No problem. I have a fab shop and that's what I like doing. So if you have any fabrication questions during your build send me a message. I will be re-working mine in the near future so that my stops move vertically instead of swinging. The swinging is just to unstable. Rolling logs and cants can be pretty rough and the stops take a lot of abuse, so they need to be really sturdy. In my experience, the less moving parts the sturdier something is.
If I can't fix it, I don't want it.

I agree completely about the less moving parts. I am planning on having my pivot points at the bottom of the 2x6 main rail so when they are in the up position they have the full 6" rail to rest against on the outside. When they are all the way up they will rest against the back of the bunks supporting it that direction as well.

That should allow the pivot point to be lighter duty hopefully saving me some weight and cost.

oooh. I like the 1/8" idea. You ever find times when you wish they weren't all connected?

Never.  I wish I had five instead of four.  Mine are standard LT40 pivoting backstops.  I don't mind the pivoting action, because they sometimes help me shift an unruly log back and forth on the mill to get it settled better on the toe boards.  It doesn't work all the time, but if I push the log or cant mostly on top of the backstops with the two plane, basically balancing it, where the backstops are supporting a good deal of the weight, and then back the two plane kind of out a little and unloaded, sometimes, not always, I can raise or lower the backstops and as they pivot, they will physically lift and translate whatever is on top of them forward and backward a few inches, just enough for me to get it situated.  Its a pretty hard and stressful move on the backstops, but I watched a Woodmizer Competition Sawyer do it many years ago and I still use the trick.

Putting top rollers on the backstops is a big help when rolling logs.  Also, installing stainless covers or shields to protect fresh wood, especially oak, from contacting bare carbon steel backstops and blue staining is very useful.

When building be sure to have some means of adjustment so that you can keep them 90 with the sawmill bed.

I like the idea of the first log-stop being 1/4" taller than the rest!

That way, if you clear the first one, you know you'll clear the others too!   ;)

I am  still trying to figure out how to make them adjustable. That is my challenge for the next couple of weeks.

The plan this weekend is to get bed tacked together so I can get carriage built

Adjust the rods that the side supports hinge on.

Larry my rails are 2x6x.188 so your setup may work for mine. But I see a major problem with your T-bolts. How do you get to them with a log on there?

Cruiser, Mine are 11" above the bed, I can cut to 12" with no concern about hitting them. They pivot up together with a lever on the front of the mill. With smaller logs you only pivot up as far as you need to hold the log. Mine are not square, a little over 90 degrees, everything is squared from the base anyways and this allows you to move them with the cant clamped. Top of the backstops are angled to ease logs when turning, tried ball bearings didn't really help much. Frank C.

Without having your backdrops squared with the bed, what is your procedure for cutting the 90 face?

Jeff, they are just a smidgen beyond 90 I can get very close by eye. If precision is required I put a level on the vertical face. They are adjustable if I want square. Frank C.
