Ipromised to update yo on our tunnel.

A little back ground incase you did not read the original post.

We could not spring for a factory built, so we got some big 10 foot iron rings donated from the power company, the giant ones that holds big wire. We cut out the spokes so we had four big heavy rings. These were too big to put in the standard bike rims and too heavy for the motors we tried. We built a frame out of wood and set the rings on big metal rollers. this tunnel is 2 10 foot sections divided in the middle. We used 4 tread mills (2 would not do it) one with each ring resting on it. It actually runs very smooth. On the 4rth night of running this thing for about 5 hours a night, one of the treamills belt wore out, it split, so we just moved the part of the belt that was good over to where the ring is and it is back uo. The other tradmills appear to be wearing a little as well, so that is the weak link in this plan. We knew it was not perfect, but are hoping it will get us through this season. We are thinking of a way to just take the belts off and maybe put some grip tape or something and put the roller up to the ring.

Awsome.

No matter how different your idea is, someone out there has also though of it lol.

Our problem is the rings are heavey iron. So this last weekend half the tunnel bit the dust, the rubber shreaded beyond repair, so we are running the first half and just hung dummies in the other part, as it is too late in the season to worry about it.

So I guess the plan did not work. We need to find rims bigger the bike rims to hold the rings and hook a motor to that.

On the rim Center rim only as that is the only one that runs the vortex we used friction tape.
