Clever idea but overpriced like many of their OTTs. I have several of their products like squares and story sticks but I'll pass on this one since I can make one with some birch plywood and a bit of hardware.

Similar idea to the Qwas Square (below), and a couple of other shop made versions I have seen here on the FOG.

I think the idea is that you would leave it on the rail more often than not. Interesting...

They're just making a little hay till the FSK's hit !!

I'm often very negative about WP and the OTT offerings. $US100 for something you can make with 2 T bolts and a piece of plywood?? Give me a break

They should have placed an adjustable bar on the top side. That once you squared the Woodpecker square up, the bar on the top could be slid against the track and tightened down so there is a square reference built into the Woodpecker square. Gonna pick up some Aluminum plate and make my own.

The bar under the rail looks too short. I wonder how much deflection to square you get if you have side pressure at the far end of your cut.
Interesting tool, but I think I'll continue my method of using one arm of my parallel guides for this type of cut.

I just don't see it working very well in terms of precision.

The slightest error in squaring the Track Square will be magnified as you proceed down the guide rail.

I agree these are very over priced imho. I could set a CNC file up for something like this in about 10 min and machine it out of aluminum for about $50 a piece. For that matter I could laser them out of 1/2" acrylic or CNC then out 1/2" styrene. If that is all I made I could imagine doing 300 per day in my mahibe shop.

I feel they could have had a better OTT than this I am somewhat disappointed. I usually love and wish I could order all of woodpeckers OTTs.

If your cost to make is $50 then a markup of $49.99 is not too much as you put it. They would not be in business if they sold everything at cost. Consider everyone lucky that they exist and make products that a lot of people like.

If you can make them cheaper and want the hassle of dealing with people, shipping, returns, etc then go for it.

I was fiddling with something like this last year, it never made it to prime time due to lack of time. Fiddling included making a shop-made version from 2 pieces for 1/4" by 2" AL bar, then the more robust version I posted about. My observations from all this are:

• I never trusted the first version since it only took a minor whack to knock it out of alignment, something I did nearly every time I used it, often while jostling it into position against the sheet goods
• It took some time to get it set up dead-on square, I used a WP 16" by 24" square to do so and then tweaked it after a test cut

Also I agree that it would take something much longer than a 12" by 8" square to set up a 15" by 48" right angle, especially using the splinter guard to reference off of.

Just my and I am not a designer/professional/etc. but I have worked on the concept a bit. If they have overcome the mounting challenges sufficiently to assure that it can't/won't move, then my only concern would be aligning it easily. I would not reach for it if I had to keep adjusting or checking it every time I used it.

On the other hand, I don't have any issue with their price. After making up 10 copies of the second design and calculating everything they would have to sell for >$200. That is WP territory without even the red anodizing...

I'm relieved when a new OTT is announced and I don't lust for it.

FWIW...I think it'd be a rather nice addition to a guide rail for breaking down sheet goods.

I only have two issues with it. The first is the initial squaring of the Woodpeckers handle to the guide rail. Using a 1281 is rather hokey.    If you're off by only .005"-.006" at the 1 foot mark, you'll be off by .040"-.050" at the 8 foot mark on a sheet of ply. I'd just use a small Woodpeckers Saddle T-Square and 2 pencil marks spaced 95" apart on a 8 foot piece of plywood.

The second issue is how to maintain the perpendicularity while actively using the bulky assembled items. Because we're talking about an 8 foot lever arm (the Festool guide rail) it doesn't take much of a jar/bump to knock this assembly out of square. I think it will work, however, you have to be very, very careful when handling this assembly.

As far as price goes, I think they're in the ballpark. As a matter of fact I was quite surprised to see it under $100.  After watching the video, it appears that they may be using MIC 6 cast tooling plate which runs about $20+ per square foot. Add in machining time, clear anodizing, fasteners, extra bit & pieces, labeling, QA and packaging and the costs add up pretty fast.

Festool already makes an accessory that can do this and more : Angle Unit - 491588 $98

As far as price vs. features, the Festool clearly has a lot more features per dollar (it was $45 when I bought it).  As far as price vs. usefulness, I hope the Woodpeck one is a winner.  I may buy it and add my own self-squaring modification to it.  It's the nicest form factor I've seen.  Downside to the OTTs is that you can't read reviews before buying (unless they're the ones that really aren't one-time).

For reference, I've had a hate-hate relationship with my AU for years and would not recommend taking one if it is given to you free.  It will eventually cost you money by screwing up your projects.  Something like it that actually works is infinitely useful.

I think $100 for that is plenty. Looks like two would nest together nicely.  A large machining center would make short work of such a simple piece.  The two out of place holes to the left of the handle are to hold the material down as its machined...otherwise I'd bet the farm they'd mass cut them on a laser.

I do wonder of it would stay put after setup and if accuracy is really comparable to my current processes using a combo of my parallel guides, MFT, and Kapex.  Traveling lightly with less (unable to take Kapex and MFT), maybe it's a winner.

I see your guide rail connector, and cut it in half  .  Saved $80 bucks. 
I'm going to skip this OTT offer.

Sorry not real good at times with the Jig saw.  One day I will clean it us with my router.

Made two sets of 90 degree clamps that allow me to flip around and be used on either end of the rail.  The holes are for gripping/pushing/clamping. 

A quick alignment with a precision square and away we go.

That's a really slick idea...nice idea.
