Well I have had 2 people tell me they have completely modeled the engine and one more who has only a few pieces to go. They have reported the same missing dimension on the head. Other than that I think I'm out of the woods on the drawings. I don't see them changing much after this one update. The fact that it could be drawn by 3 people makes me believe there is enough info to build to completion. The plans have been updated to version 1.01. I'm going to wait a few weeks to see if anything else pops up and send out a fresh set to those who have purchased already.

Other than that i'm going to stick to the original plan of finishing the V8 project and then finishing the blower conversion. Hopefully I'll get back at it next week!!!

If interested, plans can be purchased for this engine.

Hey Stece could you check the lift numer again. It does not look like the cam lobes in your picture(;-)

(;-) TP

.070 Lift

That's what I designed and it looks alot like my model. Maybe the flank radius is throwing you a curve ball.

Steve what is the basic spec on the lobe BaseCircle ? Lift?   firing order   I would like to model a basic cam like yours and see how it works in CNC.

(;-) TP

Base circle = .350
Flank Radius = .696
Nose Radius = .125
Lift = .070
Duration = 280/280 degrees (140 cam degrees)
Lobe seperation = 110
Firing order = 1,8,4,3,6,5,7,2

Steve about how long does it take to produce a camshaft ? Crankshaft?

Just curious,(;-) TP

1 hour to make the fixture
1/2 hour to machine the blank
3 hours to machine all the lobes

Crankshaft was about 6 hours start to finish.

Steve are you about ready to build a CNC cam grinder for those puppies ?

(;-) TP

Nope!  In the time it would take me to write the code I could make 2 by hand.

Scratch water pump off the list. Instead of tapping a hole to thread a fitting in the pump, I decided to recycle the fitting in the water neck and just solder it in. I had to sand blast the paint off and the rest was easy.



Still going to need some paint but the pump is 100%

The electrodes were made .002 larger than the hole in the cap. The wire gets threaded thru from the bottom and the brass is pressed into the cap.
