Episode 5
It's crunch time at Sienci Labs, and Ben's taking a video time-out after this to prep for the launch (we're sad to see him go but he'll be back!) but in this final video he gets into rack wear testing: basically putting the 4x8 through the ringer and pushing the rack and pinions to their limits to test for durability, wear and tear. He dives deep into rack and pinion design so check it out.

Engineering the AltMill 4x8 Series
Ben, one of our mechanical engineers, is the lead on the upcoming AltMill 4x8. In a series of episodic #bts videos, he shows the step-by-step prototyping process leading up to its release. Throughout the series he will explain the engineering methodologies used and insights gathered that will ultimately shape the final design of the AltMill 4x8. You'll get an up close and personal, inside scoop of engineering shop life at Sienci Labs. The AltMill 4x8 is our most ambitious project yet, and is expected to go on pre-sale Oct 29, 2025.
