The part is engine holder .Pic .says more.
I hope it will not be so terrible unbalanced.
Neil I think that centre of mass is the same on both cranks. Difference between these two cranks is in firing order.
"Balanced" crank has less...
Why is first crank balanced and second one rocking ?
I think there are different torsional stresses - in small engines negligible .
I agree engine is not balanced so well so I have two lead counterweight opposite each crank pin.
Important is two crank pin up two crank pin down.
I have built "assembled " crank shaft again .
This is not as easy way to machine crank shaft as it looks on first sight .
First is needed to drill...
Thank you guys.
My thread to Eso engine
Speedway races were popular in 1968 in Czechoslovakia . I was big fan .
I have built little JAWA ESO speedway engine to remind my youth.
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...
I use these simple punches for shims up to 0.25 mm[ATTACH] [ATTACH]
Could you please send detail picture of Holt engine water pump?
Will you machine water pump or just simple siphon cooling.
