6 cylinder radial 'steam' engine

thingiverse

It seems like you're sharing a project update on a 3D printed steam engine design, specifically the R3-6C model. Here's a rewritten version of your text in a more formal and easy-to-read format: **Project Update: R3-6C Steam Engine Design** I'm excited to share my progress on this unique steam engine design, which utilizes additive manufacturing (3D printing) techniques. The design is an alternative to traditional subtractive machining methods, offering a more minimalist approach to mechanical design. **Design Features and Updates** The R3-6C steam engine features a radial geometry with orbital valves, eliminating the need for separate moving valves for each cylinder. This design simplifies the construction process and allows for easier assembly. * **Crank Spacer Parts**: I've added 4mm and 5mm crank spacer parts to help center the piston arms on the crank rod. * **Orbital Valve Update**: The Orbital_Valve part has been improved with a side cut that enhances airflow in the 12 o'clock position when the valve is closest to the inlet/outlet port on the steam chest. * **Crankshaft and Rod Master Updates**: I've updated the Crankshaft file to include holes for mounting Rod_Slave parts, and the Rod_Master file now features an integrated spacer on the return crank side. * **Piston Update**: The Piston part has been revised with narrower pin insert holes for 3.18mm brass tube (1.8") and deeper O-ring channels. **Test Results and Future Plans** The test unit functions well, but I've identified a slight clearance issue with the Rod_Slave file that requires adjustment. This can be fixed by applying a chamfer to the outer vertical edges of the 2-prong extensions that fit around the Rod_master crank shaft mounting disk. I'm planning to finalize the modeling and designing process within the next 10 days, as my Solidworks license is set to expire soon. I'll then switch to Fusion 360 for CAD design.
