Hello All!

I made a few valve spring retainers this morning.

I turned the OD on a piece of 1/4 inch brass about an inch long and faced the end.



Then spot drilled and drilled the ID about an inch deep.



Then I used an endmill to make the flat bottom pocket for the spring clip.



Then I cut a groove deep enough to create the step in the bottom that will insert into the spring.



Then just move over the length of the step and part off the piece. Then starting with the step of making the pocket with the endmill, I continued until the inch of turned material was gone. It took 4 cycles of 1 inch of rod to make 43 pieces with 2 boo boo's.





That's it for the day. I have a half dozen or so club members coming over to hang out, eat, and brain storm about getting there stuff going. Should be a great day!!

Hello All!

Good day in the garage today. After pressing in my valve cages, I spent the day redrilling all the intake and exhaust passages. After that was done I came in the house and made some g-code and started on some rocker arms. I managed to cut the side profile and then after they were broken apart, I milled the slot in the top. I think I am going to make a fixture of some kind so I can finish about 6 at a time.

Hello All!

Started finishing the rockers today. Made a fixture out of some scrap aluminum. Wanted to do 8 at a time but the aluminum had other plans. I was able to make 6 at a time. The parts were drilled for a 2-56 screw and then the outer shape was cut. I'm not real happy with some of them so I may make a second batch. I do like the the way the fixture worked out. I may make a better fixture. No matter what I decide, I won't be doing much any time soon. Work is getting busy!

Are those slots long enough for the rockers to work? Looks like they'll bind up before the valves open

all depends on the lift of the valves...... being that thhe rocker studs are so close to the valve, I'm guessing isn't gonna be much

They will work fine. The lift is only .070 inches.

Hello All!


Well, I have designed a new fixture for the rockers. I have written the new Gcode for the fixture and the rockers. The way I would like to proceed is to use the CNC machine to cut the fixture out. This way the X and Y axis will already have reference and save alot of setup and everything will have a high probability of coming out real nice. The problem with all that is the amount of time it will take to do all that. I was hoping to do it on a weekend so I will have all day and wont be out in the garage late.

Not having a day off last weekend and this past weekend, I have gotten tired of doing nothing, waiting for rocker arm day so i decided to make some lifters. I didn't take many pictures because they are a very simple part. I managed to make a full set of 16 today so i am half done. After this photo was taken, I turned the part around and faced off the little nub and polished the bottom real good. It will be rubbing on the cam so we don't want any sharp edges.

man/cnc is about 30/70 right now but once finished it will be about 50/50.
