Multi Purpose blade + wood with nails

[cArliTo]

Has anyone here tried an evolution multi purpose blade on their bt3 table saw? I have a bunch of wood with nails that i`d like to rip and use for legs for my rabbit hutches.. now the obvious answer would be "buy better wood" but in this case its a great opportunity to use reclaimed wood for a project that is literally going to rot away.

So, has anyone setup one of these blades and used it for this purpose? And more importantly, has anyone used some other form of blade to do what I want to do? Obviously something cheaper would be cool - but even at $65 I will come out ahead of buying hundreds of 2x4's to serve this purpose.

Here is a link for those not familiar:

I have previously used their 7 1/4" steel circular saw and cut 5/16" plate with it - I have nothing but great things to say about that beast. Sadly its no longer in my posession.

As I understand it, the Evolution blade is only for the Evolution saw. I believe I read somewhere (famous last words) that the Evolution circ saw turns slower than a stock circ saw.

1" arbor hole - won't fit your BT arbor properly. Probably their way of restricting use to the Evolution saw (which I'm not really familiar with).

And besides it says on the label, max speed 2500 RPM. BT3s wants min 5000 RPM rating for their blades.

First thing that hit me was the RPM rating. 1/2 the recommended for the BT3. Even if you could adapt the arbor hole, I wouldn't try it.

Thanks for the responses - I wasnt clear on the RPM rating of my saw. That is definitely not going to work.

So, part two - does anyone know of another blade that can be used to cut up this nail laden lumber?

if it has that much metal in it, you may do better getting a cheapo $7 blade at home depot for your circular saw. Either that or fish out all the nails. I can't imagine the wood being used for anything more than rough work if its got that much steel in it, so the circ. saw should be good enough, IMHO.

Oshlun has several steel cutting carbide blades that are pretty reasonable.

Two questions...how big are the nails? What will the orientation of the nails be when cut?

Ok, so that raises a question for me - does this mean I can use a plain carbide blade to cut through nails?

Also, more info: The nails are the twist kind used in really large pallets - the main boards are 4x4's and once ripped will be perfect legs for my hutches. The twist nails are impossible to remove with known methods to me.

Nails are 8 penny diameter and orientation would probably vary. These are twist nails from a nail gun.

Bosch claims their framing blades will cut more nails than any other. You can buy them for $10.

Good blade recommendations. One other thing to consider, which may be a vote in favor of using a circ saw for this instead of your BT - metal debris. Unless I was using a separator (and I am ) I think I'd be nervous about getting little bits of nail sucked into my DC impeller and hitting my filter or the dust bag. Maybe not a big deal, maybe others can comment.

little steel bits of nails as would be cut up by a blade certainly won't hurt the steel impellor. They're heavy/dense and should settle to the bottom bag of your two bag collector without hitting the upper bag. I would not think it would do any damage to a felt bag on the bottom (when using two felt bags top an bottom) or a plastic catch bag (if you are using some sort of pleated canister or cartridge filter on top)

Thanks for all the responses, I really cant comment individually right now because my posts are not showing up in real time - I believe they are being moderated.

I`m going to look for the Bosch framing blade and see how it does. I guess i`m a little nervous now about cutting through nails, but that Evolution circular saw did wonders in plate steel. I really should look into getting another one of those and just using it with a guide of some sort, as suggested earlier. Be a little nicer to my bt3. I do have a dust collector but it has ceased to work, probably needs a new motor starting cap.

I think most saw blade brands make a 7.25" remodeling blade that claims to cut nails. You could most likely use one on your table saw, depth of cut would be limited to about the short dimension of a 2x tho.
