How much do you have to clear? Would renting something for a day or weekend make more sense than buying a kit? I think when you get near 1/2" with no matter what special attachment you are at the upper limits of the capabilities of a weed eater? Most of the motors are just not built to deliver torque and other properties needed for very much work on things that thick.

I need it on an ongoing basis.... have used the circular saw method before and it worked great, just wondering if that is overkill or maybe the best way, thanks.

Whoa - that scares me, and I don't scare easily!

Here's what I'm thinking...

First of all, there's no way in the world to make that completely safe. Period. But since you're a guy, and you want to do it, you'll do it anyway.

Therefore, the need is to minimize risk.

One thing I see is that the arbor in the blade is larger than the shaft of your weedeater. You're going to need a sleeve shim, and it's going to have to be a precise fit, or the blade is going to be terribly out of balance. It looks like you're also going to need a reverse-thread lock-nut. A hardware store is probably your best bet for that stuff, but it's a long-shot.

Keep in mind that those weedeaters spin at a VERY high rpm. If anything goes wrong, it's probably going to go wrong in a big - and very painful - way.

Good luck.

A steel blade with sharp edges, spinning at 10,000 RPM, just a little off-center on the mounting arbor, and you are whacking it against branches and brush. What could possibly go wrong?

Ummm, Doc, I think I may need a few stitches.

Bulldog,
I used to have a blade setup for a commerical weadeater that was made for the unit. I used it once and took it off. Quite a bit of kickback, too dangerous in my opinion. If you decide to use yours, get some very heavy boots.
