I have a very old craftsman miter saw. I got it when I was in my early 20s and I’m now 56. I had seen this and other flavors of the idea but recently I picked one up real cheap. It’s the Infinirator or something like that widget for making a old miter or skil type saw a laser saw. Initially I worried if it would work on my saw, but according to the Rockler website it looked like it would work so I got it while it was on sale recently. You can get it cheaper than from Rockler sometimes from amazon but at the moment that was my best option.

This thing fit perfect on my antique saw. After doing the usual rough line ups I normally do now as I pull the blade down I know exactly how much is going to be cut or trimmed.

Where this thing really excels is when I am sneaking up on cuts. In particular I’m putting in a bunch of fluorescent lights and need to fit pieces of scraps up between rafters that vary from cut to cut. It quick and easy now, stick board up an make rough measure and mark which I know will be too big, cut, than sneak a kerf at a time until it fits tight, than make pocket holes.

There are a couple makers of this type of thing, point is if it works on your saw it great. Why spend a couple hundred bucks to upgrade to the new techy stuff when for $10-15 you can make your 25+ year old tool as good or better than them.

My Ridgid saw came with an arbor nut with a laser in it, not adjustable, but once you get used to exactly where the cut will be relative to the laser, it is kind of handy. Would be much better if these could be adjusted!

That kind of what this is, it not the nut, and you can’t adjust it, it replaces the washer the arbor bolt/nut attaches to. The laser slides right down the edge of the blade. This thing is dead on, much better than my old eyes can set by pulling the blade town to a piece of wood with a pencil line on it. Now I can look at where the laser sits on the pencil line and know, the edge of the kerf is right there.

I bought an aftermarket laser, but it didn’t find it nearly as accurate as lowering the blade to my mark, so I gave up on it. I think it could be handing for making quick, rough cuts, but I don’t trust it for precision cuts.

What Charles Said! Same here. Would rather cut to my mark “Eyeballing” it.

I have 2 Newer Tools (DP & Mitre Saw) with Lasers in them. Never use them. Tried to, NOT Accurate! So I gave up.

sorry to hear that guys, maybe it depends on the saw or the phase of the moon, I don’t know. I just know it really is working great on my saw. I can cut right to the edge of a pencil or other line with no problem, or trim a kerf at a time. I could do that before eyeballing it, but the laser makes life so much easier and more accurate, if my eyeballs are off i get a warning before the cut is made.

One of the reasons I put this in was my new drill press has lasers. Love those things. X marks the spot every time. Sorry Rick, maybe you got a bad one and should have done something.

I also got a better circular saw with a laser, It so much easier to rip ply with the laser. Still not perfect but it helps alot. It so easy to get a little off when ripping sheetgoods.

The one on my saw is about double the kerf width away from where the actual cut will be…not terribly useful, unless you’re doing really, really rough cuts on framing lumber. Even then, it’s too far out for me. Bringing the blade down to the pencil line is slow, but accurate: I’ll take accurate every time.

NO! I didn’t get a bad one. I DID do “something”. I don’t use it. You need the Crutch, by all means, knock yourself out!
