Well that blows after several trials and taking up backlash and so on it comes out to about 29.5 turns to get from a 90 degree angle to a 45 degree angle on the saw blade.
Not even for sure it is exactly that.
Too darn bad it isn't a complete 30 turns that would have been easy as 45 divided by 30 is 1.5 on the 10 thread per inch lead screw.
Instead it is 1.5254.
Here is the deal the height adjustment on the saw has a worm wheel and a worm drive.
The pitch on the worm drive has to be .100.
To do this with an angle inside the saw with the adjusting rod and nut you could go about it in several ways.
One, make the distance from the pivot to the nut a wee bit closer.
This would be very hard as any deviation in tolerance would toss it out the window.
Two, make the tread pitch correct.
Again any deviation in the pitch or lead would add up at every turn it would have to be exact and adjustable to zero it in.
Three, make another worm drive and worm wheel or a reduction gear and pinion.
Total redesign of the saw.
Four, make the dial and a chart showing the reading converted to the angle.
Too much trouble for the return.
Five and what I use is very accurate angle gauge blocks.
I tried the digital magnet thing and the tolerances were worse than my blocks.
