Mill Engine Cylinder Casting - doubleboost - 08-12-2012

Hi
Lads
I made use of the sand cores i made last week and cast my cylinder
[Image: IMG_4071.jpg]

This picture shows the sand core in the mould

The small round bit is where the metal is poured in (sprue) the rectangulsr bit is the riser
This feeds the casting as it cools
[Image: IMG_4077.jpg]

This shows where the riser has been cut off (nice clean solid metal)
This is always a welcome sight

Very happy with it

I cast this yesterday with poor results

Nasty void in the riser (scrap casting)
At least you can always cut it up and re melt it

I could not resist machining at least one face
Good clean metal

John,
Excellent job mate

I'm glad you explained the difference between the sprue and the riser Thumbsup

'cause I'd be temped to pour the metal in the "big hole" Slaphead

Any idea why it looks "silvery" on the outside?

Great bit of casting, don't suppose you did a video Smiley-dancenana

Incredible. Not something you find going on in most back yards these days. Very impressive John.

What's next? Mining your own ore as well? Don't start slacking now! Big Grin

Nice work John. It's been a long time since I've had the fun of machining a casting.

I assume by the blackening around the casting, that you use an oil tempered sand? Is it your own recipe or do you buy it already mulled. And what about flux? I know chlorine type degassers are used for aluminum, but do you also use some sort of flux for the bronze?
