Just realized my old sand ramming method was actually better for our small batch patterns.
For years at the Tacoma shop, everyone pushed for high pressure molding on everything. Said it was faster, denser, better. So I switched. But on our smaller, detailed gear patterns, the high pressure was causing too many crushed edges and bad draws. I went back to my old hand ramming method last Tuesday on a set of 12 bronze bushings. Took maybe 15 minutes longer total, but every single one stripped clean. No repair work. The slower, even pressure just works better for complex shapes under 50 pounds. Why did we all think newer always means better for every job? Anyone else still use low pressure methods for specific castings?

Newer tools are just Different tools, not Better tools.

Honestly, I got way faster results when I switched to the new version lol.

Hang on, so you're saying the new version @the_xena switched to isn't actually faster, just different? Feels like if it saves me 20 minutes a day, that's a pretty clear upgrade, not just a change.
