Hello, I have lost my job and I have put the project on the shelf. I need to get certain tools, and tools are expensive. I just don't have any extra money at the moment .

I made a trial valve guide today. This should be much better. I hope that I can get the press fit sizes right, I seem to always over shoot my dimensions when I get down to the last few thousands.

Here are two more photos of the rockers mounted. I am going to need to make valve guides because there is not enough support in the head the way it is now.

More work done on the engine.

Seeing that photo makes me feel less bummed out about my experiment. I have learned a lot so far. I'm going to finish this project failure or not. Thanks for sharing. It's good to know that failure is just a part of the process.

I did some more work today. I cut the roller tip rockers out and parted off 4 303 stainless roller tips. I still need to mill the mid section of the rocker arm for the 1/4" bearing. I also need to hand finish the parted off roller tips. Here are some pictures of today's session in the workshop.

Here are some pictures of the cylinder head with all the holes drilled for valve cover, rocker studs, valves, and push rods. I didn't plan on making separate valve guides, but there is just not enough material in the head to serve as valve guides. I have not cut the seats yet either. I have a...

I did a practice valve seat cutter copy based on Steve's design. I did it with aluminum to run through the operations before trying tool steel. I'm not sure if it would be cost effective since I would need to get a torch outfit to harden the tool. It may be better if I buy a 45deg off the shelf...

Sorry guys I don't have any photos of my progress but here is what I have done the past few days. 1.) Drilled head bolts, rocker arm studs, push rod holes and valve guides 2.) Drilled camshaft bore. Still need to make a 5/16 flat drill to make the camshaft bearing pockets I found an error...

Things are starting to stack up... I really need to try to refinish the valve cover groves. The camera is giving it to much justice! I still need to cut the valve seats and ream the valve guides which I will need to order. If I ream the guides for 1/8" what size drill do you recommend I use?

Thanks Paul, I appreciate your input!

I have a question about what to do for the valve guides? would drilling the guides be good enough or should I ream them? The cylinder head material is C360 brass.

Now you need to print the intake manifold. About how long did it taker to print the block and heads?

Looks awesome. it is going to be nice.

Valve cover completed. I was not happy with he way the groves turned out. I used an 1/8" 4-flute end mill and used an engraving operation. Oil didn't make a difference. I will try to hand finish this to make it better. Any tips for the grooves? For the most part everything else turned out ok.

I wasn't even born yet, it would be another 10 years (1968 ) before I popped out into the world. I'd give that tool an A+

Thanks for the info Greg. I was break chip drilling after every 0.025" at 2800 rpm and the bit was coated I believe with tialn. I ended up manually drilling with a different bit making longer chips because I believe the smaller chips were building up and not able to clear out of the hole. Bottom...

Hello Guys, Started to machine the valve cover and nothing but disasters, well maybe more bad luck than disasters. I started to drill the bolt holes and noticed the drill bit screeching and then locked up. The chips got clogged. Restarted the CNC code and more problems with the drill bit...

I am just a kid then at age 46 and a half. :D My .2" Starrett edge finder does not kick out well usually in one of the x or y axis. I can't remember which one. So it will kick out fine on one axis and half as much on another axis. Regarding magnetism, can this condition occur if using only...

It looks so cool. It must be satisfying to hold the design in your hand and to be able to look at it in the real world.
