Did you silver soldered crank shaft parts?

Tapsa you are welcome . You have the same machines like me. Are you interested strictly in steam engines or you are planning to machine combustion engines too. BTW congratulation to winning World Hockey Championship.

I use these simple punches for shims up to 0.25 mm

Hello gbritnell Could you please send detail picture of Holt engine water pump? Thank you

Will you machine water pump or just simple siphon cooling. You wrote // Don't think I will return to L.C. soon....// is this engine your last one?

Good runner congratulation

Hello all Maybe somebody will find this useful. I have drilled main bearing housings for my new four cylinder by this way

please send some pictures from drilling long crankshaft hole .

Hello Minh Nice work I like your rocker arms but just my suggestion : on the push rods you have some brass parts //probably for setting valve clearance // do it as light as possible because heavy push rods decrease engine performance and rise stress on cam shaft lobes.

Hello friends Short time ago I have finished my cnc router and started to learn how to work with it. My first project was unusual very simple 3 phase brushless motor . I got this motor design idea long long time ago so I had simple and "useful" project for my cnc learning and at the same time...

Beautiful engine what capacity ccm will be your Argus ? I am working on 4 cylinder too but simpler one something like Henderson , FN or Pierce motorcycle engine.

Hello Klaus thank you for your drawings offer but I did not ask for it. //just misunderstanding // Anyway what is your next engine project? Did you hear about NOTRE-DAME cathedral burned I am so sad.

Thank you Wizard You are completely right main problem is - as you said - figuring out where the distortion is coming from. Maybe building a crankshaft fixture with gauges to find the points of distortion would help.

Hello Klaus Could you shortly describe how did you machine crank shaft ? Do you have your own special machining method ? Do not worry about german language we have GOOGLE TRANSLATOR. Thank you

Did you cast the middle part of engine - crank case - ? Smoothly running engine well done.

Hello Klaus Nice to have you here. Your engine is beautiful . Can you inform us about basic engine dimensions ?

Wizard thank you for 2x4 explanation , here in Europe we use mainly oak wood for such purposes. To straight crankshaft properly is ART I have tried to do it without success .

Mechanic boy I was not able to release loctite glued joint with heavy hammer in spite of this fact crankshaft can be hot mainly during cutting unneeded parts.. Wizard excuse me I do not understand - what you mean // you can do it with a 2x4 if you really wanted too.// Thank you

Mechanicboy thank you for your crank shaft machining description but for 120 ccm straight four cylinder it probably will not be solid enough . Minh Thanh Thank you for this post . This GEOFF-H machining way //squeezing shafts in throw arms // seems to be solid way + I can use Loctite and D pins.

I reamed all holes in throw arms then pushed shafts trough these holes then secured shafts with screws and trough small holes drilled over each joint I applied silver solder //650 Celsius melting point// then cut off unneeded shaft pieces. Unfortunately i did not check assembled crankshaft...
