Les Chenery rotary engine 1:5

[awake]

Rudirk, I am so sorry to tell you, but in your photos I spotted a significant problem with the Clarkson. However, good news - if you will ship it to me, I will be happy to work on it and fix it for you, for free. It might take me some time to complete the work, but I should have it back to you within 15-20 years.



Which is another way of saying, I am experiencing tool envy! Looks like a nice machine, in good shape - have fun with it!

 

[Rudirk]

Oh my dear...
Please tell me your address . I’m happy to find someone for repairing the grinder.
And so fast.....

 

[Rudirk]

What kind of screws are that ?

 

[Peter Twissell]

Ooh - nice!
Do you intend to make a cutter grinding attachment?

 

[Rudirk]

With the new mashine I got a few tool parts . Now I am testing what I could do with this parts. I will grind tools for my large building the rotary engine. First I build a tool to fit SK40 tools.

Oh, you fell for it? I mean, oh, good! Well, in that case, I'll even pay for the shipping. I will send you a "genuine certified cashiers check" for $10,000, which will be way more than you need. You cash the check, ship the machine, and send me the difference.* Oh, and by the way, I am not a Nigerian prince, but I have some friends who are, and I'd love to put you in contact with them as well.

*I guarantee the check will cash just fine. Of course, 30 days later the bank may ask for the money back, but hey, who worries about what will happen 30 days from now?!?

Hard to tell from the picture. The one on the right looks like it could just be a regular thread that has been worn/blunted from long use. The one on the left could be the same, but a bit more bunged up.

Have you tried any standard connectors in these threads (gently, of course)?

 

[Rudirk]

No, I have not tried any connector because here in Germany it’s not easy to get connectors with inch.
It’s not easy to find a idea how to clamp something.

i think this is a good idea.

 

[Rudirk]

This is the result from today . I machined a cylinder with a 25 mm while for the ER collet . The screws are metric now
The milking tool is only a example and for testing 25 mm whole.

 

[Rudirk]

Today I made a Adapter plate for turning the tool holder 90 degree . Now it’s better for grinding lathe tools. In this position I have only turning the Tool for grinding the other side.

Good progress!

 

[Rudirk]

Hallo, here is the next step.

That is the material for the front and back over.

 

[Rudirk]

Next steps are done . Everything nine times.

Looks good. I still have a hard time believing that this type of engine actually propelled an airplane in WWI

 

[Rudirk]

Why ?

 

[Peter Twissell]

The rotary design allowed an air-cooled engine to be built at a lower weight and with less complexity than the conventional layout designs of the day.
People are still flying restored and reproduction aircraft with rotaries today.
The Fokker DR1 fitted with a rotary was a very capable aircraft.

 

[Richard Hed]

Why ?

I am assuming this is the type of engine that the engine rotated. All that mass had to be balanced, if a piece ;was damaged and flew off, it would become immediately unbalanced.

 

[Rudirk]

I have a problem with mashing the fins.
I it right that the find are 0.53 mm thick ?

When I saw this photo , I can’t believe this.

 

[Rudirk]

this is the drawing.

 

[Rudirk]

Di you think, this is a possibility to grind the tool ?
