Edit: Whoops I wanted to post this in the war machines. Mods, can you move it please?
Hello people, I am new to this forum and sieging since .03 and I made a very small and light bomb throwing system I call the SPG (Sling Propelled Grenade).
I won't go too much into detail and just let pictures speak mainly. You can also find the .bsg on the bottom.
This is a cross-section through the launcher. It is fairly simple, just wooden beams on top and bottom, braced for extra stability and held together by braces running from top to bottom on front and end. On the top of the "barrel" I put braces as direction finders (not really suited for rangefinding and proper aiming). Bottom uses powered wheels in the tank steering configuration with some armor plates, just because. Note that the front wheels are mounted on a toggleable piston in order to raise the thing for extra range.
The most important parts are probably the sling and the projectile itself.
First, the sling. As pusher I use a .20 weight that is attached to toggleable elasticity 10 strings. They run as follows: Two from each side of the foremost block to the sides of the weight, two from the front of the block to the sides of weight, two from the inside of the block to each side and one from the contrarian side of the foremost block to the top and bottom of the weight in order to prevent rolling and spazzing.
Now, for the projectile - I should mention that this thing started as a simple ballista, but the blocks always stuck everywhere and made the whole thing extremely unreliable. Also, exploding things are better than just pointy things (until we get real kinetic projectiles). Anyways, at first I had this simple wood-grabber-bomb setup, but it would stick too much and also break by the sheer force of the springs. When I substituted by weights, I found that they also tend to stick. Then I just decided to try it with the flamethrower and voilà - the only critical point now is the weight, but not so much that it would matter noticeably. Also, I can simulate a rocket if I want ;P
Next up, auxilliaries. The barrel for example. For one, it prevents too much movement and jerking of the projectile and pusher during vehicle movement, on the other hand it leads both straight through the tube. Downside, though, is that the pusher weight and the projectile weight sometimes stick to the plating. However, removing the panels you can't see anymore in the picture, I found that I eliminated the worst offenders. Of course the closed look looks nice immo, but if I get better performance, I can live with that.
Next thing is the grabber in the back. It also looks immensely ugly, but I found it to be necessary - during vehicle movement, the pusher was STILL - despite being "held" already by the panels - jerked around and as soon as it is not 100% right angular to its surroundings, range is affected substantially. So, I put a grabber to hold it in place. Well, I pretend it's a safety
The controls are standard controls, except that I put the bomb grabber on 1 or something to prevent bomb release
That is basically all there is to say to this construct.
I am also working on a version that also secures the projectile, as it also tends to get jerked around during movement, but grabber placement has been either ugly or unfavourable and I can't think of anything without making the whole contruct much heavier and bigger, so I have to live with it like it is.
Also, I attached a .webm, I hope it works.
