Les Chenery rotary engine 1:5

[Peter Twissell]

With the correct choice of airframe, it is possible to fly with almost any engine. A slower flying aircraft with large wing area is more efficient and can carry a heavy engine with low power. The Wright Brothers had 12 HP from an 82 kg engine.

Hallo,
I have a question machining the Rear ball bearing housing.

her you could read ....and TCD marked.

is this my TCD and my starting point for milling the key way and boring the 18 wholes ?

 

[Rudirk]

I have an other question . This are the dimensions from my bearing :
5/8 x 1 3/8 x 11/32.
Is this the right bearing ?

 

[Rudirk]

That’s the result if the last step is wrong .

 

[Rudirk]

Now the summer is gone . Time to make further parts for my engine.

the bearings i used were of the rubber sealed type as i found it impossible to effectivley seal the rear bearing as in the Chenery drawings it meant a slight modification to the housing i think around 1/32" deeper?

 

[Rudirk]

Do you have a link for this bearing ?

 

[kitson]

Yes I will check my paperwork the bearings are stock items over here the only difference is the width Od & bore the same I will be in touch with regarding this matter shortly
