Just a quick blog post here. Just wanted to show you the new motor cover I built and installed today.

Held closed with Neodym magnets. I love magnets.

Joe,
Your saw is coming together nicely, and it appears you are getting a handle on dust containment/collection.

Nicely done.

That is such a great idea with the magnets Joe. I can guess you can’t wait to start using this saw.

Oh man, I totally forgot to go into detail about making this thing. Talk about basic geometry and trig coming back to bite me in the ass!

Who knew woodworking would get my geometry skills back in use.

Anyone else remember how to find the hypotenuse of a triangle? a^2+b^2=c^2
A=adjacent side
B=opposite side
C=hypotenuse

And remember:
Pythagorean theorem: a2 + b2 = c2.
Sines: sin A = a/c, sin B = b/c.
Cosines: cos A = b/c, cos B = a/c.
Tangents: tan A = a/b, tan B = b/a

Anyways, that was one problem in building this cover. The other was the angles of two corners. One turned out to be 40.9 and the other 49.1.

How did I find that? Alright so the length of long side of the cover is 18.5” long. The length of the back not contacting the saw is 12.5” long. That gives me an opposite side length of 6” and a hypotenuse of about 9.2” and adjacent side of 7”.

tan B=b/a=7/6=.105….
The inverse of that is 49.1 degrees.

So once I know that angle the other is just a matter of cutting that triangle and use the other edge to set the angle of the blade for the other angle. Which is less than 45 degrees and as you know can not be cut on a table saw that only goes to 45 degrees. I had to use a sander to get that angle of 40.9 degrees.

Easy peasy! Not going to lie I had to look it up to get a refresher in trig.

I’ve got 2 doors now. Finished the front cover and the dust collection slope on the inside of the saw.

Think I should paint the wooden parts black to match the saw?
