Re: So I built a hydraulic pump today
Volume doesn't scale same as distance
1/14th scale, 14 feet would be 1 foot, but 14 cubic feet would be .0051 cubic feet
So your scale weight example would be 57.14 lbs in 14th scale

Re: Drill and tapping Chrome parts
You can also get oversize taps to account for the chrome plate thickness. Something like a H7 or so. Talk to your plater about that and they should be able to suggest the right size for you.

Re: 3D printing KH Body Attempt
