Tool Wanted Speedmaster Charts for Pitch Gauge

[Grimracer]

Looking for the charts for a speed master gauge

Thanks

 

[Terry Keeley]

Indicator movement x 360 / # degrees = pitch

My "standard" is to measure 15* of the LE and 15* of the TE at 75% from the C/L.

For example the LE on some 1667's I just checked was:

0.180" x 360 / 15 = 4.32"

I've found that LE pitch will tell you pretty close what speed the prop is capable of, with zero slip it's:

pitch in inches x rpm / 1057

For that 1667 it's: 4.32 x 24,000 / 1057 = 98.1 mph. If you have a clean running boat 15% slip works well so 98.1 x 0.85 = 83 mph.

I checked this audio tach app with the data logger on my SAW boat and it's surprisingly accurate: Engine RPM

My 90 boat with the above prop ran 82 in this vid with the Sky RC GPS. TMI!

I use a WOODs gauge.. BUT picked this Speedmaster in a buyout.. if the Speedmaster came with charts it would be good to get a set back with this gauge.

Thanks for posting TK.. your info is invaluable to us all!

Hey Mike,
Sorry for the late response. I have a Speedmaster gauge. I can text chart to you if you still need one,

I'm sure he does, Richard. Adds value to the gauge he has...
He must be busy to not have replied by now.

Hey Ken,
If I get a chance later today I will post them here. Otherwise I will bring a set to the Wine Run.

Hi Richard Sorry to bother you with this but I wanted to see if you might still have a way to send me or post the speed master charts ?. Grim is sending me a speed master prop gauge and I would like to have the charts .Its been a while and he mentioned that he only had the gauge. Thanks Dave

Happy to help. Going to be out of town for a few days. Will fire it off to you next Wednesday.

Just a curiosity thing, what is the difference between the Woods and the Speedmaster gauge system?

 

[Mike Hughes]

Nothing Don. They both measure the same way. I think the step measurement are even done the same. 1/8" The one Mark and I have use a 1/8 and 1/4 spacer. Still wish I knew where my went. Mark borrowed my rotary table years ago to make himself a pitch gauge after he seen the one Andy B was using. Andys was a hughey on a larger handle. When Mark return the rotary table he handed me one he made for me. I thought it was a good trade.

The Woods gage is like the old Hughey unit, move a certain distance down the blade and measure the degrees of rotation it takes to do it.

The Orlic gage (Speedmaster) rotates the blade a certain number of degrees and an indicator measures the distance the blade would advance (pitch).

Again, I wrote an article on this.

Would you be able to also post the part 3 of the modifying existing propeller designs?

 

[LohringMiller]

Sure, Here are part 1 and 3:
