*Dremel with various attachments and Accessories
Sandpaper various girts
* I bought my Dremel over a year ago and I have been looking for any excuse to use it. After this project I highly recommend it to anyone. The accessories that came with my Dremel allowed me to many aspects of the project.
Step 3: Size and Dimensions
See chart for PVC sizes.
As you can see there is no pipe with the appropriate OD*. My solution to this was use 2"" PVC pipe and add a series of 2'' slip couplers/ Doing this I was able to increase the OD from ## to 2.875'' which is an acceptable first try for me.
I need to grid away the inner ring of the couplers in order to allow them to slip freely over the 2'' pipe.
*2.5 is not common size sold in most hardware stores.
The rail cradles were made from one 4'' coupler. The coupler length is reduced to 2.5'' with a chop saw and then cut in half with a Dremel cut off tool. The edges of the of the cradles are then taped from 2.5'' to 1.5''. A 1/4 notch is cut out of the rail and the cradles are are glued in place. Bondo was later used to fill in the cracks and smooth the surface.
When the dried I used the Dremel and sanded the surface smooth and flush.
Use Clear plastic tubing and fill the inside with orange and red LEDs. I would paint the tubing with a transparent orange. Then when triggered the LED's would light up and simulate a glow heat from the coils. The radius of the coils was too small I had trouble getting the coils to retain their shape so I moved to method 2.
I found some copper refrigeration coil form Home Depot. I did a little mental math and found I needed approximately 10ft.
The refrigeration coil is soft enough that it can be shaped by hand with relative ease. It will retain its shape and my opinion looks awesome. It's like a giant copper spring.
The coil starts precoiled in the box. I took the coil and slowly decreased the radius by wrapping it around the 3'' PVC pipe. At this point make sure to twist the coil in the correct direction. Once a 3.5 diameter coil is obtained you can then start to space out the distance between the coils.
Using a Dremel I cut off the curved end of the cap. I believe there are four slots but there could be three. Each slot is 3/4'' wide and 1 1/2 from edge. Using a Dremel I slotted a square hole to slip the 2'' screw end cap.
I created walls for the slots using 1/8'' plywood. I purposely cut them oversize so that I could sand them to size later.
I did some basic stenciling to the fabric to simulate copper etching.
The "leathe'' pieces were attached using 1/4' long screws and finishing washers.
This is was one of my first times using the plastic so I will make this suggestion to you. Cut several small pieces and try heating the pieces by several different methods; boiling, baking and heat gun. I like using a heat gun because I am able to focus the heat by moving the gun back and forth.
In order to shape the top cover of the gun I heated the plastic and molded it over a Nesquik canister. The diameter of the curve is 5''.
I then spray painted the entire gun with a gray steel spray paint. Looking at the color now, I would probably choose a brighter color, either a silver or light gray.
The handle grip was made with another scrape piece of pine. At the time I did not have a working lathe so I attempted to shape it with a hand sander. I plan on fixing this piece in the future when my lathe is repaired. It should be a round handle with a 1.25 diameter.
Step 13: Future Changes/General Comments
After I change a few details I would like to create a military shipping crate complete with the Fink Industries stenciling. I also found a cigar box that it very similar to the size and shape of the RPG ammo box.
I will be adding additional dimensions in the coming days please leave comments where you would like additional details and photos and I will try to accommodate.
I look forward to hearing all comments and idea suggestions. Thanks for reading and happy building.
