Now for the rear bolt.
I have spent waaay longer time on this build than I could have, but I just have been taking my time and enjoying the build.
Trying to make it a little more accurate here and there. There are of course a lot more that could have been done on this build, that's the beauty of building with resin, it's so easily customizable.
I used the cap from a pen to make an inner bolt basis. The inner diameter of the doopydoos is about 22mm, and the cap is closer to 20mm, so not a really snug fit, but as close as I got without going out and buying something else.
TK8505 works in plastic, so he volunteered to fill the cap with plastic, to make it solid, which was very practial and worked out really well.
Used a small piece of wood which I filed and sanded down to fit into the rail
Then I found a piece of plastic which I layed over the rail/hole and drew and cut out on to make the continuation of the strip on the ejector port
Drilled small holes on the two pieces and installed small pins to hold them securely in place.
I ended up mounting all the pins in the piece of wood, or else I wouldn't be able to insert the pen cap inside the blaster before assembling the pieces together.
Drilled a small hole in the cocking handle and another hole through the piece of wood and into the cap having a long pin going into the cocking handle and well into the other two pieces, so it can really take a beating and be pulled without risk of anything coming loose.
Then I actually superglued the cocking handle deep on the pin, and glued that to the piece of wood. Notice I've also glued on the piece of plastic that's going to resemble the continuation of the strip on the ejector port.
Here's how it looks mounted together
And here it is with the cap inside the blaster and the woodpiece with cockinghandle inserted securely making it a functioning sliding cocking handle with rear bolt.
Now I can actually insert a spring and screw the endcap on, and the spring will push the bolt forward.
