I have been wanting to try this out for some time and was finally able to get the project going. Overall, this is a fairly easy project where the most of the time spent is trying to find the correct measurements for the barrel and bolt based on where you want to put the coupler.
I also really like this setup as you only really need CPVC and a coupler as your only materials.
For tools, I used a dremel, files, scroll saw, hobby saw, and Zap-a-gap.

Either way here are some of the details that I changed in my tinkering.
Bolt assembly:
I added a circle of rubber gasket (or a suitable sized rubber washer) to the base of the bolt assembly. CPVC didn't fit as snug through the plunger tube and this is just to help give it an extra seal. I don't know if it really helps or not (I didn't try it with or without the gasket) but it can't hurt.
Dart Guide:
Sodizzle originally uses a piece of thin wall PVC to help guide darts into the barrel. I ended up using the dart chamber instead. This is the front of the chamber that connects to the barrel to the first wall that slots into the shell. Flip this around and cut it half and you have a guide for the bolt, the dart and have support for the clip as well.
Barrel:
The barrel is glued to the coupler and uses the faux barrel as a spacer so there does not have to be any glue and everything can be shifted or replaced as necessary. Both the bolt and barrel were coned and smoothed so it is easier to feed and push darts.
OOPS:
When determining where to attach the bolt connector for the bolt sled I did not have the plunger rod attached which caused the alignment to be off due to the draw length being different. Here are some of the fixes to that mistake. (Rather than try to remove the connector and re-attach)
Basically the bolt was too far forward which meant everything needed to be shifted and so......
Plunger rod:
I originally thought that the priming draw of the bold sled went all the way to the plunger tube but that is incorrect. It stops before the plunger tube due to the priming indicator and the end of the plunger rod. Removing the priming indicator and some of the plunger rod allowed me to use the extra space to lengthen the draw enough for my setup. Make sure to bevel the end of the plunger rod to allow it to pass under the catch smoothly.
Bolt sled:
Remove the front nubs of the bolt sled to allow the sled to travel further forward.
Coupler:
The faux barrel was cut down to move the coupler forward and a spacer from another barrel was glued to the dart guide.
WAIT:
What I really should have done was just cut down the bolt. (DUH) I removed a small bit from the bolt and presto! I was able to move the barrel assembly back to the original position and loading darts worked great!

Range Tests:
LS + BBB Combo: Average 85'
K18 Single: Average 80'
K18 + BBB Combo: Average 115'
The K18 is slightly easier to prime than a [k26] and it doesn't feel like it will rip everything apart. This is a great spring for the LS.
Thanks to Sodizzle for the original build. This is a fun mod that I'll probably be doing to the rest of my Longshots.
