Thanks Chuck and Others

I am trying to do a good job on this project because I am being critiqued by my real machinist friends at lunch.  Sometimes they are somewhat judge mental.

Today I made the little part that is the reversing quadrant. A tiny simple little part about 3' long and 3/8" wide with two holes, OH and a curved part as well, I just fired up the CNC mill cut the piece and then put it on the surface grinder to clean up the two faces and then made 2 little spacers so that I could mount it on the engine, and sit sit back and admire about 5 hours of my handiwork.

I told you that this particular build was going to get interesting. :naughty:

I managed to find some time to work in the shop this weekend even thou I had to attend a birthday party and help my son in law haul supplies to his new school teaching gig. You wouldn't believe the stuff it takes to setup a classroom for 4th graders.

Anyway I worked on some of the valve linkage including the connecting rods and eccentrics. I also managed to make some of the reversing linkage. I still have a boatload of small parts to make, but I'm having fun in the shop.

The plan is to have this finished by September 1 .... I think that I will make it :thinking:

Today I got a chance to make the little parts at the top of the reversing lever. Basically a small aluminum part with a brass handle that is spring loaded inside of it that pivots on a 1/16" shaft and it locks into the curved piece at the top of the engine but I can't cut the notches until I get it running then it will lock into forward or reverse.

Thanks for looking

Today after finishing the Oil Box I decided to make the Crosshead Oil Ports, a couple of simple little parts out of brass with a radius on one side to match the outside of the crosshead and then drilled. They then had to be silver soldered on to the crosshead and then then the little copper oil lines had to be bent into position from each one up to the oil box.

This project should be running soon

If I didn't do this correctly Please help an old guy out and fix it, you won't hurt my feelings. After all we all need to start somewhere.

Thanks

Jack :cheers:

I was able to watch it and glad I did.
Very nice runner with a good sound.

I think there's a way to embed the video in the thread but I haven't done it in a while and don't remember. I'm sure someone will pop in with the answer.

What a lovely engine Jack, you've made a very good job of it :NotWorthy: :NotWorthy:

I've put right your video.

I'm always a little cautious about running and engine in mechanically by using the output shaft. I have had examples here, made by other people, and I have had to try to put them right, mainly by doing what you did. It is driving the engine backwards from what it is designed to do, and can put unnecessary wear on parts that shouldn't wear. I much prefer to wait until I can put air into it and get it running from there.
