I have been working on the late Bob Shores Peewee V4 for 6 or so months. I have all the castings machined. I am slowly working on finishing the heads. I guesstimate being 25% finished with only 95 % to go!!

That is pretty cool Steve. Keep the build pictures coming.

I have finished the valve cages, valves, and retainers. As soon as the rockers are on the head i will update with some photos.

I should have had the heads done by now but I made the rocker arms wrong. I started a new batch with a completely new design. Easier to make and more interesting to look at. If I dont screw these up, there should be some photo's by the weekend.

It's a 1928 Ford. She goes out for a ride now and then but to unleash all 35 horsepower on the neighbors is just unfair.
Nice. My dad and I restored old cars years ago. We rebuilt a '62 Studebaker Lark that dad drove as his daily transport for years. Now he's got a 1964 Avanti sitting in the garage, still awaiting completion.
I'm a bit of a car nut, but unheated garage + NY winters = indoor hobby. Model engines fits the bill.

Finally moving forward. Rockers are not perfect but they make me happy. Guess thats part of learning. The heads are complete so I think the cam is next.
Camshaft went well. I developed a system for cutting all the lobes at the same time. I took the Bob Shores method but modified the cam fixture to allow my cutoff tool clearance so all 8 lobes could be cut at the same time. I made a spread sheet so i would know what lobe to cut and at what degree angle. The method worked well and I completed all the cuts in 3 hours. Including making the blank and filing and polishing the nose of the lobe, it took less than 5 hours to get this far.

It is a modified version of the fixture that comes with the Peewee plans. I thing Dick Upsure used the same method. All it does is hold the cam off center the same amount as the flank radius of the lobe. In this case .521 inches. As the fixture swings the cam, a cut the depth of the desired lift is made. Then the cam is rotated 5 degrees and another cut is made. Enough of these cuts and a lobe starts to form.
I have been trying to write a paper on the procedure, but after reading it, I confused myself. It needs work in the form of illistrations. It is one of those things that you can write down and it's confusing, but if you were in the garage for 10 minutes you would catch on. It's alot easier to show you than tell you. It's a work I plan to finish.
