Hello All!

Spent the afternoon pressing in all the valve cages. I made s simple drive dool slightly smaller than the ID og the cage and pressed them in a drill press. I like the fact that the press fit does not need to be very tight because the cage cant be shot out by the compression of the cylinder.

I also started to make some valves. These wont go as fast as the cages.

Stand By!

Hello all!

All 40 of the valve blanks are completed. They take forever but it will someday be worth it.




To cut the slots I used my ER11 collets. I was able to put the valves in backward and slot the stem for the E-clips. I have an insert holder and a .020 slotting tool. Makes it easy to have a nice sharp tool because I stink at grinding tool bits.








Then I made a few test pieces. I chose not to reduce the size of the stem at the head so I could hold the valve real close for rigidity. I took a light cut accross the face. I want the valves flush in the head and the hole for the valve cage is .250 so I reduced the OD of the valve down to .245.

 

Then I cut the valve angle into the back surface.



So now you all know what I'll be doing tomorrow!!

You got your wish Sam!!

Hello All!

Finished all the valves tonight. Everything went according to plan.




Had a little extra time so I got a jump on the rocker studs.

I've really enjoyed watching this. I have a question, what spark plugs do you use for an engine like this?

I will be making my own. They will have a 8-40 thread. Say some prayers.

Hello All!

I finished all the bottoms and all that is left is to mill the hex on the shaft so they can be installed. For that I just used the rotory table in the mill with a collet holder in the center of the table.  I have made 120 pieces in the last 2 weeks and now I have to make the valve spring retainers, 40 of them.

Enjoy seeing this come to life. Maybe some of your enthusiasm will rub off on me.
