So unless you came to woodworking as something to do later in life chances are that most likely you’ve used some sort of portable table saw in the past.

If thats the case then chances are you’ve done all you can do to properly set your fence, but then you cut into the board and realize that as you clamped the fence it came out of parallel from the blade slightly. You push the board through and as you get to the end of the cut you can see that your forcing the blade sideways a little and it takes a little more of the last inch of the piece..

Well right now getting a new saw isn’t an option and it won’t be for some time. And even more of a not option is to spend the extra time to make sure its parallel every time. I could certainly aim to be more precise, but its just not going to happen every cut.

So here was my thought was to make some sort of sacrificial style fence on the backside of the fence which I can then maybe notch a little so that I can attach some plastic framing squares to the underside of. Not sure whether or not this makes sense to you all, but if not maybe I can draw on sketchup tonight what I’m thinking about. I literally just came up with this idea this morning when I was doing where I always do my best thinking.

Anyone else ever do something like this or seen something like this. Figure before I start building it, I’d ask around on here since projects always turn better after they’ve been run through the LJ ringer.

I have the PCB220TS= if that matters at all.

My bosch 4100 uses a similar fence; what I had to do was tighten the locking mechanism so the fence applies more pressure when it’s locked down. That fixed the issue.

Do try to save some pennies for a new saw though. My next saw will be my last.

That might give you some ideas Ben. Doesn’t seem expensive at all. Don’t know if it will work with the saw however, maybe it could be modified? Just an idea. Fought with my old saw day in and day out with getting a square cut, I feel for you

while it’s not a 4510 of a bosch 4100, that saw looks to have what should be a reasonably functional fence. i’d verify the alignment relative to the same miter slot i used when aligning the blade to a miter slot. never assume a tool is seet up accurately direct from the manufacturer. i have a crummy, less than what you have, c-man 10” plastic POS that i use for helping friends onsite and it rips almost as accurately as the t2 i have on a c-man 113 series CI TS.

+1 on checking alignment. Do blade to miter slot first, then fence to blade. Mine is toed out by the thickness of a piece of paper at the back.

I was trying to true up an original fence on my son-in-laws Craftsman saw. It was given to him by his not to mechanically inclined father. My son-in-law is not too mechanically incline either. I fought with that fence for a week. Every time I moved it in or out something seemed to change. On this saw the rails are angle iron. I finally noticed that the fence was clamping tight enough to cause the angle iron to flex. The distance from the nearest standoff dictated the new angle for the angle iron. I did some serious measuring with a micrometer and decided I needed a spacer that was exactly half inch long. Off to the machine shop. I got a space that was half inch thick with the desired hole through the center. I put it in and it stopped the flexing. The fence is accurate and I think it is delivering all one could expect from it. Is something like this the problem?

I think my biggest issue is not settings on the saw but more of it being a design flaw. The front locks great, but I think that its designed for the whole thing to tighten based off the front clamp, but there is a little play on the back side. Essentially I was thinking of something similar to what Kaleb posted, so I figured I’d draw a picture.

Essentially a cap over the fence with couple of speed squares attatched (might be able to eliminate the front one if need be or if its overkill).

I wish I could measure based off my miter slots, but they have a chamfered edge so its almost impossible to get a repeatable measurement on the front and back every time.
