Have the base/log frame welded up and have been working on the head the last week or so.
The main beam for the head is a 6x6x5/8x103" long.
The shafts and bearings cost just under $2000 and the wheels/etc. will be another $2000.
The rush job at this time is getting 4 apple cannons ready by next weekend, finishing 2 bale sweeps and a short bed livestock carrier.
