Default Rigid Miter Saw Fence not straight

Imagine a very shallow "V". I noticed while cutting some 2 x 2's.
Put a straight edge on it and the inner portion of both sides is about
1/8 inch back from the straight edge. So far I haven't found the
manual, but the whole fence is one piece of cast aluminum and I can't
imagine straightening it. Any ideas? I tried wedging the center
portion forward but it lives up to it's name. It is extremely ridgid.

Is it effecting your cut accuracy?

If you can't address the bow in the fence by milling, you might try
shimming the valleys with polypropylene shims; or mount an auxiliary
wooden fence for those critical cuts, similar to when you use a miter
saw for cutting crown molding:

What you lose in cutting depth and width, you may gain in accuracy.

Sub-fence? It'll cost some cut length but it's better than diagonal
cuts.

I once had a cast iron jointer fence with a similar problem. The maker
(Jet) said take it off, put it on a concrete floor/sidewalk, and stand on
the hump. It wouldn't move at first, but the I'd feel it relax. I tried
it and it worked.

I have no idea if it would work for an aluminum fence.

I think the risk is making it worse than it already is. A concave
fence is better than convex.

My Kobalt SCMS fence has done the same thing. It's maybe not as extreme,
but still quite noticeable. At one time, I had replaced the fence with
wood, but since the fence was held together with only a 3/4x3/4 piece of
material it was just a matter of time before things shifted.

I've heard of angle aluminum or steel being used as a fence, but on my
saw at least the original fence was held in place by only 3 bolts.
Trying to mount a metal fence would mean drilling and tapping a new
mounting hole or two in just the right spot to not impede the movement of
the saw.

I'm mulling over a two-part strip of wood which is thicker at the
center and glued over the old fence. I think I can do this with my
planer. The original fence is hollow and two thin for milling. I
found the paperwork and found that this was a reconditioned saw and is
no longer in warranty, so it is up to me to fix it or take a chance on
a new one.

Is the fence aluminum? If it is, this sounds like a perfect job for a
jointer, set for a very light cut. I would cut from the middle outwards,
from both ends, until it does not remove anything, then perhaps one complete
pass set for very light removal.

It IS aluminum, but the fence is off by a hair over 1/8 inch in the
center and the facing on the fence is a hair UNDER 1/8" thick. But I
can glue 1/4 inch wood on it and joint that til it is flat. Thanks
for the suggestion.

I had the problem with my Bosch saw. They replaced the fence with no questions asked. I just recycled the old one.

If you can live with it, I would take Karl's solution. I say live with it as you will need to square up the fence every session that you use it. Maybe not a big deal. Back in the bad old days, my first "powered" miter box had a cast iron fence with milled face. When it worked itself out of square, I took the fence off and filed out the inside of the mounting hole (with a rat tail file) on the fence enough to bring the fence back into square.

If I recall, the machine bolt holding the fence in place about 1/4". I drilled out the holes to a larger size and put large washers with split lock washers on both sides and tightened it up. It worked well.

Now, I would probably go online and look for a fence.

In no way, ever, would cut down a piece of METAL on my jointer. You can cut aluminum on your miter saw as you have a large fence and a relatively small cut surface that is mechanically pushed against a backstop. Hand holding a piece of metal by hand, making a 4" wide cut on a metal of unknown hardness is just nuts. Or worse. Extra sharp blades could easily grab the metal ruin the fence or rip it out of your hands. Duller blades could probably cause enough chatter to ruin the face of the fence.

A 4" wide grab from a sharp bladed fast moving machinery sure sounds exciting to me. There is no way you can "carefully" cut metal using "small cuts" and all that other business. Dangerous isn't mitigated very much by spending more time doing a dumb thing more slowly.

Anyone actually try cutting the aluminum fence this on their own jointer?

Love to see a pic...

Robert

It wouldn't cost that much to just take it to a machine shop and have them
heliarc the low spots and mill the entire surface dead flat. It won't move
with the seasons, and it's good to go.

I can't imagine it being cheaper to have a machine shop involved rather than to just buy it outright, have it shipped to your house, and bolt the new one on. I found several sources online that will sell a new fence assembly for many different Ridgid 10" models for $50-$55 (like ereplacementparts.com), some charge shipping some are free.

On one ebay from a tool supply store, they were $55 for the fence with free shipping.

If I was building decks with the saw, I would get it close with some kind of home built jury rig and let it go. If I was using it for trim work, I would want it to be as perfect as possible. Think just how badly your corners would look even if the saw was off 1/32" after cobbling together a repair. Match up a small molding corners and you could easily have 1/16" open (about the width of pencil line) and worse as the molding gets wider.

No molding or fancy use for me. Can't remember when I ever took it
off 90 deg. Mainly a cut-off saw. What made me suspicious was that
recently cutting short pieces of 2 x 2 (about 4 inches long) the
cutoff would go "bang". That led to finding the reason.

I found an old drawer side in my junk box, ripped and cut it and glued
two pieces on the face of the fence with epoxy. Clamped overnight.
This morning I ran it over the jointer taking small cuts until it was
flat.
After putting the fence back on the saw I checked that it was square
with the blade. Also had to adjust the verticality of the blade.
Re cut a bit off the blocks I had previously made and checked with a
machinist's square. Both ways they were as square as a South Georgia
farm boy.

Thanks for all the suggestions, and especially to Jim in NC for
reminding me what a jointer is for.

Good to hear, but now I've got to try it. You wouldn't happen to have
the other drawer side, would you? *g* (There should be a usable piece of
lumber around here somewhere... ;-))

If you are going to answer an old post, consider also posting what you

Or do it the right way. Have it milled flat.

For not much more than the cost of a couple of cups of coffee for the
supervisor and the machinist that did the work, I got the fence for my
Delta miter saw milled perfectly flat at a local machine shop.
