Tutorial: How To Make Lascannon Barrels

Lascannons are powerful energy weapons, capable of reducing battle tanks to scrap. They are employed by the forces of the Imperium, chaos, and the occasional light-fingered Ork. Today's post is a tutorial on how to make a fairly basic lascannon barrel, including energy coil. It is an ideal design for vehicles and infantry. For this, you will need:

Two pieces of different sized plasticard pipe, one that is big enough to slide over the other
Greenstuff/yellow-blue two part putty
A (clean!) comb, ideally one with very fine teeth
Hobby knife
Poly cement/glue

First, cut your thin pipe to a size you are happy with for the main gun barrel. Cut a short piece of the larger pipe, at an angle on one end. Add glue and slide over the thin pipe, leaving a small tip poking out.

Cut a thin circle from the large pipe, and glue this to the lascannon barrel, somewhere near the middle.

Once fully set, cover the blank end in a layer of greenstuff. Make it no thicker than the large pipe ring from the previous stage. Leave a few millimetres of blank pipe at the end, and smooth the putty with Vaseline and your fingers or a sculpting tool.

Rub a bit of Vaseline on the comb, and start rolling the green stuff-covered pipe over it, apply pressure whilst doing this to create a ribbed cable look.

Allow this to set, clean up the greenstuff, and there you go. A lascannon barrel. At this stage you can add a back section and a power source to the gun, and any details and flourishes of your choosing.


  1. Interesting. May I ask where you get the tube from? I was gonna do some ork weapons but I've had trouble finding adequate plasticard tubes.
    BTW, I love your blog!

    1. Hi there! Thanks for the comments :) I get my tube from Boyes department store, but I think you could get them from most hobby stores. If not, Google "Evergreen scale models", they make the stuff I use :)


  2. To make certain your green stuff diameter is even, you could put a pre measured temporary "sleeve" of the larger diameter tubing on the opposite end of the small circle you glued in place halfway up the barrel. Then just apply green stuff and roll it between the temp sleeve and set in circle like a rolling pin - your "coil" base will be perfectly even. - Michael Fishel
