I'll bet you're glad you drilled the bars just behind the "heads" of the "hammers", if they were solid the shop elves would have taken off the hinges on the spirit locker doors in one hit! (did I just hear "let the games begin!" in a loud elf voice)

This occasional eccentric says your new Diesbar eccentrics look great Chris. 

 


They did spend an hour trying to use those holes as bottle openers...       Hmm, what to use as an elf distracter tomorrow?   Oh, wait, make them build parts!   

Thanks Michael!

This afternoon I got a little more playtime in the shop, and drilled/tapped the rods for the eccentric strap arms. One end was screwed to the middle hole of the short bars I made earlier, which are the flanges to attach to the straps. Here one of the elves is holding one of them up prior to getting them silver soldered.

Then I had to make another whole set after the elves got all excited, yelling something about finally breaking into Captain Jack Sparrow's treasure chest with their new sledge hammers, and ran off with the first set.   

Then got them silver soldered, they are soaking in the pickle solution now to clean them up. Once clean, I can grind off the screw heads, and run in a length of 4-40 screw into the other end of the rods, where they will screw into the release fittings at the lower ends. I think I've figured out the steps to make the release fittings, as shown in the picture the other day. The main blocks will be milled out of a single piece, with a section milled out for the thin lever. A second thin piece will rivet back on over the recess to close it up again. Easier that way then trying to mill a really thin deep slot in the blocks. Or, so the current theory goes! Will find out over the next couple days.

Chugging away nicely Graham.
So the flame is pulled into the cylinder through the hole? If so, why do you think that the material choice would have any effect on the running?

That’s the thousand dollar question Dave! But after trying many different materials, and I’m not exaggerating, this is the first time she’s run like this on propane. I took the engine to the Anson engine museum many years ago and used their supply of Hydrogen that they use for the carrier flame engines, she went like a rocket! Period advertisements suggest a running speed of 500+ RPM. 
Currently the RPM seen in the attached video is about the maximum she will do, I’m assuming it’s the much slower propagation speed of the gas used against the original fuel?

HOT AIR ENGINES, ICE’s ? God forbid….

Looks  very cool, I like the set up with the little gas torch. It seems very happy chugging away and makes a great sound! 

The gas torch fixture, if you can call it that 😂 was used to steady the flame at the correct position. Mr Hand was just a little too unsteady for the job. I have ordered a couple more torches from eBay so that a custom made bracket can be fitted, similar to the original design.

Watch this space for future developments.

Seen in the Netherlands a couple of years ago. A beautifully preserved, and original condition BEECo

Addendum…. The photo is in fact the largest Schoner engine the 154/2
