Guide rail problem

[aficionado64]

Every time I cut with my rail guide, the blade eats a small amount of rubber from the edge, making the cuts inaccurate.
Is this normal? If not, what could be causing this problem?

Did a search on blade wobble and found this.

Hi,

       Couple questions-  Which saw 55 or 75?

                                      Which blade are you using?

                                      Are you plunging into the cut? or plunging then pushing the saw forward?

       One thing to check-  make sure the saw is adjusted for as snug a fit as possible to the rail with out making it hard to push.  You want to have zero play with out being tight. If the saw has any side to side play on the rail it will eat bits out of the strip until it has removed the width of the play along the entire rail.    
  I am refering to the round green adjustment knobs in the saw base along the channel that rides the rail rib.

     This could also be a toe in /out problem. Are the cuts smooth or do you get a lot of blade marks?

I have a 75, the blade I am using is a W52.
I am plunging into the cut, but also shaves the splinterguard all along the rail.
My cuts are smooth.

Approximately how many cuts have you made?

As Seth asked, does the saw have any side play?

 

[aficionado64]

I does not have any side play, the problem started when I replaced the blade that comes standard for the W52. I put back the original but it keeps doing the same thing.
As far as the number of cuts, I've say a lot.

Smooth cuts but cutting the guide rail rubber strip, right?

If I understand you correctly, you started with the universal blade which has a 2.4 mm width and replaced it with a 52 tooth blade which has a 2.4mm width and then changed back to the universal 36 tooth and now it's cutting the strip.

Have you had to replace the rubber strip since you say you have made a lot of cuts and they have all been cutting the rubber strip?

Does it cut the rubber strip all the way from the beginning of the cut to the end of the cut?

Are you raising the saw at the end of the cut before the blade stops? This will sometimes cause the rubber strip to be cut depending on the side pressure applied.

Is the rubber strip still on the kerf all the way after you make a cut?

Any way to post pictures?

I've just changed my rubber strip about two weeks ago. Still is doing the same thing and now the new strip is ruined.
As for the blade, it is doing it with both 36 and 52.

If one blade is wobbling it usually means a bad blade.
If two blades are wobbling you have to suspect the saw in one of two areas
(especially if a blade that was working fine no longer is).
Either the jibs are out of adjustment and the saw isn't tracking straight, or,
there is something keeping the blade from mounting square on the arbor.

Michael,

The strange part of this he says he is getting smooth cuts. If he has wobble how would the cut be smooth?

Also you didn't answer all of my questions. Can't help if you don't.

Les,
the strip loss is not uniform, in some portions is eaten more than others.
I raise the saw with the blade still running, but now that you mention this, I have not pay attention when I start the cut if I start, then cut or I start cutting.
After the cut the rubber strip losses about 1/64 of an inch from the kerf.

 

[Michael Kellough]

I missed that Les.

I'm beginning to wonder if this is a new guide rail and the recent cuts have been longer than before and therefore cutting into previously uncut sections of the rubber strip?

Hi all,
I just found this thread in a search as I am having the same issue. I recently posted a topic "Suddenly having a problem squaring up sheet goods". The problem it turns out is that my guide rail rubber strip is all notched up where my blade plunges into and exits out of the material. WHen setting my rail "on the mark" it's impossible to now know exactly where to accurately place the rail.
Yesterday I bought the new clear rubber guide rail strips and trimmed them to my TS55 perfectly. My TS has #491952 48 tooth installed. Gibs are snug to guide rail with zero side play but not to snug. Rails are dead straight. I used one of the new rails last night and it is trashed, see pictures.

What I'm noticing in the TS is a small amount of flex when you grip the handle and just lightly twist (kind of unavoidable in the normal use of the saw) especially during the plunge and exit of a cut.

Not sure how to address this but take a look at you rubber strips on your guide rails, I'll guarantee most if not all display this. [sad]
