Relby K23 blaster conversion kit
Aluminium conversion kit for the Cloud city blaster, the Relby k-23! the Nemrod Galeon is not included and you'll need to source your own!
The parts are based on a very carefull study and 3D model with perspective match on several references of the screen-used blasters done by Peter Savin "Pedro" and myself as well as precise measurements from the vintage V8 engine parts kindly provided by Cantina Dude. Every little detail, uneven spacing and rings on the muzzle, filet radiuses, have been reproduced as faithfully as possible!
After the back of the speargun is removed, the (blue) barrel tube should be cut flush in the back and at a max length of 13.8cm in the front.
The kit itself is very easy to assemble, I have cut the bolt on the front of the threaded rod shorter (inside) as this blaster is a bit front heavy by detault. Take the end of the threaded rod that is longer, slide the cone part on the bolt and thread the washer to the bolt, they will stop at a proper depth with some threads visible in the back. Insert that assembly into the barrel from the back of the gun. Dry fit together the two gears and the barrel and slide them on the speargun's cut barrel. Then, just thread the muzzle to secure everything together. Make sure to align all the parts to your liking when the assembly is almost tightened. The front sight needs to be glued on the barrel in the appropiate flat spot milled in the front.
There might be a chance that you got a really weird variation with a slightly larger barrel tube, in this case, the gears might not fit on it, no worries, the kit will still work perfectly if you cut the front barrel completely!
In the hypothetical case that you have a thinner barrel, the muzzle base might not fit inside your barrel tube, you can cut the barrel a bit shorter in a way it can still be used to guide the back gear and a portion of the front gear, do not cut it completely if the gears fit around the original barrel.
The variation "No V8 cone" doesn't include the large back cone part so you can use instead your vintage visible V8 engine kit plastic part. The back washer is still included to thread on the main threaded rod. Please be aware you'll need to drill a 13mm or 1/2" hole in your V8 cone to accomodate for the washer part.
