Soundemons Gjallarhorn 2 build thread

In addition to my Fusion 12 tempest LCR build, I'm starting the build process for the mighty Gjallarhorn version 2.


Starting this thread way early (for me) I've got the wood, just delivered this morning, but not a single cut done as of yet. I'll be using the UXL18, which is back ordered but I've got a deposit down on it.


Pix to come!

I think we're the demons.

its a re-fold of the original version, with fewer 180 degree turns and a different driver orientation, so that it is more likely to be vertical in its final placement.

Pix to come, but I've finally started making cuts for this build. funniest thing was wandering around my workshop and garage looking for something long enough and straight enough to use for an edge guide or my initial skillsaw cuts. then it hit me - the next piece of BB in line! lmao

a few pics of progress: Basically I found all the cuts looking for the measurement of 22.583". Of course, we cannot get this level of accuracy using a tape measure, this dimension is just the net result of the overall height of the Ghorn minus 2 pieces of 3/4 BB.


The most important thing is that all of these pieces are the EXACT same height, so I used edge guide and skill saw to cut the 5X5 pieces into manageable sections, and then re-cut each piece on the table saw. set up once and cut ALL pieces requiring this measurement.
one pic is of my edge guide, the next is after a pass thru the table saw and the tiny amount of cutoff that I got.

I've made all the simple cuts, now down to the tricky ones. lots of 45 degree angles to cut which is fine, but there are some which are listed at 34.7 degrees, which should be simple, however this measurement is off the opposite angle, meaning I'd have to set my table saw to 55.3 degrees, and the maximum my saw will go is 45 degrees. anyone have advice on how to achieve greater than 45 degree angles?

I might be mistaken as angles are sometimes hard to imagine, but you should be able to flip the piece over (side to side) and cut on the back side at 34.7. When you flip it back over, you will have your desired 55.3 cut.


We want to see more pictures!

Do I have to store them elsewhere, like photobucket in order to insert this way? I've just been uploading from PC. when I do it that way I cant manipulate the address

Heres the cutsheet and a couple of pictures about what I'm talking about on my saw.
flipped on either side laying flat, the angle is still wrong, it is less than 45 degrees. Laying flat the angle has to be 55.3. its almost like I'd have to run the piece vertically thru the saw to get the angle needed, and I cant figure out a safe and repeatable way to do this:

You can't move the wood to the left side of the saw and cut from the left side of the blade?

Is the panel small enough you could build a jig at 55.3 degrees. I'm thinking like a miter sled with the board at the correct angle and the blade at 90 degrees.

Dude, are you made of leprechauns? Cause that was awesome!

From either side with the wood laying flat the angle has to be 55.3. it has to be standing up to make the angle 34.7. (as far as I can figure)

I may have to do this. there are a couple of 34.7 angles called for in this build.

If you make a 34.7 degree cut, the other angle will still be 55.3 degress.

Sometimes you have to move the wood to the left side and rotate the piece 180 degrees.

We're not working off of 90 degree base though. its 180 degree base, a flat piece of wood. so if I set my blade to 34.7 degrees, both sides of the cut will have a 34.7 degree angle, and a 142.6 degree angle.
I included a little diagram to try and help explain my thoughts better. I called the second angle 33 for some reason. I meant 34.7:

If I wanted a 34.7 degree cut, here's what I would do:
