Mechanical excellence through design & engineering. Carefully crafted form & function. Prototype to production.

We haven't even discussed modular hydraulic connectors yet. Just look at this beautiful setup. You'd have to be crazy to not want to use this.

Look at how cool the action is on this Sykes herringbone generator. This design allows you to cut teeth down to a sharp vee (though this part has a central groove). All of these machines use a 30° helix angle on the guide. My father used to run these back in the day, cutting gears up to 65" in diameter. From Themobilegearhead on yt:

The "butterfly" flexure pivot: No moving parts. No friction. No lubrication. No wear. No backlash. High precision. High radial, axial, & transverse angular stiffness. Compatible with zero-Gs & the vacuum of space. Made out of a block of titanium via wire EDM. More than 1.4 million cycles of ± 7.5° stroke without failure. Designed at CSEM by Henein and Spanoudakis. Video footage from Christophe Yamahata.

Trying to figure out the best way to make a part like this... > metal > thin wall > flat bottom > relatively deep hole > depth must be held tightly The top version is the simplified form, bottom version is closer to ideal. Bore as shown is 1/4" with 2" OAL. Running through different possibilities in my head on how to make it one piece or multi-piece. Ideally constructed out of stainless or titanium. It can have a hole in the end, but must still have some sort of step / lip for retaining purposes. Don't want to weld. Doesn't have to be super cheap. Under 1000 pieces per year right now. Need a nice finish. In actual production the length could increase to 4". Any thoughts?

I've been obsessed with motion amplified videos lately. By utilizing high definition video & image processing, the tiniest of movements are amplified into clearly seen real-time motion. Clips from RDI Technologies & RMS Ltd. dynamically demonstrate what these systems are capable of. Potential problems become highlighted, with the software able to overlay force vectors & provide analysis, and also filter for specific frequencies to view resonance. The invisible, visible. I need to try this out for myself...

For anyone curious how flat face couplings work (and how air entering the system is kept to an absolute minimum), this animation from Stauff provides a great overview of the operating principle:

"...a small group of scientists here has been investigating a strange new space-age metal, a nickel titanium alloy called Nitinol..." "...the Department of Energy invited the people of McDonnell-Douglas to investigate the potential for Nitinol heat engines & Nitinol power plants." Fascinating stuff. "...no one knows exactly why this machine is working because no one knows exactly why Nitinol behaves the way it does." Originally produced & aired by CNN in the 70s. Posted by Kevin Sanders on yt.

Unless you're into bikes you may not have seen this style of belt before. This is a Gates Carbon Drive. It uses a central channel in the belt to keep it centered on the sprockets. The belt itself is reinforced with carbon fiber strands & strong enough to replace a chain. No maintenance, no noise, no lubrication necessary. There's a very slight hit in efficiency compared to a clean, fresh chain, but once dirt & higher power enter the picture, they prove superior in this regard. Gates offers many different sprocket designs & sizes for different applications, which is a good thing because they are not easy to machine compared to standard timing pulleys. I tried to make an off-the-shelf design work in this project, but sometimes you just have to go full custom, and that's exactly what I've done here. Can't wait to share more details of what this is when we get further along... Anyway, if you have an application that you're considering using a chain or timing belt and need a low profile setup, be sure to give this system a look over. It has many positives in its favor.

I wonder how the first person figured this process out? > grab a part that's loaded with sharp burrs > stick it in a chamber filled with gas > ignite that puppy > boom > your entire part is smoothly & accurately deburred, inside & out. Thermal deburring (also known as TEM, or explosive deburring) folks. Yet another method of making stuff smooth. I have to try it. (video clips by Extrude Hone)

I'm an engine fan. And a 2-stroke fan. And a crossplane V8 fan. I've always wondered what a 2-stroke crossplane V8 engine might sound like. If it's anything like this model created in the Engine Simulator (which is pretty accurate), I am so in. (video footage from Noffie @ yt)

Stumbling upon a novel idea, even if it's not exactly new, is always exciting. Came across this virtual rolling contact joint when researching spherical rolling joints. Created by IRIM LAB KOREATECH & genius in its simplicity, this joint consists of three pivoting linkages that allows for 2 DOF in roll & pitch. They then integrated it into a robotic arm, complete with a driveshaft passing through the center. Has anyone ever used one of these designs in practice?

A classic ode to mechanical principles. I've been an engineer for 20 years, have watched this video multiple times, & still draw inspiration from it with each viewing. I never seem to tire of elliptical & irregular gears. If you've haven't seen this, enjoy Ralph Steiner, 1930

On the complete opposite end of things... If you have plastic or rubber parts, you can use liquid nitrogen or dry ice to freeze the burrs & flashing, then tumble or blast them away. All other surfaces are left pristine & clean. Cryogenic deburring. So cool. (video clips from Cold Jet Australia Pty)

V7? Inline 9? V11? Inline 23?? So many wild engine combos out there you never see (or hear). I rounded up some interesting (& potentially possible) inline & vee simulations in this vid. There are far crazier ones posted on yt, including rotaries, X, T, & H configurations, etc etc... (video clips from IceManV93 on yt)
