The Home Machinist!

I am not even sure of the right terms here, but was wondering how much bigger my pattern has to be for casing ZA8?
I have heard somewhere 2% bigger to handle shrinkage during the casting process, but I can't find that number anywhere now.
Has anybody experience with ZA8?
Thank you,
Mike

The board will be down a bit for some maintenance, tomorrow morning. (Friday, March 5th)
I do not expect it will be down too long, perhaps 20 minutes maximum.

Right at this moment, I would truly appreciate a bit of help to keep the website going. We are not at risk of imminent shutdown, but it would sure be a help if anybody is interested. Money can be mailed to my consulting business at: EDI Enterprises, Inc. PO Box 1059 CHANHASSEN, MN 55317 Or paypal to...

Didn't the last Kozo build series in Live Steam Magazine have a built up cylinder block?

If you weed through here:

On page 67 or so is the article: Fabricated Cylinders by " L.B.S.C."
Which might also be of help.

The board maintenance is coming!!
There are a couple things I need to get taken care of first.

This is a fairly large upgrade, so it may be down a while.
Thank you for your understanding.
