Cutting the edges @ angles

[Bones]

anybody know of a tutorial that can show me how to cut the edges of the panels at the correct angles?

I use a circular saw and guide boards. I clamp the guide board and piece to be cut to the work bench and run the along on top of the guide. This works for cuts up to 45 degrees. For cuts larger than 12", I prefer not to use my little table saw.

Not certain if WB answered your question, so I'll throw in my 2 cents.

There are many ways to accomplish this, but here is a simple method that might work for you.

1. Buy the plans and follow the plans. One of the steps is to take one side of the speaker and draw the location of all the joints as show in the plans. This will show you the angles that you need.

2. Borrow or buy one of these: http://www.rd.com/sliding-t-bevel/article12940.html

3. Unlock the T-bevel wing nut or thumb screw and lay it on the plan you drew on the speaker side. Adjust the bevel to match the angle you are wanting to cut and lock it at that angle with the wing nut or thumb screw.

4. Most saws, both table saws and circular saws, have the ability to adjust the angle of the blade. On table saws there is a crank that adjusts the angle of the saw arbor. On a Shopsmith, the blade remains verticle and the table angle is adjusted. On a circular saw, the angle of the base plate is adjustable. On most saws, there are protractor markings to tell you the angle you are setting up, but unless you know how to adjust and calibrate your saw, these markings are notoriously inaccurate.

5. Place one edge of your T-bevel on your table saw table or circular saw base plate, hold the other edge against the blade, and adjust accordingly to get the exact angle that you took from the layout drawing on your speaker side. IMHO, if you did an accurate layout drawing, this method is much more accurate than relying on the saw markings.

6. To actually make the cut, follow WB's advice of using a guide board.

Hope this helps!

Ironically, I'm in the same boat as Jones: my friend and I had a question about the degrees actually printed on the plans. Where pieces are joined on the TT cut degree diagram, we were wondering how to determine the degrees for where pieces join each other. Hopefully it's not so obvious that we missed it but I'd rather build his sub right the first time and be embarrassed=)

Did some recon with a carpenter and he, as is evident in the plans, to draw out the diagram life size and use a protractor to figure out the remaining angles: sounded right to me. . .
