Doesn't look too bad. You probably set a heavy log on there and the metal gave a little at the support point. You might want to reinforce at those points with wood support blocks. I noticed the rails on my LM2000 had splayed out a little on the bottom side, so I added all-thread rods across the bed to reinforce the rails at a low point under each main bunk. Logs are heavy.

I've had this happen on my LM29 also, and I have seen a bit of a dip in the middle of the smaller top rails. I've had some heavy logs on my mill. With the LM29, the top edge of either the small rail or the big rail is where the rollers ride. On the bottom of the lip of the top rail is where the underwheels are held. I have a trailer, and I've found that I can adjust from the trailer to fix the wide rail. I haven't seen one of them bend in the middle, so it is simply loosen the bolts, adjust, tighten the bolts. For the smaller top rail, I adjust them so the lip the underwheels ride on is good, then if there is something sticking up, I file it down. So far, I haven't had low spot in both the wide rail and the smaller rail in the same place, but I guess I could swap rails with one from somewhere else if I needed. The ones at the head, where the log never sits (the head starts from there) would be a good choice.

i had some white oak on the mill making deck boards for a trailer. i think i am going to put more support bolts under each section . so i will have 4 of them threaded plates under each 4 ft section instead of 2. i did tho have to take the saw head off and reline the bed. does norwood sell just the smaller rails separately ?

My mill has holes for the original feet, but with the trailer, I'm not using them. On a couple places, I did take some 5/16" bolts and nyloc nuts and use those to stand off the rail from the trailer rail. Haven't tried it with weight yet, so I don't know if it helped.

You could add some 3/16 x 1" x 6" long under the rail to beef it up. Just a thought.

That's a thought; I need to look at my mill and see how easy that would be. One issue would be how much space I have between the frame and the rail with the existing hole spacing on the places they connect; I may need to ream the holes a bit.

Garrison, maybe notch the plate like a fender washer and just slide it in ?
