RE: [TANKS] Re: Finaly, an RC tank
Sure, I will try my best, if my tank working well, a battle in the Mariland is not far that much!! I only got one issue about the law that i did not get the time to check...

Re: [TANKS] New Track Idea
Joshua, Modern MBT seem to have a sigle horn with split road wheels for better weight coverage over the tracks compared to older tanks. My current plan is a light tank which uses track with two horns. Also small lighter tracked vehicles seem to still use a single road wheel and double horn type track. You would need a notch in the centre to take a horn and i guess a hole ffrom side to side for a pin to hold it. Stewart -- -- You are currently subscribed to the "R/C Tank Combat" group.

Re: [TANKS] New Track Idea
Frank, I agree. I was just thinking 50 links kits. If you want two or three kits to make your robot then that works as well. If I can pull this thing off I will pre-sell kits such that I break even with the mold cost. I don't make any money on those kits, but now I own the injection mold. After that I can sell the links online and just let people pick how many they want. Or maybe offer them in increments of 10 links or something. I am hoping to make a product that will let me build tracked vehicles for fun, and help other people do the same. If it funds my other hobbies that would be great too.

Re: [TANKS] New Track Idea
Doug, Thanks for the advise about the injection molding. I agree that a long through hole is a pain but possible if you design around it. That is one of the reasons I liked the overmolding design. You do not have to worry that problem. It also makes a much cheaper mold. I am hoping to use of the shelf pins with grooves for snap rings. But one that fits is a little tricky. That is one of the draw backs of using the roller chain is I need pins that match the rollers. If I designed my own connecting link it would open up the ability to design around a pin. But that would mean custom links, and custom sprockets to drive it. I would prefer to avoid that. If the trade off is designing and fabricating the pins, or the link / sprocket I would pick the pin. They are very simple parts. Also, the quanties that I am thinking about are around 15,000 treads. So that would be 30,000 pins. In that quantities I can't imagine not being able to get the pins as cheap as any of the shelf product I could find. I know that this sounds quite high quantities. I could do less, but the price per part goes up then. 15,000 treads is only 625 feet of track. Or about 300 kits of 2 foot tracks. Anyway, hopefully my works 3d printer is not busy the next few days. I want to print some test parts and do a pilot run of molded parts in rubber. Plastic tracks just don't feel quite right.

Re: [TANKS] New Track Idea
One thing I learned about injection molding is that you can't mold a part with a long hole through it. Even a 1" long hole would need a substantial cone shape to it to provide enough draft to release the part form the mold. It makes sense when you think about how the mold works and the parts are produced. You can use a 'sliding shutoff' technique, but that would produce a part with a lot less strength right where a track link needs it - along the joining pin. - Doug - Original Message - From: dwconn...@comcast.net To: "rctankcombat" Sent: Tuesday, February 10, 2015 3:34:15 PM Subject: Re: [TANKS] New Track Idea One thing I learned about injection molding is that you can't mold a part with a long hole through it.

Re: [TANKS] New Track Idea
Frank, Well the reason I am looking into using roller chain is to allow it to match up with all the standard roller chain sprockets. I would be able to get any standard roller chain sprocket, tensioner or other product designed for roller chain cheaply and easily. You could use the roller chain calculators to determine correct sprocket spacing. Another key reason is that roller chain is mass produced which means that those parts are widely available and cheap. Up to this design the only custom part was the tread. So rather then getting several parts custom made I would only need to get one custom made. The new horn plate is now a new custom part. But the geometry is fairly simple. I would only be a single part mold. If I can use two of those parts back to back to create a center horn, then I could use the same mold. I am looking at being able to make these in small batches myself, but mostly at trying to make them in bulk and sell to hobbyists. I know that you guys are focused on tank replicas and I would like the track to match those goals. But I am hoping that robotic hobbyists could also benefit from this design. So building tanks, tracked robots, RC lawn mowers, bomb disposal robots, and hopefully more. That is a little bit about my thought process that got me to this point. -- -- You are currently subscribed to the "R/C Tank Combat" group.

Re: [TANKS] New Track Idea
Why do you include roller links in the design? Or, in other words, what problems do they solve? Wouldn't it be cheaper and easier to have two pins embedded in each tread as you show in your design and then mold a link that connects two treads together. The link could then be shaped to fit into a molded drive sprocket. You could incorporate as many links as you need along the length of each tread to ensure reliability. Furthermore, one or more of the links could be shaped as guide horns to suit whatever guide horn arrangement is needed for the vehicle (2 horns/1 wheel vs. 1 wheel/2 horns, etc) On 2/10/2015 1:04 AM, Joshua Updyke wrote: So this new design is still similar and still uses standard roller chain. There is a tread that is molded over two pins. These pins replace the pins that are pressed into roller chain. -- -- You are currently subscribed to the "R/C Tank Combat" group.

Re: [TANKS] New Track Idea
Stewart, Do you know one method is preferred over another? Or if one has advantages or disadvantages? I saw that some were on the outside and some are inside. With my design it is not too difficult to put it on the outside. I was trying to think of a way to put it on the inside as well. I was laying in bed thinking about ways to make the track modular and let the end user decide. For example if the track had a split in the middle and could be assembled in different ways. No horns, middle horn, side horns, or even both middle and side if you wanted. Not sure if you would ever want that.
