Since patterns are the common starting point of most sand castings, I thought it may be beneficial to provide a link to a build log that describes the methods I used for making the patterns to cast my
Model Engine for LMS 1831 (AKA Wallaby) (http://www.modelenginemaker.com/index.php/topic,930.0.html)
A 2 Cylinder 30cc petrol IC engine designed by Edgar Westbury in the 1940s
I hope you enjoy

Those are nice patterns Bez. One thing I need practice at. I do want to start one day, but I have myself spread thin now. Once I decid to retire I my have more time. Right now time is limited.

Thanks Don
I had a lot of fun making them.
Its a real buzz seeing a little working donk reving away from castings made in the back yard, thats for sure. :cheers:

Very nice set of patterns :ThumbsUp:. I see that they have been nicely rounded, smoothed and varnished (?), very necessary to stop the sand sticking. In my experience (I have only cast once :embarassed:) a well finished pattern helps discourage flashing on the casting.

Don when you retire you will have even less time than you have now :lolb: Ask anyone who has retired how big the list becomes

Yea Pete, my buddy Jim has been retired for years and has less time now then before. So I get what you mean.

Hi Bez,
Nice to see projects where constructors are using their own castings, I have found it much more rewarding. Have just made the patterns for a beam engine and am waiting for a nice sunny day to do some casting.
Cheers David

Well :hi: to the forum David.
I'd like to see your beam engine, are you going to publish a build log?
