my head is in the same place as b-child. is this using tools to fix another tool to make something to fix the tools to fix the mazda ?  This cylindrical grinder is getting rebuilt so that I can finish grind the eccentric shaft for the Mazda. My plan all along was to build a three rotor motor for it. However, the prices I got given to outsource the grinding of the custom made E shaft where ludicrous. No amount of ky jelly/Vaseline/wheel bearing grease would put a smile on my face for a shafting like that. Why three rotor? Because race car. Any car that sounds like a proper formula one car, generates big Leary flames and can break the speed limit in two gears, first or reverse, can only put smilage on my gob.... |

Yep. Grinder is at home. Nothing to do with work, but that said, once it's finished they can sub out grinding work to me. Not that there is a lot, but it could be used.

Got to try out the wheel balancer today. Roughly balanced the wheel without the balancer,ground a bit of 440c. It's a magnetic grade of stainless steel. Then a quick paint with a sharpie before flat ting on a bit of wet and dry. You can see the ploughed field effect I spoke of due to the wheel skipping along.  Same material,feed,speed,machine etc. But with a now balanced grinding wheel. Results talk for themselves.  Removed lubrication pump. Always good to see there was oil present  Removed a rather tired looking suds pump    Anyone up for a twenty minute challenge? |

I don't care that the car is in the background - I don't mind that I'm not exactly sure what this big lump of cast machine does - I love this thread - eventually the car will come back to the front and I'll love it even more

So. The twenty minute challenge. No scraping or manual hard work. Into the ultrasonic cleaner. Open beer. Ten minutes later,turn it over...  Not a bad effort. But,a funny smell.... Looks as if the magic smoke has been let out of it  Stripped down. Lots of nice little touches not seen today. Like a balanced impeller.   Apart from the lack of magic smoke to make it work,it looks to be in really good condition  |

Magic smoke. A well kept industry secret. We have been brainwashed into believing that electrical goods work in conjunction with randy little electrons. Big conspiracy theory. Actually, how all electrical items work,is down to magic smoke. A very well guarded secret ,is the actual filling of electrical goods with said magic smoke,during their initial construction. As we all know,once you let the magic smoke out of an electrical item,it never works again........

Ah you are forgetting replacement smoke can be purchased  However a man of your talents may have an easier job getting it back into the wires with minimal losses - rest of us mortals struggle with that!!! |

Ah i understand . I'm with you there , electrickery is the work of elves and imps . So much so that using a test board with flu made the magic smoke send 240v into my hands , each holding a wire . Despite being incredably painful the smoke made me laugh as i realised i could not let go of the wires like a cartoon .
Darn those cheeky little elves and their mischief - how i laughed !

I had to go back to realise what it was. That ultrasonic bizzo looks good. I'm all for cracking a beer while something else does the work.
Still reckon you need to start making a 5 rotor e-shaft.

Every rotor you add to the count adds 130mm to the overall length of the engine. Another 260mm added to the three rotor e shaft puts it in a position where the cylindrical grinder is too short. So three rotor it is........

So three rotor it is........ That is one of the best pieces of logic this year. Works for me. A bit like choosing the power of an engine for a build based on how long a pair of 11's you want to leave on the road. |

So become best friends with google translate or even better learn Swedish and have a read - rejsa.nu/forum/viewtopic.php?t=23282Yes, I have seen that before. He builds a quadrotor to go into a Volvo, and a friend of his, John, builds one into an Rx7 Fc. They are both on a couple of the rotary forums, and both post in English. He has the dubious honor of causing me about a years lack of sleep, as I saw how he had done his eshaft. I don't have the same equipment that he has, and I couldn't think of away of doing mine with the equipment I had. Each time I thought of something, it always went back to his method. It's a good method, that eventually I came up with adapting to the machinery I had !! |
