Hi all thought I would share this - its the list of my jig settings for all my tools on peoples comments around jig setting vs actual angle - see the two columns - DEG (which is the figure set on the proset) and the ACTUAL ANGLE which is the measured angle on the tip of the tool My most fav tool is the number 4 - the settings make it a perfect tool for hocking off the out sides of bowls and then giving it a decent finish it works well inside except for the bottom inside - and then tool 7 which is long and strong with a steep angle for getting the inside bottom nice and smooth QUESTION - what settings do other people use Jig Settings.pdf (226.8 KB)

Hi Francis,
That is a very useful chart. I don't have mine documented as neatly, instead I mark the ends of the handles with a sharpie, and I just knock off the heel without measuring it.
But roughly,
Spindle gouges are 45° fingernail except one that is 60° started in V block and just has the corners knocked off on the table, Spindle roughing gouge is 45° corners left on, Bowl gouges tend to be 55° (i.e. 45° on ProSet then used in 3rd hole of long grind jig)they tend to have the heel knocked off but by eye only Except 1 that is 60° done on table with corners knocked off. Plus I now use the table and no jig to make 2 of them (half inch and three/eighth) 40/40 grind as I am enjoying playing with that. Parting tools are all different! Scrapers I used to use 80° still have some at that, but I am more and more going towards negative rake these days. Skews are mostly 15°, though I do have a half inch one that is 20°

Thanks - I have never used a negative scraper - actually I hate scrapers - they promise so much but often leave torn gran
I tend to use (for bowls etc) the gouge over on its side as a scraper with the handle dropped down so that the cutting edge is 45deg to the timber
I;ll take a picture later and post

I agree scrapers are a tool of last resort, I much prefer to cut not scrape, but there are some woods and some angles that just need a scraper. I am mostly convinced on going negative rake as it puts the tool handle in a more natural position for me, giving me more control and reducing the damage done by the act of scraping.
I also use the bowl gouge for shear scraping when required, usually that is when I have rushed an early cut and created ridges for the bevel to bounce on :-(
