Reverse Roll QS on a manual mill
« on: April 11, 2017, 08:55:06 AM »
Following Yellowhammer's QS method on my manual mill showed me I needed some tools in addition to my cam clamps and squaring arms to stabilize a cant on edge. The pics show what I ended up using.

I use a bottle jack w/ a sharp ring tack welded to the tip to bite into the cant to lift/rotate. Adjustable braces (1/2 - 13 threaded rod) are inserted to counter the sawing force caused by the blade. My squaring arms pivot and so are not very useful to hold the angle without a good bit of force against them.
 

 

 

 


Blocks clamped to the bunks hold the cant and define its pivot point.
 

 


The last piece is pretty small so sawing was done very slowly. I flipped the pieces and sawed off the bottom.
 

 


Tools needed are pretty simple. The scissor jack is used to push cant when needed.
 

 

Sorry, no pics of the lumber - they are stacked for drying.
Thanks again to Yellowhammer.

Now that is digging in and clawing the "goody" out of that log.   smiley_thumbsup

kelLOGg, I read YH's thread explaining this. How interesting!
Is this the first log that you've done this way? Do you plan to continue this method on certain logs?

I have done about 3 logs (6 halves) this way and I plan to continue. It does take more time and there is a learning curve but the last log I did went much faster than the first. (I didn't time it). The little adjustable braces are surprisingly effective at stabilizing the cant during the cut but I am open to using blocks and maybe even the squaring arm; it all depends on the size/shape of the cant. To make sure the braces have bitten into the cant I release the jack letting the cant settle into the brace then reapply the jack pressure just a tad so it make contact with the cant.

 I like it! Simple and useful.

Actually, I was a little disappointed in the ray fleck. I got more in the sapwood than the heart. I think it was due to the log (I know, but really ::)) - the small cracks began to curve as they went thru the heart toward the pith so there was no way a straight line saw path could be perpendicular to the growth rings in both the heart and sapwood. I should have cleaned up an end of a board and taken a pic.
Thanks for the feedback.
