You asked for it, you got it. Here are all my WIP photos to date, I'll include explanations for what is happening throughout the photos
SO! First I printed out a 1/2 scale version and multiplied everything I measured by 2. The original SAW is 45 inches long so I printed out a version 3 pages long, that was 27.5 inches.
Here you can see my measurements that I traced.
Here I cut out the first piece on ultra-heavy cardboard to give it some stability.
Here I cut out a replica of the first piece to glue them together; I also have my magnum in the background (I may post the finished product of that too). Now I had my starting template.
Drawing the sides of the drum mag. I was about 3 inches off in diameter for this so it isn't to scale... I'm sure no one notices though, it's just a pet peeve of mine.
First circle cut out, I glued a carboard tube to the middle so I could strengthen the mag.
More strengthening
A lot was done in between this photo and the last, sorry. I glued a long, rectangular piece around the middle piece (and thus the middle circular piece around the cardboard tube had to be slightly smaller in diameter so as to accomodate for the extra cardboard being glued around it)
Some details coming together.
I put down sharpie dots for the holes drilled on the front of the saw to be drilled in, at an inch away from each other with a half inch offset between rows.
Here you can see I drilled the holes (albeit with an unfortunate anomaly on the right side).
The other side looks much cleaner, and if you look closely you can see I accidentally drilled an extra hole on the left side. I filled it up with caulk in the end though so in the final product you can't tell.
You can also see me speculating how the barrel will look eventually.
A butt-ton of details I added in were lost from photos as I was so focused I forgot to take pictures
You can probably replicate the details; it's just a ton of layers cut to different shapes.
As for the drum mag, you can see how I added in other details to the outer ring on the backside. I curved the circular shape in to a smaller circle I glued using small strips (they look stupid now but I seal them up). I also attached nails to the top of the mag so that I could insert it into the gun. The hole in the middle of the mag on the backside is where an anchor nail attaches just in front of the trigger housing. Once all the nails are inserted the mag stays put, and can be removed simply by pulling out the anchor nail and then pulling. There are two pilot holes drilled under the upside down "U" shape where the mag goes. You can't see them but the top two nails insert into them snugly.
More details shown
now the FUN part
The barrel! PVC cutting took a SUPER long time, because of all the measurements and such. I'll see if I can measure the exact pieces after I post this and I can give them to you.
You can kind of see how the pieces fit together but I'll show it anyway.
A close up of the pieces.
This is the real barrel as a reference photo.
All barrel pieces glued together, you can figure out where each piece went easily.
The entire thing! I'm close to finished!
I re-purposed my speculative pieces as anchors for the barrel (The previous photo, the barrel was not physically attached. It was just sitting on top, balancing.)
The pieces fit in snugly and I glued them.
I drilled a large and deep pilot hole for the barrel anchor do slip into. This barrel was not going to be falling out if I could help it.
It was so satisfying to see how well it fit
The barrel anchor was coated in glue and slipped into the pilot hole, and now we have our preliminary, unpainted, unsealed model. I was so happy I had gotten this far without giving up.
A quick reference.
I used white silicone caulk to seal up ugly areas and anomalies.
Ok, there's all my WIP! Let me know how it is and if I should show paint WIP as well.
