Jack,
A fine looking engine. :bow: :bow:
Do you intend to use soft or hard solder for the needle valve. ??? I have used soft solder in the past but I can't say it was all that great with stainless steel. On my roundtuit list is replacing with hard solder. Please let me know how you do it.
Best Regards
Bob

Hi Bob The reason why my needle is not soldered in is because I wasn't sure if I would do it. I am glad you said something about the soft solder because that is all I have and I am eliminating that right now. I have had Model A Fords circa 1928 to 1930 since the 1970s. I have rebuilt several engines completely including the carburetors. The fuel system on these cars are gravity feed. The don't have a fuel pump so basically it's the same type engine I am building. There are two needle valves on a Model A carburetor. The smaller of the two in the picture is the idle valve. It is solid brass. The other one is the high speed valve. The point is held in a collet set up. The point on this one seals in a aluminum hole and the point on the shorter solid brass one seals in a brass hole. I think this may be a better system. But tomorrow I am going to stop by the MSC Industrial store and find out what they have in hard solder. Then I will make the decision to use solder or change the design a little bit. I also thought of drilling and tapping for a small set screw from the side of the Needle Valve Body. Here is a picture of the three Needle Valves. Jack
I am making the valves from drill rod.
The blanks still need to be cut to length and lapped. I need two the third is just an extra one. I needed to take the snowblower off the tractor and put the mower on. Then I cut four acres of grass. Didn't leave any time for much shop work. Jack B

Progress report on Exhaust and Intake System. I have been winding springs, lapping valves and making a series of small parts for the Ex. & In System. They are all straight forward machining so I didn't bother to document their build. There are still several parts to be made for this section. It has turned out to be a very interesting project.

That's looking real nice Jack.
I can't wait to see and hear it run.

This is another part for the Intake & Exhaust System. This one starts out as a rectangle shape block of CRS.
Here is the finished part. It is called the Governor Pivot Arm. I have to make a simple bushing to attach it to the engine. I will try to make it tomorrow or Saturday and post a picture of it on the engine. This was an extremely difficult part to make. They were many setups. I also found the drawing very complex and hard to visualized. Jack B

Hi Kel
I worked on it on and off for four different days. I put the drawing in my scanner and made it larger. That helped some but I needed more. I turned the drawing inside out and that helped a lot. Last night I thought I had it all figured out but this morning I saw I was wrong. I worked on it all day taking very light cuts with a 1/8 diameter cutter so it wouldn't fly out of the vise. I was finally done about 2 PM today. I thrive on challenges and this was one. Jack

Jack B.,
Your correct, that is one complex part to machine. It would be difficult for me to wrap my mind around the drawing to visualize the machining steps involved. Very impressive. Keep up the good work.

Hi Bob
Thank You very much for this wonderful complement. However I know I don't come anywhere near George's high level of work.
I started work on the two sided Governor Exhaust Cam Unit today and hope to make some good progress tomorrow.

I have been away from this project for a while because of different reasons.
The next part is The Governor Exhaust Cam Unit. I found this part to be very difficult to visualize and machine. This picture shows the blank being turned in the Clausing lathe. I made an extra one and needed it.
I don't have a rotary table so I mounted a jig plate I used on my last project in a old four jaw chuck. The chuck screws on to the spindle of the old K & T dividing head and this becomes my rotary table. The whole setup goes on my old Index verticle miller. Everything is trued to dead center.
I am drilling for two 8-32 holes in the part and the plate. They will be used for holding and orientation.

Now I am machining the cam on the opposite side keeping them both in orientation with each other.
Finish machining this side. All that is left is to drill and tap three small holes. I will try to post the completed part tomorrow. Jack B
