I run a coke fueled blacksmith forge. You need a decent starting fire and lots of air to get a coke fire to become self supporting. Coke doesn't...

"Gating and risering is by far the most controversial subject in the foundry and each expert comes up with his pet theory on the subject." - Not...
So similar to what Tops said, the gates are printed as separate pieces so you would put the runner in the drag, the vertical gates in the cheek,...
Version 1.2 is now available. Changes include: Select basin position to any of the four sides Set a back angle on the gates - Experimental...
I'm working on it with a few other enhancements.
The gates can be in the drag with the runner, or above the runner in the cheek or cope.
That's the intent but can be a bit hard to achieve in practice. One way is to have vertical gates like in OIF's video but at a cost of reduced...
This is where things are a bit counter intuitive. You actually want more surface area to increase the friction to slow down the flow of the...
Yes, they are risers and yes, I agree with you, they most likely won't work like that. In fact Campbell recommends against risers on the gates....
Looks good! But you've got the spin trap upside down - the conical part should be at the top with the vent attached. And it looks like the gates...
I've made a couple of changes to make it easier to print. The sprue and spin trap vent now have a flat side so that they can be printer on their...

Well, there's ya problem. An OpenSCAD version from 2015 is going to be missing a few features. It's under continuous development and the latest...
Whilst wandering the interwebs, I came across this thread on another site where Olfoundryman gives some advice based on his experience of making...
Latest is the eleventh edition published in 1998.
Yes, the spin trap is at the end of the runner to capture the initial shot of metal until the sprue and runner are full. The theory is that the...
I've been working in OpenSCAD (https://openscad.ord) - a code based CAD modeller - to produce a parametric filling system model. That is, you...
His Mini Casting Handbook is just as difficult to read but at least it has a lot fewer pages (and 1/10th the price tag). This book does however...
