Gear layout design.

One year of progress. Had to learn some new techniques. When all continues to go so well, this engine will run in 1.5 to 2 years from now.

Xander,

You've accomplished a lot in a year. You've definitely captured the style of the engine you are modeling. It looks nice.

I'm indeed aiming to get as close as possible to the look of the real one.

In the design I try to use the same approach of the building blocks such to have functional bolt and studs in the correct places.

Once it is a running engine I will add more "fake" details e.g. mimic all the remaining nuts, bolts, oil lines etc of the real one.

I found a very nice YouTube movie on how to create a con-rod with a cast appearance build from bar stock.

Based on that I made the following work flow picture:

Main bearing plates pre-machined in a package, now mounted for line boring to bring to size and improve concentricity.

Had to stop the cnc program after each pass to remove a birdsnest. Playing with feed, speed and depth of cut did not result in chip breaking.

Soft and tough material, but nice surface finish.

Preparing and dry fit for line boring.

Have to add more clamps for stability.

Crankshaft bearings, crankshaft, camshaft (still without cams) and gears are in and running smooth. Again a main hurdle towards a running engine taken.

Ziet er netjes uit.....

All bronze bushings ans clips in place.

Almost a pitty that all of this will become invisible in the final engine.

Status today. Note, all temporary slit-screws and hex screws will be replaced later by studs and nuts.

Since it is now becoming relative (top) heavy and all the hours invested, I took some time to build a temporary stand for the engine. This to avoid damage during build, transport and exhibition at shows. On the base is a photo that I found in a brochure of this engine.

Once the engine is completely finished, the wooden frame between the engine and the wooden plate will be replaced by a steel one to avoid issues if the wooden plate ever slightly twists due to changes in humidity/temperature. The frame can only be designed once I know how to connect the generator and whether or not I need an auxiliary bearing on the flywheel. Such aux. bearing was relatively common on these engines to reduce stresses on crankshaft by the heavy flywheel. Hence the crankshaft will remain excessively long till that is decided. I rather cut twice than cut too much off.

Also added the tapered bushing to connect the flywheel with the crank shaft. The M4 studs go through M5 threaded holes in the bushing into M4 holes in the flywheel. This allows to pull the bushing out of the flywheel by removing the M4 studs and threading M5 screws into the bushing. These larger screws will not thread into the M4 holes in the flywheel and hence push the bushing out.
