New bars on AC 40 combine cylinder, photos

Just finished these up last night. They are 1/4 in rubber vulcanized to 10 gauge steel. Then I countersank holes in the rubber and used steel rivets to fasten them to the old original bars. Should out last me.
Now got to rivet rubber to the shelling plate and put new rubber under the 2 concave bars. Should get that done today.

PS. Anybody remember why the bars are spiraled on the cylinder?

Looking better all the time! You are doing all of the things that I would have liked to have done. Very satisfying to see.

You got a break on the rain, compared to the Midlands, didn't you?

We got 9 inches for the week. we were very lucky. Last Sunday, the wind was terrible but we survived. How much rain did you get? How is your Dad doing?

We got around six inches for the whole week, along with some wind. Dad is doing well, we worked on a round baler today for a neighbor. Finishing up fall hay also. Was your sorghum cane all ruined by those aphids?

The rubber bars should be more gentle on the peas. A guy is advertising in the NC Ag Review for A-C 40 and 90 combines and parts, in any condition. There was a like new 90 a mile from here that got scrapped a few years ago. I had no where to put it inside. They take up more than twice the space of the 40s!

Garry, I did not get a good stand on the cane because it turned off 100 degrees and dry right after I planted. The aphids hit what few plants I had. The rain and 50 mph wind we had would have done it in anyway.

Looking good!

The spiral idea is the same principal as the Fox choppers, and the JD dura-drums. You use less HP when you reduce the immediate effective bar to concave or knife to bar area. It also helps with feeding, as there is a bit more bar in contact with the fed material at all times, as well as providing relief at the barfor material to feed into. Similar to using a scissors to cut a piece of rubber, or pressing a solid flat knife thru apiece of rubber.

Best of luck with your project.

You are exactly correct. Thanks very much.

It also provides the air blast for separation above the front of the straw rack.
