87mm.

the cooling channel on the inside of the transfer will be the next improvement for sure, i was only afraid about some cracking cause the biggest channel i can fit there is barely 5mm thick.
the next time i'll try that, i already have the updated model, and i'd also like to try a bridged exhaust.
but first of all i need to have the prototype casted.

Anyone know where I can buy some green casting sand in Wellington?

Where is your nearest foundry? Fielding?

Yes, Feilding or Palmy, but I was hoping to save a four hour trip. Must be someone in Welly?

I can make some yellow sand. Might smell a bit when heated up.

I remember going to a foundry next to JJF when I was visiting them. Back in Seaview. Long gone by now. Erm, Neeles rings a vauge bell.

Here's a pretty cool process...with old mate "2 stroke Stuffing"

Looks like an ExOne sand printer is beyond the budget for a tinkerer. Neil, you could use one...

Not sure if these youtube video's concerning casting for Kreidler already passed here on the thread ?
