When I am unsure if a pattern will pull cleanly from the sand, I make a sand mould in CAD, subtract the pattern from it, and then see if...

That flywheel is better than any 3D print I've produced, including resin.

Interesting comment about a CNC gantry router, what software would you use with that? Those wooden patterns are great!

I read somewhere that the FORD logo Henry Ford used on his cars wasn't his signature, but a commercially available font. Perhaps the...

In the early days of my casting attempts, I used to harden my sodium silicate cores with bicarb and vinegar in a container that kept the...

The photo shows one of my compost bins in front of my gazebo. It had been blown there by the recent high winds from 40 feet away. It...

My main mistake (fault) is lack of patience. When I made a core, either by using sodium silicate and sand, or epoxy resin and sand, I...

Reading this thread makes me realise how many mistakes I made when making cores. Many thanks.

Good luck!

I have a Dremel 225 flexible drive. I have no idea if it is the same though.

I had trouble getting draft on a logo once (once?!) so I extruded it onto the surface with no draft, 3D printed it and used Milliput...

I forgot one very important step in my description of creating a logo. Inkscape. I would use your photo, crop it, convert to black and...

I would be tempted to make the Monitor logo part of the 3D print. I have done this with software as simple as Designspark Mechanical...

A very interesting video. If I build a bigger furnace to melt iron I will use your design. I can buy the brand of oil bound sand here in...

Thanks GreenTwin. I will design and 3D print a split core box that holds about 100g of sand and start the experiment. I can't get too...
