cschwartz106, just think your engine is just waiting to be finished, it is still on going.

School is a good start but sometimes kids struggle till they get in the real world and find something they are really interested in and are good at.I think it is great to see them improve on their own through life. Our daughter was always building something out of shoe boxes or jam tins so it was a ...

Yes I think she is pretty clever, she is a mechanical engineer. Thanks for the congratulations, it was great to build an engine and see it run. Now onward towards the next project.

Back again, I have recieved some good information from my daughter regarding my little engine. She sugested that the aluminium might be spreading the heat too quickly, so I found two test tubes to work with the first I probably heated it too quickly and it broke at the end.The second one I gave it a...

I did use brass on the fly wheel, but I have seen them made out of aluminium. My power piston has a 0.0015 inch clearance, and cschwartz106's tolerances seem similar.

Due to work committments I may not be able to get back to you at the moment.

The battle still rages!!

cschwartz106 I agree with you about the drawings and the tuts, even after I got them translated they were a bit of a struggle although, it said in the tuts this is a test of patience. My engine still won't run I'm trying a smaller displacer tube and giving the end space 3/8 end clearence this should...

I made another displacer tube it has .020 overall clearence on the sides and .040 clearence on each end.When you disconnect the the power piston from the main axle and move the power piston you can feel the suction or pressure, it has .0015 clearence. If you reconnect the power piston and heat the d...

G,day all, just had slight set back when the test tube I was useing as the displacer cylnder cracked but I am still pressing on.The engine is in bits now so I thought I would run some numbers past you and see what you think. displacer is 21.33mm in dia the bore is 22.2 mm dia the stroke is 26mm long...

Hello all, I have been bitten by the stirling engine bug.I have built a walking beam engine so i thought I would have a go at a chenapan model. At this time I am having problems as it refuses to run, I am about to give the power piston a little more clearance and see how that goes it has .002 inch n...
