So, with Disappointment Depot behind us, let's move onto another Bad Tutorial! Last time, I attempted to teach you how to build a TF2 shotgun. Now I'm going to semi-attempt to tell you how to build your own Pancor Jackhammer. Chances are if you can't build the first one, you sure as hell aren't going to make it far on this one! With the demeaning taunts done (or am I), let's get to the schematic.
For this task, you'll need the following tools:
- Stack of Magic: the Gathering cards (or structural equivalent, Yu-Gi-Oh! cards need not apply.)
- X-Acto knife and a cutting surface, and regular scissors
- 110lb cardstock and regular printer paper
- Sandpaper (coarse grit at a minimum)
- Tweezers (by Yawgmoth almighty, you'll want these badly)
- Elmer's glue (any strength, but not a Glue Stick), and Super Glue of any type
- Paper clips, and preferably a 1/8" diameter rod
- Dial calipers (oh hell yes you need this unless you're a savant)
- This excel spreadsheet from this explanatory post explaining how to make cylinders out of paper
- Guide to building with Magic: the Gathering cards (optional)
- Pliers (recommended unless you're a badass)
- 1/16" hand drill (highly recommended, but completely optional)
From the schematic, you'll need to make a few templates out of cards or 110lb cardstock to trace out sections of the gun. I've drawn some diagrams of how some parts need to be assembled, but you'll have to fill in the gaps. It's like woodworking, or shop class, except my shop class experience was a lot of New Yankee Workshop episodes on PBS and no actual building.
I've fortunately done most of the hard work for you, mapping out all the major components. We'll break down the gun into regions to work on. We have the following zones and sub components:
- Magazine (1x 9mm outer diameter, 2mm inner diameter 110lb cardstock cylinder, 12.5mm long; 10x 3.175mm inner diameter, 4mm outer diameter printer paper cylinders, all 12mm long)
- Grip/receiver (Magic: the Gathering cards, to be documented later))
- Pump (2mm diameter rod, 75mm long, made from a paper clip and covered with a roll of printer paper glued with loc-tite super glue; lots of MtG cards)
- Magazine housing (13mm wide x 32mm long MtG strips glued together to form a 10mm radius half arc; 2x MtG card covers built to schematic specs, 4 cards thick)
- Stock (2x 8mm outer diameter, 3.175 mm inner diameter, 16mm long 110lb cardstock tubes)
- Carrying handle/sights (MtG cards, to be documented later)
- Barrel and muzzle (45mm long, 3.175 inner diameter, 7mm outer diameter tube; compound tube with a 13.5mm long, 8.5mm outer diameter first section; transitioning to a 10mm outer diameter, 3.5mm long second section, uniform 7mm inner diameter throughout; 100lb cardstock)
If you thought that was hard, well, the rest is more of the same. Time to explain the receiver/grip and the pump. For this model, we're going to make the model have a sliding pump to release the magazine like the real one supposedly does. You can skip parts of this if you wish, and it'll make the job obscenely easier. I'll note the options you can skip if you want a static model and describe anyalternate steps in italics.
The pump needs a template too. Of the 9mm tall section, you'll need just 6mm of height, as the center region will mate with the barrel's underside. Do the same as the receiver and cut a 2mm wide groove on the bottom of two 4-card thick sections of the pump. Roll printer paper around a straightened paper clip until you reach a diameter of slightly under 2mm. Glue this rod to the pump groove, and only to the pump groove. Highly suggest using loc-tite or super glue to coat the rod to enhance durability. Make 16 cards thick worth of the center part of the pump, then another 3 card section of the full profile to do the side grips. The additional 3mm will overlap the barrel, and needs to be bent outwards slightly. Tweezers helps a lot with this task.
The Magazine housing.
Didn't take a damn picture, so here's what you're ultimately trying to get:
At this stage, you'll want to make the grooves on the side of the magazine. Make some right triangles with 7mm height and 5.6mm width for the side facing the barrel. Make a series of "L's" 6mm tall and 5.6mm wide for the other side. Printer paper works fine.
Barrel and stock assembly:
Barrel's just two tubes as described earlier, but you'll need to cut the muzzle at a diagonal. Join the muzzle with the barrel and leave 40mm of the barrel in length unobstructed. To attach the barrel to the receiver, go nuts with the super glue or add a 3.175mm diameter rod to the receiver to support the barrel.
For the stock, you'll use two of those 8mm diameter, 16mm long tubes. Flatten the sides of one of them by shaving off material with a sander/knife. Glue the two to the oval looking shape from the stock's drawing. That section needs to be 12 cards thick. Add the little details for the stock at this point. Should be trivial at this stage.
If your gun looks remotely like this, you're doing great! Time to make heat dissipators!
make your own! You now have the most badass 1:6 scale Pancor Jackhammer model money can't buy (or if you built it poorly, the most crappy model ever!).
