complimentry angles

All the miter gauges and settings on the miter saws and table saws do NOT give you the actual angle measured with a protractor. Rather they give the compliment of the angle... set your miter gauge to 30 degrees and the actual cut angle will be 60 degrees measured with a protractor. So, zero degrees is really 90 degrees. etc.

So, you must be specific when referring to angles .... actual or complimentry. A draftsman will make drawings using the actual angles. A carpenter will know to invert the numbers for the compliments.

Acute angles are impossible to make without a jig on the table saw or miter saw unless the pieces are very short.

The answer to your question will only be as detailed and specific as the question is detailed and specific. Good questions also include a sketch or a photo that illustrates your issue. (:< D)

Ok so here is what I mean, that is a taper right? What I am looking at is a bevel I believe (could be wrong). now I made a sketchup drawing that is roughly correct (can't seem to get the geometry right as far as hidden interior angles and all that is concerned but that is just my lack of experience with sketchup) but if you could stand the piece up on a miter saw (if you had a GIANT miter saw) then sure, it would be an easy 15 degree from perpendicular cut. But since the piece would be too big and awkward for it you have to lay it down and that makes it a 75ish degree angle to perpendicular. Pictures below.

putting it simply ...

You can draw things in Sketch Up that you can not make on traditional equipment.... maybe on a 5 axis mill, I donno? If you are going to make these things, you have to use the skills and equipment on hand or at least within a budget. They can not be so complex that that are beyond the scope of your skills or your $$$.

I don't see these shapes being cut with traditional woodworking machines, but I could be proven wrong. :frown2:

I mean, the radial saw I found on craigslist looks like it can, it can literally turn 90 degrees (although useless for anything but joints) and I only need like 70 degrees. I am going to look at it tomorrow and probably buy it.

Here's the link again, look closely at the 4th picture, it can rotate 90 degrees in both directions. Theoretically, looking at it, I should be able to tilt that 70 degrees and pull it across the board and make the cut. Am I missing something here?

Oh, I just realized that those pictures do not expand into bigger pictures. how do I insert full sized images in here? Hard to see but I was showing you the angles with the protractor tool.
