Critical dimensions, getting picky huh. The center hub is 1/2" x 3/4".
The index holes are .200" on a 4.0 diameter spaced a 18.947º. In the old
days I would be happy to say, just buy an index plate from me :-).

Tim,Thanks - someone will appreciate it. I'm going to save/file this and hold - in case I ever need a 19-hole index plate.For "accuracy" purposes, can you tell us what some of the key (critical) measurements should be. A number of the printers & copier/printers out there do not necessarily
Here's a template for an index plate that has 19 holes. The time spent
was trivial.

Mike, I knew you would be using crank handle method. My first thought is to
simply make a 19 hole index plate. Those prime numbers really throw things
off. In my mind I multiplied 19 x 2 to equal a 38" pitch. Then you could
figure out the number of cranks. Ah, but then we have a new
It’s actually Tims document he made it after looking at what mike did credit to
both i think

Digging around the archives i found this for you all that are interested in
crank handle indexing but might be having trouble following it
And how to do it

there is a nice chart tim did years ago that
Thanks Bill, By backing it off 1/19 per revolution, every flute gave up
just a little but that .05", 19 times was enough to add a flute. There
is always a way, CNC would have just been a number but I am See and
SEE. LOL Oh and a little math.
Mike OK

Thank you Mike.Ive been working on this math problem for over an hour. 19 is
a ...!@#. 18 is much easier TO work with. ;-) Again thank you.C.A.G.

I see very clever mike I think I would have just done 18 and had the spaces a
little wider than the flutes or widen the flutes a little
Very clever your still the man

That is right, a 4.5 inch pitch when cranked on a 4 turns per inch acme
thread will give you 18 turns to complete one revolution.
Here's what I did. I clamped a piece of cardboard to the rail to use as
a pointer and placed it to where I could point at the duplex gear face.

You got me the closest I can get is 18 divisions using a 4.5inch pitch 1 crank,
not 19 too yearly in the year for my poor old brain you will have to enlighten
me on this one

You are correct that I used the "Crank Handle Indexing" But what math
would you use to create 19 indexes?
I have no idea how heavy they turned out but I did what I could to
lessen the load.
Mike OK
