I got a couple of Killbros 350 gravity wagons that require new wood sills. Their 3”x6” wood sills are cracked/split around any knots and previous owner(s) have made weld repairs to the horizontal supports, like what you can see in this photo’s left sill, on it’s second support. This photo isn’t my wagon. I did an internet search to see if this is a common problem. Well yes, seems it is very common. Anyway, in an attempt to remedy any future welds, I’m considering repositioning new sills directly under the box’s vertical supports?? My running gears have ample space to adjust bolsters outward to accommodate it. Anyone on here ever move their sills outward on these boxes?

Yes move them as far apart as possible, much more stable that way. You will understand why when you have one tip over unloading very wet grain! Replace the wood beams with metal tubing, it will outlast the box.

Make sure the steering tire has enough room to turn, if not you may want to just move the rear. Also would a wider seal get out to the vertical support? Maybe a 6x6 oak.

Allis Chalmers still exist in my mind and barns

Thanks for reply. Luckily I've never tipped one over, but I do remember that happening to my Dad's wagon when I was a kid. Nobody was hurt. Makes for a mess & not good moods either. I priced some replacement options today. Here's what I found.

Unverferth.com (Killbros) website list replacement steel sills at S.R. price $229. Ends capped, mounting holes drilled, & painted. So that figures at $458/wagon

Local Steel merchant's 3"x6"x3/16"x 24' rectangular tubing @ $10/ft, weighs 10.7lbs/ft~$180/wagon for material, plus welding end caps, drilling holes, & paint.

Local steel merchant's 3'x6'x1/4' x 24' rectanglular tubing @ $13/ft, weighs 13.9lbs/ft~$234/wagon for material, plus welding end caps, drilling holes, & paint.

Menards.com 2"x8"x10' AC2 green pressure treated @ $10.29 each, weighs 4lbs/ft

- It would require 2 2"x8"s sandwiched together to create one 3"x7.25"x9.25" beam~$41.16/wagon, plus minimal sawing & drilling holes.

Thanks for replying & Excellent point. I just measured my wagon's
steer tires (12.5x15s), when fully turned, would clear the wider adjusted sills by 1.5" and by 1" if the running gear's front steer frame oscillates 6" upward for holes/ditch ect. Yes, a 6"x6" (5.5"x5.5" actual dimensions) would extend about 2.25" directly under the vertical supports. Menards 6"x6"x10' AC2 green treated price $30 each~ $60/wagon, weighs 100lbs each.
