I bought a 7 1/4" 24-tooth Irwin Marathon "WeldTec" circular saw blade with the intention of using it in the table saw to rip hardwood pallet stringers with embedded (and non-removable) nails. The packaging for the "WeldTec" blades specifically advertises the use of the blade for wood with embedded nails, as the teeth are welded on rather than braised. My saw does not exceed the blade's rated RPMs.

I knew that this was a risky task even though the blade appeared to be designed especially for it, so I installed all of the safety devices that were supplied with the table saw (blade guard, kickback claw, etc.). I did two rips, each one standing off to the side rather than behind the stringer. Featherboards were used to keep it flush against the fence and the table. As soon as the leading edge cleared the back of the table, I moved to the back and pulled the rest of the piece through.

The first rip was clean. But by the end of the second, the saw was obviously struggling and wisps of smoke started to appear from the kerf. After shutting down the saw, I found that all 24 teeth were gone from the blade.

Obviously, I'm disappointed in the product. Maybe it was unreasonable for me to expect this style of blade to perform this task, but it was advertised as being up to the task. I've seen a DeWalt blade (DW3191) similarly advertised as being a "nail cutting" blade, but I've not been able to find one for sale locally. Has anyone had a good experience with a particular blade for achieving a straight rip on the table saw through wood with embedded nails?

Was browsing in Lowe's this evening when I saw that they had the 24" Bessey Duoklamp on clearance marked down to $11.99. That's a deep discount and I'm thinking of picking up a handful of them. I've read mixed reviews, most of the negatives focusing on less clamping force than the Irwins and some issues with mechanism failure. At this price, I'm tempted to take my chances. Anyone have experience with these clamps?

Dang dude! I'm going to have to run by Lowe's here in Waco just to check. Lol.

Grizzly's newer C-frame 14" band saws have a handy tension-release clutch. So I decided to install it on my Harbor Freight saw. Here are a few pics from the process. (BTW, I am convinced this mod will work on pretty much any 14" Asian import band saw.)

I can't give an honest review yet because I really haven't gotten to put it through its paces. There are some disappointing Harbor Freightisms, though. The lower wheel was unbalanced out of the box, and the upper blade guide bracket was slightly skewed and had to be straightened with a pair of pliers. But those were fixable. So far, my biggest complaint is that the miter slot is 0.65" rather than the standard 0.75", and the miter gauge that comes with it is absolute garbage. So I'll have to build my own miter gauge, modify the bar on a decent one, see if someone sells a decent gauge in that size, or just replace the table.

But the motor is strong, the wheels coplanar, the blade tracks well, it's quiet, and (once the wheels were balanced) doesn't vibrate much.

Incredible
This video is amazing and clearly shows the effects of a chip breaker with a much steeper angle on the front of it (think snow plow rather than ramp) and setting it closer to the edge of the blade than “conventional wisdom” would have suggested. The video very clearly shows that the chip breaker ...

Very cool. It looks like they did this surgery around the time Robert's heart started beating.

Love it! Probably even funnier if you know cricket, I guess.

Picked up a stationary 6" jointer that has seen better days, and I'm part way through cleaning up the tables. One down, one to go!

Thanks +Charlie Lenz! That looks like what I figured I was going to do, except I figure I'll use plywood or even particle board, strap the chute to the motor bracket, and attach a dust port to the end.

Is there such a thing as a through-the-wall ambient air cleaner?

I have a detached 2-car garage with a special shop area on the side. There is an interior wall separating the garage side from the shop side, and one set of double doors between them.

I installed a 2-ton "mini spilt" air conditioner/heat pump that is big enough to cover the whole structure, but the air handler is on the garage side on the back wall, while the double doors between the two sides are closer to the front wall. As a result, there's not enough air circulation between the two sides for the shop side to get all the heating/cooling benefits.

In related news, I've been doing a lot of sanding in the shop and despite at-the-tool dust collection, I'm still getting a lot of suspended particles that make the air hazy and end up settling everywhere.

I'm wondering if I can kill two birds with one stone by getting an ambient air cleaner and installing it through the wall, near the back of the garage, so that the inlet is on the shop side but the outlet is on the garage side. This should significantly increase air circulation between the two sides and help draw the conditioned air into the shop. I'm hoping it will also effectively filter suspended particles out of the air.

Has anyone ever done something like this, or have any thoughts about the idea? I can't find anything online discussing this particular issue. Thanks!

That sounds like the sort of thing I'm going for. The conditioned air gets into the shop through the double doors, which are left open all the time. I think that if air is forced from the shop side into the garage side, it will continuously circulate the air between the two sides.

Cheapo weights for balancing my lower band saw wheel.

Glad you've turned it into a usable tool.

Is there any way to block the "What's hot on Google+" feature? I really like this platform, but I hate how it spams me with very kind of pointless nonsense I left Facebook to avoid.
