Combines Solid rotor mod possibleIJ

Del, Unfortunatly it is going tough to modify a Sunnybrook solid cylinder.You would have to do some major cutting and I don't think that you want to do that.How is the rest of the machine set up.ConcaveIJ Stacked helicalsIJSeperator grateIJWhat crops are you dealing withIJMaybe we can do other tricks to get the job done without changing the cylinder.More P1 and P3 mods. are in the works for next year.Ideas for protos are in mind for this winter.

FYI St. John Welding already has a solid rotor which uses p3 bars, and can be adapted to use p1 bars or a combo of both, also. As I understand patent is pending. Check with Terry at sjwelding@stjohnks.net -- Hope this is some help.

Three years ago, I put in the sunnybrook solid rotor, Schwerin concave with every other wire pulled and the front 2 or 3 spaces blocked off, Schwerin constant pitch helicals (chromed channels),and a new cage. The '84 N6 was new to me at the time so I wasn't very knowledgeble about mods were avalible. The cage has 1x1 squares, no seperator grate, and no extended concave.

Del, The seperator grate covers you read about are for the grate that is in the P3 systems. The seperator grate in them machines have twice the cross bars and some wider wire spacing than the seperator grate that Hyper has been putting in the P1's. With seperator grate that Hyper is putting in the wires are spaced narrower so they won't plug with broken cobs and will carry the straw well. Also with half the cross bars there is less chance of rolling the straw into a rope and or break cobs. The reason we suggest removing every other wire from factory seperator grate is to prevent plugging it up with cobs which reduces seperation area. Removing every other wire is eazy to do compaired to raiseing wires or narrowing wire spacing or removeing every other cross bar,ect. We install cover kit over that factory seperator grate of the P3's and it is made of similiar material as the rest of the cage. We find that the factory style grate will overthresh the easy to thresh crops like canola and sunflowers which can overload the shoe. We also notice the factory style grate can roll the hard to convey straw like edible bean straw, barley straw, green milo,ect. Maybe the Hyper style grate wouldn't cause the problems that we see with the grate of the P3. Maybe the half height cylinder bar setup would help reduce the problems I see with the factory seperator grate also. I don't know if anyone has run the half height or steggered height cylinder bars in wheat or any other crop other than corn and soybeans. I did run some half height bars in corn this fall and had a lot more hole and half cobs out the end of the rotor instead of all 1_4 cobs and noticeable less power used. You could remove every other seperator bar on your Sunnybrook rotor to accomplish the half height trick for your corn but unsure if you could run your other crops like that. You would be wearing the mount area where the bars are removed and you would be best to check with Sunnybrook to see it wouldn't structurally weakening the rotor. Sounds like you have a nice setup now other than you maybe have reverse bars still installed. What is your limiting factor now or where would you think you can improveIJ Good bye for now. Dan

I have a dumb question. What is the advantage of a solid rotor over the standard rotorIJ

There is no such thing as a dumb question. The advantage that I see is that cobs don't bounce around inside the rotor. The material stays against the cage. Also dust or material doesn't rest inside the rotor when stopped causing it to be unbalanced when first started. It also is a lot heavier so when a slug of material goes into cylinder the higher inertia doesn't let the rotor slow down as fast.To much of this and you probably should do some header work to solve uneven feeding.Hope this answers your question good enough.

Del. You answered my solid rotor questions. Thanks. John
