MOC-19476 Twin turret

The Twin Turret is a whole redesign of the LegoTechnic Automatic Turret remotely operated with Power Functions. The similar capturing mechanism has only in the near past been carried out into twin rotary cannons.

The objective was so as to add a twin gun, take away the lengthy clipholder and keep the variety of rounds. The current model doubles the rateof the weapons working out of part stopping additional load on the motor. The computerized reloading mechanism relies on the gun barrel movement driving theshells into the barrel, locking them in place and shifting the following spherical intoposition after firing. Despite of the complexity of the mechanism, the dual gun works surprisingly dependable.

Construction notes:

The whole mechanism is very built-in making the constructing somewhat tough. I added an lxf file with a single cannon that’s minimize into smaller items. Build these items and joint them. This makes the constructing simpler. Correspondingly construct the mirror picture of the second cannon.

The following elements should be thought of throughout development:

1. The capturing mechanism relies on the yellow rubber bands which can be put in like this. Instead steel springs can be utilized which can be put in like this.These are later solely tough to entry. So begin with putting in these.

2. Build the 2 weapons independently. Once finishedinstall the technic axle 11 onto the small gear in a single gun (e.g. the left one). Do this as follows: place the Technic Gear eight on the big Technic Gear 40 and

roll it into place. Remember the precise preliminary geometry of the enamel and particularly the centre cross earlier than the rolling in.

2. The fundamental issue is combining the 2 gunsout of part. Place the 2 weapons in parallel subsequent to one another (the big Technic Gears 40 are certain to have the identical place on each weapons because of the spring load). Then flip the proper one backward in order that the barrel is going through the otherway and the draw back of the gun is going through upward. Install now all of the parts on the technic axle 11, excluding the Technic Gear eight for the proper gun. Now roll the Technic Gear eight on the proper gun in precisely the identical method (I advised you to recollect) into place and push the axle in.

3. Now comes the onerous half: rotate the weapons across the Technic axle 11to align the barrels parallel. You now should squeeze the motor onto the black pins and get the purple connector (for the worm gear axle) in place. Nothing will get broken, though on the restrict of elasticity. The drawback is to stop the technic axle 11 from slipping off the small gear. This would put you again to merchandise 1.

4. In case you need to have distant angle management you should utilize an SBrick and obtain the LXF file for full distant management here.

Good luck and have enjoyable with it.
