Tutorial: Plastic rail gun.
Click on the pictures for a larger image.
Tools: X-acto knife, hobby saw and miter box, clippers, files, glue, ruler, pencil, pin vice, wire
Materials: fusion blaster, flamer, burst cannon, crisis suit head antennas (or any other Tau antenna you want to use)
Styrene (aka plasticard) strips
.080 x .0125
.030 x .080
.020 x .125
I use styrene from Evergreen Scale Models (evergreenscalemodels.com)
First I cut apart the weapons to get the parts I would need. From the fusion blaster remove the cylinder and emitter ends and cut the muzzle from the main body of the gun. Remove the ammo drum from the burst cannon, and the fuel tank and button from the flamer. Lastly cut off the antenna where it mounts to the head.
Here are the stock parts we will be using to assemble the rail gun.
To make the rails, cut two 1” long pieces of .080 x .125 styrene.
I then drilled holes in the rails, body and muzzle of the fusion blaster to pin them together for extra strength.
I marked a line ¼” from behind the muzzle for the rail support.
I used the .020 x .125 styrene strip to make a ring around the two rails. I started with the vertical strip using the lines I marked as a guide. The two short horizontal strips were next, then trimmed to allow the final vertical strip to be glued in place. I then trimmed any excess material and used a file to round off the corners to match the body and muzzle.
I then took the .020 x .125 styrene strip and cut two pieces 1/8” long and two pieces 1/16” long. The pieces were glued on the sides of the rails for extra detail. The 1/8” pieces in front of the gun body and the 1/16” pieces behind the muzzle.
I cut two 3/8” pieces of .020 x.125 styrene and drew some designs on them. I then cut out the design with my X-acto knife and used a file to clean the edges.
These details were then glued to the sides of the rail gun connecting the body and rails together.
The reversed side.
To make the new emitter, I cut the .030 x .080 styrene into four 1/8” long pieces. I glued them together and made a rectangular box. I clipped off the excess and glued it to the muzzle. I then used a file to round off the corners.
I removed the peg from the bottom of the gun body and added a strip of .030 x .080 styrene. The cylinder from the fusion blaster and button from the flamer was assembled and attached to the bottom of the gun. If you wish to mount the rail gun on the Broadside’s shoulder, skip this step.
I then pinned and glued the flamer fuel tank to the rear of the gun body.
To mount the ammo drum, remove the peg on the opposite side of where the rail gun is to be mounted. The ammo drum was pinned and glued in place.
The antenna is the last part to be glued in place. I did not have a drill bit small enough for pinning, so the antenna was just glued in place.
Here is the completed rail gun.
Here are some pictures of the first set of rail guns I built.
Thanks for taking the time to read my tutorial. I hope it is helpful in building this version of the rail gun, or even inspires someone to build a variant.
