I showed the track material to the class and a few segments of my Trutrax and they are working on designing the internal grouser design to fit the tires the best way out of several different materials which i will have to fabricate and make a drill jig so they can do the installation of the elements themselves , they have so many ideals none bad ,it makes me proud to mentor such a group of young people ! One day there will be pictures but not yet .

Oh i looked at the spec`s on your bearing and they had too much width at 7/16 ” W the ones i have sourced are only 5/16″ W so they fit using the current standoffs issued in the kit and are clear of the motor plate mounting screws .

Every time i open the chassis i am astounded by the attention to detail and quality of construction of your product right down to how close the cover fits ,i have to line it up just right and give it a little thump and it seats perfectly !
The class i teach did a lot of research before they shelled out the money to buy the kit i bought for them ,needless to say no one was disappointed when they saw what they had picked out .
The class runs the “show ” i only add some tweaks like these bearings and multiple insert plates for mounting the various control iterations that are being worked on and drop in to make it better as they source and add all the other elements that did not come as part of the kit .It is a superbly designed tool to teach with !

I have discovered an excellent hard track material suitable for wheeled bots . The ideal originated with my industrial Land Tamer II 80 Hp 6x6x6 amphibian ,i bought the hard tracks option with it designed to fit the 15″ rim 32″x 11″ 6 ply truck tires .

Recently i was helping a younger man who had bought 1/2 share in an established machine shop .!I was identifying old machine tools he had never encountered before (i have more than 35 years of machine shop experience as a Master Old School machinist )well in going thru all the stuff he had bought i discovered plastic “Table Top conveyor chain” he had widths from 4″ to 12″ wide and he gifted me with a nice long length of the 4″ width which will work Great with my HD Enclosed ATR 4WD 10″ wheel rover i bought as a kit from our forum hosts !
This conveyor chain is available from McMaster&Carr and used/new on Ebay (really cheap) it is a very stout plastic with SS pins holding the segments together (it is industrial production line equipment ) it can easily drilled and tapped for internal tire grousers and eternal cleats made from anything from plastic to bent sheet metal in the same fashion my my 6x6x6 amphibian tracks are made by this company http://www.trutrax.com .

With my ATR a 59″ piece for each side is all that is required so a 10′ section will make a pair of tracks with a spare segment or two left over . You deflate the tires add the tracks over and re inflate until the necessary tension is reached and GO ! So you can see a little prep work and you too can make some really tough hard tracks for your wheeled robot with ease !
