Since my last update, I have since painted the gun satin black and have added the hat lights, arcoelectric lights, ciippard, banjos, and everything else you see in the photos:
Adding the fittings, knobs, arcos, etc. didn't take me very long and were pretty straight forward. The most troublesome part of this build has been the extension kit. After referencing several extension systems in the forums, I decided on the following method:
1. I purchased this 4-40 Push Rod off ebay which included all of the attachments used for the extension system.
2. Next I attached the push rod to the barrel using a piece of coat hanger and 2-part epoxy
3. It would have been nice to attach the 3-holed bar to the extension lever outside of the gun but it would have been impossible to install. Everything was assembled inside the gun. This left little room to manage any putty or epoxy on the bar to prevent it from rotating in place. After several unsuccessful (and frustrating) attempts using epoxy and putty to weld the bar to the extension lever, I went big and bought a welding torch. And no... I know absolutely nothing about welding.
My initial thoughts upon attempting the weld was that I was going to completely melt my resin gun down to nothing and unsuccessfully attach the lever. I almost decided to give up entirely on the extension system but at this point it was purely pride motivating me.
3. I put tin foil in-between in-between everything. And by everything, I mean EVERYTHING. From there, I followed all of youtube's instructions regarding welding and after 2 or 3 quick minutes, the lever was attached.
4. I added a high powered magnet to add a "snap" effect. I also replaced the resin lever holder included with TC's kit with the add on included with freekygeeky's extension bar. I arranged it so the lever, upon retraction, wouldn't over retract and potentially break the weld.
5. My next dilemma was deciding how long to keep the push rod. The extension system, from retraction to extension, only allows for an inch and a half extension. If the rod was long, the barrel wouldn't retract as far as I wanted and short, wouldn't extend as far as I wanted. I made the decision to keep the push rod short and settle for an extending barrel that doesn't go as far as I want. It works though!
(**If someone can think of an add on that will allow the barrel to extend further without affecting retraction, let me know)
And that is that! Just waiting on the GBFans light and sound kit to arrive.
