Well I got the engine to a state of putting air to it and see if it would run.

It ran a couple of times then gave up. I fiddled with it some and got it running again. It slowly came to a stop. Found out the shaft that the flywheel is on was a bit tight. So a bit of polishing loosened it and it ran again and then came to a slow stop. Flywheel was still free but the engine just wouldn't run again. I fiddled with it for about 2 hours and still no go.

So I either have to build another or tinker some more with it. I decided I'd shelf it for now and build some tooling. Glad I didn't get around to makeing that fancy base I had planned.

Bernd,
I had exactly the same problems, getting my set of parts to run!  :scratch:

I had purposely made just sufficient bits to make a runner.

Never having made an engine before I wanted an early boost, to actually finish the build.  ::)

Remembering Stew`s early struggles, I turned it all ways around, on the end of the airline.

A shot of WD40, & it chuffed slowly into life as it hung upside down.......  :D

This is it, after some 10mins running.......



Hang in there!

Nicly done chaps.

 :clap: :clap:

I've lost count just how many of these little beasts have been made now.

Can we ask, has the virus now peaked? :- or are there still a few more out there waiting to be revealed.  :proj:

 :mmr:

Have fun out there

Bernd, you saw how mine didn't want to start when the air pressure was up too high?  Start it at less than 5 PSI, and then crank it up to about 20.  Once it's going, you can make it scream, but starting on high doesn't seem to work.

It likes to be loose, and will have problems if anything is too tight.  So, spray it with your favorite lube, and run it at high speed for a few minutes, then clean it all off, and it will tick over slowly.  Mine would barely run at first.  Now, after running for an hour or so, I can get it to go on lung power.

Roger,

The engine is pretty loose. I can spin it by hand and it will revolve about 5 times. I think your right about to much air pressure. Unfortunely the compressor dosen't have a regulator on it. I'll have to try it out on the big compressor in the garage. That one I have a regulator on it.

I'll get to it some time. Right now I need to mow that dam big lawn. I think I could make hay it's grown so much.  :doh:

Well got the grass mowed. Then it rained. Lucky. ::)

After a bit of lunch I went to the Metal Source and got some aluminum plate and a round 2.5" bar for a total of $93 USD. $2.25 a pound. 41.5 pounds worth of aluminum.  :bugeye:

After I carted the stash into the basememnt I decided to give the Rocker Engine one more chance. Seemed like threatening it to make an ajustment with a 16 pound sledge and then drowning it in WD-40 worked.  :hammer:

It sprang to live and has been running good now. So it'll be on to making that fancy base for it now.  :thumbup:

Thanks Roger, that WD-40 made all the differernce. The thing I don't get is that I used a very light weight oil on it before and it didn't seem to make any difference. I did notice that it's very finicky to air pressure though.

Cool beans!

After you run it for a while, disassemble it and wipe off all the black oily stuff from the wear & WD-40.  For some reason, this one doesn't like oil.  I oiled mine (watchmaker's oil, from my dad), and it stopped it cold.  Cleaned it all off, and it runs like a champ.

So, tell us what all the aluminum is for.

Hi Bernd
Glad to see that you got it running. I think that "threatening it to make an ajustment with a 16 pound sledge" may have had something to do with it. :lol:

 :offtopic: Glad that the rain waited till you finished the lawn but now its got a head start for next week. Thats the beauty of a nice place in the country. There is always lots to do to keep it up. I guess its the price we pay for a 2000 sq ft work shop.

I know that you are planning on posting a vid when you get the base finished so I'll be watching for it because :worthless:

cheers  :beer:

Way to go Bernd  :thumbup:

I found mine a bit on the temperamental  side when it comes to air pressure and lube

Now all we want is the base   :poke:

Have fun

Sounds like you're having fun Bernd  :ddb:

Now all you need to do is make that massive aluminium base...... $93 seems a bit excessive for such a small engine!
But I suppose if you want it to look different then a 41.5lb base would certainly do it!!!  :lol:



As Don pointed out.............    :worthless:   :poke:   :)

Ok, first of the ali plate is for some jig plates. I need to finish my indexing tool I started which will use the 1.2" thick olate. The other plates, 1/4" and 5/16" will be used for tooling plates for the X-2 mill and Sherline mill.

The 2.25" round bar, of which I'll only need about a 2" long piece is going to be a part for a car a guy wants made.

And I'll be posting with pics when I get ""
 :lol:

Well this whole project started back in July. I'd have to say I'm working for the "Longest time it takes to build a Rocker Engine Award."

I had trouble getting the darn thing to run. Then rleete suggested I squirt with some WD-40. I'll be d@%&*, it worked like magic. I ran the engine and it got a good breaking in and to prove it I made a vid of how easy the thing runs now.
As you get to the end of the vid you'll here something like a piece of steel dropping on the table. That's the piston popping out as I try to start it again.

This is only my second attempt at making a movie with Windows Movie Maker so the quality and content isn't that great. So here's the movie. I'm hosting it on my own web site. Why? Because I have political issues with the video hosting companies. And lets leave it at that.

Rocker 1

Next will be a base to set it on. Hope it doesn't take as long as it took to get here.  :lol:

The clicking noise you hear is the autofocus of the camera. Kind of anoying. I know I can turn the auto focus off but then you'll get a more blurred picture.

I made another video of the same set up. Looks a bit better than the first one I made.

Looking good.

Now, take it apart, clean it in alcohol, and reassemble it dry.  You ought to be able to power it on lungs.  A little break-in is all it takes.

Oh, and get the base done!

Looks great Bernd.  :clap: :clap: Maybe you can get a light weight aluminum air tank and fit this in your boat. That would be an interesting project.  :smart:
I know that you really don't need anymore new projects but just in case you get bored. :lol: :lol:

Thanks guys.

I was hoping that it would play for a majority of you guys. I can also upload the mids in in .MOV format. It might take a bit longer to download and the picture is smaller but alot clearer.

BTW, I took a bit more time to video the second vid. I made sure that the lighting was better and shut off the auto-focus feature so it won't click like it did with the first vid.

Now to get busy on the base. Mmmmmmmmmmm...........light aluminum air tank. I don't know Don.  :scratch:

Regards,
Bernd

When I mentioned about the boat and air tank I was thinking about something that Bogs said.

 :med:"Whether it be a bent nail in a bit of wood" :med:

And since you like boats, why not, it would be something different.

How about light aluminum air tank as the hull with outriggers for balance. That should serve as a base! :smart:

The vids worked fine for me.

Cheers :beer:
