The primer is weld thru, so I do not have to clean it off before welding an area again. So far, with the exception of the framework, most parts have been "off the shelf" items. The front drive sprocket axle will be made from 1018 1" round bar with pillow block bearings providing the support. The hubs are go kart live axle drive hubs and the rims are for a trailer.
The rear idler was a little more of a challenge. The hubs and rims are for a trailer. The swing arm is custom made. The spindle is welded in on one end and the swing arms axle is on the other. The whole assembly is supported by two pillow block bearings. Not completed yet is the attachment point on the swing arm axle for a turn buckle. The turn buckle will be used to move and secure the rear idler thereby adjusting track tension. There is some additional support framework needed as well.
Progress so far has been fairly swift and I am significantly ahead of scedule. Next up will be the tracks and sprockets. I have taken most of the winter off from the project. It has been very cold this winter and I just didn't feel like paying out in the cold. :)
Spring is fast apporaching and I am preparing to upgrade/add several items in the garage that will significantly improve/increase my metal fabrication skills. I will no longer be dependant on "off the shelf" items to use for my parts. Till the next time I will give you a look at the full progress. This picture was taken on 09/22/13.
