confused with colors
Ya I successfully installed my Dayton drum (Forward / reverse) switch to my split-phase motor, and it operates perfectly, both forward - off- and reverse. Here is a drawing that "Glen" did on "justanswer"

Thank you all for your help and I hope the attached photo helps other people wire their single phase motors to drum switches. (whew, sill it was a bit scary
when I tested it!)
Oh my motor had only two wires and the instructions on the back said to to switch wires to change direction, and after careful inspection, the two wires (detached were one circuit, while the other two wires on the terminal board was the other (direction) circuit. After detaching the two wires I had the needed four wires as indicated in the attached diagram.
You have the orange wire labeled as T=Orange. Which "T" is it?? I've got a Dayton Motor (3K617C), with all yellow wires, with the wires labeled P1, P2, T1, T2, etc. I'm assuming it is T4, since it is the only one left.
Your diagram is the FIRST one I've found that associated color with P & T labels!! Thank you, thank you, thank you!! I'm trying to switch out a 60 year old 1/2 Hp motor (before grounding plugs, etc.) on my Atlas 618 for a 3/4 Hp Dayton to get more UMMPH in my lathe.
I've got a Furnas Electric (out of Batavia, IL), style A-14 drum switch, and it's built like no other drum switch I've researched so far. Instead of 3 leads on each side, it's in a 6-point star configuration (two line-in, four line out=W, Bk, Rd, Gr[NOT ground]), and the moving part (rotor?) is solid -- pre-wired in bake-lite. I'm assuming I could just match up T5, T4, T1 & T8 with the four-line out.
I found an identical problem at
The Home Machinist! ? View topic - Reversing switch wiring how to question. , only the leads don't use P1, P2, T1, T@, etc. I can probably assume (from the 2nd jpg, inside middle right) that lines 1 & 3 go to the starter windings, which would be line T5 & T8, and Black line-in goes to "A" and White line-in goes to "B". Leads 2 & 4 have different colors (in 1st jpg), so not sure which would be T4 & T1?? Would it matter, since power would be sent first through either (depending on direction)??
I'm also assuming that the Furnas Electric R1 drum switch (in EPAIII's post, see 3rd jpg) is different from the A-14, since the split-phase diagrams are also different. From the wiring of the switches, they seem identical! So, are the corresponding leads (lines-out, line-in, starter windings) on opposite sides (as in the 2nd jpg, split-phase), or mirrored, offset by 2 (as in the 3rd jpg, split-phase)??
Will it be possible to re-wire this, or do I have to bite the bullet and purchase a more "modern" drum switch (like the Dayton)?? Very confusing!
Any help would be greatly appreciated.
