You are correct that the table-top pieces are just clipped over the chain. The chain does have extended pins to hold them. And yes I will include the pics *IF* this thing EVER gets designated. Seems like it's taking forever.....
well, i was asking Tom fron Tenn about his, but yours is interesting too and i like the little tidbit about the carrage bolts -
would never have thought of them! I like the black plastic PVC on the wheels too! I thought it was a rubber sleave at first (I may still look for them plumbing sleaves or something like it. I saw one once, but it has high and low spots where the clamps go).
It turned out very nice!
as for the tracks, are those pads just cliped over the ends of the pins in the track links? are those pins just a bit longer than norm?
you going to add those pictures and infor when your tank gets posted and given a number?

Subject: Re: Progress on the Tiger... [TANKS]
Was this question directed at me Chris? Here are some pics of my tracks and wheels (the wheels are still in rough shape, but mounted). The wheels were cut from an old green treated 2x6 I had laying around and I used a router bit in my drill press on the highest RPMs to cut the center groove in the wheels (to mate with the raised section in the middle of the track) and to true the outside dimensions down to the right size. I then used black PVC pipe around the outside edge of the wheels to protect them from damage running over stuff. I am still debating what kind of detail to add to them. The big washers are there so the flanged bearings don't pull through the holes bored in the center of the wheels. Since this tank will have a working suspension, the suspension arms are cut from 1/4x1" aluminum bar with square holes on! ! both the wheel shaft side and the side that attaches to
the hull. I then used carriage bolts as wheel shafts and pivot shafts in the hull. The square part of the carriage bolts works really well in the suspension. The suspension is mearly a carriage bolt with a shaft collar connected to a spring. The shaft coller uses an larger length screw as a lever for the spring to connect to. All of the shafts are 1/2" and the ones used for the suspension have a nylon lined nut holding the shaft collars tight against the bearings. There is almost no lateral play in the suspension this way. Simple but it works well in tests so far. I also attached a pic of the overall hull progress and the mock up of the drive train. Basically both motor compartments will have a seperate fan blowing from the front of the EV Warrior motor to cool the motors. Another fan will be mounted directly above the EV Warrior to suck the hot air out the t! o! p rear of the tank. I built it like a chimney
so that both motors will be completely seperated and hopefully reduce the amount of heat. Those shinny disks you see are actually "disks". They were pulled from old 5 1/4" hard drives and serve to re-inforce the wood that the flanged bearings are mounted in. Eventually they will be liquid nailed and screwed to the wood. Soon, hopefully very soon I can get a test drive done.....
