I’ve installed the other end of the split loom on my gun’s handle, and I thought that I finish my tutorial. Like the first time, this is entirely reversible, so you can remove the loom at will. Also, it’s pretty much specific to metal handles, but can be adapted to PVC handles with minimal effort. So here goes!
First thing first, trim your loom to the desired length. Personally I went with 3 1/2 feet. Then trim your clear tubing to be 6 inches longer (or whichever is necessary to go in the gun box) You should end up with something like this:
PVC tubing 6" longer than the loom. Zip tie optional.
To attach the loom, you need one long bolt, one that’s almost as long as the ID of your handle. I chose a 8/32" cap screw. Then you measure the hole and tap it. Mine is 1 1/8" from the end of the handle, centered onthe bottom (where the grip will be)
Next you drill a big hole (mine is 7/32") in the clear hose. You drill it around where the end of the loom should be. Mine is around 5 3/4" from the end of the hose.
Then you insert the clear tubing in the handle, and align the two holes. It’s easier than it sounds.
Now you screw the bolt all the way, making sure that it clears the hole in the tube. If your hose isn’t split down the side like mine, you can even drill two holes! It’ll be even tougher. 
Don’t forget to dig a little hole for the screw’s head in the grip. The screw will be hidden by the grip. The hole in the grip is 1" from its end (that’s why I drilled the hole 1 1/8" earlier; so that my grip would be 1/8" from the end of the handle)
Voilà! Your split loom is solidly attached to your thrower. My loom goes just a little in the handle, just like the screen-used packs in a lot of screen shots. Of course you can adjust it to your liking.
