while tuning my saw I noticed the wings (I think thats what they're called) have close to 1/16 droop. Do I try to shim them or just let it ride? They are cast iron I don't know what else to tell you.If I dont fix it do I set my extension table to the height of the table or the end of the wing?
That is a bit too much of a drop. You want to have the wings even or a few thousanths below the hight of the table. Loosen the attachment bolts and clamp them in the right location. Use a straight edge to check for the right position. When you have it clamped tighten the bolts a bit at a time like putting on a car wheel. That gives you the best chance of having it stay in the right postion.
Now then, you've got the blade straight, the fence figured, and the run out ran off.
Well, sounds to me like we're headed for purrrfection. Roll up them sleeves.
You got about a four foot piece of heavy, straight angle iron around? I mean about 2" by a quarter thick or bigger. Or some other chunky monkey straight edge?
No, NO, No, not your level! Not strong enough.
You want to use the straight Angle to help you get them wings flat across the main table. If you got 2 of them so much the better.
Loosen the mounting bolts a bit, not to much, so the wing is just loosening. Clamp the angle across the saw's table and draw the wing up to it so's it's nice and flat with the outboard side of the main table where the wing mounts. You want that wings inboard edge and the tables outboard edge F L A T with each other. And the wing tight up to the angle thats flat to the main table.
So at this point: the angle is supporting the wing, and flat across the table and clamped at the other wing. Damned hard to write a picture.
OK take up EVENLY on the bolts till just snug so's there isn't any gap at the inboard/outboard wing/table seam at the top. Use a feeler guage to probe the bottom of the crack of this seam. See if there is any appreciable opening there. If the 1/16" is up against the angle iron, there ought to be some down below, maybe not, maybe so. Cut some shim to fit in the gap and up towards where the bolts are if there is and snug the bolts in a little tighter so the shim is captured and evenly torque the bolts up a little on each one till your saticfied there tight, but don't bust them off, and don't break the wing.
Ease off the clamps and see if it's a tad flatter than it was.
You might have to add a smiggen more shim (.001-.002") to get it as flat as the middle of Texas from edge to edge acrossed the wing/table/wing relationship.
Otherwise, make your extension table the same height as the outboard edge of the wing. Ya don't want a bump to fuss your fence over all the time.
Phil calls it co-planer. I belive that's when all is flat everywhichaway. What ever Ya call it, flat is flat and that's where you want to be at. As flat as you can get it. And plumb as well.
Anyway that's most likely what I'd do.
Now the bags under my eyes and my tool shed are a different matter, that's the droop most of us are dealing with. And I'd be happy with that if my darn shoulder didn't hurt and my knees weren't fallin apart. :D
Maybe somebody else can give you a better idea how to deal with your droop than I did. If you shim it, I think I'd use brass shim.
Good luck with it! TLC, just a bit of TLC for a respectable old work horse.
