I'm working on a design for a pull-type box scraper for my X734 and would like to get some design input for how to attaching the wheel spindles to the 4"x4" square tubing as shown in the picture below. Note: the unit will weight around 500 lbs. Any suggestions would be welcome.
- The spindles cannot extend any further into the tubing as this would cause wheel interference.
- The weld area of the spindle is 1.25" diameter.
- The 4" square tubing is 1/4" wall.
