You do some first-class fab word D6c.  What are you using to cut out the parts?

I have a some equipment in the corner of my shop...lathe, bridgeport, drill press, vertical saw, & surface grinder.  It's been king of nice to do a little machine work on this project.  I don't get a chance to keep my skills up like I used to and it's amazing how rusty you get after a while.

Heads up thinking there on the roller placement.I've been sawing a lot of 8' logs and the front toe roller doesn't catch the log.
D6c has that covered by mounting both of his toe boards on the inside.  The rest of us have to remember to always load short (8') logs "butt to the front".   ;D

I'm down to figuring out how I want to modify the side supports....lengthening the arms and adding rollers.
With raising the bed 2" the supports are a little short at about 7 1/4" above the rails.

How tall is WM building them these days?  Any thoughts on how tall I should make them?
I made a couple of slip-in extensions a while back that added 6" so if I use them they'd be around 12 1/4"

 

 


Since the supports are square tubing, I was thinking of adding a single roller on the top instead of the 2-roller arrangement I seen WM using.  Any reason why one roller won't work?

Here's what I had in mind.....
 

 


I've got all the linkage for the side supports and toe boards put together.
 

 
In case it looks like everything has gone exactly to plan...it didn't.  I made a error in measuring the center to center length of the side support cylinder.  Had it about an inch shorter than it actually is, which made the mounting bracket too long.
Not a disaster.....just had to cut an inch or so out of the middle of the bracket and weld it back together.
 

  

  

 
 Squirt a little paint on it and it'll never show.....

They are 11" above the bed to the tip.  Longer would be better but I'm sure you're aware that the ones on your mill aren't built as stout as newer mills, so that should be a consideration when going long.

Thanks....I'll probably stick to about that height.  The adjustment brackets aren't real strong and I may end up having to build heavier ones if I can't keep it in adjustment.
Spent half the afternoon adjusting the side supports.  Kind of a tedious job getting them all straight & square.  Had to weld up the end of one of the pipes to get it to line up with the others.  It had been cut a little short on the end that mounts to the main frame tube.

The pipes that the side supports pivot on look to be just sch. 40 pipe and aren't very round.  It always caused a problem with getting the tension set right.  Too loose in one spot & too tight in another.
I put the supports in the mill and "bored" the outside of the pipe to make them truly round on the end.  MUCH better now....nice even tension all the way up & down.   :)

On my mill, with the sawhead height scale set on 11" the blade will "just" clear the uprights

I'm going to call Phase II of this project complete...(adding toe boards, side stop linkage, and cylinders)
I finished up modifying the side supports and assembled all of the components (at least temporarily)

 

 

Made the side stops about 11" to top of the roller with the front support being just a touch taller than the rest to make it less likely that I'll cut into them....at least not All of them.

 

 

In the 2nd photo you can see I put blocks on the rails so the short stops are in line with the side supports.  I think newer machines are already like this.  It was necessary because the stop on the hydraulic clamp is designed in that position.  I could have modified the hyd. clamp but decided to see if this easier solution works ok.

 

 

Next up will be starting work on the hydraulics.  I've got the pump, 6-section stack valve, & hyd filter.  I need to start designing an enclosure with enough room to house the components and all the hoses etc.  I'm going to leave room for a 7th valve in case I decide to add a log lift later.   I spent part of today sorting out what hydraulic fittings and hose ends I'll need plus got a rough measurement of how much hose it will take.

That is first class fabrication. 

Get a couple of larger pieces of square tubing ~18" long that will slip over your side supports.  Use these when you are turning (too) large logs or logs with irregular flutes.  Slip them on, turn the log, and then remove them.

I dont know why but neither of my mills have the ''cant dogs'' on the inner bed rails. I think they thought they wernt necessary  since the back of the clamp would catch a cant there. However on short logs they would be nice. You may have a ''better than new one'' when you are done.

My thoughts exactly.

No idea why, but I guess they didn't put them on any of the two inner bed rails, just the main two!

I've thought about making a cant dog for each of the inner rails, but that's still "just a thought"!

Would definitely be nice when sawing short stuff!
