Sounds like you've also been very busy!  Hope you enjoyed your travels with your new trailer.

Looks like a great start to your tank!

In that last picture, is the inner part a cone? Or is that just an optical illusion from the circular cutting pattern?

Good to see you back on this Jim, though now I feel even guiltier and need to get mine finished up....as soon as the Pearl is done.

Thanks guys. It's good to be back at it. Not putting in a lot of time each day, but gradually getting ramped up.

Kim, it is a cone. Helps to route the last of the fuel to the outlet.

Bill, once I get caught up to you, I'll be on you to lead me forward to the next step!  :help:  :naughty:

Turned the tank base over and re-chucked. Located and drilled the mounting holes.



Back to the lathe and turned the base to the requires diameter.



Then it was back to the mill to mill away the waste material.



Looks like some kind of art work.  :)



Cut away the waste, then after making some filing buttons (or in my case sanding buttons), I shaped the mounting lugs.



Here's the tank base and baffle (that will be soldered into the tube between the coolant and fuel tank sections).



Next up is the tank (s) tube.

Got the rest of the parts for the fuel/coolant tank finished up.

Cut the tubing to length. I need to go back and find out just what brass this tubing was............it was really tough to cut!  :wallbang:



Squared up the tank base and drilled for the fuel outlet.



Located and drilled a bunch more holes.





Got all the parts made. I'm planning on plumbing the coolant lines with hard line (like Bill did), so decided to wait until I get to that point before soldering the tank together. Well..........plus I need to learn how to solder stuff like this!  :shrug:



I think I'm ready to get started on the head.

Jim, have you made the baffle yet that separated the fuel part of the tank from the coolant part?  As I recall I used soft solder for all of the tank and fittings, a lot more forgiving and the strength of silver solder really isn't needed here.  What you have looks great!!

Thanks Bill.

Yes the baffle is made. I remember you mentioned in your thread about using soft solder. I'm planning on doing the same.

It's been fun to get back to this project.

That tube was probably C260, aka cartridge brass - no where near as nice to cut as the c360 brass is, but in some shapes its all that is available.

Thanks Guys.

Took a deep breath and got started on the head casting.

Chucked the head in the 3 jaw in what seemed to be the best position and turned it to the correct diameter.
 


Centered the rotary table on the mill as a starting point and moved the chuck and head over to the mill. Used my fly cutter to mill the valve guide part of the casting to the correct height.



Located, spot drilled, drilled and reamed the holes for the valve stems.



Located, spot drilled, and drilled the mounting holes.



Next up is the inlet and exhaust ports

Continuing on.

Moved the RT to vertical and used Bill's method of rotating it so that the valve guides were horizontal.



Then I cold locate, spot drill, drill, and thread the exhaust port.



Rotated the RT 90 degrees and did the same for the inlet.

Two things just happened:

I just realized how small this engine is: Sherline chuck!!

It never occurred to me to have the fuel and water in the same tank like that. I always assumed just water. DUH!!

It could never happen anywhere else.

Thank you,
