Bored a couple years ago I made this dwell style wheel for CVT ratio counting. Print it, cut it out, tape it, read it.
The attached PDF is much clearer.

A person could attach a piece of wire to the CVT case then bend it over the dial as an indicator.
Only need one revolution of the primary.

Just to be clear isn’t that for when your over 3 rotations on the primary? On 1 Revalution on secondary I had 4 fins left to make 3 Revalutions

reogem- well damn if that ain't trick. I got so use to Ridgways using the primary for the count that I'm really impressed with this. However just one question. I noticed that the 120 degree line doesn't look like it's in the exact middle of the of the arc between the 180 & 90 degree lines? I'm thinking it should be exactly 45 degrees, and it doesn't appear to be. Keep in mind that I'm old and my eyesight (and other things, lol) are going. Have absolutely no experience with NASA. Thanks Rick.

Turn the primary just one revolution. The secondary will only turn part of a revolution. For example if your ratio is 3:1 when you turn the PRIMARY one revolution the SECONDARY will turn 120° or 1/3 of a full (360°) revolution.

@wgc 45° mark falls approximately on the 2.67 ratio mark.
I drew this on my cad program it should be 1000 times more actuate than a sharpie mark eyed up with a bolt hole and a fender point..
FYI the red and green marks are at 22.5° intervals.

reogem- Thanks I'll disregard the placement of the line and and use this. I have all the faith in you brother, wasn't doubting, just my "curious minds want to know" thing. I agree with your more accurate statement although I never did that sharpie thing anyway. Thanks Rick this should make it a lot easier for people to get a good accurate ratio count. Everyone in the community should appreciate this as well. Bill

1/360th of a secondary rotation is closer than 1/24th of a primary rotation :)

It isn't the middle, 120 isn't 45 deg from 90, it's 135deg. (90+45=135...135+45=180)

CanadianKodiak- Well Geeze, thanks for pointing that out to me. reogem all ready stated that the 45 degree line would fall around the 2.67 mark. But thanks for the math class.

You obviously seemed lost, just giving you some guidance there bud, no harm done.

Well thanks, Bud. I was obviously lost but seeing that the conversation was between reogem and myself I didn't appreciate your comments. reogem answered them for me 2 days ago. No harm done.
