I got the same stuff, one size smaller bottle, last year. I hear it helps to cure water glass core sand too.
Andy, I forgot that you are working on a tail housing for a gearbox. You will probably have to do a combination of pattern shrink to get the...
Try for find some online info for 'pattern shrink' as it relates to foundry metals and beware of 'outliers' proposing excessive values. For the...
Very impressive, a different experience with the bound sand and raw lost foam versus something like Kelly would do with a coated pattern and loose...
Hard to say. I could see getting a set just to say that I have something designed and made by Burt and Henry, but I would not see myself (hobby...
I am also using a small Harbor Freight mixer with the internal paddle removed and a selection of various round rocks. Sometimes I wish it had one...

Koen, did you even figure this out or try it again? I wonder if the coating failed right at the end of the pour. There also seems to be quite a...

Drawing look good Andy, thanks. Did you develop the main round shapes (not the triangle gussets) as extruded sketches or a revolved surface? A...
@AndyOverPartsPro do you have a section and/or other views of the design so far? [ATTACH]
16 inches is not trivial to print, for most home systems that means sectioning and printing for days. What material are you looking to have cast?...
I get acceptable as-cast surface finish by coating the .16mm layer height PLA printed parts in epoxy ( bulk 2:1 or 4:1 with some working time,...
One and done would be ideal with lost foam, which can be cut by any number of tools including a coping saw to simple hot wire all the way up to...
