The angle of the of the blade to the table ( YOUR CHOICE) based on what your trying to accomplish ! That is the key ,( table to blade angle !) I used a mechanical angle finder contacted both the table and the blade ,hard to read (alot of set and reset -read reset ) till your chosen angle was reached ,I just bought a magnetic Johnson angle finder with a nice easy to read dial ! $10.00
happy only for a minute ,that mistic something is wrong feeling creap in my head (as you get older ,you listen to those better )
the old way was always right ,why was this different ? DUH ! So ,I checked the blade to table angle with my small machinest sq. tightenen her down and found the magnetic angle finder on the table in front of the blade was minus 1 1/2 degrees left of center , Which ment the saw is not completely level . Lesson learned (If your saw is not level side to side exactly ) a table angle finder will mislead you ,my saw is not off but a fraction ,but,still will make a big difference if you are going to press fit raises and lowering like I do ,those of you who remember geonometry know about what effect it will have . surest way is to continue the old method does not care if the saw is dead level,and use the new one after saw is really level acording to the angle finder ,with the blade and table sq. to each other ! Mine is mounted on non adjustable hard rubber feet on house floor , I can not
Imagine how far off a concrete poured floor is. If you don't tilt your table (NO WORRIES) if you do ,well you know the rest !
Great Idea ,just not well thought through .But I learned something ,and I guess that is progress! Sheesh!
