Thread: changing super tight ts blade!!!!!

OK,
I'll Bite,

What is a TS

[A Lot of things]

I know I'll regret this.

Table Saw???

Is it a Left Hand Thread????

Trade it in on a new one.

yea a table saw, with Left Hand Thread

i tried again just then... so frustrated!!! really want to drill through the bolt!!!

I know this is suggesting a Code violation, but have you looked in the instruction manual - I think this is getting to the stage where you are allowed to look in it (when all else fails....) - there may be a trick mentioned in it.

Also, it might help if you let us know the Make and Model of the TS.

which way are you trying to turn the nut?

I think from memory you have the 2325 TS right?

I am not familiar with that one specifically, but on mine, TS10L, as I stand in front of the saw, the nut is on the right hand side of the blade and to undo the nut you pull the spanner towards you.

My spanner that came with the saw is only relatively thin (4-5mm?) and I have never looked like bending it, or indeed have had to use force.

Be careful with hitting it with a hammer as you could easily bend the arbor and then you are really in trouble.

Brute force doesn't always win out..............(except if you are a boilermaker perhaps?)

my model is mj2325B, yes i have checked the instruction manual. it says to insert lock bar into hole in the saw table and turn saw blade by hand until lock bar engages in saw spindle hole, loosen saw blade spindle arbor nut spanner (L.H. THREAD)

My lock bar, which is like 7mm thick is also bent.

looks like i have to cut the nut and buy a new one

I am not familiar with the saw you have but the rule of thumb is that the nut will slacken in the direction the blade spins. A good fitting spanner is required so if the nut is still not too badly mangled you are still in with a chance. If the nut is too far gone then try multi grips or a stilson spanner. You will then need a replacement nut. Or rather than do more damage to the nut get help from someone familiar with machinery like a mechanic.
Good luck with it

So you've been trying to turn the nut clockwise? A left hand thread nut in the right size may not be as easy to get as you think, I would not be cutting it...

I've had a similar problem with a panel saw, in a joinery I was working. We had a mechaninc come out & he got the nut off by tapping (not too hard) on the end of the arbour while someone else held the spanner, I remember we had a length of pipe to give more leverage.
I also remember using heat to loosen tight nuts, as the nut will expand before the shaft.
Hope this helps

If you are turning it the right way then you are certainly doing it up too tight. The thread is left handed so the spinning of the saw keeps the nut on. Thile finger tight is too loose, but you only need to snug it up with the spanner. It will not come off with the saw running.
