I have a Ron Hill pitch gauge that I'll sell.

[form-e one]

contact john meyers in seatt;e the best pitch guages and rake guages avaible... they are coppies of ed karelsons,,, the nearest you will get to a dial indicater/ie true pitch,,,

just remember rake is prob more important than pitch,,,,????

I think they need each other along with diameter and shape for fine tuning

john has ported me 3 v-rudes this summer and lots of unlimited raceing with jw,,,, we where 3mph over 1 mile record, this year with new karelson i built,,, just needed good water and no wind,,,

Just a Note

My family only races one class "A". We have over 30 props for the OMC, plenty for the KG4, and some for the "Sidewinder" and that is NOT enough. BUY PROPS OR LOOK AT THE TAILS OF EVERYONE ELSE!

I have a Ron Hill Pitch Gage. Does anybody have a John Meyers and would they show a picture of it? I may be interested in buying one if it is superior to Hills.

David; -I have a guage similar to the one closest to the drill press,
not exactly like that one, but close. I have some questions;

-at what diameter do you measure the pitch?
The scale on mine has 12" scribed in at 45deg, which is only true at a diameter of 1.92". Maybe close for a 7" prop, but what is the accepted protocol ?

-my scale is linear, from 6" to 18",
ie; 6" at 22.5 deg
12" at 45deg
18" at 67.5deg.
High school trig tells me that pitch, ie; rise over run,
is a function of the tangent of the angle,
so the scale should not be linear.
Are your scales linear, and at what diameter does it indicate true pitch?
