Monica: Should the collar be split on both sides as in 3_Inch_Wheel_Hub?
Monday June 17, 2013
First came the 0,5" keyway in the hub
Then came the disks, with an external diameter of 2' and a thickness of 0,5".
Then came the angles (2"x2"x1/4") and their attachment to the pipe of the wheel (a 1,75"x1,75"x4" solid with a 3/4" hole and two 0,5" side holes)
So the wheel now looks like this
And here is the updated file. I'm not familiar with dimensions after making groups and all that. I'm lacking of bolts too. Here is the file. File:Wheel-0617.skp

Started building the wheel hub and disks to structure the wheel. The exterior disk of the hub is 12" and the smaller is 6". The hole, as expected is 3".
All the parts are in the same file. File:Wheel-0616.skp
The wheel itself has a 3 Inch Wheel Hub but no bearing. Bearings are part of wheel units in Cory Log for use in Bulldozer and Trucktor. .

Found a STEP CAD file of the FYR 3 SKF bearing that could be used.
Note: It can be expensive. Or, it could be cheap: [1]
I've been trying to import it too sketchup (in the right scale xD) without success. I'll continue in the morning.

Monica has started on the large steel tractor wheel File:Wheel.skp
I think that 2 bolts (1/2") can be enough for the connection of the tracks. The thread could be inside the track or may be a parker bolt should be a better choice. I used a 40" pipe Sch XS (0,5" thickness) for the exterior of the wheel. Rubber should be put between that and the tracks.
