Rod boring lathe
More pics were requested of my rod lathe. This machine is specifically built for that job. The machine turns the boring and the rod travels with the carriage. I have a facing tool at both ends of the bar so machining the bore and both sides of the rod can be done with one setup operation. I don't do many T rods anymore with it, there's no money in it. I have my customers buy them from the vendors. My centrifugal pouring process is too time intensive on T rods. I have done rods on this machine with over three inch journals and it has the tooling to do things as small as the tiny rods that move the sleeves in a Willys Knight engine. It can also rough or finish bore bronze bearing shells for other engines and I use it to rough bore T main caps to .050" undersized in large batches.

Re: Rod boring lathe
Thank you for posting this. It is very interesting.
Do you have any photos of your centrifugal pour setup?

Re: Rod boring lathe
I have them on an old iPad I need to get a new touch screen on. With the new format I can post them. It's very exciting, the whole mold is spinning at 1500 rpm and any leak results in 900 degree babbit flying everywhere. Leaks are common, too. But the end result is the most dense, contaminant and gas inclusion free bearing possible. Centrifugal force is the key. A better bearing by far than Ford supplied but time intensive. I will get pics and info up as time permits.

Re: Rod boring lathe
Erik, thanks for posting the pictures of your rod boring lathe. Is that a cutter in the chuck? I have never seen a lathe like this before. Interesting.

Re: Rod boring lathe
The cutting tool in the chuck faces the side thrust portion of the rod and also cuts in the radius at the end of the bearing. There is another one at the other end of the bar.

Re: Rod boring lathe
The facing head was not on the back end of the bar when I took this photo.

Re: Rod boring lathe
I made an attachment for my old 9" South Bend lathe that looks remarkably like that. It was anchored in my milling attachment for adjustment and bolted to the cross slide with a boring bar placed between centers. It worked so well that I did the rods in a 1934 model B engine several times......by making mistakes. Finally got 'em though.
Sorry now that I sold that truck..............
