Egor's Engine Extra
« on: November 18, 2006, 06:17:32 AM »
Hello all, Spent the better part of the day traveling to town. I was able to buy the glue that will hold the displacer piston. It's called "Ultra Copper" and what I found out is it can work up to 700 degrees f. That is two hundred degrees hotter than I thought. Should work.


Started working on the piston and displacer connecting rods. Here is my first attempt.



This one is cut from .200 inch brass plate and the xyz cuts it out in a single path. Two small screws hold the collar to the rod and I found the unit hard to work with. Scrap that one. Back to the computer and a redesign. The computer program is Easy-Tracks and the change is simple.




This picture shows the new design of the bearing collar and connecting rod and the displacer connecting arm made yesterday. The two small screws holding the collar to the arm were upgraded to a larger size. The bearings used are a Z type.






A side view of the parts. A second similar collar and connecting rod will be used for the power piston. I will keep progress updates. This seems to keep me working harder to get this engine done. :0) Bill

  You do some darn nice work there Bill!  Keep up the great work.   I'm on the edge of my seat waiting to see the completed unit !   I'm shooting for next weekend to complete my little beast ( throw in a little competition for completion ) ;o).

I wish I had machining skills and tools like that.  I could be a real menace!  :-)


Couldn't you have gone with a one-piece connecting rod, and press fit the bearing?  Seems like just one less thing to worry about, as you've already pointed out that you up'ed the screw size for one reason or another.

Rod, The reason I went with two piece is the amount of plate brass available. The quarter inch square rod, I have twenty feet of the stuff. This one done like that would take twelve inches of brass plate. Cut out like you say would look a lot better but this engine is being made from scrap material found around the house and shop. When this engine runs..., thinking of drawing up plans and cad files to build more. Of course the plans are now in my hard to reach hollow spheroid.
