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...
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...
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...
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.

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...
For what it's worth, I have subscribed to a paid account with PhotoBucket so pictures I've posted on all my previous build threads should now be visible. If anyone has problems seeing any of the pictures, please me know so I can take it up with PhotoBucket.
Thx...

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.

The coils are attached to an Arduino micro controller with a motor shield. The...

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...

I've been toying with the idea of making a small, special-purpose CNC lathe, then today I ran across this...

This seems like an altogether better option and maybe not to hard to make???

retty self explanatory. I quick and dirty way to grind flats on a socket head cap screw turning it into a hex head bolt. No special equipment required, just a small machinist vice, an Allen wrench and a belt grinder or bench grinder with a suitable tool rest...
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...
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...
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.

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...
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...
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...
Waiting on parts before I can continue on my outstanding projects, so what do I do??? I ordered some more parts for yet another project!
