    Maudslay Brass Steam Engine Drawings

    Many thanks to John Mcclelland for producing these detail drawings of my Maudslay steam engine. He took the initiative to forge ahead using just pictures and a scattering of support files. Other than answering a few questions, very little help was required from me. Thanks again, John, for the...

    Health Update

    I know I don't visit this forum very often, but a lot of you are familiar with stuff I've done and contributed in the past. I consider all of you friends and thought it perhaps relevant to let you know what's going on in my life. Not looking for sympathy or even condolences, just providing...

    Maudslay Model Double Acting Oscillating Steam Engine

    I'm learning how to create drawings in Fusion 360, so thought I would start posting drawings of the Maudslay model steam engine I just finished. The first part I made was the cylinder, so I thought I would start with a drawing for that. Let me know if I've missed something or am doing...

    Maudslay Model oscillating steam engine

    Here's a video of my completed Maudslay oscillating steam engine. Lapping the rotary valve to valve block took fixed the last of the air leaks, so now the exhaust is about the only air that is audible. Chuck

    Lapping Brass

    I'm building a small, double acting steam engine modeled after a design by Henry Maudslay. The engine uses a 3/8" diameter, 5/8" long stainless steel rotary valve which rotates inside a brass valve block. To reduce air leakage, I am trying to lap the valve bore in the brass valve block and...

    Solenoid powered steam engine

    This small engine is designed after a horizontal mill-style steam engine. It's powered by two, hand-wound magnetic coils driving a piston assembled from 3 or 4 neodymium magnets. https://youtu.be/oJf7N7hsLk4 The coils are attached to an Arduino micro controller with a motor shield. The...

    iDesign - It's not Autocad, but it ain't bad!

    As you might have figured out from the name, iDesign runs on an IPAD. Now, before you turn up your nose and and stop reading, I felt the same way after reviewing a number if CAD apps for the IPAD in the past. But this one is a serious contender for 2D CAD. It has a rich set of tools including...

    Lathe Turning Head for CNC mill

    I've been toying with the idea of making a small, special-purpose CNC lathe, then today I ran across this... https://www.youtube.com/watch?v=9Sr9p8tCv_g This seems like an altogether better option and maybe not to hard to make??? Chuck

    Horizontal IC Engine 5/8" Bore

    About time to get started on another engine. This will the smallest IC engine I've attempted with a 5/8" bore and 1.25" stroke. I want this to be another slow running engine and I think this is about as small as I can go without it sounding like a weed whacker. Didn't have a beer can...

    Model Engine Generator

    I'm taking Rustkolector's advice and adding a generator to my vertical single engine. I spent the day today working on a small generator. I started with a small DC motor and a 2.5" x 2.5" x 1.5" block of aluminum. I bored the center hole in my lathe, then whittled away the outside on my CNC...

    Model Engine Carburetion & Fuel Systems

    The past couple of days I've been experimenting with carburetion on my vertical single 4 stroke. In this video I've mounted the carburetor on the fuel tank and connected it to the engine with a relative thick urethane tube. https://www.youtube.com/watch?v=C8AYDaoRpHU I've discovered...

    Simple CNC flywheel milling

    Here's a video of a simple technique for cutting the spokes in a flywheel. I developed the G-Code to cut the pattern for one space between spokes. After making one pass for one space, the g-code stops and I manually rotate the rotary table 1/6th turn. Then I run the g-code again to make one...

    Oilfield Engine (Was Bessemer...)

    I'm back to work on my (used to be Bessemer) Oilfield engine. Since I'm converting it to 4 stroke operation, I guess it will just be a generic oilfield engine. I'm retaining the frame, flywheel and crankshaft, but the rest of it will be new. I want it to have a sideshaft operated cam and I've...

    Monster 4th Axis

    This is a (much) larger 4th Axis I've started putting together. I already had the parts on hand so thought I'd see what I could do. The stepper is a NEMA 34, 1600 Oz In rated at 3.5 amps. It won't go very fast, but it does have some fearsome torque...
