table saw binds up with 1/4 inch elevation after 2"
Oh, the headache! I haven't used my table saw for many years, as it was in my son's basement. I recently had my little shop built, and moved it in for added woodworking joy. Its a Sears, 10" saw, on a sturdy stand, covered now with a light rust that will be removed soon. My mystery is that when I elevate the blade at 90* to 2", it works fine, and saws true. When I elevate that blade one fourth inch more, no other adjustments, it groans and clatters for a few turns, binds up, blows the main breaker in the shop, and yanks the arbor nut, (I guess) so hard when it binds up that the nut loosens, and the blade flops freely back and forth so much that it appears that I only started threading the arbor nut! flops crazily! This was with a motor-trial, NOT while sawing, thank GOD. Scared me to near death. (I have a healthy fear of my saw, anyway) So, basically, I needed to through-saw a 2.25 X 3" (full size, home-sawn board) into two 1.5" X 2.25" boards. Since I couldn't get the through-saw width, I finally got it done, by flipping the board a few times...but talk about stress! I even oiled everything I could find that could need oiling, and trued the 90* blade before the first trial of the saw. I DID have to use a little WD40 on the arbor nut to initially bust it free, but wiped it off very well, and it held just fine at 2"- no loosening, even with the cut of the board. It only loosened it when it bound up and flipped the breaker. Can someone please tell me WHY I can't elevate that blade to 2.25" and run the saw without the saw binding up, blowing the breaker, and breaking the blade loose on the arbor? -Oh, and how to fix it maybe? I DID put it together originally many years ago- maybe 15 yrs ago, but without taking the entire thing apart again and putting it ALL back together, I have no idea how to figure it out, and even then I might not. I have maybe only made 2 or 3 dozen cuts with it all told. No experience here. Thank you in advance for the help. (oh, how wonderful it is to have my saw available again- IF I can feel somewhat safe using it!)

Reason: missed a comma and repaired grammar
I am on vacation until November. After that I will be back to woodworking..... Well Kind of. Right Hot Lips? I mean Joanne.
Craftsman, I have one of them I stored. It drove me nuts until I had enough and picked up a Real saw.
It sounds like the motor has to be reversing as the nut should tighten ( always as the motor turns. My guess is check and see if you have the thing wired correctly and not backward reversing the rotation of the motor.
Thank EACH for your replies! Lorax, The table saw is a Craftsman 133.298722/762 series. ...Thank you for the kind 'welcome'!
Jacko, I HEAR ya on the Real saw... However, I am just a Mom/Gramma with a burn to play with wood, and Jobs around the place to get done, and with zip money, so I am stuck with this saw till somebody recognizes my incredible worth as a human being and rewards me for it financially.... still waiting.... I , being the coward that I am, NEED one of those saws that cannot cut you and supposedly stops the blade when it touches flesh....Jacko, I'm COMPLETELY lost: Could the motor be 'reversed and still running the blade correctly? (remember, the thing works fine at 2" blade height, and NOT at 2.25" blade height... It cuts like a dream and the blade stays on tight before I elevate that last quarter inch... Or can the motor be reversed and still run the blade in the proper direction... I am feeling suddenly like I am a helpless mess for not 'getting it'. (and thank you for the "Welcome", too!)
Boxman, I looked up 'trunion' and get: (wikipedia)"In woodworking, they are the assembly that holds a saw's arbor to the underside of the saw table."
Which is logical, but I haven't a CLUE as to how to get to them to LOOK at them! I could barely get the tip of my oiler (30cc syringe w 18 gauge needle -I am an RN) under the table to reach logical oiling points... any ideas on how to get to those things to look at them? IF one is cracked, is there anything I can do to fix it, or does this mean unsafe saw? I DO note that when I elevate the blade, the crank turns easily till after the 2" mark, then it becomes difficult to turn...I almost cannot turn it after the 2.25 mark.
OK, here's one thing to check. Is the motor hitting something when you raise it? Shelf? Table? Reason I ask is I have an outfeed table behind my saw and sometimes the motor hits the table if I forget to pull the saw out.
Hope you stick around, Joann could use an ally.
