Vertical alignment

 

Has anyone attempted to file or grind the base to bring it square to the blade over the full range of vertical travel? You can't adjust anything at the pivot point on these machines

I made eccentric bushings and a smaller shaft for the pivot on mine years ago. It was not worth the effort and if I had to do it again I believe it would be easier to glue some material to the base and mill it to shape accordingly.

Good luck!

What did you mean by "square to the base" ? Did you mean parallel with the long axis of the bed ? Or blade perpendicular to the bed ? If parallel , you can adjust the squareness of the cut by adjusting the fixed jaw of the vise . If the other , the blade angle is adjusted by rotating the bearing blocks . And there is some adjustment where the pivot arm bolts to the head casting .

Following Rick Sparber's ideas,
it's way easier to make a sine bar to correct the angle of the bed of the vise area rather than milling, filing, or remachining the saw's pivot.

There is a pdf file in the files section of this group written by John Vreede that goes into great detail on a fix for this.
 

Hi
This question is kinds?topical, as a few days ago I was looking at the article and noticed a few errors in it,?so revised it as attached.??

So ,finished setting up my saw today.? Spent a few hours fiddling with it and bugger me, it is cutting perfectly. Happy days!
 

So, even allowing for the fault which I found with the misalignment of the pivot, I was still able to get the saw cutting square. 75mm SHS is about the largest I am cutting, aside from various flat bar. I am more than happy with it now and will move forward with a few mods.
